I'm struggling against an HDD issue on a DELL Precision M6700 Laptop.
Hard drive is 500Gb.
At boot, message : "invalid partition table!". When plugged in my computer with an USB to Sata cable, i could see the "DATA" partition and backup the file, but the C drive was missing. Only 1 letter was available. This ends me try to use Testdisk.
I didn't made a backup at first, and i should... Anyway, as i remember, Testdisk could see the "DATA" partition.
With a deeper search, it found a "DellUtility" partition, and a list of 4 to 5 partitions. I tried to restore 3 partition :
- DELL
- C
- Data
I wrote the change but now it still doesn't work, and i can't see the DATA files anymore.
What i'm sure of, is the DATA partition was 162GB in Windows 7 (i checked it during the backup transfer).
So now, i need some help tryin to find what was there before (maybe tomorrow i could get my hands on a similar computer so i can check how is it).
I think the DELL partition is fine, i know the last partition should be fine too. At least, at the beginning... because the size was 162BG in Testdisk, like in Windows. So i made changes to have the NTFS partition of 302 GB for the C drive.
302 + 162 is 465GB, like detected by Testdisk. I thought it should work but it didn't. What should i do know ? Here's the last attempt with a deep search :
