Computer checks disk E on every re-boot

I have a home built PC- Win XP Home SP3, 2.8 Pentium Northwood, 2 hard drives, 2GB RAM.
Recently it insists that drive 'E' needs to be checked for consistency on each re-boot. It never finds any problem and the computer runs fine after. E is a 300GB drive for data only. I have C (operating system) and D (programs) on a separate disk. I have run chkdsk /r and Maxtor diagnostics and all report fine. I checked power and data cables and all fine. Eventually I cloned the hard drive to a new 300GB hard drive and then relaced this in the machine with an independent power supply. Same problem - it wants to check this new disk for consistency each re-boot. The machine runs fine otherwise and all data on E is available. Can't resolve this annoyance. Help appreciated. Thanks.

GO to my computer, right click on E, then properties, then tools-> scan  and check "Automatically fix errors", if you are prompted to restart then click no
What you're experiencing right now is an error check that Windows runs at startup.  It looks for a "dirty bit" and if the dirty bit is set  a program called "autochk" runs which automatically performs CHKDSK /f.

To fix this problem you should go to Start -> Run -> "cmd"

In the command prompt type in "fsutil dirty query E:"
This checks to see if the drive is dirty or not.

Next type in "CHKNTFS /X E:"  <- This tells Windows not to check the drive at the next startup.

Reboot the computer and do a manual CHKDSK by typing "Chkdsk /f /r E:"  This will do a full check up and remove the dirty bit

Then type in "fsutil dirty query E:" to confirm that the drive is no longer dirty and you should be set.
