I recently ran the windows XP disk checking utility on an 120GB Maxtor external USB HDD.  I selected both the "automatically fix file system errors" and the "scan for and attempt recovery of bad sectors".  I epxected it might take a while to run, however, it has now been running for a week and still isn't finished.  It is still running task 4 of 5 and has found some bad clusters, there are about 25 files listed that have had portions of them replaced.  My issue is that it has tied up my computer for a week now and I need to use it.  How can I safely stop the check disk without trashing all the data on the drive?

I ran it from the Windows OS which then requires a restart before the utility runs.  It actually runs before the OS loads which is why I can't figure out how to terminate it.

I don't think there is a way around this.
I would not recommend but would do if i was you is pull the pwer.

It is only a chkdsk at the end of the day. It'ss only checking one file at a time, not editting them.
nothing bad should happen. i'm 99% sure your be fine.

My laptop does this all the time because it's old and dieing. I pull the power and skip on next boot.
everything always works.  IT's up to you :)

Sorry I can't help more.

There is an outside chance that CHKDSK running like this (i.e. with the /F & /R switches) could be editing a cluster when you pull the power - unfortunately I guess this is a risk you are going to have to take and TBH if the scan is taking that long (and you don't have a TB sized drive) then there are clearly errors on the drive anyway.

It's highly likely that the remainder of your data will be safe and recoverable even if you are unlucky enough to have damage to the disk integrity.

I would suggest that you unplug the power to actually stop it.  I would highly recommend that you rebuild the system from scratch...do you have your data backed up offline?  

This usually means you have added and removed so much stuff the system is having issues recording the table for the records properly.  You may not have enough disk space for the system to do this correctly also.

To answer your key question...there is no "safe" way to stop the process.  You may cause other files to become corrupt.  I would also suggest installing Diskeeper (or similar if you prefer) and have it run in the background with your new install.  This way the need to defrag will be eliminated.
