- HDTEST allows thorough READ/WRITE testing of a (hard or
- floppy) disk without loss of data.
-
- The (Shareware) version of HDTEST allows thorough,
- comprehensive Read/Write testing of hard and 5.25", and 3.5"
- floppy disks on IBM PCs, XTs, ATs, and most reasonably IBM
- compatible clones. It can also be used to test almost all
- DOS-accessible storage devices currently in use on MS-DOS-
- compatible computers, including removable (floppy and hard)
- disks and logically partitioned hard disks. HDTEST can
- thoroughly test the magnetic media on a device which
- contains data WHILE PRESERVING THE DATA (although data loss
- is unavoidable if an area which is in use has become
- unREADable). HDTEST normally tests the disk much more
- thoroughly than programs such as DFixer, Mace, and
- Norton's DT, because it WRITES AND reads multiple test
- patterns on every sector on the disk, and because it gets
- below the DOS level to detect errors which are minor enough
- to be ignored by DOS but may nevertheless warn of developing
- problems. In addition to its testing function, HDTEST has
- been reported to be useful as an automatic disk repair
- utility for both hard and floppy disks which develop
- (especially) intermittent or persistent read errors,
- preventing or impeding their normal use. Both versions of
- the HDTEST package include full documentation on disk and a
- second program (HDCHEK), which does not write to the disk,
- and can be used to check that a given hardware/software
- combination is compatible with HDTEST.
