You could try Testdisk[1]. It may help. The data on a SSD is not |
17 |
necessarily stored linar so it's not said that a new partition is using |
18 |
the same memory cells as the old one. Even if it is, you'd lose any |
19 |
information about directories or files (names, dates, accessrights and |
20 |
so on). |
21 |
You should definitly try to minimize writes (ideally there would be |
22 |
none) since they can corrupt data. For a HDD I'd advise to create a copy |
23 |
using dd but from my understanding of SSD technology it's not |
24 |
guaranteed to copy the right (now unused marked) blocks. |
25 |
If you can't recover the old partition information I'd say you lost your |
26 |
data unless you are willing (and there's no guarantees either) to pay |
27 |
substantial amounts of money to specialised services (substantial as in |
28 |
most likely >> 1000 EUR). |
