in Linux, you can configure your tape drive to accept variable block size with "mt setblk 0". without a variable block size, I have found that you need to set minimum and maximum block size to the same value, or else Bacula may write an, e.g., 66 KiB block if you have configured minimum block size to be 64 KiB. at least my LTO-5 drives will not accept a 66 KiB write after "mt setblk 65536". oh, and I'm using max block size of 512 KiB, since that is what HP's own tape testing tool (hp_ltt) is using. -- Kjetil T.
