How to Fix Western Digital Caviar Green Bug

This information will be of interest to all those who use hard drives Western Digital Caviar Green range. Recently I discovered that these discs suffer a number of problems with no official solution from Western Digital that many people are unaware, and that could eventually cause serious data loss.

Guide Preview of Fixing Western Digital Caviar Green Bug

There are three main problems:

• LCC and RAID: affects ALL WD Caviar Green, without exception everyone who has a Caviar Green has to apply the solution of the LCC, and if it has it in RAID, also apply the solution for RAID..
• Poor performance: affects some specific models If your hard drive has a ridiculous performance, try to process an RMA because there is nosolution.

1. Poor Performance

After formatting, all hard drives work well and have optimal performance. But over time, especially as it is giving them use, begin to suffer performance problems. In the official forums there are users that Western Digital announced poor transfer speeds around 2MB / s, freezing and even system crashes.

Models affected:

• WD15EADS (1.5TB 32MB cache), especially 00P8B0 submodel (except submodel 00R6B0)
• WD15EARS (1.5TB 64MB cache), especially 00P8B0 submodel (except submodel 00R6B0)
• WD20EADS (2TB 32MB cache), especially 00P8B0 submodel (except submodel 00R6B0)

Many manufacturers of NAS devices these models have withdrawn their compatibility lists. Synology NAS indicates that its only support the submodel 00R6B0 of these discs, which is the only unaffected.

Thecus has eliminated them directly from your list.Indicated on your QNAP compatibility list that have problems WD15EADS slowdowns, crashes and poor performance.

No solution

2 Death excess heads parked (LCC)

To save energy, the entire range Caviar Green uses a somewhat aggressive but fairly common method, consisting park the heads in the security zone once after some time of inactivity. 

The problem is that the parked is configured to be done every 8 seconds! Hard drives support a maximum number of heads parked over its lifetime, and in the case of Green Caviar parked 300,000 guaranteed operations before mechanical failure occurs.

The number of times a disc parks the heads is registered by the value of "Load Cycle Count" (or LCC) of SMART. Users have detected a rapid increase in this value, calculating that in less than two years may exceed the figure of the 300,000estimated to be parked within the lifetime of a disk, with only about 4 or 5 hours of use. 

In my case, my hard drive is connected just a few minutes a week to back up and dump some data, and in a year I have planted a value of 10413 (the number of hours indicates the SMART not block me and I do not think it's right above):

Solution:

1. - Lower the WDIDLE3 utility Western Digital page: http://support.wdc.c...sid=113&lang=en
2. - Copy the utility to a floppy disk, CD or USB boot with MsDOS or FreeDOS
3. - Switch off all PC hard disks, connected to plate and let only those who want to fix
4. - Start in MsDOS / FreeDOS and run:   wdidle3.exe / s300 

Sometimes it seems that there are problems with the parameter according to the version of the tool. If it does not work with "/ s300" test with a space in between, "/ s 300".

NOTE: In many places it is suggested to use the parameter "/ d" to completely disable the function, but this seems to cause major performance problems, and in some cases parked constant heads, so we recommend using "/ s 300" to set the time parked head to 5 minutes, which is the maximum allowed.

3 Corruption of RAID Volume

This problem only affects other users wishing to use these hard drives in RAID. Western Digital Caviar Green warns that the range does not support RAID volumes, and it invites us to buy the business range RE-4, significantly more expensive. The real reason is given by the way in which the Green Caviar errors manage read / write.

All hard drives have an additional space sectors beyond the actual disk space. These additional sectors are used to relocate information when a problem is detected in a physical area of ​​the disc. 

For example, if you type in the field # 10 problems are detected, it is marked as invalid and relocated to a reserve sector. The same goes for reading, trying to retrieve the information from the damaged area and relocating it once it has been achieved (recoverable error).

These operations take a hardly predictable time, from a few seconds to several minutes.'s Problem for a RAID volume is expected to answer the hard drive within a limited time, usually around 10 seconds. If there is a disc that appears to be frozen or no response after a read / write, the RAID controller is marked as invalid and calls for its replacement and rebuilding the RAID volume. 

Use Caviar Green hard drives in RAID can lead to problems data loss because it can do that to a recoverable error, the RAID controller discard the hard disk and marked as invalid. If a RAID-0 we will have a big problem, and if it is a tolerant RAID on a hard drive and drop two also.

