Short Erase

Post by tommyo » Aug 27, 2019 3:48 pm

I understand that Short Erase doesn't erase data on the tape, only the header. My question is can data be restored from a tape that has gone through the Short Erase process but has not been overwritten with new data? I'm wondering about how much damage could be done by a malicious user who had access to the console and tapes were still loaded in the library. Long Erase I'm not worried about, it takes to long erase a LTO8 tape with Long Erase.

Thanks,

Tom

Hello!

No, restore is not possible after short erase. This option speeds up erase process but is not supported by some tape devices. Thanks!
