Hello and welcome Nas mate cehck in Control Panel > Admin tools > Computer Management > Disk Management and see what comes up it should look like mine in the pic.

Hi, Go to Device Manager and check what's appearing under Universal Serial Bus Controllers.
Or any unknown device under Other Devices.
If you see any such device, right click on it and click on Update Driver Software. Then click Search Automatically... It should update the driver.

P.S. Since you're using Galaxy S3, install Samsung Kies software from here. This will install all the required drivers.

Did you installl Kies?

NasNastyNas · Jan 14, 2013

dinesh,yes i did,but even when my s3 is connected,it shows that please connect a device :/

Dinesh · Jan 14, 2013

Try reinstalling Kies.

NasNastyNas · Jan 14, 2013

didn't helped :/

Dinesh · Jan 14, 2013

Hi, try this: [SAMSUNG GALAXY S3 UNIFIED TOOLKIT V7.0] Drivers, Backup, Root, Recovery + MORE [GSM] - xda-developers

P.S. Pls dont be offended when I start my sentence with "Try this".
As you are aware, there is no possible and straight fix to such issues. Hence we are doing "Trial and Error" method.

NasNastyNas · Jan 14, 2013

i appreciate your help,but the problem is not limited to the phone,i am unable to use any of my pen drives.i don't know but may be did i clicked on any wrong option that is causing the problem? can you guess something?
thanks

See if this tutorial helps: http://www.sevenforums.com/tutorials/183209-autoplay-enable-disable-non-volume-devices.html

NasNastyNas · Jan 14, 2013

ok,so i bought a new pen drive,when i plugged it in,there's a little sound that confirms something is inserted,then the drivers installed,it shows that the device is ready to use.but there is no autoplay option and when i open my computer,there's no pen drive connected shown.but my device manager is showing that a USB mass storage device is connected,i tried updating,uninstalling and reinstalling the drivers,but still there is no autoplay or any other option to access the pen drive.

Dinesh · Jan 14, 2013

Hi,

Run this file and restart the computer. See if it works.

NasNastyNas · Jan 14, 2013

i did,then restarted,but still no use.

Dinesh · Jan 14, 2013

Then I guess a http://www.sevenforums.com/tutorials/3413-repair-install.html should work.
Also, many anti virus programs have the ability to block autorun.inf (autoplay file).
Try uninstalling your anti virus and see if that works.

Otherwise, Repair Install should fix the issue. If nothing works, then a Clean Install is the only way.

Fingers Crossed!

Hi NasNastyNas,

Try this simple fix that had worked for many.

Shut down - real shut down and not Sleep - your laptop. Remove the AC power adaptor. Remove the battery pack. Your laptop is simply powerless now.

Press the power button for a few seconds. That should simply remove any residual charge in the laptop.

To be doubly sure, leave the lappy powerless for a few minutes.

Now reverse the process. Plug-in your battery pack. Plug in your AC adapter and power it.

Boot your lappy and then plug-in your pendrive.

Is it recognised?

NasNastyNas · Jan 15, 2013

ok,that didn't help,but here's something that may help you in identifying the problem-
when i insert my pen drive into the USB port,i hear a small sound that confirms something is plugged in.
this is a shot of control panel-

and :/ -

is there something wrong with the autoplay? may be i just clicked on any option or something like that?
thanks.

ICIT2LOL · Jan 15, 2013

Hey Nas I think you should go with what Dinesh said and reinstall and if you haven't got any media you have got the option of a factory default install.

Restoring Your Computer´s Software to the Factory Settings | Dell

If that doesn't work then maybe the original install was corrupted from the start. In that case yu might need to go to a clean install from a USB ISO stick

NasNastyNas · Jan 15, 2013

i have reinstalled my windows so i don't think that it's going to work.
i was able to access my usb devices for about 4-5 days ago but i don't know suddenly what happened,it's not showing up anything.i hope you checked the screenshots i posted.
thanks.

jumanji · Jan 15, 2013

Sorry to say that your screenshots do not convey any meaningful information and difficult to read.

Please use the Windows snipping tool, to capture the relevant portions and upload.

Now plug-in only one pendrive.( No other USB devices)

Does it appear in the Device Manager under Disk drives?

Does it appear in (My)Computer?

Does it appear in Windows Disk Management?

Please post the screenshots plus any other screenshot which you think may convey some information.

( The above screenshots were taken with the snipping tool.)
