I am unsure why my tape is half the speed but almost 40 gigs more than the
others in the Amanda Wiki. My tapes are Imation Ultrium LTO 3 tapes. Maybe
they are a little longer?
Amtapetype was executred with the device /dev/st0, I do not think this
would make a difference, or can it? Also SCSI generic support was not
available at the time.
Now that I have everything from the barcode reader working to the tapes
labeled, I will run the tapetype again. I also have SCSI generic enabled
and plan to run tapetype with the /dev/nst0 device.
I will cut and paste the complete console message after the job is
complete if it comes out different. I will use the same tape that I used
to run the original tapetype too.
After all, I too am wondering why I got more space but half the speed. I'd
rather have the reverse.
