This is what happened...

I had a hard drive setup with NT 4 Server and Oracle 8.05 server. I also had Backup exec 8.5 installed with support for Oracle. The database I had did NOT have archive log mode on. 11 days went by without doing a warm or cold backup

I backed up the entire hard drive to tape using backup exec. installed a RAID controller card and an additional hardrive which required the format of both hard drives.

I then reinstalled nt 4 server and oracle 8.05 server but cannot recover any data because I don't have a warm or cold backup.

Is there a way that this can be done? or is all lost...
