Title: Suggestions for checking integrity of entire floppy disk?
Post by: orb85750 on November 16, 2010, 07:39:11 PM
Utilities that will scan the full floppy disk?  Will copy-protected software show disk errors even if the disks are actually fine?

Man, there's a tool I've not seen in a long time. Thankfully. I think that thing caused more problems than it ever fixed!

I remember diskdoctor for the C64.  I didn't even know it was available for Amiga.

I think it meant "doctor" as in the verb. Certainly it made a right hash of the one or two floppies I tried it on :)

hahahahahaha!  I never thought of it as verb!

seemed to me like 50% of the time, DiskDoctor did nothing
25% of the time it would mangle your disk even more
5% It'd rename it "Lazarus", and you'd be able to get a couple files off.

maybe.

OK, but to ask again, will a scan of a working copy-protected commercial disk show errors?

No.  The whole disk will look like gibberish to the program.

EDIT:  or the disk may look like it's full of errors even though its fine.  I think most custom disks bypassed the trackdisk.device

or something like that...

Disk Salv V4 is great. BUT, I don't know about using it on copy protected disks since some of the protection schemes were rather basic errors (and some not so basic)

Try making a copy of the protected disk, and run Disk Salv 4 on the copy would be my suggestion...

It can. However the first track must be valid or else the disk wouldn't be bootable. Assuming a custom trackloader is used the rest of the disk can be in whatever format the HW can read (the limitations are only set by the MFM coding (http://en.wikipedia.org/wiki/Modified_Frequency_Modulation))
