Unable to access external hard drive (Toshiba Canvio Premium)

Sep 23, 2018
I've had my Toshiba Canvio Premium external hard drive for a few months now, using the provided encryption, without any problems.

Recently, I decided I would factory reset my computer (Windows 10) and save the files I wanted to keep to the external hard drive. Upon saving my data to the drive and resetting my computer, I plugged the drive back into my computer and received no prompt to enter the password for the hard drive.

In an attempt to find the issue, I ran the Toshiba diagnostic tool on a full scan and the drive passed. I then checked disk management to find the message "You must initialize a disk before Logical Disk Manager can access it.

I've tried uninstalling and reinstalling USB drivers with no luck. Is there any other fixes that I might be able to try to access my data or get the drive to work again without wasting money on software to recover the data?

Edit: I did have the Security Software downloaded, which didn't recognize the drive either
