16 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).
