SUMMARY
Norton Speed Disk versions 6.0 and 6.01 run optimally with MS-DOS version 5.0. However, Symantec states that using Norton Speed Disk with MS-DOS SMARTDrive cache loaded may cause corruption to the FAT (file allocation table). Apparently, SMARTDrive cannot keep up with the read-write activity of Speed Disk.

Norton Speed Disk versions 6.0 and 6.01 are the only Speed Disk versions that are fully compatible with MS-DOS version 5.0.



MORE INFORMATION
Speed Disk reorganizes the physical layout of all files and directories on a disk so as to minimize movement of the read-write head. It defragments files and puts all of the unused disk space on the inner tracks of the hard disk.

Speed Disk has a number of different optimization methods including variances of a full optimization, unfragmenting files only, and unfragmenting free space only. No matter which Speed Disk method you use, don't use SMARTDrive simultaneously. Symantec states that their caching utility, NCACHE, is fully compatible with Speed Disk.

The products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
