Standard Windows disk scanning tools may not be suitiable for verifying read-only devices such as data CDs. Also when a program is intalled from a disk that is faulty, the resulting error message may be rather cryptic and not indicate any sort of hard error. This applet is designed to scan such disks to determine if there is a fault present.
- Whilst directory information may be read from the Windows file cache, actual file data is read directly from the disk without buffering.
- Files and directories on any disk can be scanned, however, other tools may be more suitable for detecting faults on read/write drives such as hard disks and floppy disks.
- Basic directory errors should be detected but some errors such as cross-linked files will not.
- All file data is read but discarded. If faults are present, read operations will result in errors that will be reported.
- If the listed file size is incorrect, this will be reported as a read error.
- If a file cannot be opened (e.g. because it is open by another process), this will be reported as an open error.
