Correct. I cant remember ever having seen SCSI drives with block sizes
different from 512 bytes.
The software I use for copying tapes, is able to make block-to-block copies,
regardless of logical sizes. The only problem is that I have no TK drives.
Despite my involvement in media conversion since 1986 or so, I have sold
only one TK drive, and that one is in Norway. Cant even be sure about the
type. As it happens, I go to Norway this weekend for PM at that customer
(Tax Directorate), and I can check which one it is. What then could be a
possibility, is that I convert the tape next time I get there, which will be
around april 1 (no joke intended).
