I was having problems with my hard drive. While trying to repair it I got a notice saying that it couldn't find a hard drive. Out of curiosity I restarted the computer and turned on my external hard drive. THe computer gave me options to install windows on the external. I cancel because I didn't want to lose all of data. I didn't think anything really happened.
Since then my computer reads the external as a hard drive and not as removable storage and it's completely full and won't open.
Please help if you can!
