I'm trying to read data from a Sony AIT-e260 SCSI drive under Cygwin. Cygwin 1.5.21-2 mt 2.3.1
I know that the tape is good, because I can read from it (using the same drive) under Redhat. The first file on the tape is 96 bytes so I do the following: >> export TAPE=/dev/nst0 >> mt setblk 0 >> dd if=$TAPE of=header.txt This works fine. The second file on the tape is 1GB and is written with a block size on 200kB. When I do the following: >> mt setblk 204800 >> dd if=$TAPE of=segment.0 I get the following error: mt: /dev/nst0: Invalid argument I've found that the maximum block size in mt can only be 64kB. Am I missing something or is there a limitation to mt under Cygwin? If I leave the block size set to variable, I get the following: >> mt setblk 0 >> dd if=$TAPE bs=204800 of=segment.0 dd: reading `/dev/nst0': Cannot allocate memory 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.078 seconds, 0.0 kB/s Just for kicks, the tape drive status before any dd is: drive type = 8mm Sony AIT1 tape drive status = 838860800 sense key error = 0 residue count = 0 file number = 1 block number = 0 Tape block size 0 bytes. Density code 32 (ALRF-2 (SLR 7)).
