Lost-Delayed Write Error

Here's the problem:
I am getting an error message "Lost Delayed-Write ... transferring from buffers" when attempting to copy large amounts of files to "DRIVE X" It is an external SCSI connected via Adaptec 2940UW.  There is only one other external drive connected. SCSI IDs are OK, Termination should be OK.  I've tried alternate cables. No internal devices are attached.

I've tried a clean install of Windows NT and Low Level format of all drives. Drives are formatted NTFS.

I'm guessing the drive is shot, but I seem to be able to copy some files over without a problem. Its a rather large drive for me (9GIG) so I would hate to toss it.

Any Ideas?

Length of the SCSI chain can be a factor, how long is your cable? The shorter the better, 3 feet should be good. Is this is your only SCSI device?  Try to use an "ACTIVE" terminator on the external drive, this will eliminate any possibility of termination problems.  Try resetting the AD2940 BIOS to DEFAULT settings.  The AD2940 is not conflicting with anything else is it?

Anything useful in the Event logs (eg SCSI timeouts)?  These errors can be caused by a mismatch in the volume size in NT and the physical disk.  Look in Disk Administrator, does the size listed under the disk match the size of the partition (assuming a single partition)?

Also make sure that you are using the aic78xx.sys driver from Service Pack 3 (Internal Name: BW0045a PV0145a v1.25c), this fixed a number of problems with the 2940's.

Event viewer has many of these:

The device, \device\harddisk2\partition1, has a bad block.

Error received is:
The system was attempting to transfer file data from buffers to \device\harddisk2\partition1\oth0126.pic. The write operation failed, and only some of the data may have been written to the file.

Error occured for many other files as well.

Latest SP is installed and correct driver.
Physical size and Partition match.
Only 1 partition on drive.

I've attempted to attach drive with different cables to another SCSI adapter (BusLogic Flashpoint) and still get the message. :|

I'd say the drive is bummed unless you can mark those sectors as "BAD" so the system does not access them.  But if the BAD BLOCK count continues to grow, then forget about using the drive.  It is definitely not reliable.

Acutally as a last resort, take the drive out of the external box and connect it up as an internal device.  That box maybe flakey which is causing the error.  Make sure termination is proper when pulled out of the box.

I tried a low level format from the Adaptec Card, it didn't work. I am tempted to think the drive is rubbish. Thanks for all the good ideas though.
