RDB-Salv requires OS 2.04 or later. RDB-Salv will speak to you in your own language as of OS 2.1, and OS 3.0 and later provides for enhancements relating to the GUI.
Of course you'll need a hard disk! The controller/host adaptor must not have too many errors. RDB-Salv goes to great lengths to work around device driver problems.
A significant Limitation must be stated now: RDB-Salv can only find AMIGA partitions. AFS, NetBSD and Mac partitions won't be found. The same goes for other unrecognizable partition types. However, RDB-Salv will in these cases, detect unused partitions and report them as such, so that it's possible for you to guess which of the unrecognizable partitions is which.
