I agree with Tom about LTFS reliability..but it just happened and I’ve big problem because I worked on the open source HP software on LTFS and right now I received last message from HP support that they don’t see any bugs and problems from their hardware or software and support application was closed.

I checked these tapes on the Cashe-A hardware and software, but without any positive results. Copying crashes on this same files in this same moment. I know that we have to change our workflow, but I would like to recover all these ‘crashed’ files.
Do you know any software for deep recovery for LTO-6 on Windows or Linux (our SAS controller is not compatible with OS X). I checked ltfsck, but result was that media are consistency and it didn’t solve problem.
Or maybe some software which, can dump all files from tape, without indexing?

Sorry for spam, but I have to restore all this file as soon as it possible. HP support don’t have any idea how to fix this problem. The strangest thing is that after archiving files, I checked md5 file on tape and it ended correctly without any errors. Now, after few months with no using this tape, device can’t find crashes files and checksums show errors on them.
Any solutions how to fix this problem? I know that I should change workflow and buy some dedicated software like BRU, but for now I need to restore all this files in a few days..

Cheers

I sort files before copying and restoring many files don’t take so much time to copy from LTO to server, until it runs into one file, where it crashes and zig zag all over the tape searching this one frame. It can takes many hours without any result.
