When I try to run Scan Disk it keeps resetting. How can I get it to run?
Scan Disk (Error Checking in XP) will keep resetting if Windows is performing background tasks. Many times you are not even aware that these are happening, nevertheless they are there and can get in the way of a good scan.
There is a way to get around this: just as your computer starts to boot up (before the Windows "splash screen" appears), keep hitting F8 on your keyboard. A menu should come up. Choose the SAFE MODE option then run Scan Disk following the normal procedure and it should work just fine. When done, re-set your computer and be sure to switch back to normal mode.
Windows 95/98/ME Users:
Click on the Start Menu then select Programs, Accessories, System Tools, then Scan Disk. Select the drive you would like to check, then select the type of test you would like to run (standard or thorough). Finally, click Start.
Double click your My Computer icon. Right click on the C: drive. Select Properties then choose the Tools tab. Under Error Checking, click the Check Now button. A dialog box will pop up, check both check boxes and click Start.
A dialog box will pop up telling you, "The disk check could not be performed because exclusive access to the drive could not be obtained. Do you want this disk check to be scheduled the next time you restart the computer?" (I don't know why you would go through all of this if you didn't want to click ‘yes’ and why Microsoft held this over with 2000 and XP, but in their infinite wisdom they did! There may be good reasons to back down now but I can't think of any, so…)
Boldly click the Yes button! I guarantee it won't hurt a bit.
P.S: While in Safe Mode, you may want to run defragment as well.
