Yes, that test is for the Simtec.

Ok. Swap the "SWI"s for "SYS" and it runs

I'm hoping the attached will detect which drives are valid on the APDL to avoid the lock - you should see the drive(s) and partitions. It should also detect the drives on the Simtec, although currently won't show any partition information.

Simtec (A480) says "Number too big in "Formats.Filecore" at line 95".

255 heads (@ +2) and 255 sectors (@ +1), with a non-ADFS partition of &42 (@ +3C) at cylinder &FFFF (@ +3D/3E) - no wonder it errored, the Boot DiscRec isn't valid (or the Simtec is using it for partition information?)

Try the attached, I've put some basic validation on the non-ADFS partition value.

Yep, but the window won't go wide enough to show them all

There's also an "ICS" below the drive icon on the left, which is obviously wrong.

And they all show "Boot" which I'm guessing means you think there's some OPT 4 set, but there isn't on all the partitions. (Maybe I'm wrong about this, but I don't know what "Boot" would mean for every partition, otherwise?)

The sizes and free space is correct - drive :3 really is only 322MB, as that's the 4GB card filled up.

Well it runs now. Only the one partition shows, as you suggested. But ... it's showing as Arc2 / ":2" for some weird reason, which is the 7th partition (of 8).

That's actually correct, it's the partitioning used on the physical drive.

That comes from byte 7 of the DiscRec.

Could you post a debug log please. It currently gets it from the Boot block DiscRec - I might have to switch it to the DiscRec in the middle Filecore Zone

I was expecting it to show as unpartitioned, but it must have found a FileCore structure for "Arc2" at &C00 which is IDEFS::2. If you post the debug/txt I can confirm what it found at &C00.

That would imply the Simtec partitioning information is possibly sitting in the FileCore area between 0-&C00. I'll see if I can find anything obvious in the Module that reads that low and failing that, we'll grab the sectors from your drive.

Oh. Well calling it just "ICS" isn't really right then. "ICS/APDL" perhaps. There's nothing to indicate what that text means.

Searching for mounted drive IDEFS::Arc2
Matching FileCore disc found as IDEFS::2

As I suspected, it fell back to check for a full-disc FileCore drive as I've not implemented the Simtec partitioning. There's a DiscRec @ C00 for an A480_2 drive - possibly from before the drive was partitioned. The size of the FileCore drive pointed it to Zone 63 at LBA &7CC80 for the full DiscRec - which just happened to be the full DiscRec for Arc2.

To avoid the false-positive, I'll add some additional validation on the Boot DiscRec.
