Both quick and advanced test returned that the drive is ok. I then ran the = test against ad0 (the backup drive): the quick test showed that the drive was defective because of "Excessive Shock". Re-executing the test gave same res= ult. I rebooted the system and disabled the S.M.A.R.T. option for the drive atta= ched to the motherboard's controller (i.e. the backup drive). Re-executing the q= uick test showed that the drive is ok! After 16 hours of uptime and one level-0 file system dump all drives are st= ill using UDMA100. If for some reason the system will fall back again to PIO4 mode I will try = to remove the two following options from the kernel: # ISA optimization options AUTO_EOI_1 options AUTO_EOI_2 If the problem won't still be solved then I will try in order the following: - disable tagged queuing - buy different hardware!
