"delayed write failed" with firewire external drive

[doug]

Wondering if anyone here can help with this.

When attempting to use my ByteCC ME-350U2F external drive case with an IEEE 1394 (Firewire) connection I get the following error when I try to copy
files to it: delayed write failed
File copies failed with files from 76KB to 460MB.

It works find if I use the USB 1.1 connection on the same machine.

Machine specifications:
Windows 2000 SP4 running on IBM Thinkpad A31P
Laptop with built in IEEE 1394 and USB 1.1
ATI MOBILITY FIRE GL 7800 built in graphics card

Eject unplug device lists:
Prolific PL3507 Combo Device (1394 ATAPI_Rev 1.00) IEEE 1394 SBP2 Device

Disk was formatted using win98 startup disk on a different machine, directly connected to IDE controller (not in external case). fdisk a primary DOS partition as whole drive. Formatted as fat32 (want o share with a win98 machine).
Maxtor DiamondMax Plus 9 160GB ATA/133


Using 1394test.exe from http://www.bustrace.com/products/delayedwrite.htm
the test failed with:

Other people appear to have had luck setting their UDMA from 6 down to 5 or even as far as 2 but unfortunately that requires a utility such as the Oxford firmware uploader to change the settings, ByteCC doesn't have one available for the Prolific chipset and Prolific doesn't talk to end users http://www.prolific.com.tw http://tech.prolific.com.tw .

I tried setting the following registry entry, no effect.

original setting 0x0006300

I bought an enclosure from Compusa that uses the prolific pl3507. It supports firewire and usb 2.0. When using the firewire I too get write delay errors. At first I thought it was my firewire adaptor, I am using my sb audigy's firewire. However, I am also using a sonly laptop with a TI firewire chipset. I am getting the error on both systems. I can not find any firmware or driver updates for the enclosure.

Any ideas? I am thinking I might just take the enclosure back to Compusa. Any recommendations on alternative enclosures? Ideally I would like both firewire and usb 2.0.

Thanks for the help.

I got that Write Delay error on my secondary hard drive 1 day before it completely died on me taking all my data with it.. You might backup anything on it ASAP if you haven't already

Well here is the thing, I tested the drive today using the USB 2.0 interface and it worked flawlessly. I believe the problem lies with the firewire bridge and/or its driver. I even recieved an e-mail from the company that they are aware of the problem and that they recommend lowering the UDMA setting. Only thing is though how do you lower the UDMA setting on a drive in an external enclosure? Thanks for the reply.
