Hi,

Anyone has experience with this NVME Samsung MZ-FLV5120. Surface Pro 4 fail to boot. I took it out. When plugged to W10, it will ask for Bitlocker key (I can enter the key, press "unlock" but nothing, it's like I am not pressing "unlock" button) everything work on PC but if I try to do anything (open bitlocker from control panel) it will fail. Then after a while I will get "USB device not recognized by PC..."

Thanks
Sam

try cloning it first, then work on the clone. You never know when these things say goodbye.
Do you have recovery key and key ID?

The problem is I can't clone it as it always hangs after 1 min. Today I tried with another adapter. I could unlock, start to turn off Bitlocker then drive hangs...
I could see file system a couple of time but not enough to do anything.

Now I keep getting this "version error"which is not relevant. When I try to repair, scanning works for 3 min then error stat to appear. Looks to me like a damaged NAND.
Anyone has experience with NVME tool on the market (ACE, Deepspar) ?

Try to check the temperature of the device( Controller+ Data chip + other components ) when it goes to hang mode.

Ace & deepspar support this scenario, but overall depends the condition of the chip.

+1 for checking if it gets hot somewhere. Saw that problem several times.

There was no hot components however I could clone it. Took 5 days as NVME was disconnecting every 2 minutes, just enough time to read some sectors. Result is good.

My impression from the user forums is that all NVMe SSDs run hot. That's why they need heatsinks.

Also, if you are using a USB-NVMe adapter, be aware that certain bridges have stability issues:

Personally I would set up a test jig using a PCIe card plus an extension cable. The cable would be connected to a passive adapter which would ideally provide access to both sides of the SSD. I would then attach stick-on heatsinks to the major heat affected ICs.
