The ERROR_NOT_DOS_DISK error code often appears when attempting to access a disk or diskette that is not formatted as a DOS disk. This error signifies that the operating system cannot recognize and read the disk due to its incompatible format.

Fortunately, there are several ways to tackle this issue:

1. Check Disk Format: Verify whether the disk is formatted as a DOS disk or if it follows a different file system.

You can do this by right-clicking on the disk, selecting “Properties,” and looking under the “File System” section. If it shows a format other than FAT32 or NTFS, consider reformatting it.
