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?
