- Make sure you set the block size for 8mm to 1024! Otherwise, you are
- wasting 1/2 of each helical tape track. This would also (most likely)
- affect transfer rate, as the system has to wait for the track-padding
- to occur before writing more data for the next track. I've posted a
- relatively descriptive article about how 8mm works in the past, so if
- you need more information search through past articles....
-
- "mksysb" needs a 512 byte block for a different reason, and you must
- manually set the block size back to 1024 after you do an "mksysb".
- This is also described in a past article.
-
- Hope this helps!
