| Re: [PLUG] Old IDE drive on USB enclosure with Linux |
So I tried several live gparted CD's I have to see what happens. Here I am connnecting the drive (old 1994 425MB disk) with an ide cable to an ide controller on an old machine (no enclosure involved). Gparted 0.3 (kernel 2.6.17 was fine with with the disk, showing it as /dev/hdb. I could mount partitions from a terminal Gparted 0.7.1 (kernel 2.6.32) had issues (showing as /dev/sdb) (though it still managed to show me the partitions, but reported issues with dealing with the disk). Also I could not mount the partitions from a terminal window. I noticed during the boot and tons of repeating error messages too fast to read, after a scroll lock, and missing many many messages. Saw the following message after it moved on and decided to continue booting. ide_generic: please use "probe_mask=03xf" module parameter for probing all legacy ISA IDE ports. So I tried removing the module ide_generic (shown as permanent), but had to do a "force" removal of it. I tried to put it back with "modprobe ide_generic probe_mask=03xf" but it reported errors and would not load (modprobe ide_generic loads OK). Did I specify that parameter right in modprobe? Or maybe this is a boot thing that has to happen at boot time? Off to google again and I found this: http://www.gossamer-threads.com/lists/linux/kernel/957931 So I reboot, and say "ide_generic.probe_mask=0x3f" as a boot parameter as shown in the web page. Now gparted 0.7.1 (kernel 2.6.32) no longer reports any issues with the disk, and I can even mount the partitions on a terminal. It works with 2.6.32 using the parameter modification. With Kubuntu (2.6.28) it does not like the boot parameter "ide_generic.probe_mask=0x3f" and there does not seem to be an ide_generic module available. So why are these drives no longer supported automatically (in whatever state I currently have it in)? (though I can't say what the difference is yet with newer ide drives.). Something seems to have changed when all devices started going to /dev/sdb*. At least I think I am converging in that time frame. -- Now can I relate this discovery to the driver for the enclosure box in some way to make that work? And what could I specify in Kubuntu to have it happy with this drive? (not sure if that question is worth investigating or not).
