Hi,

How do I delete single file from a tape drive?
mt -f /dev/st0 erase command will erase entire tape, i only want to delete single file from tape drive.

Thanks And Regards

depends on the tape systems design. in the 1960s, DECtapes were random access devices, or at least they pretended to be, so you could delete or insert in the middle.

I haven't see a tape drive in 20 years that did it. DAT, etc. don't do it.

Why would you need it?

And why are you using Tape? Most folks do backups to another hard drive, or a thumb drive if its small

I think I still have some old DECtape spools hanging around here somewhere...
