"WARNING: end of partition > size of disk!" in log

[mark_k]

Looking at the winuae log (I'm testing with 2.4.0 beta 23 but assume this applies to 2.3.3 as well), I noticed that WinUAE shows a warning about the OFS ~48MB boot partition in my hardfile. It says "RDB: WARNING: end of partition > size of disk!"

Extract from the log:

What is the size of the physical file? WinUAE thinks it is only 4294967296 bytes.

Oops. I thought it was 429M, not ~4G

EDIT: is your hdf complete? RDB says it should be about 9G and 4294967296 bytes in dec = 0x100000000 in hex.

[mark_k]

By my calculation, the last byte of the last partition on the disk is at offset 4,294,655,999. The image file is 4,294,967,296 bytes long (i.e. exactly 4GB). So there are 311,296 spare bytes at the end.

I guess it might help if I send you a dump of the RDB area?

[Toni Wilen]

RDSK at 0, C=8925 S=400 H=5

This makes 9G.

Partitions are probably correct but UAE also complains about this size information.

Ah, that could explain it. The original physical drive was a 9.1GB IBM SCSI hard disk. But when partitioning it I only ever used the first 4GB, so all partitions are within that region. (Didn't want the hassle and risk of using a program like NSDPatch to enable 64-bit access.)

Could the log message be a bit clearer? Since AFAIK there are no partitions beyond the size of the image file.

Latest beta should improve this.
