Pertec Tape Drive Interface Musings

[Chuck Guzis]

Another issue with SCSI tape interfaces are in the details.  Al has 
pointed out the lack of data returned with error conditions.  There are 
also niggling little differences between implementations that don't 
exactly follow ANSI X3T10.  For example, is a tape mark considered a 
block? I've got drives that go both ways--one says it isn't and so 
doesn't increment the position (I'd call that an error) and other says 
it is.

It's mostly the problem of adding another layer of someone's 
interpretation to another older protocol and hoping for something 
coherent to come out.
