This article was previously published under Q97041 SUMMARY
Disabling 32-bit disk access can improve hard drive performance if you
have a system BIOS or hard drive controller designed and optimized
specifically for your hard drive.
MORE INFORMATION
Some hard drive controllers have built-in optimizing routines that are
similar to those that the 32-Bit Disk Access system uses. In these
cases, 32-bit disk access can degrade hard drive performance because
some optimization routiness may occur multiple times for each disk
operation. This results in slower overall disk access.
Consult your hardware documentation to see if your hard drive
controller or BIOS provides any built-in disk access optimizations
that may make the use of 32-bit disk access unnecessary. Check your
Windows documentation for the advantages of using 32-bit disk access.
