hdparm shows identical values on Ubunutu and Knoppix, except for
queue_depth (values 31 vs. 1), but changing the value under Ubuntu had no
noticeable effect.

ubuntu$ sudo hdparm -acdgkmurABCMNQW /dev/sda

/dev/sda:
 multcount     = 16 (on)
 IO_support    =  1 (32-bit)
 readonly      =  0 (off)
 readahead     = 256 (on)
 geometry      = 364801/255/63, sectors = 5860533168, start = 0
 look-ahead    =  1 (on)
 APM_level      = not supported
 drive state is:  active/idle
 acoustic      = not supported
 max sectors   = 5860533168/5860533168, HPA is disabled
 queue_depth   = 31
 write-caching =  1 (on)

Any other ideas?
