SCSI delayed write error

SCSI delayed write error

One of my SCSI drives keeps saying it has a delayed write failure. I have a four disk striped set, disk 0 seems to always fail. I downloaded seatools and the disk passes the short test sequentally and individually. I am going to change the SCSI twisted cable and try again. The drives are all hot swap 80 pin drive with 68 pin adapters on them. After I re-activate the drive it will work for 5-10 min then fail locking up my toaster. Some times the toaster will say unable to write to cache.

If anyone has had the same problem or knows a solution let me know.

Thanks!!!

Found this article in the Windows XP Knowlege Base!


I dissabled the write caching on all the disks in the stripe set as stated in the article below and I no longer get the error but is this the best settting for toaster? And am I loosing performance?

"Delayed Write Failed" Error Message When You Manage Files in Windows XP
The information in this article applies to:
Microsoft Windows XP Professional
Microsoft Windows XP Home Edition

This article was previously published under Q330174
SYMPTOMS
When you save or move documents or during general file-management activities in Windows XP, you may intermittently receive "Delayed Write Failed" error messages.

CAUSE

This issue may be caused if any of the following conditions exist:
The "Enable write caching on the disk" feature for your disk is turned on.
Your Ultra Direct Memory Access (UDMA) hard disk controller is configured in either of the following ways:
You are using a 40-wire connector cable to connect the UDMA drive to the controller instead of the required 80-wire, 40-pin cable.
Your BIOS settings are configured to force faster UDMA modes.

RESOLUTION

To resolve this issue:
Make sure that your UDMA hard disk controller is using an 80-wire, 40-pin cable. For information about how to do so, view the documentation that is included with your computer, or contact your UDMA hard disk controller manufacturer. Test to determine if the issue is resolved. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to the next step.
Warning Do not change your BIOS settings unless you are very familiar with all the effects of changing BIOS settings.

Make sure that your BIOS settings are not configured to force faster UDMA modes. For information about how to do so, view the documentation that is included with your computer, or contact your computer manufacturer. Test to determine if the issue is resolved. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to the next step.
Turn off the "Enable write caching on the disk" feature:

Note If you turn off the "Enable write caching on the disk" feature, your disk performance may decrease. Because of this, you may want to monitor system performance after you complete the following procedure.
In Windows Explorer, right-click your hard-disk, and then click Properties.
Click the Hardware tab.
Click the hard disk, and then click Properties.
Click the Policies tab.
Click to clear the Enable write caching on the disk check box, and then click OK two times.
Repeat steps c-e for each hard disk that is installed in your computer.
MORE INFORMATION
When you start your computer, the BIOS checks the system-specific settings that are stored in the complementary metal-oxide semiconductor (CMOS) chip. You can modify these settings as your computer or your needs change.

What is the SCSI controller card you're using?

Try to update the firmware of the controller if available. Make sure you have the latest Windows XP Pro Service Pack 1a installed.

I haved a P4DC6+ sumermicro motherboard with onboard SCSI 160 controlers. I am going to change the SCSI cable and get new 80 pin to 68 pin adapters but that is my absolute last effort. My system has 2 used seagate 78 gig ST173404LCV drive, 1 used Seagate 78 gig ST173404LC drive, and 1 used Seagate 78 gig ST373405LC drive. Dose the following apply to me are my drives compatible?


Seagate’s high-performance Cheetah and Barracuda Ultra2 and Ultra3 LVD drives (drive models with a suffix of LC, LCV, LW or LWV) are ushering in the future by utilizing the super-fast Ultra2 and Ultra3 SCSI parallel interface capabilities. Users of video, database servers, RAIDs, workstations and high-end desktop applications benefit from the greater I/O bandwidth, device connectivity, data reliability, and longer cable lengths offered by LVD. With the capability to multi-mode, Seagate Ultra3 and Ultra2 LVD drives are backward compatible with single-ended Narrow and Wide SCSI devices, but not High Voltage Differential (HVD), and provide cost savings, rapid bus rates and increased reliability.



I am tempted to give up and get a G5 Turnkey system, I put moore time in fixing Toaster errors then actually editing. I am loosing my creative drive. I have gone from a mediocure editor to a half witt technican. From system configuration problems to software issues. I CAN'T GET THIS DAM THING TO WORK .

I think I have got it narrowed down to a hard drive issue. Before I had dual xeons I had dual Athlons with boot issues and campadibility problems. Now my xeon system is srewed it keeps giving me harddrive probems as stated above. I could have been more productive cutting and splicing 2 inch Umatic tape.

Ok, Just had to get it out of my system. I'm gonna call Newtek directly on Monday moring. I would just get a whole new set of external scsi drives but it is out of my price range right now.
