Windows 7: Hard Drive Error: Volume is dirty 0x80071AC3

14 Oct 2012   #11

64 bit

Hi Jumanji, when I try to format the disk via the HP tool it says the device is 'write protected'. How do I get around this?

Will attempt a format tomorrow

This is a last-ditch effort to get your drive initialised to the factory condition.

Download the Windows executable (works without installation) HDD Low-level Format Tool from HDDGURU: HDD LLF Low Level Format Tool

Right click on it, Run as administrator and try to low-level format the correct external drive.

The program will start writing zeros to each and every sector and reinitialise the hard disk to the factory condition (it will take a considerable amount of time since yours is a 2TB drive. So be patient.)

If it succeeds you need to format the drive using the usual format tools.

If it does not, and spits out an error message I will throw in the towel and RMA it.( unless someone else comes up with a resolution or a fix. It may well be a faulty electronics/controller in the drive.)

Windows 7
Hard Drive Error 0x80071AC3 Volume Dirty [SOLVED]

I finally found a solution for this here:

If this doesn't work you basically need a new hard drive.

EDIT: sorry for bringing the back from the dead.

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 tell Windows NOT to check the drive on the next restart. Then manually restart the computer (keep the external connected).

You should get into Windows without an messages about the drive.

Once in Windows, now run chkdsk on the drive. At the Command Prompt type: " Chkdsk /f /r m: " . Chkdsk should go through all 5 stages of it's test.

When it's done then check the disk by running " fsutil dirty query m: " again. If all went well the Windows will confirm that the dirty bit is not set on that drive.

Sometimes chkdsk can not reset the bit. In than case you can go nuclear and copy all the files off the drive and then format it (that will definitely reset the bit).
Or you can do something like this with a Hex Editor: Manually Reset or Clear Dirty Bit in Windows without CHKDSK

I hope that helps. All this was based on your post title!

Didn't want to reboot yet. So tried "chkdsk /r m:" without running "CHKNTFS /X m:" and without the reboot. It worked, the dirty bit is fixed even though chkdsk did not show any issue. Note that /f was not required as there was no issue found. Note also that "chkdsk m:" did not do the trick.

It Depends On How I Feel That DAY 64 bit

I'm copying from a 4TB external hdd to a 64gb exFAT micro sd and it wont let me copy more than about 500mb and it'll pop up with this error. I've done it 10 times now. restart chkdsk /f /r g: afterwards. Every time starts off copying, then goes dirty. What can I do?
