I had a client some 7 years ago that had SCSI controller X, it shot craps, and data couldn't be recovered from drives because the firmware on the RAID controller was likewise not available, used a "funky" algorithm, etc. (Novell was part of that problem IIRC.)
This is one of two reasons I recommend disabling any hardware compression, and using software compression instead.
Note that Dustin's account has nothing to do with hardware compression - which is reasonably consistent among different manufacturers of compatible tape drives. If the tape will mount on the drive, chances are the drive will read it, compression and all.
Software compression on the other hand, particularly if performed by a propietary program (say that three times fast), can be a guarantee of loss of data if you end up unable to run the origninal software version for some reason (lost or corrupted license key, customer support not available nights and weekends except at premium rates, etc.).
