Actually, while this subject is being brought up, if I don't do: /sbin/hdparm -d0 /dev/hdc on bootup, my system locks up randomly. Looks like a DMA issue with my hdc drive.. Details are:
/proc/ide/hdc/model: QUANTUM FIREBALLlct08 26
This seems to confirm my doubts about Quantum lct drives' sanity. I'm having two drives: a Quantum CX 13G, and a Maxtor 40G@5400. Both work with UDMA33 (mb doesn't support more). When i put a QUANTUM FIREBALL lct20 20G drive in my rack, random lockups occur. I'd put all Quantum LCT drives on the blacklist!
My Quantum Fireball lct20 works fine, and i work in UDMA 5, without any problems...
Ok, i have a problem, in Ultra 5 i can't got same performance of other (no cheap) HDs...
$ hdparm -i /dev/hda
/dev/hda:
