 Posted: Tue Jan 16, 2007 8:31 pm Post subject: SCSI drives lost since new motherboard |
 |
|
Hi all,
Recently I installed a new motherboard (ASUA P5B) with processor and memory.
I Kept my old SCSI card (Adaptec 7850). The system runs fine, but I can see
no SCSI drives. To the card there are internally connected a SCSI CDROM and
a SCSI CD burner. Externally connected are a flatbed scanner and a film
scanner. Both scanners work fine, but the drives are invisible. Windows
can't see them. In the Device Manager the SCSI controller is listed. The
Disk Manager can't see the drives, however. I assume there may be an
interference with the F6 SATA driver, but it's just a guess. And I need that
driver as it is necessary to use the SATA discs.
Does anybody has an idea?
Many thanks in advance.
With kind regards,
Fokke Nauta |

When I loaded Linux onto my machine, which unfortunately came with a |
SATA disk (to which I had added a SCSI disk, with Adaptec 29160),
The SATA disk is seen as a SCSI disk (presumably with a motherboard
controller?) and the true SCSI disk is picked up by the 29160 HBA.
I know SATA is crap, because CPU usage goes way up when I use it (for
backups and to store my mp3's on).

That got my attention because I'm about to start using SATA drives.
Is DMA enabled, or is it not yet supported by the hardware? drivers?

Hi Jeremy,
Good that you mention this. I have just purchased 2 large SATA drives as the
new motherboard has only 1 IDE port and is further fully packed with SATA
ports. So - for me it's too late but I will keep an eye on this.
All of a sudden, after 2 days, the drives have been detected. Surprisingly.
So my problem has been solved but I don't know how.
Thanks for your response.
With regards,
Fokke Nauta |

I think so - dmesg says:
ata2: SATA max UDMA/133 cmd ox970 ctl 0xB72 bmdma 0xD808 irq 217 for the
partition.
I copied a 695 Mbyte file to the same directory on the 7200 rpm SATA
drive.
I have a dual core PC;
cpu1 had a utilization of about 40% for the duration of the copy,
cpu2 had a utilization of about 4% - there was not much else running.
I placed a copy of the same file on my SCSI drive (10000 rpm) and I got
results of about 15% and 5%
This was not a good test as a sequential copy like this should give
better results with high-density SATA and IDE drives over lower density
SCSI.
