You can control whether and when ScanDisk scans the hard disk on boot up by setting the autoscan parameter in the Options section.
[Options]
AutoScan={0|1|2}
0: do not scan
1: scan if irregular shutdown (default)
2: scan every boot up
Windows 95 OSR2 resets a bit in the Master Boot Record (MBR) every time Windows shuts down normally. If this bit has not been reset, Scandisk will run the next time that you boot the system. If you a have a third party scan utility you may wish to use it instead of Scandisk and thus to disable Scandisk at boot up. If your hard disk is having problems, you may wish to test it every time you boot the system.
You may have to add the AutoScan parameter to the Options section, if it is currently set to the default value of one and not explicitly listed.
