SSD Not Detected After Windows Update: Fix It Without Losing Data

An SSD may disappear after a Windows update because of a driver change, BIOS setting, loose connection, drive letter conflict, or file system error. If Windows asks you to initialize or format the SSD, stop and recover data first.

First, Find Where the SSD Is Missing

• If the SSD is missing in BIOS, check cables, slots, enclosure, or firmware.
• If it appears in BIOS but not File Explorer, check Disk Management.
• If it appears as RAW, unallocated, or not initialized, avoid formatting before recovery.
• If it has no drive letter, assign a letter only after confirming the partition is healthy.

Fix 1. Check Disk Management and Drive Letter

Right-click Start and open Disk Management. If the SSD has a healthy partition without a drive letter, assign a new letter. If it shows RAW or unallocated, recover files before repair.

Fix 2. Update Storage Controller and SSD Driver

Open Device Manager and check disk drives, storage controllers, and IDE/ATA controllers. Update the driver or roll back a recent driver if the SSD disappeared right after the update.

Recover Data Before Formatting the SSD

If the SSD is visible to Windows but files are missing or the partition is inaccessible, scan it with Qiling Data Recovery before trying format, initialize, or clean commands.

Conclusion

When an SSD is not detected after a Windows update, locate the problem before changing the disk. Recover files first if Windows shows RAW, unallocated, not initialized, or access denied.
