Instead of disabling it, try to find out why it happens. If you just disable scandisk, a data loss is very likely to happen after a real hard crash. Especially if the FAT gets damaged and there's no scandisk run to copy over the backup FAT (you have that chance only once before any data is written to the disk after a crash).

I had this behavious with CF cards a few times because the BIOS would detect the card size wrong, making it believe there is one additional block at the end that doesn't exist.

I understand that, and I would have done that, if I was living back in 1997, but with the advent of the "cloning" software, and not having too much of a data loss to worry about (some few saved games, such as Quake 1, Hexen 1, and 2, etc., which I constancy backup to a flash stick) I am not that concern about data loss.

But you are correct nevertheless.

"If you find that your computer doesn't suffer any maladies after a forced shutdown, and nothing is reported as being wrong after ScanDisk autoruns, and you want to stop the automatic scanning, you have two options to prevent ScanDisk from automatically starting:
1. On the toolbar click Start, click Run, type Msconfig, and then click OK.
2. Click Advanced, and select the Disable ScanDisk after bad shutdown option.
3. Click OK twice, and then click Yes to restart your computer."

That is what I did, as every time scandisk runs, it simply does not find any error.

Thanks!
