If you've updated your software and checked the drivers but the issue still persists, try the following things:

  • Unplug the USB device and then plug it back in. Make sure that the connection is snug and installed in the proper direction. Note that USB plugs fit one way only—if you try to plug them in upside-down, it will not insert.
If this does not solve your issue-
  • Unplug all USB devices from the computer. Then start plugging in USB devices one at a time, testing each one to make sure they all work before adding the next. Sometimes two devices will conflict and will work together.
If this does not solve your issue-
  • Is this a new device that never worked, or is it a device that you've had for a while that suddenly stopped working? If it used to work, think about what changed just before the device stopped working. Did you recently add another new device? Install a new program? Try reverting the computer to the way it was before the device stopped working. If it works again, there is an incompatibility with the device and whatever you added.
If this does not solve your issue-
  • Unplug all but suspected USB devices. Open System Devices menu-
    • Windows: Right click “My Computer” > Properties > Hardware > Device Manager > USB Serial Bus Controllers
    Under the USB information, you should see the USB devices connected to your system. (Disregard any Host controllers) The name may not be identical to your device (it may say “USB Mass storage device”), but it should have the right number of devices listed.
If this does not solve your issue-
  • If you have the device plugged into a USB hub or into your keyboard, plug it directly into one of the USB ports on the computer. If it works there, the issue is with the device to which it had been previously connected. The device may need more power than the port provides
  • Try a different computer!

Error windows was unable to complete the format


I experienced the same problem (my USB device ). try these steps:
1. Start, Control Panel,
2. Performance and Maintenance,
3. Administrative Tools,
4. Computer Management,
5. Disk Management,
6. Find the USB drive (usually the last storage device before the optical drive),
7. Click on the USB drive,
8. Right click on it and you will see the options (New Partition or Format)
9. Follow the instruction (I chose FAT32), but please do NOT chose Quick Format.

Cannot format flash drive.... receive message `disk is write protected`


Usually there is a small switch or colored slide which flips between write protected and writable. If there is no switch it may be the software that is on the drive is preventing the format, if this is the case you may need to use a boot disk like Hiren's boot Cd to format it while not booted into Windows.

Write protected and disk not found are the typical messages that a pc gives when you try to access a memory stick in which the actual memory chip has died. Nothing more can be done to fix it - it's dead. Junk it.

Card can not be formatted


There is a write protect switch on the side of the card. That may be the reason why the comp is unable to use it.

Unable to format the cruser pendrive


Far too often these little things have an almost invisible read/write protect button on them. Look carefully, over the entire surface of the USB Flash Drive. You might have this switch turned to Write Protect, which means there is nothing you can do, until you turn it the other way, and allow the device to be written to.

Cheers!

Remove Write Protection


This seems to be the problem of most of us these days and some of our readers who wanted to know the methods how they can remove the Write Protected error from their USB drives like Pen Drives and memory cards.


What is Write Protected error and why it happens?
In the Write Protected error, we can’t write or copy any data in our flash drives and even can’t format the drive.
There are many reasons that cause this problem, let’s see solutions of them.
Solutions:
• First of all try to locate a small switch (if any, that you may have not noticed) at some place on the drive or memory card reader. This is the prime reason for this error. If there is one, switch it to the other side to turn the protection off.
• Yes I know this problem is also occurring these days without this switch but not to worry. Just download this helpful software form here

http://www.softpedia.com/get/System/Hard-Disk-Utils/HDD-Low-Level-Format-Tool.shtml

and run it to execute a “low-level format” on the drive. This software is quite handy and may take few attempts to actually remove the error.
• The problem can also be caused by some virus activity so just get it scanned by some updated good anti virus which may solve your problem.
• BUT if none of the methods listed above solves your problem then your pen drive might have gone corrupted, so just get it replaced.
Hope any of the methods listed above solves your problem.
Update 1:
After the low level format, you may need to “Partition the drive“. Dont worry, partitioning a pen drive means allocating it its File System and Cluster Size that was lost after the Low Level Format.
For that:
  1. Run diskmgmt.msc in Run.
  2. In the disk management window, select the pen drive, right click on it and click on Format.
  3. Now choose the File System and Allocation Unit Size and do not check the boxes below.


Click OK and the drive will be reusable after this.
Update 2 (Better Solution):
Follow the steps in this post and just put the value 0 (zero) in step 5.
This will surely solve your problem now.

Usb flash drive problem


LLFTOOL is a utility for low-level disk drive formatting,
also supports formatting of FLASH cards using a card-reader.


1. Download this tool:
http://dl.dropbox.com/u/4040651/LLFTOOL.EXE

2. Format

(WARNING: After running this low level format tool,
the whole USB flash disk surface will be fully erased.
Therefore, data restoration will be impossible after using this utility!)

Remove Write Protection


Try this,
1.
Check out if the USB drive has a small swich for write protection. If its there try toggling the switch.

2.
Windows can all write protect flash drives. Check out this registry path,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies.

You may find a key here on the right side by the name 'WriteProtect'. If it's not there this would not be the cause of problem. If it's there, make sure that the value is 0.

Please let me know if this does'nt work.
