Disk Checker is a versatile disk tool that performs diagnostics, repairs and backups. Compatible with Windows 95 through Vista, it offers support for command line, multiple media types, logging and a dedicated menu item in Windows shell context.

Disk Checker reports the number of defective sector numbers and the corresponding file name during direct access checks. You can check removable disks, hard and CD-ROM using direct access (administrator rights required on Windows NT/2000/XP) and the file-access method is suitable for remote disks, RAM disks and network drives.
In addition to diagnostic and repair tasks, you can also use Disk Checker for backup purposes. You can create disk images in a compatible format with other disk copy utilities like Diskcopy, WinImage, DiskDupe, and more. A disk image is a file that contains all the disk data, including boot sector and files/folders structure. Disk Checker allows you to read and write disk images, format disks and burn CD-ROM image .ISO files.
Finally, it supports logging, command line, and Windows shell context menu. All in all, Disk Checker is packed with features and is a worthy consideration for anyone looking to ensure the optimal performance of their disk drives.
