it not only can. it SHOULD.

first install IDE patch from hedrick. then do hdparm -u 1 -a 0 -A 1 -W
1. should be enough
> 3) If 1 is yes, can it be used on IDE and SCSI disks, or only in one of them ?
on both. on SCSI only -a 0 make sense.
for SCSI use scsiinfo tools to enable write caching on drive if it's not
