If you have stepped down to U-DMA mode 0 and you are still getting excessive ICRC errors then maybe it is time to "blue screen" and tell the human to fix their hardware. Under no conditions would I recommend stepping down even more to MW DMA or any PIO in this case. Just how many undetected data corruption errors can your OS or application programs live with??? *** Hale Landis *** [EMAIL PROTECTED] *** *** Niwot, CO USA *** www.ata-atapi.com *** Subscribe/Unsubscribe instructions can be found at www.t13.org.
