MORE INFORMATION
Defrag performs a conventional memory test prior to defragmenting a drive
by allocating all available conventional memory. The memory test consists
of writing all (1) bits to memory and then all (0) bits. It verifies the
write succeeded by reading back the value and doing a comparison. If the
comparison fails, Defrag reports the failed segment number.
