Thanks.

------- Comment #12 from [email protected] 2008-04-16 00:43 -------
I can only rely on previous data as my company after seeing 400GBs lost
decided to switch to w2k3. I managed to save one of the copies of the bad tape. I gave it to some IBM guys in Scotland and they confirmed that there is an EOD on the tape, but they could not rewrite it. Normal LTO specs forbids doing anything beyond it. I would need a hacked LTO firmware to be able to overwrite the EOD. From there I could raw read the tape and recover the data.

Right now the case seems hopeless though.

Nobody has reported a similar problem. I can't reproduce it. The reporter's company has switched to another operating system. I think this problem will remain unsolved.

------- Comment #14 from [email protected] 2008-04-16 10:51 ------- Fair enough. Closing as unreproducible.
