Hello
We have some 8 years old data cartridge on which data was written in
some format which nobody knows. Only thing we know that at that time we
had HP servers .Now we have only Alpha servers running Digital UNIX
V4.0C.

We already tried tar, restore, cpio, arch commands to read the contents
of tape and so far we are not successful. Every time it gives an error
"not a valid archive". But we are able to dump the contents of the tape
to disk using dd command #dd if=/dev/rmt0h of=a.a .I think the data we
get from this command is concatenation of data contained in all the
files of the tape

My question is
1,Is there any way by which I can restored the data safely and in proper
format
2Is there any way by which one can know by which command data is written
on the tape

Thanks
Regards
Vikram
