I have never seen that happen with Acronis? (Having siad that I haven't used the Home version for ages).
TrueImage should see all partitions on all attached drives - ATA, SATA and attached USB/Firewire devices.
If it doesn't you may find the partition table has been damaged and it can't read it - have you tried checking the partition table on the second drive?
Thanks for the reply, Carol.
Turned out that the second drive was a dynamic disk (!??!)
It was slow as molasses on Marmite -- took about 5 hours to copy off 20Gb of data.
Once I had the data off I killed it and reformatted.
I've heard a lot of good about Acronis, but I'm certainly unimpressed by its removal routine.
Perhaps there's something in the documentation that I missed -- I didn't set up that machine.
The Home version wouldn't have been my choice.
It's my week for computer glitches, evidently.
Just lost one HDD and now I need a new chip cooler as mine's starting to grumble (unrelated events).
