Windows Delayed Write Failed – Latest Solution
UPDATE: Latest article: Window Delayed Write Failed – Solutions –>
A while back, I wrote a post about the “Windows Delayed Write Failed” error message, and I presented ways to resolve the problem. That worked for many people.
Recently, after installing a fresh copy of Windows XP (with SP3), I got the same problem, and I tried everything I knew to solve it, but no luck!! As the problem’s to do with the USB caching and data transfered from the cache to the disk, I went to my favorite search engine again!
The last thing I found, which solved the problem is to use a piece of software from SysInternals (actually aquired by Microsoft) called Cacheset !

Easy Steps to do:
- Download Cacheset.zip from my Downloads Page,
- Extract it somewhere on your computer,
- Run Cacheset.exe from where you extracted the file,
- Click on “Clear” button to clear the current working cache.
- Set the maximum working cache to either 64 MB or 128 MB,
- Click Apply.
- Buy me a coffee if this worked for you! (Link is in the sidebar)
I tried it and now, after one week of intensive tests, I didn’t get the Delayed Write Failed error! I suppose that the problem is solved.
Anyway, if it happens even after setting the cache, do the same process of cache setting (to 64 MB or 128 MB) again as Windows has tendency to go back to its initial configurations.
Note1: Test both the cases; 64 MB as cache and then 128 MB, if you get your disk working on 128 MB, so keep it, as it runs faster.
Note 2: When applying the “Working set maximum” value in Cacheset, calculate the number by multiplying the required cache by 1024. example: 64*1024=65536 which is the value you should give.
PLEASE GIVE FEEDBACK!
This is tested and it works! Digg it if useful.

Hi guys,
Just something else to try. I had this error with a new WD drive and tried everything to no avail. I then tried reformatting the drive as FAT 32 and it has so far seemed to fix the problem. Not sure why, but so far it’s worked.

O.K. I tried that program and it didn’t work so i need to try something else. I just looked on my external drive and I LOST ALL THE PROGRAMS! is there any thing i can do to get them back please help I lost about 2000$ worth of programs and i really need them.

@coolguy32: You need to run a checkdisk on the drive as said above! it will repair your disk in most cases.
Just plug it in and reboot your computer, windows might start a disk check automatically.
If not, you should use some disk checking utilities, like Norton Partition Magic or Paragon Disk Director Suit, or even you can find some free ones on the internet, or use the inbuilt “chkdisk” command from the windows command prompt.
I’ll be writing a detailed article on how to recover lost data from damaged hard drives, and especially ones with the Write Delayed Failed symptom.
Do not panic, you can recover all your programs, unless you’ve written new information on the drive!

Hi,
Can you explain in more detail what and where should information be inserted in cacheset?
When I run the application under “Adjust Cache Settings” I see two lines, one providing a minimum cache size and the other, maximum.
Should I provide the number (131072 or 65536) as a minimum, as a maximum, or as both?

@yudi: Thanks you! I’m really happy having you as a regular visitor!
@Ran: You should set this as the “maximum” value.

I have an old Dell OptiPlex GX150 which I recently installed Windows XP SP3 using a fresh install. I took out the 20GB Maxtor hard drive and installed a Seagate drive Model ST3250823A with 250 GB (IDE). My intention was to make it a file server. However, when copying large files such as AVI movies to it, I started getting “Delayed Write Failed” popup messages on the taskbar. The copies failed and no data was copied. I tried setting my cache as your article suggested. It worked. The delayed write failed messages are no more. I posted your article on JCXP.net website. However, when I download a large file to the hard drive which has the new settings, I get CRC errors on the files. The files are corrupt. BTW: I set my working set min to 65536 and max to 131072. Any ideas?

Looks like my problem may be IDE cable related. This is from the Seagate website:
-”Delayed write failure” error message, especially while trying to save a file or during heavy hard drive activity.
This error has several possible causes.
* Confirm that you have a 40-pin, 80-conductor UltraATA cable (available from in most of our retail kits or from most any computer store). It is easily identifiable by its multi-colored connectors, a blue connector for connecting to the motherboard, a grey connector for connecting to the slave drive, and a black connector for connecting to the master drive. See here for an illustrative graphic.
* If you do have such a cable, consider replacing the one you have. If the drive in question is the slave drive, connect the drive to the master position of the Secondary IDE channel cable (since your motherboard will have two of these cables). Before you do so, confirm that the Secondary cable is also an UltraATA cable. The CD or DVD drive might be connected as Secondary master by default; simply swap the drives’ connections for testing. You may use any power cable connection; the power cable is unimportant.
* Reboot your computer and watch carefully for the message “Press __ to enter Setup”. The key could be F1, F2, Del, Esc, or something else. Once in the BIOS, make sure that the Primary Slave (or Secondary Master, it depends on where your hard drive is connected) port is set to AUTO detect, or to ON.
* Test the drive with our Seatools diagnostic to see if it is damaged. Download Seatools here. See a tutorial to guide you in using it here.

