IBM Ultrastar U2W problems
Hi,
I am experiencing problems with IBM Ultrastar 9es u2w disk which is
supposed to allow 80MB/s transfer rate. I guess the problem has to do
with the parity (see the listing below), the drive appears to work fine
when I set in the SCSI BIOS max rate to 40MB/s. However, when I set the
speed to 80MB/s I get the errors. Does anyone have any luck making this
drive work at the highest rate?
I have Symbios 8951 adaptor that has 53c895 chip, the ncr53c8xx driver
is compiled into the 2.2.5 kernel. The system runs Debian 2.1 with the
upgrades needed for the 2.2.x kernels. BTW, is it OK the controller and
my AGP video card having the same IRQ?
Thank for any help,
