After the 'extract', it asked me for the correct tape which I loaded and then it skipped through till it reached the correct tape file and started restoring it. tar then complained of an invalid header and said it was skipping to the next file. Next, on the server, I tried an amrestore to local disk. It died saying the compressed file was in the wrong format. It had however restored about 150Mb of the file (not enough for the bit I needed). I then tried several other files from the tape and got similiar results. Next I used dd to copy the file from the tape to disk and then tried to gunzip it. Boom... bad format. It seems that all of the files, as written to tape have been corrupted somehow. I wonder whether I have a scenario where the compressed tar is being compressed by the HW ( I have not explicitly turned H/W compression off or on, maybe the default on an 8505 is on! If so, how do I turn it off ? ) I have given up being able to recover anything written to date, but I really need to ensure that anything more written can be recovered from. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen and Rosanne Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.
