While what Corazon has stated may or may not be true, let me ascertain the procedure to regain access to a lost drive using Test Disk. Not to give up easily.
1. Right click on testdisk_win.exe and
Run as administrator.
2. In the first window, select
No Log, and press the
ENTER key - makes life simpler.
3. The second window should show up all your drives including the lost drive. The capacities should be indicated correctly. Then you have life. Select the
lost drive,
Proceed, ENTER.
4. In the third window, select partition type,
Intel Intel/PC partition,
ENTER.
5. In the fourth Window, select
Analyze, ENTER.
6. Do all partition/partitions in the selected lost drive show up in the fifth window? Good going. Select
Quick Search, ENTER.
7. In the sixth window confirm whether the partition was created by Vista/(Windows 7). Press
Y if
yes/not sure.
N otherwise.
8.Seventh Window: Test Disk should indicate first partition of your lost drive as bootable and
"Structure: OK". Press
ENTER to continue.
9. In the eighth Window select
Write, ENTER.
10. In the ninth window confirm write partition table by pressing
Y .
11. In the tenth Window asking you to reboot, Press
ENTER.
12
. Close Test Disk and reboot.
At some stage or other, Test Disk will take quite a time so be patient. Get away from your PC with only occasional peeps to navigate and user commands are required.
