Description Ulrich Derenthal 2005-09-18 15:29:10 UTC 
When I try to set the IDE DMA mode of my brand new 250 GB Hitachi
HDS722525VLAT80 to UltraDMA/100, only DMA modes up to UltraDMA/33 are listed.

However, with the 160 GB model HDS722516VLAT80 of the same series, all modes up
to UltraDMA/100 are listed. Furthermore, the commands
cat /proc/ide/ide0/hda/settings
and
cat /proc/ide/ide1/hdc/settings
list "70" as "max" for "current_speed" for both harddisks, which seems to
specify the DMA mode, and UltraDMA/100 should correspond to 69, so it should be
supported for both.

When I specify
/dev/hda:udma5 /dev/hdc:udma5 
as
DEVICES_FORCE_IDE_DMA
both harddisks are set to UltraDMA/100 correctly.

Why doesn't the IDE DMA module let me select UltraDMA/100 in the first place?
Comment 1 Ladislav Slezák 2005-09-19 15:09:25 UTC 
The yast module detects possible values using 'hdparm -i <device>' command.

Please, attach output of the command for the disks.
Comment 2 Ulrich Derenthal 2005-09-19 19:28:10 UTC 
hdparm does not give UDMA 5 for the 250 GB disk. No mode is marked as active
probably because I have "/dev/hda:udma5 /dev/hdc:udma5" as "DEVICES_FORCE_IDE_DMA".

Output:

/sbin/hdparm -i /dev/hdc

Comment 3 Ladislav Slezák 2005-09-20 13:59:47 UTC 
Hdparm reports UDMA33 as the fastest mode. The problem may be in the hdparm
utility, kernel or in the disk itself.

Reassigned to hdparm maintainer
Comment 4 Ruediger Oertel 2005-09-20 16:21:53 UTC 
"hdparm maintainer" that does not really know too much about the 
internals ... expanding CC list. 
 
Jens: can you help ?
Comment 5 Jens Axboe 2005-09-21 08:38:36 UTC 
Please try hdparm -I
Comment 6 Ulrich Derenthal 2005-09-21 18:26:12 UTC 
To me, it looks like they both report udma5.

OK, so the yast module should use -I switch ...
