I have trouble using an Exabyte 8200 with the FreeBSD SCSI drivers.
I have tried them using two different Exabyte drives on Adaptec
2940 (PCI), Adpatec 1740A (EISA), Adaptec 1542B (ISA), BusLogic 747s
(EISA).  

When using tar to backup large amounts of data (>1Gb) I often get 
media errors.  Many times everything will work OK, but every now and
then I have problems.  Media errors are errors that are common with 
tape drives and most drivers will back up and re-write the data several 
times.   Old 9-tracks tape drivers would eventually backup and erase 
over tape media flaws and then re-write the data block.

These same drives work fine using the same tapes when they are hooked 
up to a Sun 3/60.
