This can happen if you remove the device or disc before all files have been written to it.If you close the popup or select "Continue without scanning", then this popup will continue to haunt you until you decided to click the recommended Scan and Fix option. There are guides on how to disable the scan and fix window by disabling the Shell Hardware Detection service but that really isn't a viable solution since you're telling Windows to ignore the problem rather than fixing the problem itself.There is a tool called fsutil.exe in Windows which can be used to check if a volume is dirty and can even be used to manually set a drive as dirty which will force the requests to scan it, but weirdly it cannot be used to clear the dirty bit. Someone has already reverse engineered the fsutil.exe to confirm it.So there seems to be 2 solutions to clear the dirty bit which is to trust the Microsoft disk checking utility by completing a check

So I was copying over some movies from my laptop onto my new 1TB external hard drive, was working fine and managed to copy over a fair amount, then all of a sudden the ones that were currently copying failed, so I took http://www.sevenforums.com/hardware-devices/256903-hard-drive-error-volume-dirty-0x80071ac3.html out the hard drive and plugged it back in. Now it says I dont have access to it? Iv tried the Chkdsk B thing but to no avail. Any help much appreciated, I dont mind losing the movies that are already copied onto the External HDD I just want it back in working order (or will it just keep happening i.e. faulty HDD?) Thankyou in advance guys!

Sometimes when a drive is disconnected without safely removing a file becomes corrupted and Windows flags the drive as "unreliable" (so to speak) by setting a single hex value for the drive as "dirty". Thus "the dirty bit". To check if this is so, open an elevated Command Prompt and then type " fsutil dirty query m: " (with m being the drive letter for the external drive. This will tell you if the drive is marked dirty. If it is, then do this: open the Command Prompt and type: " CHKNTFS /X m: " . This will te
Turning off your computer improperly can leave the dirty flag set. by Leo A. Notenboom, © 2009 During a chkdsk scan, the system was characterized as "dirty". What does that imply? • For the record, it has nothing at all to do with porn. But it http://ask-leo.com/chkdsk_said_my_system_was_dirty_what_does_dirty_mean.html does have everything to do with how Windows manages your hard disk, how it optimizes reading and http://askubuntu.com/questions/112150/how-to-correctly-fix-a-dirty-ntfs-partition-without-using-chkdsk particularly writing to the disk, and how you turn off your computer. Yes, the most common reason for a dirty hard drive is turning off your system the wrong way. • To oversimplify, the concept is very simple, Windows sets a "dirty" flag on your hard drive whenever it has unfinished business with the drive. One example of "unfinished business" is that Windows can optimize disk access by disk error buffering data to be written so that it can be written in a single, larger operation, rather than a number of smaller ones. While the data has been collected, but before it's completely written to disk, the disk is considered "dirty" - not all the data that should be written to the disk has been. Once all the data has been actually, physically placed on the hard disk, the disk might be considered "clean". "... Windows sets a 'dirty' flag on your hard drive disk error windows whenever it has unfinished business with the drive." This kind of halfway state, with data only partially written on the hard disk, is actually common, and programs running on the system - and even large parts of Windows itself - are completely unaware that this is happening. They hand off data to the disk management system to be written, and simply assume that it will be, in some kind of timely fashion. (Optimizing disk access while maintaining data integrity and system speed is actually a very complex topic and the subject of a lot of system design effort. How data eventually makes it to the disk and in what order can be thought of as so much black magic these days.) So why is all of this important? Well, consider this: you perform a "Save As..." in your favorite word processing program to save a copy of your document under a new name. Until both all of the file's data, and its entry in the filesystem's list of files or "directory" are physically on the disk, the filesystem could be considered dirty. What happens if the power goes out halfway through writing the file? Your machine has been shut down with a dirty file system. Typically, that means on reboot CHKDSK will be run automatically to check for and repair any errors on the disk. And it also means you might lose the file you were writing at the time the power went out. Now, losing power in the middle of ed
