upto now no transfer to the drives, except to the root partition(system
activity) which is on hdg

dd if=/dev/zero of=/mnt/tmp/1/10Gb.zeros bs=512k count=20000
[/dev/hde]

ide_dmaq_intr: hde: error status ff

hde: ide_intr: huh? expected NULL handler on exit
hde: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hde: drive_cmd: error=0x04 { DriveStatusError }

and a bit later

ide_dmaq_intr: hda: error status ff
hda: ide_dmaq_complete: status=0xff { Busy }
hda: invalidating tag queue (1 commands)
hda: ide_intr: huh? expected NULL handler on exit
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }

only /boot ~ 90Mb was mounted on hda and i don't think the system accessed
it

on second thoght i also have a swap partition on it,
but i have currently 1.9Mb swap used
