HI all. Long time Amiga owner.

Back in the day (1996) I made a DAT (DDS1) backup of my entire Amiga 4000 to a python archive DAT drive. I backed up everything twice: once using Quarterback 6 and once using Amiback 2.0i. I used two separate DAT tapes.

I have stored them properly over the years and now wish to restore to share with my son. I have the hardware working (Amiga 3000) but I have forgotten my backup password to each backup (assuming they are the same).

Does anyone know of a hacked version of these programs or a way around the password protection? Neither backup is encrypted and the drive can read the volume names etc so I assume other than the password it's ready to restore.

Thank you.

Maybe the password is stored in the archives in clear text? Can you try BTN, CPIO, dd or TAR to see if you can stream the archive into a file and then inspect the file using a monitor program. Presumably the password would be stored at the beginning of the archive.

I'm absolutely certain that the password is stored in plain text somewhere at the beginning of the tape. I recall using a password but no encryption, a fixed block size and hardware compression.

I have a DAT drive on my PC running windows. I have Z-Dbackup installed. I'm not sure if it can read raw tapes not formatted by it.

I recall seeing DD for windows a while back that supports tape drives.

Thanks for the info. I'll experiment.
