Hi Taco,
As per the description, I understand that you are getting an error **“****the system cannot find the path specified”**while plugging in a hard drive after factory reset on your Windows 8 machine. I will certainly help you in getting this issue fixed.
I would appreciate if you could help me with more information:
Did you try to perform the same task on a different computer/machine using the same hard drive?
If no, I would suggest you to try performing the same task on a different computer and check if that works or not.
Hope this information is helpful. Please write back to us if you need any further assistance, we'll be glad to assist you.
