Scan And Attempt Error Correction on USB Drive

Hello, I have a USB drive attached to my win7 tablet and need a free utility to run a disk check with error correction on it. The built in application in win7 won't touch and it does not try and scan upon boot as I've seen happen in the past with other drives.
Any recommendations will be greatly appreciated.
Thanks,

J

Why does it not run? Does it say the disk is busy?

If so , you could boot to safe-mode and run the check from there. nothing should make the USB drive busy there.

Else you I would recommend you chkdsk from a WinPE CD/USB.

In Windows 7 press Start - type in search pane CMD - right click - run as Admin.
There type CHKDSK x:/f/r where X: is a drive letter of your USB drive.
If you do not have files opened from this drive - it must run in Windows without restart.
No other tool will give you better results on FS check than MS CHKDSK.
If you are concerned on HDD surface problems then you need to take drive drive out of enclosure, connect it directly to your machine and run the check of it this way.

You get the message: "Windows cant check the disc while its in use...Do you want to dismount this volume first..."
Click: "cancel" then you will get the message: "Windows cant check the disc while its in use...Do you want to check for hard disc errors the next time you start you computer"
Click: "Schedule disc check"
Reboot your computer and the disc check will start.

It should not take a couple of hours.
You hard drive may be bad, check it with HDD diagnostics:
Check your drives condition with:
Download Limited Trial / Free Versions

Or
Here is a link to most HDD makers Hard Drive Diagnostics Tools and Utilities

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

It should take so long. Let it run. Don't forget that you run both F and R commands. So it is testing the file system and HDD surface at the same time. Let it run.

thez time it takes depends on the disk size, and it's occupation.
a 1 TB drive takes a "tad" longer than a 80 Gb drive..

I did not make my comment clear:
It should not take a couple of hours to reach this stage
"CHKDSK is verifying file data (stage 4 of 5)...
11 percent complete. (19 of 81904 files processed)"
My 300GB HDD which is full of data gets to stags 4 in a few minutes.
After that stage 4 processes files slowly (about 1 per second)

Did you mean by  "it has been on the spot for 2 hours, is this normal?"
At " (19 of 81904 files processed)"???
If stuck at 19 this may indicate a hard drive problem.

Michael, don't forget - this is USB drive not internal one. So must be a bit slower. But still, he is using /R command, it is always slow.

My comment was for a 300GB external USB drive as I too was wanting to know how long it took using Windows 7, so I ran the command  CHKDSK G:/f/r on my disc to have first hand knowledge.
To the start of stage 4 took 3 minutes.
To the end of stage 5 took 5 hrs.
8675309jm file count shows 81904 files so I guess about 8-12 hrs but depending on CPU / memory and hard disc size it may take alot longer.
Also to exit the scan when completed you need to type: exit then hit the enter key.

Before you get help by data recovery company, take the drive out of enclosure (they will do the same btw) and connect it internally to free SATA port on your mobo.
Then try to run on it GetDataBack software from here: www.runtime.org
You risk nothing doing this. And if it does not help - then call data recovery guys.

Did you test your drives condition as I suggested: 23/02/11 04:39 AM, ID: 34954897  what results were given?
What size / format is your drive / data?
Is the drive making clicking / rasping noises?
How much are you willing to spend on recovery?

There are many data recovery programs out there, but if you must recover data then the less time stessing HDD will give best results. If you choose to try the free software you may be lucky or you may just overstress HDD and reduce you chances. (best, do it once, do it right)
(Compessed zip,rar,(MP3,AVI) files may never be recoverable.)

If your data is very important, then if you willing to spend $$$ try :
http://www.recovery-experts.com/
(No Data; No charge policy)

Otherwise:
Download and install "Get Data Back" NTSC or FAT depending on the file system of the lost data:
http://www.runtime.org/
It is free to use to find your data then you can buy it to recover the data.
