5 Effective Fixes for Hard Drive Missing After Windows 11/10 Update

Use the following methods to find the missing drive in Windows 11/10.

Fix 1. Format the Hard Drive

If none of the above approaches is useful, the final way you can try is to format the hard drive for reuse. However, as we know, a hard drive format will delete all the data on the device. To avoid data loss, you need to restore the data on your hard drive in advance before formatting.

But how can you recover data from a hard drive that is not showing up in File Explorer? Don't fret. You can use EaseUS Data Recovery Wizard to do it easily. This competent data recovery utility is good at deleted files recovery, formatted recovery, RAW recovery, virus attack recovery, OS crash recovery, and more.

1. Recover Data from Missing Hard Drive Windows 11/10

Although EaseUS data recovery software allows you to recover data after the hard drive format, it is strongly recommended that you recover data before formatting to ensure complete data recovery. Follow the steps below to recover data from the RAW partition.

Step 1. Select and scan the RAW partition

If the RAW partition contains a partition label, you can directly select it from drives list and click "Scan" to look for the lost files. If the RAW partition lost its label, it will be recognized as "Lost Partition", just select the "Lost Partition" and click "Scan" to initiate an overall scan on the RAW drive.

Step 2. Preview found data from the scan result

After the scan is completed, all available files in the RAW hard drive will be displayed. View these files and find the files you want to recover. You can sort the scanned data by file format or search directly in the "Search files or folders" box.
