Code:
empeg:/drive0/var# ./hdparm.bin -W1 -K1 /dev/hda

/dev/hda:
 setting drive keep features to 1 (on)
 setting drive write-caching to 1 (on)
 write-caching =  1 (on)


Just uploaded some files and got:

Code:
hda: stat_timo: status=0xd0
show_message("0000.-1 hda: err: stat_timo")
hda: no DRQ after issuing WRITE
ide0: reset: success
hda: stat_timo: status=0xd0
show_message("0000.-1 hda: err: stat_timo")
hda: no DRQ after issuing WRITE
ide0: reset: success
hda: stat_timo: status=0xd0
show_message("0000.-1 hda: err: stat_timo")
hda: no DRQ after issuing WRITE
ide0: reset: success
hda: stat_timo: status=0xd0
show_message("0000.-1 hda: err: stat_timo")
