Is my SSD dead?, Can I recover anything?

I have a Samsung 840 Pro 512gb SSD that will not show up in bios or the device manger. I have tried different SATA ports, different sata cables, and different power cables.

I tried it in a different computer and got the message: "Remove disks or other media" when it was the only hard drive available.

I really really need to grab some data from this drive. Is it possible?
 
Outside of a dirty or corroded SATA plug, it sounds like the drive has failed and professional recovery would be your only viable option. You can always try a Hail Mary like GetDataBack but this is not a good sign at all.

Desolder the ram chips in a clean room and transplant to another drive if the chips themselves aren't fried. They also have custon and unique hw/SW that might beable to read dead drives.

Why would you need a clean room to work on an SSD?

That is only necessary for spinning rust.

1: They already have the clean rooms for mechanical drives to begin with.

2: Minimize ANY outside factors when trying to recover a drive.
 
Maintaining (use) a clean room requires 'energy' and man-power, e.g. costs.
I believe, if it's not too necessary for just (de)soldering of chips, they won't use it to lower the costs and be competitive.
Most people you'll find in forums who do this successfully, don't have clean rooms.
And this salvage would work if the controller is at fault.
Again, it's amazing that people never learn a basic rule - backups. Here, we had a situation of a family with an ill son whose laptop contained a life-saving information about treatments. The laptop was stolen. They were on all news channels begging thiefs to return it. No words come to mind to describe this... most people are not "ready" to use modern technologies. Rememeber passwords like 123546?
 
Based on everything I have read, it looks like its the controller :(

Seems like its way too expensive to transfer the flash to a new drive, so I am shit out of luck..
 
Buy another drive and desolder controller?:(

I remember a lot of USB drives responding to revival with replacing the oscillator... Maybe same?

How long it lasted and how many TB read/written?
As a rule ALWAYS copy important data to other drive when you use SSD. Doing that once per 14 days means you lose only 14 days of work/important stuff.

Normally it would mean failure of components between NAND and MB, but some SSD are known to use poison pill, and kill themselves on reboot. I seen report of SSD that switched to read only, and then was completely inaccessible after reboot.
 
Might try the old stick it in the freezer trick. Sure its a SSD and not a spinner but at this point, not much to loose. Use a non Windows OS, sometimes they will read things Windows won't. If it comes up, copy fast.
 
I remember watching a video on Bitwit where he got a 'dead' ssd and tried a trick where you power it up and off a few times... something about it being in 'recovery mode' due to power failure? extreme long shot though.

this happened to me a while ago, was glad I had windows backup stuff turned on! that was windows 7 tho, could just clone image to new drive... windows 10 backup seems less straight forward

damn..

What do the professionals do that we cannot?

use acid to etch away the epoxy on the chips read the silicon directly or de solder them and read the nand directly. i know for sd cards they bypass the control chip and go for direct connection to the nand
 
The SSD mapping table and encryption key are very important. A loss of either of these could make recovery nearly impossible.
 
Data is spread across all the nand chips and that supports encryption then that will making recovery very difficult unless you can move the controller and nand chips to another board that is same as the old drive (another 840 Pro)

More then likely you had a nand chip fail witch renders all data lost any way
