This problem can be caused by various things. File system corruption, outdated BIOS, virus infection, Windows Service Pack, and bad sectors are some of the reasons for the error.

1. Virus Infection

One reason you could be having issues when you attempt to format your removable disk is due to a virus. Different viruses cause these issues among others. If the error is caused by a virus infection, you should install a protective application. If you already have an anti-virus, you should update it.

The file system of the partition could be damaged or corrupted. If this is the case, the formatting cannot be completed in Disk Management.

3. Bad Sectors

Bad sectors could also be causing the error. If you have confirmed that virus infection is not the cause of the error, check for bad sectors. Storage devices such as SD cards and disks have small units for storing data and they could be having bad sectors. With this, the sectors cannot be written or read as they are already damaged. This is what inhibits file recovery and the formatting process.

4. Outdated BIOS or Windows Service Pack