The solution is to limit the time of data recovery. That is, what matters is that the hard drive try to make a quick recovery of the sector, and if this is not possible before the problem rises when the RAID controller so that it is she who makes the decision of proper recovery. Here's how the disks are configured in the RE-4 range, cutting recovery by 7-8 seconds.

Solution:

- Lower the WDTLER usefulness of this page: http: //shifteightgen...top-hard-drives
- Copy the utility to a floppy disk, CD or USB boot with MsDOS or FreeDOS
- Switch off all PC hard disks, connected to plate and let only those who want to fix
- Start in MsDOS / FreeDOS
- Run First "tlerscan.exe"
- Execute after "tler_on.exe"

-------------------------
And the silence from Western Digital about this problem is worrying.
PS: I made some screenshots (before reconfiguring the idle3) SMART values ​​Caviar Green (WD10EARS) and another WD (WD3200AAKS) to use with the operating system for 2 years.

WD10EARS Caviar Green:

WD3200AAKS:

In those 8 hours of actual use (I plug just to make backups, e-sata via a dock), the Caviar Green had 234 "parked" head.The other for 430 days and 20 hours of use is 1455.
Eloquent.

10 tricks to optimize your SSD and improve its performance

If already, with an SSD we take more advantage of our equipment, here we are going to give you some tips so that you get more performance from these disks.

See the best sellers in Internal Solid-State Drives.

Your PC still doesn't have an SSD? Admit it, your computer is from another era, that of slowed computers and the internet at a snail's pace. Whether laptop or desktop, a computer with a Solid State Disk or SSD disk is the best option to fly over the network. If you want to optimize your SSD to reach its maximum speed, follow these 10 tricks that we give you below.

What is an SSD?

For those who do not know very well what these types of disks are, they are data storage units, like a normal hard disk, but with higher performance and faster writing and reading speeds. They have no moving parts, so they are more resistant to shocks. The fact of having very low latency and access times makes them perform much better. All this is thanks to its flash memory, which differs from plates or magnetic disks in those conventional hard drives use.

Solid state hard drives or SSDs can reach speeds up to 100 times faster than a “normal” disk, just like the next generation NVMe PCIe 4.0 SSD drives. The writing speed in these cases reaches up to 7000 MB / s, something that is impossible to achieve with a hard disk of a lifetime. To reach these quotas, it is essential to know how to configure your SSD, but do not worry, because today we are here for that. 

Whether you have an SSD installed on your computer or if you are thinking of installing it, here we are going to give you some recommendations so that you can speed up your hard drive. In addition, we are also going to give you some tips to increase the life of your SSD, something that should be taken into account. Some of the notes that we are going to give you next carry a certain level of knowledge regarding the fiddling of the configuration of your computer.

1. Speed ​​up your SSD by enabling AHCI 

The AHCI (Advanced Host Controller Interface) is the Advanced Host Controller Interface. It is important that this is active if we want our Windows to favor our SSD so that it performs more. To enable this option, we must access from the computer's BIOS and activate it from the configuration or settings. In any case, if it can be, it is better to activate the AHCI before installing Windows on our PC. 

If it is not possible, there would be no problem as long as the BIOS allows us to activate it anyway. We can find this option in different places within the BIOS settings, but normally we will find it in the Advanced Options section -> SATA or storage configuration. 

2. Enable TRIM to increase the life of your SSD

It seems silly, but the TRIM prevents the degradation of the hard disk, so, if we want to extend the life of our SSDs, enabling it is a good idea. Windows 10 should have this option enabled by default, but if you want to make sure you can do it from the system command line. We open a command prompt window and type the command "fsutil behavior set DisableDeleteNotify 0". Remember to run it as administrator. 

3. Enable or disable disk defragmenter?

The disk defragmenter has always helped us to organize documents on our computer and remove cache. About having this option enabled or not when we have an SSD installed there are many theories around the network, but with the latest changes introduced in Windows 10, the correct thing to do seems to leave it enabled. 

With the arrival of SSDs, it was found that the defragmenter caused a considerable reduction in the number of read and write cycles, so it was detrimental to have it activated. It made the disk somewhat slower and a more heavily loaded process that caused the SSD to wear out quickly.

