Let me know if that doesn't do the trick. Thanks!
I have stopped at step 3 as toughdrive isn't listed.
It does not appear at all under disk manager. Under Device Management, if I look in USB Controllers I see a list which includes a mass storage device and when I right click on it, under properties it says it is a USB to serial ATA bridge. When I unplug it, this entry disappears.
Ok thank you. Hope the drive hasn't failed. Will cry! I just sat down to transfer all the data as I am leaving my job, keeping fingers crossed. Thanks for trying.
