This is going to take a bit more than usual to answer. Let's back track 10 years. You really need to know what you have inside the case for more helpful answers.
(1) Formatting the original drive: NO... NO... NO.... Unless you have all the Toaster software, and manuals.
(2) System specs has not been declared. I guess: an original A2000 Toaster, AmigaDOS 2.04 likely, and a SCSI card, likely an A2091. No CD-ROM drive.
(3) Hard drive is less than 2 gig.
DiskSalv and using a 3.5" disk cleaner package was excellent advice.
I have A2000 internal and external floppy drives. If you need another SCSI hard drive for the transfer, I also have a few under 2 gig that I would pre-format to your specs. Let's not keep kids in the dark without morning announcements.
