Normal DOS partition, with 512 byte block size, as this is 512B block device, at least I believed to it until now. As start=63, it apparently also handles 1024B requests on odd address (I believe that sfdisk -d dumps start 0-based).

/dev/hdc1 : start= 63, size=12685617, Id=83, bootable

Blacklist time. That, or decrementing size to 12675616, depending on whether you want that last half-Kb or not.

Last half-KB is useless, as filesystem on it is ext2 with 4KB blocks... Only problem is that previously stable system was now dying in e2fsck. I'll try to invent some solution before 2.6 ;-)

Maybe fix to e2fsck would be sufficient, I always thought that it reads disk in blocksize (4KB) chunks, so disk will not see 512B request. But apparently it either reads partition in 512B chunks, or block layer does not do merging correctly.

Guess where EFI puts partition tables 8(
