Hi,

I am using djgpp version 2.01 and scitech graphic libraries. The program
I wrote ran on my Windows 95 PC boot to MS-DOS mode only and use
cwsdmi.exe to run in protected mode. It works fine on my MMX desktop.

I ran the same program in HP OMNI BOOK 800CT MMX (boot to MS dos mode
and use cwsdpmi.exe) and after the first run, the file system is
corrupted and a few clusters were reported by scandisk as having
physical damage. Uncovinced, I tried running it on a second OMNI BOOK
800CT and after a few runs, the c:\windows and the subdirectories
disappear and scandisk also reported that the some clusters have
physical damage.

The program also uses milisecond timing routine from PCTimer14 (Chih-Hao
Tsai).

My question is : is it possible for a program to cause  physical error
on the harddisk (at least as detected by scan disk) ?

I would appreciate any comments.

Thank you.

Suryani.
