160gb maxtor with promise ultra 100
hi,
recently i installed two 160gb maxtor drives. using the latest ac-kernel (.19-pre2-ac3), they were detected correctly. however, the promise ultra 100 (detected as pdc 20267) hangs at the partition check. last thing it prints is "hde:" and it's dead. however, if i connect the drives to the onboard piix3 ide, they are detected correctly, survive the partition check, and _do_ work as 160gb drives, but slow (piix3 only supports mdma2, no udma). if i boot the latest non-ac-kernel available on the machine (which is the not so recent 2.4.14) the drives are misdetected as only 137gb (of course, no 48 bit support) but otherwise the machine works, even with the drives connected to the promise.
so the situation is - either i use the full 160 gb, but only mdma2 data transfer. or i use udma 100, but only 137 gb of the drives. i can't seem to have both.
i am out of ideas what might be causing this. of course i could just throw the promise out and leave the drives connected to the on board controller, but... other ideas?
tia,

Seems to be the case. Promise posted some driver updates today, which in part appear to address precisely this issue. It just needs the IDE update and the promise code merging then hopefully it can be in for 2.4.19

I had something similar - with 2.4.17+ide patch and PDC20265. The kernel hanged at exactly the same position. I moved the disk to hdg (master on second channel, instead of first), and it works OK.

Check promise's website for a bios update for the controller. the earlier versions of the ultra100 don't have 48 bit lba support, if i recall correctly.

Neither does the latest I know of (2.01 Build 27). This shouldn't be the problem, though, since the machine boots from SCSI. The Maxtor drives are just cheap data storage. I also think that the linux driver does not use the BIOS at all, just the hardware.
Well, let's hope for 2.4.19. Will use the onboard IDE for the time being.

Thanks for the hint, but this is not really an option for me. Both drives should be master on their own channel. I would have tried with both drives on the secondary channel, unfortunately the cable is too short for that configuration. It would barely work for the primary, but then I still have the hde: problem.
