Of course I checked already. Your link does not address MY issue exactly
For many reasons, the insert disk error message appears when your USB flash drive or pen drive is inaccessible or unreadable by Windows. To fix this issue, you may format or partition the USB but hen you view the USB’s properties, the ‘Used space’ and ‘Free space’ on the drive are shown as 0 bytes.
- Check Physical Connections: Make sure the USB drive is properly connected and not damaged. Try different USB ports or another computer to avoid any port issues.
- Change Drive Letter: Assign a unique drive letter to the USB drive via Disk Management.
- Update USB Drivers: Use Device Manager to update or reinstall USB drivers, as outdated drivers can cause problems.
- Run Hardware Troubleshooter: Utilize Windows’ built-in troubleshooter to detect and fix hardware issues.
- Create a New Partition: If the drive shows unallocated space, create a new partition to make it usable.
- Format the USB Drive: As a last resort, format the drive using Disk Management or the Diskpart utility, noting that this will erase all data.

There could be several reason behind this Windows error. Here are some common ones:
- File System Corruption – Your SSD may have been improperly ejected or suffered a power failure.
- Partition Loss – The partition might have been accidentally deleted or become unallocated.
- Drive Letter Conflict – Your SSD might not be assigned a drive letter.
- Hardware Failure – The SSD controller or memory chips might have failed.
Here’s a full guide on how to fix the “Please insert a disk into USB Drive” issue. If everything fails, it’s best to take it to a professional repair shop. If it’s still under warranty, consider contacting the manufacturer for replacement.
As @Ellinor_William mentioned, this issue can happen due to file system corruption, lost partitions, or hardware failure. Try different USB ports, cables, or another PC. Check Disk Management—if it shows as unallocated, you’ll need to create a new partition (but this will erase data). If there’s no drive letter, assign one.
One more thing you can try is CHKDSK to check for errors. Open Command Prompt as Admin and type:
chkdsk X: /f /r
(replace X with your drive letter).
If the drive shows up but you still can’t access it, try using Windows Data Recovery Software before formatting. If nothing works, it could be a hardware failure—best to contact SanDisk support or check if it’s still under warranty.
