Method 1: Mount the Partition
The first and safest method you can try is by mounting the partition again. If mounting works you will regain access to the contents of the partition and safely copy them to another location. Follow the simple steps to do so.
- Update the disk drivers.
- Run the chkdsk command and sfc command to check the system and the drive for errors.
- Attempt to remount the partition.
- Press Windows + X and select Disk Management.
- In Disk Management the unmounted partition will show up with either Offline status or as Unallocated space.
- If it shows with Offline status, right-click on the drive and select Online.
- For Unallocated space try assigning a drive letter. If this option is not available, you will have to format the partition to mount it again. This will lead to data loss so do not try this.
Even if you are unable to mount your partition, you can still try recovering your data.
Method 2: Boot into Live Linux CD/USB (Advanced Users)
- If you are comfortable with a more technical approach you can also try booting into Live Linux CD/USB.
- Your partition is unmounted, which means that the Operating System is unable to access it. By booting into a different OS environment like Linux you can bypass this issue and regain access.
- If your partition is accessible in Linux simply copy its content to an external storage device. You can keep the file format of the external drive Windows compatible. Linux supports Windows-compatible file systems also.
