I bought a 500 GB Western Digital My Book Premium external hard drive. For few days, everything was working fine, but suddenly the Delayed Wrifte Failed error started to pop up and my drive was no more accessible. Here’s the error displayed on Windows:

“Windows – Delayed Write Failed : Windows was unable to save all the data for the file X:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.”

 

I searched a lot but nothing came up. I had to restart the drive, disconnect and reconnect it again to make it work which was a lot of pain!

 

Well, before we get to the working solution (for my case), read and see the following :

From Others:

According to the article “8 common causes for ‘delayed write failed’ errors” by Serdar Yegulalp , from SearchWinIT.com which was published on 01.05.2005,

wd book 2 Windows   Delayed Write Failed   Solved!

Windows uses a special subsystem for certain disk functions, which caches write operations and performs them when the system is idle. This can improve system performance, but it’s typically turned off by default. The term for this kind of operation is “delayed writing”.

You can see how write-caching is handled for a particular volume by right-clicking on the icon for the drive in the “Disk drives” subtree of the Device Manager and selecting the Policies tabs. The options typically are “Optimize for quick removal” (everything is written to the drive immediately) and “Optimize for performance” (writes are cached).


The first option lets you quickly disconnect drives — for instance, hot-pluggable USB “pen” drives — without first disconnecting them via the Safely Remove Hardware icon in the system tray. If all the options are grayed out, this means write-caching is probably handled at the discretion of the device driver. (You can see more information about the way the defaults for write caching work in the Microsoft article, “Windows XP and Surprise Removal of Hardware“.

In Windows XP, the system may pop up a “Delayed Write Failed” notification balloon, which means that something has gone wrong with the delayed-write system. This does not always mean there has been a fatal problem, but you should take it seriously.

Some common reasons for a delayed-write failure are:

  1. Problems with a device driver, especially a SCSI or RAID device driver. Some RAID device drivers are known to issue spurious “Delayed Write Failed” errors in XP Service Pack 2. Most manufacturers have been alerted to this, so check to make sure the disk drivers are up-to-date.
  2. Cabling problems. A faulty or broken cable — especially for an external USB or Firewire enclosure—can generate this error. It can also happen if the cable is too long, or if it is hooked up through a hub that isn’t up to spec. Another possible culprit is if you have a UDMA drive that requires an 80-pin cable, and you are using a 40-pin cable.
  3. SCSI termination errors. This has become less likely with the advent of self-terminating SCSI hardware, but it shouldn’t be counted out.
  4. Media errors. This is the worst possible scenario — essentially, drive failure. If you can garner statistics on the drive via SMART (such as SMART & Simple (http://www.beyondlogic.org/solutions/smart/smart.html), you may be able to determine if there’s a mechanical failure in the offing. Gibson Research’s SpinRite tool (http://grc.com/) is also useful for assessing media errors, but be warned: It may take a long time to do a thorough test.
  5. BIOS settings on the computer are forcing faster UDMA modes than the drive controller can handle. This is unlikely, especially with newer hardware (which can support UDMA far more flexibly), but it can usually be fixed with a BIOS upgrade, or by resetting the BIOS entries for the hard drives to auto-detect settings. Devices set to UDMA Mode 6 that produce this error, for instance, might need to be set to Mode 5.
  6. Controller issues. I’ve observed that USB controllers that contend strongly with other hardware can produce this error. In systems that have both “long” and “short” PCI slots (i.e., 64-bit and 32-bit), try moving the USB controller to the long slot. Older PCI cards will not fit in such a slot.
  7. Memory parity issues. If the problem appears after installing new memory, the memory in question may be faulty or not of the correct type for the motherboard in question. (This may go hand-in-hand with other problems such as random lockups, too.)
  8. The LargeSystemCache Registry tweak and ATI video adapters. One peculiar set of circumstances that has been observed on multiple machines with ATI video adapters and more than 512MB of memory involves the LargeSystemCache Registry setting, a DWORD entry found in: HKEY_LOCAL_MACHINE >SYSTEM >CurrentControlSet >Control >Session Manager >Memory ManagementThis setting governs the amount of memory set aside by the system for certain kernel processes. If it’s set to 1 (which allegedly improves performance on systems with more than 512MB of memory), it can cause data corruption on some systems, and produce the “Delayed Write Failed” error. Try resetting it to 0 if it’s been set.

