Posting here in the hope that some one may have encountered problems with recovery from backups on LTO4 media and found a solution.

Back ups on FujiFilm LTO4 media (800/1600).

Archives created using tar -cf /dev/nst0.  The tapes were fine when the archives were created (tested by extracting random sample files from them) but something went wrong in storage (no physical damage).

Now a few LTO4 tapes are giving I/O errors when I try to extract data from them.   Tried dd_rescue and that too fails giving  I/O errors.

I am wondering if there are any service providers, to extract the data out of the magnetic tapes in a fashion similar to "dead" hard disks.   Please share info if you know of any such provider.

norman ibas? it's a bit expensive operation of course ..
