I am running Win XP. Every time I boot I get a message that one of my disks needs to be checked for consistency.
I have deffagged but didn't help.
How can I stop this irritating thing?1ets...Have you tried running a diskscan?

dl65 How was the pc shutdown.............did you turn it off.....or did the pc reboot itself.?Possibly caused by DATA corruption, so run a check on your RAM and run the drive manufacturer's drive-diagnostic DISKETTE over the drive FIRST of all to see if there are any errors.

If all is clear, and you may have to re-seat the RAM modules and make sure that the IDE cables are WELL plugged in, run - chkdsk /r - after backing up any vital data.

XP INFO
If you have run SFC /SCANBOOT you need to type SFC /REVERT in the Run window to stop it checking every time you re-boot, btw.I ran chkdsk and defragged.

Screen appears everytime I boot regardless of shutdown.Take a look at this Registry key...

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager

Then at - BootExecute REG_MULTI_SZ

The value data should read...

AUTOCHECK autochk *

(These is a gap between the k and the *)
