@edembowski: Just so I understand, you were in avos, you plug your A5 in a mac and it shows 63 extra sectors? I can tell you that the extra 63 sectors are actually where the hidden partition is stored, but I don't understand why the mac see it and not linux.
You're right, that's very strange. I think it may just be a difference in how it's reported.
... Try to mount with the -o offset parameter like this:
mount -t ext3 -o offset=??? /dev/sdb /media/disk
I don't think the Mac supports the -o offset parameter, since that's just passed through to losetup. Right now I'm booted under Linux. Looking at the table,
root@lizard:~# fdisk -l /dev/sde
Disk /dev/sde: 249.7 GB, 249727726080 bytes
255 heads, 63 sectors/track, 30361 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sde1 1 30361 243874701 c W95 FAT32 (LBA)
I should have offset=249727726080. No joy. Looking at dmesg, I have "VFS: Can't find ext3 filesystem on dev loop0." for every attempt. If I convert that to sectors, I should be able to
dd if=/dev/sde of=ext3.par skip=487749465 bs=512
but that gets no joy as well. I'll try the dd under MacOS to see if the results are the same. I'm beginning to think that I should either open the archos or get the battery pack.
