trying to transfer hard drives, didn't have the disk and didn't know about the disk and ended up configuring the hard drive as a flash drive instead
I do not think there is anything you can do about that OP. You could try giving support for your region a ring but aside from that I'm not sure there is anything else to try.
Did this solve your problem?
Sorry this didn't help.

This is very common when using third-party transfer cables. There is nothing that can be done to return the HDD to its previous state.
