Slip of the brain... 8mm Exabyte, of course.
Interestingly enough, I never had much trouble at all with the 4mm drives.
Go figure. Haven't used any of the rotary head drives much since getting
my first DLT in 2005 or so.

We violently agree on that point... I used DLT7000 drives for a few years
until I grew tired of changing tapes every 1/2 hour. Currently quite
happy with the LTO-2 units. The eBay price-point is just right and I was
able to pickup a plastic storage-bin full of tapes for $20 at a flea
market. The tapes track usage and none of them were anywhere near the
point where I'd worry about data integrity.
