Hello I have found this Super User question, but the few replies/solutions ended up being not the ones that made sense
Since I solved my issue, and it required some researches,
I'd like to share with you what I had learnt.
P.S. SSDs are again FLASH memory devices, but the recovery process is different.
Unfortunately when a pendrive is not CORRECTLY detected, like:
it changed its name into
- PRAM 2261
- PRAM 2267
- PRAM 2268
- PRAM 2303
- PRAM 2307
- others PRAM xxxx
or when it is plugged to your Windows PC it throws the message USB Device Not Recognized
or it is detected but with WRONG CAPACITY like some 0MB or 8MB instead of some GBs
or it asks to insert a disk into removable disk
the problem is UNFORTUNATELY not software or driver matter
the MCU controller of that FLASH memory is slightly damaged, heavily damaged or either just dead. In the worst case, it is/they are the FLASH chip/s that are damaged/dead , but this looks a rare occurrence, less than 5% of cases.
Also note: FLASH memories, since some years now, use dynamic XOR coding when writing into chips , so neither swapping the contoller (given that we find the same one with same release version) will help
At that point, if you need the data, the unique solution is to find a company that is equipped with FLASH memory data recovery devices like (in alphabetical order):
- Acelab PC-3000 FLASH
- FLASH EXTRACTOR
- RUSOLUT Visual Nand Reconstructor
(hey! They are all Russian manufacturers, looks like they are the experts in this field)
There the FLASH chip/s will be unsoldered and read with one of the above specific FLASH data recovery devices
Unsoldering and dumping the FLASH NAND chip content won't be enough.
Next the dead MCU logic must be rebuilt with the dedicated software bundled with the device, since the FLASH chip content is not contiguous
This data recovery process has a name: it is called CHIP OFF DATA RECOVERY
I'm in Italy and I've sent my dead pendrive to this Pendrive data recovery company. I have personally been there and they kindly showed me the PC-3000 FLASH device an their micro-electronic lab for the unsoldering operations
They kindly explained other interesting things like: in the majority of the cases, 95-97%, luckily the issue is a damaged/dead controller while the FLASH chips are healthy.
This mean that in 95-97% of the cases, when there is a FLASH memory with physical FLASH NAND chips, the recovery will succeed. Another story are the monolithic FLASH memories, like microSD and some gadget pendrives or most of PNY flash memories.
NOTE: SanDisk is often a bad issue they explained, because SanDisk transparently encrypts the FLASH chip content and not all the cases can be decrypt
So I have been lucky, I was NOT in the 3-5%, my thumb drive was NOT SanDisk and so I got my data back.
About chip off , together with the data, they returned to me my BGA FLASH memory chip, which was obviously unsoldered from the pendrive's PCB...
So if your pendrive or FLASH memory device is dead or shows one of the symptoms described above,
and you need the data or pictures in it,
the solution will be to search for a similar company in your country
submit the memory
and cross fingers :-)
About the cost? Usually they are described on the respective websites, but always ask for an email with MAXIMUM price confirmation.