Ok, problem is finally solved for me. I had an old cable designed for older technology hard drives. I put in a new 40-pin, 80-conductor UltraATA cable and now no more errors. Large file transfers are error free and FAST. I set my cache size down to default size. Check your IDE cable, if it connects to the motherboard with a black connector, then go get one with a blue connector. The connector to the master drive must be black and the connector to the secondary drive (if present) must be gray.

Hey
Just found this page. My new WD 500G passport just developed this DWF on my XP Pro Sp3 machine. It doesn’t do it on my other desktop, also a XP Pro Sp3 or my two laptops.
I’ve tried the Cacheset, but I am confused about the values.
After clearing and resetting the values, I now have:
min= 4572KB
max=65536KB
Is this correct?
I still have the DWF error message.
I haven’t lost anything off the drive, and I don’t get the message until I try to safely remove it.
Can you help me out, please?

Hey Guys,
Just a quick note to anyone having this issue and still using USB 1.1 as I was.
Before messing around with the registery, try upgrading to USB 2.0. You can buy a PCI card with 4 USB 2 ports for around $20… All my problems went away, not to mention the much faster copy times.
Hope this helps

Hey guys,
So since yesterday, I have been unable to open up my External Harddrive. Everytime I restart it, I have the autoplay come up and it appears under my computer, however, once it reaches the “My documents” part of my folder, it just continues search and search and search, and eventually, it disappears and the E:/ disappears from My Computer. So, I am unable to do a chkdisc. Occasionally, the Delayed WRite Failed message will come up with the $MFT message coming up on the bottom right hand corner of the screen. I tried to update the registry and fix the cacheset and still nothing.
Like I said, I’m not sure if I did these things right, but I’d like to get some help.

Hi,
I’m having the same problem as Andrew. I’m not really sure if this has got to do with a new audio equipment (some equalizer) I’ve got recently because I’ve just hooked it up to my computer just now and that’s when I’ve started getting these Delayed Write Failed errors. It may just be a coincidence, but whatever. I’ve got 3 internal drives – 2 of which have 250 GBs each for their capacities, and the other 500 GBs. I’m only having problems with the 500 GB drive (G:\) and I’ve looked all over Google trying to find a solution. I’ve yet to do an error-checking on it, but I’ll do so after rebooting my computer seen as the drive has completely disappeared off My Computer. Damn…I sure hope this would get sorted out – it’s all too sudden

Hi,
I have the same windows delayed write failure with a Western Digital 320 GB. But the problem only occurs when I pop in an extra USB stick (1gB). This ALWAYS happens. As soon as I connect the USB stick the “delayed write failure” occurs.
I’ve tried the cacheset and even the cacheman – but it seems to me I cannot have anymore drives. I’m on letter H:/. Can this be the case?
Gi do you have any idea or suggestions for solving the problem?
Would be grateful for any suggestions!

I’m have the same issue, I found if you put the drive on the ide cable inside the computer and boot it will run a chkdsk on it and you will have access to it again.

I have the Windows Write Delay failed problem with a My Book 500gb ES WD… i had the drive working properly for months until one day ( im not sure if i did or not install anything on windows…) it started popping up, it was really bad at the beggining like every time i’d hook it up i could barely access the any of the partitions before it went null and unaccesible… however i did a fat boot sector reload by switching the boot sectors to be read with this microsoft utility that comes in your windows cd… anyways, the drive was accesible again, the errors are alot less now, but randomly it decides to take a crap and go back to the write delay error…
the drive does have an external sata connection that i’m going to try soon…

in regards to this, none of them worked, i already posted on the 128k filter solution, and well
it seems to be that the drive is just overheating which just starts causing write delay errors. The drive is functional to about 35 degrees C,
since it has no internal fan, maybe the first few months would have been fine, but after a while of overheating the drive lifetime just drops and it seems to be my case… since i’ve opened the casing, and left it free to air it’s been working marvelously for over 3 hours now..

You wrote:”a fat boot sector reload by switching the boot sectors to be read with this microsoft utility that comes in your windows cd… anyways, the drive was accesible again, the errors are alot less now, but randomly it decides to take a crap and go back to the write delay error…”
What utility? How does one switch the boot sectors to be read? Can you point me to a web site for this? I’m trying like crazy to get my external USB drive back in order. It is ok on a new workstation, but then disappears from My Computer, Explorer, Dev.Mgr, Disk Mgmt, etc. Thx in advance for your help

Yeah, that’s why I have my 1TB Seagate HDD in my tower by itself and with good ventilation. Nothing kills HDDs like heat! Well dropping them while on, maybe…

well my problem was definitely heat. it’s been working fine for 4 days now working over 15 hours a day no problem.
