WinUAE, Corruption in HDF files upon transfer?

[kd7ota]

Hello,

Few days ago I decided to pick back up the Amiga, but VIA emulation.

Years ago I made some HDF files in WinUAE and they worked fine... But now when I try to mount them and access them, all I get is that they are uninitialized, and when I try to boot up the HDF by itself, just says its not a DOS disk.  The only thing I could recall is that I transferred the HDF to my external drive from my desktop. Don't think my hard drives are bad nor is my memory starting to be problematic.

Anyone else had similiar issues? Is there some kind of software that repairs the HDF? The HDFs were never bigger than 4gb, one is 1gb and another 2gb.

Any input is greatly appreciated. Thanks!

After doing some messing around with an older version of UAE (1.5.3), those HDF files that the latest WinUAE (2.3.3) wouldn't work with worked great on 1.5.3. Wonder if there is something that changed that broke along the way? I made the original HDFs in UAE 1.5.3, but now wont work on the latest one.

Glad now I can do some backing up of files.

K, had to recreate the bug, and sure as hell it did it again...

So I made a HDF file under 1.5.3 that was 5MB in size, and then installed the basic 3.1 files over to it to make it  bootable. I then loaded the HDF over to 2.3.3, and it booted just fine... Ok, so I looked at the size of my workbench HDF from a few years ago, and it was 500MB, so I then made a 600mb file just to be sure I went over 500MB, and made it in 1.5.3. I copied over the files form 3.1 workbench disk to make it bootable.... I then loaded the HDF on 2.3.3 and BAM, says not a DOS disk. So somehow the HDF files that are being made in 1.5.3 are not working in 2.3.3 if they are bigger than a certain size...

So now you all know.

Check geometry (Surfaces, Sectors, Reserved, Block size) when adding a HDF. New WinUAE version chooses better geometry for big HDFs, but when using an existing HDF you have to enter the same geometry as it was created with (probably 1, 32, 2, 512).

Thanks! That pretty much nailed it on the head. Got an email about it too explaining it. Guess I was unaware of the differences and what was actually happening.

Thanks again for the input!
