ERROR_WRONG_DISK
The inserted media does not match the expected volume
ERROR_WRONG_DISK indicates that Windows expected a particular removable volume but found different media. Software may encounter it when a drive letter is reused, media is swapped, or a volume identity changes during an operation.
Checks
- Compare volume serial number or other stable identity, not only drive letter.
- Prompt for the expected media in interactive workflows.
- Detect media-removal and arrival notifications.
- Reopen handles after a verified media change.
Handling
Do not write to the newly inserted disk under the assumption that it is the original target. Require explicit confirmation or matching volume identity.
