There is a problem with ide-scsi in 2.6, and rather than fix it someone came up with a patch to cdrecord to allow that application to work properly, and perhaps "better" in some way. Since the problem with ide-scsi seems to still exist for other applications, you will probably find you have to work around the problem, by using the -pad option of cdrecord (thought that was standard now for TAO at least) or reading using the ide-cd driver. I don't remember what the issue was for using ZIP drives with ide-scsi, other than that using the alternate driver didn't do something right. That might be fixed, I just went back to 2.4 on my machine which needs that. The problem using ide tapes was that you needed ide-scsi to make 'mt' work, there's no patch for that AFAIK, and tape operations work without kernel errors, but the data read back didn't have the same md5 as the data written out. My one IDE tape drive is on the same box as the ZIP, both seem to work fine with ide-scsi under 2.4. I only use those devices for exchange with a few clients, so spending time on the problem wasn't and isn't justified. Hope this helps you define your problem more clearly. -- bill davidsen CTO, TMR Associates, Inc Doing interesting things with little computers since 1979.
