Agreed with post 3 above.
DO NOT use that drive for anything.
DISCONNECT IT and put it aside until you have run some data recovery software on it.
You need data recovery software.
Some that come to mind are:
- DataRescue3
- Stellar Phoenix Data Recovery
- Disk Drill
ALL data recovery apps work roughly the same way:
1. You download the app
2. You launch the app and "aim it" at the problem drive
3. Generally the app will offer a "deep scan" choice, use that
4. The app will scan every sector on the drive, and present you with a list of files it believes are recoverable, BUT
5. The app will only let you recover ONE file. The purpose of this exercise is to let you see if there's a decent possibility for data recovery BEFORE you pay the registration.
6. If this works, you now pay the registration, get a code, enter the code, and let the app "go to work" on the problem drive.
Important to understand:
- You will probably lose all previous folder hierarchies.
- You probably will lose many file names.
Both of the above are "par for the course" with DR software. The consolation is that you get the data itself back.
You WILL need ANOTHER external drive of sufficient size, so that the data recovery app has a "scratch drive" on which to assemble the recovered files.
