I can also get both to work in 2.4.4 (and earlier 2.4.x) but only with what I believe is an unnecessay "workarround" - namely by configuring IDESCSI into the kernel (SCSI emulation) and then using boot param hdc=ide-scsi. However, I feel, that I should not have to do that with any kernel (that is, SCSI emulation should be optional for this device) because this was the case for 2.2.18. If I try not to use SCSI emulation for all 2.4.x kernels (including: Kernel 2.4.9-ac5 on i686 then ide-tape: ht0: I/O error, pc = 8, key = 5, asc = 2c, ascq = 0 tar: /dev/ht0: Cannot read: Input/output error (writes work OK though) As mentioned above, scsi emulation works for 2.4.4 (reads and writes). But if turned on in 2.4.9-ac5, then I get /dev/st0: No such device So, with kernels above 2.4.4, I can't use the drive at all (or at least can't "read" with it which makes it useless). The ideal situtation (at least for me) would be to have 2.4.x kernels behave like the 2.2.x ones, that is, scsi emulation would not need to be turned on for these ide drives (that is, it would be optional) and I would go back to using /dev/ht0.