However, with Windows 10 this problem has disappeared. The defragmenter is now called "Drive Optimizer" and it does not harm performance or wear out our SSD. As we think this is a good thing, since the process that is carried out is different from that of defragmenting the SSD, it is best to leave it activated so that it runs periodically. We can change the settings to run daily, weekly, or monthly. We recommend the latter.

4. The Prefetch and the Superfetch

The Prefetch is a service in charge of copying files that have been recently opened and storing them in an area adjacent to the hard disk. It serves so that when they are accessed again, it can be done quickly.  It is not necessary to have the prefetch activated because the SSD does this job and takes the same time to access a file. This is why this service loses its meaning a bit, so having it activated is only consuming RAM.

The Superfetch is a service that handles preloading widely used programs on our team. Like the prefetch, it uses memory space to accelerate that fast start and it is quite absurd to have it activated, since we are eating a space of RAM that our SSD can take advantage of, since it is capable of doing the same just as fast.

To deactivate Prefetch and Superfetch, open the Windows "Registry Editor" and navigate to the following path: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ PrefetchParameters. Once here we will set the value 0 to the EnablePrefetcher and EnableSuperfetch options. 

If the EnableSuperfetch value does not appear in the registry, then disable the Sysmain service in Start -> Services. 

5. Update the SSD firmware

This seems obvious, but some people overlook it. When we install an SSD in our computer we have to make sure that the firmware is up to date and thus can offer absolute performance. If we do not know if our SSD is up to date we have to go to the website of the manufacturer of our disk and look for updates available.

Manufacturers can upload updates of their products to their official websites, it is good that we are aware of that. To know the version we have of SSD (if you do not know), there are online tools that can provide you with that information. Once we know the version we have, we can see if there are new updates available and keep our disk updated. 

6. Disable the search index of your SSD

By default, Windows makes an index in which it points in which area of ​​our SSD each of our files is stored. This made a lot of sense when using slow, mechanical hard drives, but thanks to the SSD's read and write speed, it is no longer necessary to have it active, therefore, if you want to optimize your SSD, you will have to disable it.

How do you do this? Well, it is very simple. Enter "My Computer", find your SSD hard drive and enter "Properties" by pressing the second mouse button on it. At the bottom of the "General" tab you will find the indexing option, you just have to uncheck the box and apply the changes.

7. Disable Windows fast startup

When we put our laptop to sleep or close the lid, Windows saves the state of our activity in a small hibernation file. This means that every time we do it, we are spending read / write cycles of our SSD. Although the effect is not at all worrisome, in the long run it can affect the lifespan of the hard drive. 

In this case you must decide. If you prefer a somewhat faster system resume in exchange for a bit of the life of your SSD, leave the fast boot option enabled. If, on the contrary, you are more concerned about lengthening, even if only a bit, the useful life of your SSD, then deactivate it.  You can do it in Start -> Control Panel -> Choose the behavior of the start / shutdown buttons -> Change the currently unavailable settings. After that uncheck the option "Activate fast start" and press Save Changes. 

8. Disable paging file cleanup

There are some options in Windows that are no longer necessary if we have an SSD disk. To increase the general performance of our computer, we can deactivate the cleaning of the paging file , as this does not improve the performance of our computer, due to the high speed of solid state disks, but it does consume write cycles. 

Disabling it is as simple as entering the "Registry Editor" and looking for the following key: Computer \ HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management. Set the “LargeSystemCache” and “ClearPageFileAtShutdown” values ​​to 0. This doesn't speed up your SSD, but it will save you a good number of load cycles throughout its useful life.

9. Configure your SSD cache

To optimize your SSD and find the balance between life and speed, we recommend disabling the write cache.  This option speeds up access to the data on the hard disk, but taking into account the read / write speed that is handled today, it is no longer necessary to keep it active, since all it does is consume read and write cycles. 

To disable the SSD cache we have to enter its properties and select the Hardware tab. Click on your hard drive, click on properties and then on the option to change settings. Finally, deactivate the option "Enable write cache on the device" and click OK. 

10. Check the status and speed of your SSD

How can we know if these changes are affecting the performance of our SSD or not? Well, my simple, measuring it through a reading and writing speed test.  The best known program to do this is called CrystalDiskMark, and it is completely free. With it you can perform performance tests in a very simple and fast way. In this way, you can accurately check if all the changes made are serving to optimize your SSD or not. 

