Windows Delayed Write Failed Error – Solutions
Window Delayed Write Failed ? Solutions are here!
This topic is researched, tested and written by Amir Hossein Moradi.
This is the third article on the Windows Delayed Write Failed error occurring with hard drives (mostly external ones with USB/Firewire/Network connections). On 28th December 2007, I wrote the Windows – Delayed Write Failed – Solved! article which had more than 190,000 views, and helped many users till date. On 9th June 2008, the second article on this topic – Windows Delayed Write Failed – Latest Solution – which had more than 34,000 views till date, was out and is still getting many users out of trouble.
Now, it’s time to write the 3rd article and sum up all possible solutions for the Windows Delayed Write Failed error.
About Delayed Write:
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).
About the error:
“Windows Delayed Write Failed” error occurs usually when the caching process gets interrupted or the files to be cached get corrupted, either because of a drive failure, a cable failure, or a USB interface fail!
This error might happen to brand new drives as well as good working old ones.
Cause:
This error might be caused by several factors:
- Cache settings
- System Restore settings
- Device drivers
- Media error, drive failure
- USB/Firewire host controllers
- Drive overheating
- Mis-configured BIOS settings
- Ultra Direct Memory Access (UDMA) mis-configuration
- Unmatched cables
- Faulty cables
- Memory parity conflict
- Power management drivers
On the next page(s) I’ll discuss all the working and possible solutions to this issue.

Hi Gio
I have the same problem as you did a year ago – one USB-HDD is not shown under System Restore (the other USB-HDD, that does not produce “delayed write failure..” is listed.)
I cannot see that you got an reply on the gibni.com page.
Did you resolve the problem? How?

My delayed write error on a WD secondary hard drive was solved by inserting a jumper in the HD to throttle back speed to SATA I

Can you please elaborate on you problem/solution?
I, too. have WD DATAs (500GB) as slaves and – after several years of flawless service – I just not got this nagging DWF message to appear.
I did have a power outage a week or so ago while I was on-line but didn’t see an immediate problem then after restarting.

Very informative and helpful. Thanks for sharing this. I’ve yet to observe after doing some of the solutions I’d done if the problem won’t come back again.

Solution #1 worked perfectly on my Seagate 1.0TB external drive. Thank you! It also solved a problem where my PC would always hang at the initial boot screen. I used to have to unplug the external drive in order to boot.
Great work!

i once came here and offered my thanx for the solution this guy offered here. he suggested a simple download ( which he had provided the link also) from sys internals…. i had read so many damn articles on this isssue that i was really getting tired, because non fixed my problem. I thought the solution that he put here was working. NO NO NO!
anyway, my dwf problem appeared suddenly and it became progressively worse. it would first start if i copied a picture from my computer to a flash drive. then the popups would get more frequent. i did everything i could: changing values from 0 to 1, or from 1 to 0; disabling write cacheing, updating drivers for usb controlers, etc, etc, etc. NOTHING WORKED! i read some more articles, all dead end.
I decided to reformat the damn hard drive and be done with it. well, it took me two days…many updates, service packs, applications, photoshop, Word 2007 and the even more updates and so on. HOWEVER, PAY ATTENTION TO THIS, when the computer started to copy the content from the factory cd onto the hard drive, three, four times a message popped up on the screen, saying the windows can’t copy such and such a file. they were mainly obscure names that i didn’t think much of. so i clicked on “proceed without the file”. BIG MISTAKE. after about two days of downloading the updates, service packs, etc, the computer was ok for two-three days, but then, BAM!, the delayed write came back. the same X:\$Mft. WTF!
I ran to fry’s in burbank and bought a new 320GB hard drive and started the whole damn thing. HOWEVER, PAY ATTENTION TO THIS, i didn’t get the messages that windows can’t copy such and such files, like the previous time. Anyway, installed everything, updates, service packs, photoshop, Word 2007, etc, and the computer has been working like a charm. NO PROBLEMS at all.
let me tell you something else, i ran chkdisk on the old drive a couple of times, and each time it reported that the disk was ok. WRONG! WRONG! WRONG! actually i think chkdisk is not a reliable tool. I had another failed hard drive on another machine that chekdisk reported it as clean and fine. so don’t trust it.
SO——> the problem was the hard disk and nothing else.

I installed max128K and do as instructed then my HD is working fine now but I have problem with USB port. It’s keep dropping off and on all the time. If I plug my mouse to USP port or hub, it’s drop off for a second then back on again. Also if I connect 2 HD (xternal) at same time, it kind of not read the 2nd HD or freeze it. Is there any solution to my problem? I’m using XP SP3. Thanks

@Nashii: well, if you’ve read the whole article, you should know that the USB port might be the actual problem. Just install another USB port (like a PCI extension card) and avoid using external USB hubs. connect your devices on different ports, on your computer, and do not use a usb hub with multi ports.
Re-read this article in full, with all the pages and if you got questions, get back to me.
Thanks.

And if it’s a laptop? What… am I suppose to connect a usb hub to one of my erroring usb ports?
It’s good of you to post info with helping others as your goal (if that is your goal). Just keep in mind if you will, that there are people who know the answers because that’s what they do for a living. Whether they’re electrical engineers, software programmers or pc support technicians, they don’t find their answers from reading countless bloggs on the net!
People… don’t be lemmings!!! Start with the manufacturer of the hardware that you are having issues with.
Good luck.
