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 :

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,
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:
- 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.
- 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.
- SCSI termination errors. This has become less likely with the advent of self-terminating SCSI hardware, but it shouldn’t be counted out.
- 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.
- 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.
- 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.
- 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.)
- 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.
Recently I found another solution to this problem that really worked for me. It’s on the next page…

Thanks for the help on this page.
I tried everything and the ‘disable write caching’ under hardware/properties/policies on my SATA Seagate external drive worked -the ‘Write Delayed Failed on J:/$MFT’ error has ceased. My 300gb of data appears to be safe now!
Thanks you.

Hi all,
Will not the Max128K Filter reduce the data transfer speed to the external drive.
I have Transcend StoreJet and facing the Windows – Delayed Write Failed problem. I usually end up rebooting the system because it hangs each time.

I had the same problem
I did chkdsk.

I would like to posit another cause and solution. I have made several of my own external drives becuase of this recurring issue.
What I have found to be the cause in commercially produced external drives is heat. Many of the drives today leave out a critical piece of hardware, a small case fan to move air through the system. I had an old external device that had two small fans and never had a problem with it until the internal fans went out. Then the problem began to occur during long file transfers. I replaced the fans and the problem went away.
I purchased a new external drive later no fans just a few poorly place vent holes and I had the problem with any transfer that lasted more than 5 to 10 minutes. I cut a hole in the side of the box and installed a 30mm fan. No more Delay read/write errors until the fan failed.
The bottom line look for a system with a fan or buy a box with a fan and add your own HD.

well just to update about this, i’ve tried every solution including the cacheset settings and it still screwd up showing me with the write delay error… however, i decided to pop open my HDD take note it’s a WD500GB My Book because i thought it could possibly be a heat issue since this drive has no internal fan. So far it’s working great, all i did was pop the case open and it seems to stay cool enough now, working over 2 hours without giving me an error where it would ussually give me the first 10 minutes of being plugged in if not instantly..
Now if you’re having trouble accessing your drive right away.. as in as soon as you plug it in and autoplay pops and then you get the write delay error this might be your boot sector that’s been damaged.
If you didn’t reformat your drvie after you bought it you should be using a FAT32 format. There’s a microsoft solution to this where you can revert back to a backup fat32 sector that is stored on sector 6 of the drive.. To do so you require a simple utility contained in your windows xp setup disc.

What happened to my post?

@Andrew: Hi! Your last comment was posted on http://www.gibni.com/windows-delayed-write-failed-2 and not here! From the info you’ve provided in your comment, I believe that you should check your hard disk with a checkdisc utility like windows’s built-in chkdsk command. On the other hand try to use the cache set utility as mentioned on the http://www.gibni.com/windows-delayed-write-failed-2 post and do it before you connect your hard drive. You might also try to connect your hard drive to a recent PCI – USB expansion card, as this problem is sometimes related to the USB Controllers. If all fails, try to connect directly your hard drive to your motherboard with the IDE (or SATA) cable.
As other visitors also mentioned these errors might happen due to temperature increase on the disk, see if you can do something to keep your hard drive cool.

It was never clear to me in your post but were you able to again access the files on your external hard drive after the fix? I’m in panic mode right now since my computer is not able to access the external hard drive and I get the error message you posted. I haven’t tried the fix yet but assuming I do and I don’t get the error after restart, should I expect my files to still be there, corrupt, or gone??
Thanks,
Phill

@Philip: If you restart your computer, you would probably get your drive and files back. in some cases the drive file allocation table becomes corrupt, not because of the solutions proposed here, but only due to the error itself. All solutions provided to you on this website are safe and tested. Anyway, let me assure you that even if you loose access to your drive and even if it shows it as an unformatted drive, you can always get your files back! (be carefull NOT to format the drive or write ANY data on it if you don’t find your expected files on the drive!)
In the following days, I will publish another article that is explaining all the possible solutions for this issue. And soon after, I’ll post another article on how to recover your files from a corrupted hard drive (even from a formatted one). Stay tuned.

Overnight unattended transfer of several comparatively compact image files, after the DWF etc. and kybd lockout, upon power off-on, the VIA/SATA150/RAID1 controller disappeared and so did the WD 250GB RAID1 array. VIA/SATA still in HKLM/…/CurrentControlSet in registry, but gone from BIOS. reinstall VIA/SATA/RAID driver. array still broken and drives will not link master – mirror. other problems beyond the current thread, no?
Waiting for your next article, on recovery.

