SanDisk Extreme Portable SSD Suddenly Not Recognized

Hi everyone,

I’m having a serious issue with my SanDisk Extreme Portable SSD and I’m really hoping someone here can help.

I’ve been using this drive for about 8 months without any issues. Yesterday, I plugged it into my computer like usual, but it didn’t show up in File Explorer. The drive itself lights up when connected, and I hear the Windows connection sound, but there’s no disk appearing anywhere.

What I’ve Tried:

  • Tested on multiple computers same issue on all

  • Tried different USB cables (including the original one)

  • Tried different USB ports

  • Checked Disk Management – the drive either doesn’t show up at all, or shows as “Unknown” and “Not Initialized”

  • Checked Device Manager – shows up under “Disk drives” but with a yellow warning icon sometimes

  • Tried updating drivers – no change

  • The drive light is solid on when connected

  • No unusual sounds coming from the drive

  • It was working perfectly the day before, no drops or physical damage

My Drive Info:

  • Model: SanDisk Extreme Portable SSD

  • Capacity: 1TB

I’ve been reading online and noticed many people reporting similar issues with this specific model. Some say it’s a hardware failure and the data might be recoverable only by professionals. Is that true?

Has anyone here successfully recovered data from this drive? Any DIY methods I can try before sending it to a data recovery service

Any help or advice would be greatly appreciated. Thanks in advance!

Stop all write operations to the hard drive immediately, then use third-party data recovery software to scan the drive and attempt to recover the data.

You might want to take a look at this; it might be helpful.

Based on my assessment, it’s probably broken, so don’t use it anymore. If you want to recover your data, you’ll have to use third-party software.

You can try the following steps:

  1. Force Windows to Reload the Underlying Driver

Sometimes, Windows device drivers become locked in an incorrect state. Forcing a clean reload can occasionally restore communication.

1.1 Right-click the Windows Start logo and select Device Manager.

1.2 Expand Disk drives, find the device with a yellow exclamation mark (or labeled SanDisk), right-click it, and select Uninstall device.

1.3 Disconnect the SSD, restart your computer entirely, and plug the SSD back in.

  1. Use Data Recovery Software

If the Windows File Explorer is blind to the drive, professional data recovery software can often bypass Windows and read the raw hardware sectors directly.

Open the software and look for a drive labeled “RAW”, “Unallocated”, or “Uninitialized” matching your SSD’s size. If the software successfully finds your files, immediately export them to your computer’s internal hard drive.

Never attempt to save recovered files back onto the faulty SanDisk SSD. (If the recovery software completely freezes, crashes, or hangs indefinitely while trying to read the drive, stop immediately. )

If Windows pops up a message asking you to “Initialize Disk”, “Create a New Volume”, or “Format the Drive” to use it, click Cancel. These actions write new data structures to the storage chips, which can permanently wipe out residual data and make recovery impossible. Do not leave it plugged into your computer for hours.
