Sun Managers,
Thanks for all of the quick responses!
The question:
I have an HP C5653A SurStore DAT24eU external tape drive attached to a
SPARCstation 5 running Solaris-2.7. I had a tape filled with files
containing data. Then, accidentally I wrote a file at the beginning of
the tape. My thought is that if I could get past this file, I could get
into the remaining good files and do some recovery. The problem is that
I can't seem to get past this initial file. I tried the mt command to
skip past filemarks and I tried a program usind open/read/ioctl to read
records and skip filemarks. I always end up with an "I/O error" and it
will not go any further than the first file. Are the any ways to get
around this problem?
The general consensus:
Send the tape to a data recovery company.
The limitation is in the drive. Commercial drive units always write an
EOT mark at the end of a write (later writes will erase that one and
write another one). You cannot command a commercial unit to forward
past the end of that EOT. (Darren Dunham)
A few suggested things like mt, GNU tar, cat /dev/rmt0, dd if=/dev/rmt0. But
the problem is still that I cannot get past the EOT.
Thanks to:
