Please let me know if this is a new drive and if you need to recover data. The course we need to take in order to tackle the issue depends on the data recovery matter. If you have important files which you need to retrieve, this means that you shouldn't try to initialize or format the drive, because that's data destructive and you'd probably lose everything.
Also, what do you when you say that you can't "initialize" the drive? Is the option greyed out?
