This sounds like you are not cleaning the disk drive heads! Just about every time you dump a disk you are going to need to clean the disk drive heads. The oxide is coming off of the disk surface due to the passage of time! This oxide collects on the heads and distorts the reading (and writing). Cleaning is not optional.
grider Wrote:Yes, I'm positive that the scp was ran with Amiga mode for disk type selected each and every time. Otherwise it would not have worked in winuae, correct?
No. The disk type is ignored with WinUAE. You can use Amiga, PC, Mac, and other disk types with a real Amiga so the disk type is not used.
grider Wrote:All had 80 tracks. All 3 versions would not convert over to adf. I guess it is just a copy protection issue as you stated and that it's causing SCPro to throw that error "Image file is not for an Amiga disk".
No, SuperCard Pro doesn't know anything about disks. Please send me the .scp file you dumped of this disk to data @ cbmstuff.com. I can look at the image and tell you if your heads are dirty, drive speed is varying, and check the disk type. This particular disk (like 99.999% of all commercial disks) will not work when converted to .adf because it has copy protection.
grider Wrote:Thanks for the update too, I had forgot about that scp vs adf and copy protected disks wouldn't convert to adf or at least in most circumstances. Just got back into having 70 more disks to archive. So, I'm a bit bamboozled then on why 2 revs for this disk did not work in winuae vs more revs, if more than 2 revs are never needed. I'll have to try this again with 2 revs I suppose.
LOL! If you archived more than a hand full of disks without cleaning the heads and had good results that would be surprising!
grider Wrote:Edit: I tried another backup with 2 revs only and it still doesn't boot/load into the copier. Only a rev 3 and 4 will boot/load okay.
This is because WinUAE's .scp support allows the disk to "spin" multiple times while trying to decode sectors from poor data. The issue you are having is either drive speed (bad power supply to the drive or the drive itself) or the the heads and/or disk are dirty. This is the #1 reason for failures identical to what you have described.

No matter if I make an adf or scp it guru's on me with A1000 or A500 with kicks 1.1, 1.2 and 1.3 all in winuae. I'll have to test the original in one of my real Amiga's as I've not done that just yet. i guess it could be a bad original.
Make sure you are using the 68000 7MHz mode. A lot of the older Amiga games couldn't handle accelerator boards.
