Thanks Todd,

For this useful information. Sure I will contact PSS.
I know about Transaction log files. I read it all ablut in KB.
Will you provide me some linkes to get more info about the role these logs
play in .edb file or with database and how information is saved into .edb
files.

Thanks again

Regards
Guri

You really should try to find the hardware issue first as it will most
likely corrupt
your database again. I would also open a case with PSS as they can assist
you better
than the newsgroups.
