Question Drive D suddenly disappeared from Explorer (Error)

[DragoWeb]

Hi everyone,

my Windows 10 PC no longer recognizes my D drive (SSD Samsung 870 EVO 1TB, about 1 year old).

I was downloading something onto this drive and then the laptop suddenly shut down for some reason when I just moved it. When I turned it back on, there was no drive D (Disk 0 Dynamic Error).

I tried the following:

- Unplug the SSD then plug it back in (PC off, of course).

- CMD Diskpart > Online Disk.

- Convert the partition from dynamic to basic with Easus Partition Manager.

- Manually mark a disk as basic using the HxD hex editor.

Nothing worked. Finally, I did a full recovery with Disk Drill to recover as much data as possible, and now I'm getting ready to try a few other things, but first I'm wondering if there's a way I haven't thought of to recover the partition and everything else... Help! 😬

Welcome to the forums, newcomer!

By the looks of things, you should perform an RMA(as it seems to me you yet have warranty on the drive).

Samsung 870 Evo -- is it a dud model?

BTW, Diskdrill is a second tier data recovery tool. There are many better professional tools for far less money.

I've already managed to recover quite a few files with Disk Drill and now I'm rescanning the drive with Raise Data Recovery. Thanks to both of you for your advice, @Lutfij and @fzabkar 🙏🙏, I'm going to return it to the seller under warranty.

I've also upgraded the firmware on my other Samsung drives (980 PRO and another 870 EVO) because from what I've read on other posts and some other forums there are some reliability concerns on certain models...

WOW! R-Studio is really powerful! Where Disk Drill only recovered a part of the files, without the original file names and without the tree structure, R-Studio recovered all the files, even those in bad sectors (but without being able to restore them of course), with the original file names and tree structure! I'm really impressed 😳 Thank you so much @fzabkar 😁

Hard to choose which is the best answer, but I'll select @fzabkar as I was able to recover almost all my data thanks to him, even if in the end the real solution was given by @Lutfij (sorry and thanks again to both of you 😅)

To be fair, you should only be comparing tools when they are all working with the same data. To this end you should clone any unstable source drive to an image file or another drive. You should then run your data recovery software against the clone. The reason is that an unstable sector may read OK on one attempt, but may fail on other attempts. The cardinal rule of data recovery is never to recover the same sector twice. If you can read it, save it -- you may not get another chance.

A tool such as HDDSuperClone (now OpenSuperClone) is a multipass imager. It will clone the easy sectors on the first pass and then try the more difficult sectors on subsequent passes.

Thank you very much, this information will certainly be precious if it happens to me again. 👍 But I hope I'll never need to use it 😁
