In the SCSI controller BIOS setup, low-level format the drive using
your new controller. The drive was apparently low-level formatted on
on different controller, or simply contains a manufacturers' test
pattern. If you don't have a controller that shows a startup
window that says "^B or ^A to enter setup.." or something like
that, you need to format the drive on some machine that does.

Normally SCSI Direct-Access devices (Disks), have logical block
lengths that are powers-of-two. It is an important internal
optimization to select the proper head, etc. Therefore I doubt
that the "real" block-size is 2068. In practice, it's usually
512 or a multiple thereof.
