Initially I formatted the disk on the Mac and created a single Ext2
partitition on it.
When I plugged it into the PC, hotplug detected the disk and loaded the
relevant modules successfully. However when I ran fdisk to determine which
partition was in use it complained that there wasn't a valid partition
table on the disk:
xena:~# fdisk -l /dev/sdb
Disk /dev/sdb: 40.0 GB, 40007761920 bytes
64 heads, 32 sectors/track, 38154 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Disk /dev/sdb doesn't contain a valid partition table
The same thing when there is no disk present gives no output at all.
If I format the disk on the PC the Mac sees a partition but fails to read
it. (Endianness issue in the OsX Ext2 driver?).
In each case the disk works correctly on the system on which it was formatted.
