hello,

I saw many trouble with this SSD ... and I've a trouble

I worked and suddently my computer was freezed . I tried to restart and nothing happened

if I put this SSD on another computer with another disk, start is very very slow ( boot is done on the another disk) .

on the explorer, 870 disk is seen with 2 partitions but I'm not able to go inside. In the device tab, I can see this disk ( a least name). On the partition tab, I can see 2 partitions.

If i use magician, after a very long time, this 870 evo is not seen .

i saw several topics for this model but I didin't find how to try to repair my disk to retrieve datas ...

if someone have an idea, i'll be happy , thanks

It cannot be repaired, due to nand flash degradation & possibly now has turned into a firmware problem.
Shut it down and clone it, if still possible, with something like ddrescue or hddsuperclone (check their tutorials).
Then use data recovery software to recover the files to yet another drive.

Otherwise, find a data recovery specialist (not a computer shop).

hello Labtech,

I'm not able to clone this disk;( so only way is ask to a specialt?

Thanks

I've had a number of these where although the capacity is correct the UA was not accessible despite my best efforts and they've had to be returned unrecovered. There is no support for EVO's in pc3K, if it's got that far you can try a dr lab but manage your expectations.

hello Lardman,

thanks for your answer. so disk to the bin

do you know if there is a way to have a SWD or JTAG pins on PCB? I didn't find a datasheet

I think people use something like JTAGulator.

hello all

Thanks a lot for your answer. So I think if I m able to change controler, it ll work?

Nope, controller is most likely just fine.

Unlikely - the controller itself is probably fine, the firmware is stored on the nand chips .

Thanks a lot Lardman, it is very interesting ! I ve to read this pdf in details and learn more !

hello
so it does mean, even I m be able to find jtag or swd, i should "dump" flash but it ll be in raw and I'll not be able to recover something because at least it ll be xored and data could be everywhere.... I'm right ?

you cannot dump NAND through jtag, at least not as easily as you probably think. It would require programming skills in multiple platforms, or knowledge about boundary scan parameters, and on top of that it would be very slow. Then you would face the problems everybody faces who tries chip-off on these...

hello,

for your information, trouble was too many error on the nand. PC3000 was able to read this ssd and retrieve some data

Thanks for confirming the initial diagnosis suspicion.
