Error Message:

Format failed.

Explanation:

The formatting of an NTFS partition could not be completed, possibly because of unsuccessful write operations due to bad sectors on the disk.

User Action:

Do not use the /q switch on the Format command. Reformat the disk without the /q switch, which will avoid writing to the bad sectors. If this message reappears, there is a hardware problem. Either run hardware diagnostics on the disk and its controller, or contact the supplier of the disk.
