Hi dears,
Here is the problem,
I have an external hard disk with four partitions.
I have been using it for a year.
One day I installed Folder lock software and locked the drives and unplugged it.
Another day I plugged the external hard disk and was recognized by the computer.
But I couldn't see the drives on my computer no did I see their letter labels.
For it is urgent, Sir/Madam, help me please as quick as possible.
Thanks for your immediate help in advance

Can you remove the Folder lock software? If that doesn't bring them back, you may be out of luck.
