Emsa DiskCheck is a dual-purpose utility, for disk checking (prescan and full disk reading) and also benchmarking. What it does, is scanning/reading the entire contents of a disk (CD, DVD or hard drive; or even floppy) and show any read errors that may appear, but also show drive speed information, progress statistics etc. It was designed with simplicity in mind, but usefulness for the user. We can use it to do a full check of the surface of any disks, for example if we have just scratched a disk and want to see if it is still readable, or if we want to check all our cd library for time or usage related faults. We can also use it for drive benchmarking, easily comparing speeds through "X" speed multiplier factor, in real conditions. We can also scan hard drives or even floppies - and get real condition performance information accordingly with drive performance but also with the way data is stored on it, which obviously impacts on overall performance. Make sur we clean the CD or DVD before doing tests, to remove dirt and ensure tests are accurate.

Unistal Disk Repair is a logical bad sector removal and repair software that removes the logical bad sectors and repairs "Track 0 Bad Disks". Bad sectors are a major problem in hard disks, which are found to be mainly logical in nature. Computer companies usually have to replace the hard disk. Most often bad sectors spread and corrupt Track 0 of the disk due to which it doesn't get formatted, O/S doesn't get installed or copying data gives error. Logical bad sectors are irregularities on the magnetic media formed due to extensive read write operations, sudden voltage surges, certain viruses, corruption's in boot records etc. Disk Repair is a hard disk utility that repairs the logically formed bad sectors. Disk Repair realigns the magnetic orientation to make each byte read and write able and hence perform the easy hard disk space recovery. The software is simple to use and is helpful in many instances of disk problems. Removing bad sectors using Disk Repair will clear off all data/files/folders. If we have important data, it is advisable to recover our data before bad sector removal. Use Quick Recovery to recover data.

Ariolic Disk Scanner is a freeware tiny utility to check the hard drive for read errors. Disk read errors may be the first typical sign of the possible disk failure. Ariolic Disk Scanner makes a raw sector read check of the hard drive and shows the result as a picture of our disk, where the good and bad clusters marked, so we can see the status of our disk at a glance.

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 (you must have administrator rights to perform hard drive checking under Windows NT/2000/XP). For above cases as well as for remote disks, RAM disks and network drives we can also use the file-access method. We 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.