Anyone can suggest, is it the same error like external hdd. coz i am also facing “Delayed Write Failed” error , while files are archiving or making backup from Harddisk to DVD-RAM with timer according to software program. But the DVD-RAM itself show in My Computer as Removable Disk (E:) . That DVD is double side and panasonic DVD-RAM LM-AD240ME. Is it can solve with Cacheset ?
Thanks

I am so glad I found this article. I was starting to think that I had wasted money on the MyBook 1TB. After installing the driver, and adjusting the registry settings, all works well. Thanks a bunch for investigating this, and providing a simple solution!

I have the same issue with a StarTech SAT2510U2 external SATA enclosure. I’ve tried every solution listed in this article and everywhere else. I’ve tried two different physical SATA drives.
I *think* I may know what the problem is. The USB cable was running fairly close to a set of speakers. I’ve rearranged and we’ll see what happens.
Is there a way to reproduce to error messages on demand, for test purposes? Large file transfer?

Here is a very simple fix that I found on Toms Hardware.
This solution worked beautifully, at least it seems to so far, to fix my 500 GB Western Digital USB Mybook, which was throwing up the Delayed Write Failed error (even tho write caching was disabled). In fact, XP had begun refusing to even allow me to Explore my Mybook.
My problem apparently was related to System Restore trying to write to the USB drive. So I needed to stop System Restore from trying to protect the USB drive.
THE FIX: To prevent System Restore from messing with your USB drive: Start, programs, accessories, system tools, system restore, then on the left side you see Change Settings, then highlight your external drive and uncheck Monitoring for that drive.
When I followed this procedure, I plugged the drive back in and the problem disappeared immediately.

I have been having this problem for some time. It happened on two different external drives ( a western digital my passport and a generic USB 2. firewire drive). I had the generic drive with my previous pc running window 98 and the problem only started on the new xp pc.
Switching the system restore off has fixed this so many thanks Tim (and Toms Hardware)

Hia everyone. I had the windows delayed write error /$Mft on my Seagate ST315005FPA2E3-RK Ext 1.5TB Freeagent Drive. I’m using Windows XP SP2 and the drive has SATA IEEE1394 and USB2 ports on it. I was using the USB2 cabling thru a powered USB 8 port adapter. I’ve been using this drive for more than a year, and never had a problem. (I also have a second drive, exactly the same Freeagent drive, used as a mirror- but was not connected at the time of the errors). It seemed like the directories and files were disappearing more and more, every time I restarted the drive. I finally disconnected the USB cable from the powered USB poit adapter and plugged it into the Main board. All is well. my Mft index was rebuilt (apparently from a backup on the drive) and all files are accessed. Apparently the USB Port adapter is bad. Hope that helps someone. Thanks for all the ideas..

Hi Guys,I started getting this problem with my newish 1TB Western Digital Elements external hard drive.Folders were coming up empty that weren’t empty before and that pi**ed me off!
However after reading a few of the posts here I tried plugging it into a different USB port and whaddaye know?! It’s working perfectly now AND the missing data is showing up again.
Hallelujah brothers!

Hi all. Just want to say thanks to all for the solutions provided. I’ve been to many sites and they all only have one solution. This is the only place that gives many solutions to the same problem. I’m hoping to try some tonight on my internal Seagate 500gb sata drive. Hopefully something works.
Keep up the good work.

I have 3 almost identical HP Pavilion XP MCE machines, all with the space for their Personal Media drive. I have installed a 500gb one in each machine. All machines are completely updated. I discovered that one hasn’t run a successful Backup for a while (it’s used only as a big TIVO), and the issue is Delayed Write Fail errors. The bulk of the C drive ‘source’ data is dvr-ms files, each about 2gb. The K drive, the internal, so to speak, USB drive, was the destination drive, and also where MCE was recording files for the last 6 months. Lo and behold, magically the TV Recording Storage Setting was, I found, back to C:. This happened before 9/13/09, when the first recording in a week was made.
Anyway, I tried simply copying TV files to K and the error continued. I tried, for kicks, copying across my network to a different PC, and also got the error, though I am not sure if it was to that machine’s C or its own USB internal drive. So I decided the error was not destination-related. Apparently this was wrong?
I called HP, who pointed me towards 330174 on MS Support. I also opened a case with MS, because at this point it seemed related to the large update recently out.
Disabling write caching, reenabling it, etc etc etc, nothing works. This machine is 3 years old or so, the USB drive was installed this past spring. My other machines are not having the problem.
All my workaround attempts have caused even a no TV, small-file only Backup to run for days. No one seems to have commented on that; if disabling write caching doesn’t affect other people’s thruput, what else could be going on here?
Thank you.
