** Description changed: I/O errors when trying to access IDE disk via an USB to IDE converter (sold as R-Driver II). Scanning with lsusb and lsscsi my system detects the device and a /dev/sda is created. However the disk partitions aren't seen and I can't mount it. A simple od </dev/sda fails with I/O errors, usually immediately but sometimes after reading a few disk blocks. - I also tried booting from a live 6.06 cd and I see the same errors. + I also tried booting from a live ubuntu 6.06 cd and slax (2.6.16 kernel) and I see the same errors. I've successfully accessed the same IDE disk via the converter on the same machine via windows XP and from knoppix (2.4 kernel) without issue.