As far as the longevity of your SSD for Windows is concerned, we can use tools such as CrystalDiskInfo or SSD Life , which provide us with technical information about the health of our hard drive. So we can check if our SSD is close to reaching its useful life or not. In any case, remember that an SSD disk can function optimally for at least 10 years, as long as we take good care of it and make normal and current use.

Best cheap USB microphone for streaming 🎤 Trust GXT 232 Mantis

My choice for the best usb microphone for streaming is Trust GXT 232 Mantis wich offers us the best sound quality without spending a fortune.

 

Trust GXT 232 Mantis. Live Broadcast Microphone Review 

See this review in Spanish: Reseña 🗣 Micrófono BARATO para Streaming 🎤 Trust GXT 232 Mantis

 The Trust Mantis GXT 232 is made almost entirely of plastic, except for the grille that covers the microphone diaphragm. While the lack of metal or a material harder than plastic may indicate inexpensive equipment, the strength of the material used does not give the impression that the material is brittle. The microphone does not have volume or gain controls and its connection is USB type to simplify its operation as much as possible. 1.5-meter braided connection cable; It contributes to its durability and prevents damage from bending the cable or accidentally stepping on it with certain elements during our installation that would damage the cable. 

Concluding about the best cheap usb microphone for streaming

The quality is, of course, very good, giving it a good value for money. As a last comment about the Mantis GXT 232, we can only say that apart from the practicality, they do not require anything more than connecting them to our PC or laptop, or even to a PlayStation 4.

 

This mantis allows us to exponentially increase the quality of the sound if we compare it with the microphone integrated in our laptop. Although it is not a professional microphone, the jump in quality that you get in your live transmissions is impressive.

External hard drive does not boot: why and what to do

Try to restart

One of the most common reasons why the external hard drive does not boot is simply because the operating system has not been able to read it. When it comes to these cases, the problem does not lie in the hard disk, but in the reading of the device. To fix it, you just have to restart your computer. The most common is that, by doing so, you can already boot the external hard drive.

If you still can't get your hard drive to boot, the next step in the chain of possible reasons why it's not working is to check your connections. There are different ways to connect an external hard drive and depending on what type it is, you should check accordingly.

If it is a USB-connected external hard drive, you might want to check if the cable connecting it is fully operational. One way to check this is to try using other USB devices on the same input jack, and if these work, try connecting the hard drive with a different USB cable.

External hard drive won't boot: why and what to do - Check the connections

Find out if you have the optimal drivers

If you've already tried a restart and checked that the cable and connections are OK but it still won't boot and you also see that the LED is on, the problem may be with your drivers. It is common that, if you have just formatted your computer, your system drivers have been uninstalled. Luckily, there are many options on the Internet for you to download a specific driver for your computer and install it on your system. Once you have it on your computer, you will need to access and update the drivers so that it can read and enable the external hard drive to boot.

Make sure there isn't a problem with the splitters

If after all this the hard drive still won't boot, the next logical step is to think that there is a problem with the starters. In this case there can be two scenarios:

• If the hard drive is new: it may be that the computer does not recognize it. To do this, you have to activate it and assign it a brand-new format through the "Disk Manager" section. Where "unassigned" appears, you must make sure to enter "New simple volume" so that, in this way, your system assigns to that new device some starters that manage to boot it correctly.
• 
  If the hard drive is an old one: There may have been some problem with those working splitters. In this a case you will want to start a system check by entering "Command Prompt" or CMD and enter the code "chkdsk [drive letter:] /R"

Use data recovery software

The possible solutions to be able to boot the external hard drive are over and, at this point, one of the solutions that you can have when it comes to being able to solve the situation is to use software that allows you to recover the data that you have on the disk. In this case, you will recover all the information that has been trapped or damaged on that disk through third parties.

Send it to technical support

If you have followed all these steps and still have not been able to start your external hard drive, it is most likely that it is not a specific and external problem, but that the disk is damaged either by some environmental, technical factor or a blow. In this case, the only possible solution is to take it to the technical service, where the professional computer specialists will take care of opening it and thoroughly reviewing it, trying to recover the entire content and fixing any physical or internal problem that had been preventing the reading and booting of the hard drive. external with computer or other devices.

Now that you know the possible reasons why the external hard drive does not boot and what to do in each situation, we recommend you read this other post on How to format an external hard drive.
