If I boot my computer with a 10.04 Live CD - no trouble
If I boot my computer with a 10.10 Live CD - no trouble
If I boot my computer with a 11.04 Live CD - oops
The USB HDD is a Freecom Toughdrive - with hardware encryption - not enabled
In Windows the drive appears as a CD drive (with a virtual CD in it) plus an NTFS drive
The HDD drive is formatted by me into an EXT4 Primary and a then an extended and then a logical NTFS in the extended
Drive mounts fine in UBUNTU - both partitions.
Drive is bootable to Ubuntu
I will bring another USB HDD home from work tomorrow and see if I can replicate the behaviour
