Write protect not format - HP P Fd16ghp220 Ef v220w Usb Flash Drive 16 Gb Thin Metal Design Store

Slide the write protect tab forward to remove the write protection. You cannot format it while it is write protected. Formatting will erase all data on the card. Install the card into a Windows or MAC and wait for the device to detect and mount the card. Use the appropriate procedure for the machine to format the card. See this procedure for additional step-by-step operations after the write protect tab has been moved.

it might be helpful to you.

Note: Some "pen drives" have a write protection small switch on the side of them. Please confirm if this switch (if present) is not in the write protected position.

Some usb pen drives,  if thats what you mean? They have a little button on the side of them to protect the contents of the usb pen drive. Check that, tyhen go to "My Computer" look for pen drive, Right click and format.

 Best of luck.....

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!

try this tool HP USB Disk Storage Format Tool!!

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.

if u format ur pen drive. then use this step
-
Check out the registry under:

1)click on start button
2)clik on run dialog box
3)type regedit
4) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies.
The value 'WriteProtect' should be absent or set to '0' and when you try to format it you have to format it as FAT16

Good Luck!!

Remove Jet Flash Write Protection Insert the mini CD that came with the USB Flash disk. Start JF Utility.exe in the JF Utility directory. If it complains that the disk is write protected, choose "Continue" Choose "Partition" Answer "Yes" to losing all your data (Since this becomes a problem usually after formating the disk in WinXP or Win9x, you will most probably not have any data on there in any case) Choose "Public Area Only (Single Partition)", Then "OK", Then "OK" again. Unplug the device, reinsert device, and voila!- no more dark secret areas or write protection on your disk!

the drive isnt write protected the usbport or the connection is loose so that the computer is showing the drive as read only drive also you can format it using command and also setting off the read only attribute that may have been put by a virus also softwares like usbcillin makes pen drive writeprotected take care
