UPDATE 2: Latest article: Window Delayed Write Failed – Solutions –>
UPDATE 1: New post with new solution: Click Here
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 :
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…

Dear Sir,
I presently own a NOKIA N95-4 Model: N95 (A6.02), Type: RM-421. I purchased it approximately a month ago (October 2008) my product code is 0561948, while I was in the States. I have since then returned to Karachi, Pakistan. I updated my N95-4 software from V 1.2.001 to V 20.2.005, with the same product code mentioned above, with N series suite. However, my problem came when I found out that I no longer had my Arabic and Urdu fonts. I just need the Arabic & Urdu fonts that I previously had back in my device. What is your advice, The original product code still remains in my phone set I don’t want to mix N95-1, 2 or 3 product code with N95-4 device, unless it matches with N95-4 RM-421.
Please send your reply to {REMOVED BY ADMIN} or to {REMOVED BY ADMIN} , Anxiously awaiting your response and many thanks in advance.
Sincerely,
samir

@elizabeth baker: You can use the phone in ‘Data Transfer mode’ and find all your images and photos in the memory directly without syncing your messages and stuff!
@samir: As i’ve previously said in the comments above, you need to apply the right product code. For the language pack you’re looking for, the right product code would be : 0550805 .
Please let us know if everything worked fine for you.

@Gi: HI, but this product code does not have farsi and urdu language? and the version is 30.0.015 not 30.0.018. Have i missed something?

i have just bought a nokia n95 8gb but i do not find most of the functions. for instance, connectivity has only bluetooth and when i transfer data, it says “write file failed”. There is no way i connect to WLAN and though i have installed the n-series PC suite, the connectivity cable is not working. Could it be because i have service pack and what about the other problems?

@mymoona: Hi, this issue has happened to other visitors as well. I would recommend that you take a backup from your phone and hard reset it as explained in: http://www.gibni.com/n95-wont-boot