Now that you have read the 8 common causes for this error, let’s see about what worked for my case.

    You guys know that Seagate has a hardware failure on their 500GB and 1TB (and possibly 1.5TB) drives that?

    Same issue happened to me with the Delayed write failed issue occasionally since Sep 2009, and only this month did I discover that it is a Seagate issue!

      Your problem is “Seagate”. I’ve had nothing but problems with their harddrives.

    Hai guys, I also experienced the same problem with my usb flash drive “Delayed Write Failed” and when i troubleshooted it everything seems alright.

    Please check whether other USB devices drawing too much power from the hub?
    The device you are trying to use might require all the available power or bandwith that your USB bus can provide. If other devices are connected to the USB bus and are drawing power from it, the first device might not work.

    If any other devices are drawing power from the hub, try disconnecting them, and then see if your device works.

    If this solves the problem, you might want to obtain a USB hub with its own power supply, so that you have adequate power for all devices.

    Hope this will solve your problem…

    My problem was as follows: all music was stored on an external usb drive ..as soon as our newest ipod shuffle was connected it would bring about this error on the drive (not the shuffle)…after speaking with apple it comes down to one thing..they did not essentially design within USB specs and the newest generation of shuffle sucks up ALL of the power the 2.0 port can muster, not leaving enough for the external drive…thereby causing the error.

    The solutions? moving all the files back to the main hard drive defeats the purpose of the external drive…
    a firewire card moves the power requirements to separate
    or another pci usb 2.0 hub could be added ..either of these
    may require an upgrade to the power supply
    one possible solution which I am currently investigating is a USB 2.0 hub which many people tell you to remove in trying to solve this problem, however, it is my hypothesis that a powered USB hub (yes another plug which is just for the hub itself) may resolve this issue…provided adequate power for both the shuffle and the drive. I hope this helps alleviate at least some of the frustration anyone in a similar bind has. My conclusion? If the new Shuffle were not designed to take all the power…there would not be a problem (my older shuffle as well as nano works just fine, not to mention the new kindle I gave my wife …)

    Well the max 128k solution WORKED FOR ME!!! So far no more annoying windows delayed write failed errors! I was getting the error on an external FireWire (SBP2) drive. Thanks very much for sharing the solution with us!!!!

    my simpletech 500gb external USB HDD has been crapping out with the dreaded “delayed write failed” and since it’s now been discontinued there was no more support or drivers update either.
    Been reading up on the myriads of solution offered online including here but none works! I’ve got WinXP SP3 fully loaded.
    What actually solved it was :

    Go to My Computer, right click on the SimpleDrive, click Properties, click on Hardware tab,
    highlight STECH Simple Drive USB Device, click Properties, click on Policies, check Optimize on Performance. Press OK.

    You’re done.

    Ultimately I had to replace my hard drive which was creating these problems but fortunately I had backed up the whole drive before it stopped working..

    I added an unpowered USB 500GB drive to my Presario, and got continual Write Delay Failed messages. I found the Max128K filter, and it seems to have worked. I did have a problem with the home page of the author, though. After he explained how to install the filter, he wrote:

    “All Done! If the enclosure was plugged in while you were making all the changes, just disconnect it and reconnect it again to load the filter driver.”

    When I did this, I lost the drive completely, all my email folders included. I had to use System Restore to get it all back. But the filter itself seems to have worked. I tried to contact the author about his questionable instruction to unplug the device — rather than reboot, for instance, — but the email address given doesn’t work. Still, I haven’t got any Write Delay Failed messages since — and it’s been at least thirty minutes.

    I have 3 WD 1TB MyBook, when I was transferring large size data from my desktop running winXP sp2 to one of them it hanged up on me and after restarting it gave the write delay error msg. I already know the cause is the cable I used. And now whenever I connect it to my desktop it appears as a blank drive w/o volume. I was still able to transfer the files from it by connecting it to my notebook running in linux and trasfer it to the other 2 MyBook. The other 2 works fine on my desktop so my question is what can I do to work again on my desktop, I’t does not allow me to format it on my desktop is there a registry entry I need to change or delete?
