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.

I must say I’m impressed by the length and detail of this website. Unfortunately I still haven’t cured my USB write errors.
My system is a 2GHz Celeron, 512MB RAM, WinXP SP3. I have a Maxtor series 6 drive in a USB case. Copying moderately small files (600MB or so) from the PC to the USB drive produces DWF errors.
The USB case has its own PS, it’s not a power issue. I’ve switched USB cables. I’ve tried front and back USB ports on the PC. (The enclosure’s HD cable is fixed, not changeable.)
In Control Panel, I’ve turned off cacheing on all my hard drives. I’ve turned off System Restore on all drives. I can’t find any UDMA settings in BIOS; besides BIOS only has settings for the PC’s native drives, right?
In regedit, I confirmed that Large System Cache is zero. Per the microsoft knowledge base, I set SystemPages to a couple of larger values, without success. I tried Max128k but it didn’t help on my system.
I tried Cacheset, and for a while it looked as if the file was copying, but then I got a “path too deep” error! That makes no sense, because the file was in the root of both the source and destination drive, and the filename is 24 characters including the extension.
Short of using a 3-pound hand maul, is there anything else I can try?
THANKS IN ADVANCE!

Apparently there are several things that can trigger this error, all w/different solutions.
Similar situation here, but on a networked system.
Tech changed a setting on the network card, and that solved the issue.
Good luck.
