When you insert a blank cassette in the Python drive for the first time,
it will be automatically formatted. The Python drive first detectes that
the tape is blank (about 10-12 seconds). It then formats the tape when it
receives the first WRITE command that stores more than 126 kilobytes of
data (total) or when it receives an ERASE command. The formatting operation
takes about 30 seconds.
If the first WRITE command stores less than 126 kilobytes of data, the data
is placed in the buffer until the next WRITE command exceeds the 126-kilobyte
buffer capacity and forces the stored data to actually be written to tape.
At the time the data is actually written to the tape, the Python drive
formats the tape before completing the operation.
So in a nutshell, don't worry about it.

I much prefer DAT tapes. A DAT tape drive is going to be my
next tape drive purchase.

1. DAT tapes vs. non-DAT tapes ( SCSI )
3. DAT TAPE DRIVES: Wangtek can't read HP DAT tapes
5. DAT tape drives, can DDS-2 write the old uncompressed format?
7. DAT recorder (formatting tapes, how?)
9. Reading Unix formatted DAT tapes in a WIN NT Machine
10. Reading ANSI formatted DAT tapes
11. so how do you format dat/dds tapes??
12. format.dat or "format" info for hp c2490a-300 disk
13. old DAT tape in new DAT drive ...
