The PC+CDR option sounds better. Less wasteful.

The catweasel itself doesn't do disksalving. This is where it gets complicated. You make an ADF of the bad disk, use UAE and run disksalv on it, then save the fixed ADF.

Or you could just use disksalv on the Amiga, save the files to another floppy, and make an ADF with that on the PC catweasel.

I have a Catweasel Mk.3 PCI plugged into my Pegasos currently, and it's just like using an Amiga floppy disk drive - I don't need to make ADFs or any of that. But the Windows version isn't quite like that, as far as I know. At least it wasn't; maybe that has changed. Certainly the Mk.2 could only make ADF - but this is very old now. I'm sorry I don't know more. A lot of people will know more than me if it's possible to use a catweasel directly from Windows/UAE like an old floppy drive.

Here is the problem with making ADF - the drive only 'lifts' what it can from the disk. If there are hardware errors it will simply read what it can - or fail completely.  I think the way disksalv saves files from bad disks is that it reads them again and again and again until it gets a good checksum. A catweasel won't do this when it ADFs a disk (although it has better error recovery than an old Amiga drive). This could be a problem if you have many bad disks...

It sounds kinda weird that DiskSalv would be able to work on just a pretend disk.


Disksalv doesn't know it's a pretend disk - it just does its job.

So I take it that DS on UAE on a pretend floppy would take no time at all, right? Have you had success doing DS on UAE on pretend disks?


It's very, very quick. I've used it on ADF and FMSDisk images (a sort of ADF-like 'fake' floppy), ram disks, and such. But since these never really have hardware errors, only undelete, validate, and unformat are useful.

You can get Disksalv 2 from Aminet. DiskSalv 3 is commercial and can only be bought - but who from these days, I have no idea.
