I have a 8gb pen drive of kingsten dti series it works perfectly but today my antivirus shows a virus in it and when i try to format my pen drive it shows an error of write protection and after that it...

I am sorry to hear that your USB pen drive got a virus. If the message you get when you are cleaning or reformatting the drive is password protected, the drive is very much finish. I would suggest you to buy a new one.

My pen drive with usb 2.0 drivers is not opening........and itr says aceess denied everytime i try to open it please help me

click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you should see a yellow question mark?
right click to reinstall drivers
if you can see your usb drive but its not working
ports(com&lpt)right click update driver
click start click on my computer you should see your pen drive
right click then select format
another way is to control panel administrive tools computer management disk management right click on your drive select format

USB drives can be write-protected by modifying the StoreageDevicePolicies Registry key and WriteProtect Registry value.
click Start>run>regedit to open Registry Editor. and press control+F to open the find dialogue box and type "usb device" or "driverdesc" to open usb mass storage device or type "usb mass storage device" in the search windows. And right click on it and delete. This will set the policy value to 0. then insert your usb device. It will work fine.
# Remember: do not delete any unknow files in the registry as this will make some programes not work as usual.

If you are running a Windows XP OS then you might be able to:

- click start right click on my computer select open
- Right click the icon of your Flash Drive (It should be F:/ or something)
- Click Properties in the menu that comes up
- Click the Sharing tab
- Click permissions
- And finally, click Allow next to Full Control.
hope this helps

When i an entering data in pen drive after that when i am removing pendrive form pc, after that i can not see any data in pen drive, please informe me early as posible

If you are not dismounting your pen drive before removing it, you run the risk of wiping out the contents of the pen drive. You didn't mention that you were dismounting it before removing it, which is why I suggest that this may be the problem. The way to properly dismount a drive or any other USB device is to go to the lower right hand corner of the PC screen and look at all of the icons for the one that says "Safely Remove Hardware", click it and then follow the instructions. Under Windows Vista, the Icon has a small white checkmark in a green circle, but other versions of Windows may have a different icon.

Hellow sir, I am mahesh. I have transcend 4GB pen drive (JF V10). My problem is, When i connected pen drive to my pc then it could not start but it was shown in my computer as a removable disk and...

its just simple MAHESH...

1st if your pen drive has no data inside.. don't hesitate to reformat it.. then try again..

2nd check the device manager on your computer if the pen drive of yours was updated with its USB port.. just look for the UNKNOWN DEVICE in the USB port in the bottom of the device manager..

if there's no name of UNKNOWN DEVICE it means you must go to the settings of your pen drive..

just right click your pen drive then properties,, then look for the AUTO PLAY then select the action to perform..

then apply and ok... now close all documents then go to my computer and right click your pen drive and click the AUTO PLAY if its work... restart your pc... then its done... ^_^

please check the device manager if USB is enabled there
to go to device manager
start menu > run > type in without quotes"devmgmt.msc" > the device manager look for usb (universal serial bus controllers)

if they are ok ( there shouldn't be any exlamation sign next to any usb device check expanding the title for universal searil bus controller)
neither they should be disabled no cross should be there next to them

then go to computer management by going to

start menu > rin > type in without quotes 'compmgmt.msc' >
removable storage > right click > properties > security > use, control, modify should be allowed for your user name

if this is also right click on disk management in same window and then insert the usb drive in check if it detects and show here, if it shows format the drive as fat

and now when you insert it the next time it will show automatically

if any of the above doesn't work

restart the system and then press F2 /delete key (whichever applicable in your case) to enter bios at mercury logo and check here if usb is enabled or not. if disabled enable it and follow the above steps again.

Further Queries are welcome

USB Connections

when you put a device on the usb slot the system will detect and check what is the device then after it identifies the device it will load the necessary drivers for it. it is possible that the system is loading a corrupt driver to drive the usb device resulting to a system halt. it could be a driver related in storage devices such as thumb drives that is causing the problem.

try to update the usb drivers using the update driver option on your device manager on usb controller.

Usb problem

You shouldn't need the USB driver 2.0 from mercury because windows installs this with SP2. Suggest you un-install what you installed from mercury & update your version of windows (completley), through "Windows Update". Once windows is all updated & you have finished with a reboot. Plug your pen drive in a opened usb port. Open windows explorer. Scroll down & you should see an icon (left side of explorer), thats named like, Removable Disk. Give windows time to see the device. After a few minutes if your pen device does not show up try another usb port. One you know does work. If after a couple of minutes go by & you still don't see the device listed in explorer I would say the device is defective. Your Mp4 uses a cable to connect to the usb. Try connecting to another PC's usb port. It is possible the cable is dirty or bad.
