SSD appears in BIOS and Device Manager but not in Disk Management or any other tool

After a crash a few days ago, my SSD wasn't detected in the BIOS (or anywhere) anymore for a while.

After trying everything, I decided to try to put it in the oven to re-flow the solder before tossing it, and it actually "worked". The disk is visible again in the bios (every time, reliably), and in the Device Manager on Windows (installed on another HDD), correctly recognized as "SanDisk SDSSDA240G", displayed as working correctly.

Problem is, no drive letter is showing up. If I open the Disk Management tool, the disk isn't there (not even as unallocated space).

I also tried a bunch of tools, and none can see the disk exists :


  • ■ Diskpart : list disk (both from Windows and from WRE booting from install disk)
    ■ Testdisk (both from Windows and from booting on a USB flashdrive Linux distro)
    ■ Partition Wizard (from Windows)
    ■ fdisk, hwinfo, ... (from Live Linux)

I'm probably forgetting more, but they all have the common point of acting as if the disk wasn't plugged in at all and not listing it anywhere, despite it appearing in the BIOS (and in Devices Manager).

After activating SATA hotswap, I was able to have the disk actually show up on Testdisk (booting from flashdrive) by pluggin it after boot, but when I tried scanning it it gave a "Read error" on every sector.

If I hotplug it on Windows, the new device sound plays correctly and it appears in the Device Manager, but that's it.

It's probably hopeless but if anyone has an idea, I'll try anything at this point! Thanks

OS: Windows 10 x64 Pro

SSD : Sandisk SSD Plus 240G
MB : MSI Z68S-G43 (G3)

Edit : Forgot to mention : I have an USB enclosure, and the problem is exactly the same with it (Gets installed successfully after plug-in and shows up in the devices manager, but only there)

Hello... re-flowing use as well as soldering irons are well populated across the desks and tool boxes of a many technicians... factories and homes... it's basic metallurgy... and understanding and controlling the Heat applied to a electrical/mechanical connection... not un-common to find them plugged in and turned on at the start of a Work day. (As well as the machine shop Heat treating ovens)

The increase in this type of activity is more common these days due to the 'Lead free solder"... the softness of the lead in the MIX proves to be a better for devices over a wider temperature range and vibration/physical abuse. B /

I'm proud of your efforts and attempt here... As I would be expected by my supervisor/management to Do... try...

Nothing. It didn't show up in the BIOS on multiple computers and didn't show up on USB either (enclosure wouldn't even lit up), I tried every fix I could find online for several days and no matter what I tried it wouldn't appear.

I decided it was dead and gave up, so before throwing it away I figured I could have some fun and try the oven trick I read about earlier... and here we are!

Seems like the only way to download a Sandisk firmware is a Windows tool, which doesn't detect the disk either... (Sandisk SSD Toolkit/Dashboard).

Anyone with a Sandisk SSD Plus 240GB? Would be very grateful if you can send me the file!

Hello... I found this for app and command lines http://www.tomshardware.com/forum/272939-32-update-firmware-flash-drive

I sounds like you must contact/email them for the firmware... they don't post a public firmware page at this time?
https://kb.sandisk.com/app/answers/detail/a_id/15581/kw/ssd%20firmware%20Sandisk%20SSD%20Plus%20240GB

And their "Dashboard software" is able to create/burn a USB bootable stick, but like you said Windows could be interfering with the "Dashboard board' software to get it to trigger.

I've flashed a lot of devices... but haven't had the Joy/procedure yet of a damaged SSD in DOS mode... looking at the reviews on the egg page for my ultra II 480... I sometimes worry I could have a specimen on my hands. B o
