Looks like i have a big problem to solve. I have a scsi card
Buslogic BT-542 and i am encountering severe problems with it.
On this card, there are three devices plugged: two hard disks and a
cdrom R/W Ricoh 2600S. All those things on a 486DX/2 66.
In order to try my cdrom player, i have tried to dump an audio track
from the cdrom to the hardrive. I have tried cdda2wav.
So, really self confident, i have typed :
nice -20 cdda2wav -c 2 -s -b 16 -r 44100 -t 1 -D /dev/sgc \
-I generic_scsi -v out.wav
(i have also tried readcdda, but it s the same)
All this to dump track 1 on the disk. Dump goes ok, but the resulting
file is unusable, the sound is shaky as if there was a I/O problem.
Effectively, hdparm -Tt /dev/sdb gives me:
bash-2.01# hdparm -Tt /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 32 MB in 4.31 seconds = 7.42 MB/sec
Timing buffered disk reads: 16 MB in 11.19 seconds = 1.43 MB/sec
Which isn't really much !
I suspect there may be a problem with the card. But is there a way to
solve that ? Are there any tools i could use to monitor and why not
a tool to optimize the transfert rate of it ?
OR maybe it s something completely different, i am really lost.
Any idea ?
Andre
PS : i am enclosing two files : first one is the content of
/proc/scsi/buslogic and the second contains what's about scsi devices
in the dmesg.
