Disk Checker

From RS Software Lab:

Disk Checker is a full-featured disk diagnostics and repairs tool with backup ability. This program runs under Windows 95/98/ME/NT/2000/XP/Vista. Disk Checker includes two separate methods of disk checking: using file-access or direct access to disk surface. The direct access method is much faster and is perfect for large number of small files. Disk Checker can report defective sectors numbers as well as the file name they belong to. Removable (floppy, ZIP, ORB, JAZZ, etc), hard and CD-ROM disks are supported when using direct access method. For above cases as well as for remote disks, RAM disks and network drives you can also use the file-access method. You can use this program for backup purposes as well. Disk Checker can create disk images compatible with disk image files produced by other disk copy utilities (Diskcopy, WinImage, DiskDupe, etc). Disk image is a file that contains all the disk data, such as boot sector, files and folders structure. It is possible to read and write disk images and format disk, including burning CD-ROM image .ISO files. Command line, logging and dedicated item in Windows shell context menu are supported.

Version 3.3 adds ability perform surface scan for non-admin users.
