look for a slider on the side of the pendrive that unlocks or locks it
Gary CaseRetiredCommented:
There's most likely a write protection value set in the registry.

Follow the instructions in the PDF file I've attached.

Is there a switch on the pendrive, with the lock unlock symbol this can couse  the issue?
Here you have 2 USB format tools:

HP USB Disk Storage Format Tool 2.2.3

Hello there is no switch it is a simple 8 gb plug and play usb pen drive of kingston company. I have already tried registry option cannot find out the storage policies in my windows 8.1 OS. I have one more laptop but it has windows 8 non genuine OS.
Davy ParidaensCommented:
Execute in cmd the following (as administrator):
1. diskpart
2. list disk (dis will show the active disks)
3. select disk3 (this as example you will us the number that indicates the USB pendrive)
4.attributes disk clear readonly

Did you test HP USB Disk Storage Format Tool 2.2.3 or Swissknife?
ITISEMEAAuthor Commented:
Davy I have mentioned in starting that have tried these attempts of attribute clear, the HP and Swiss Knife are not for 8.1 windows OS.
Gary CaseRetiredCommented:
Try this:  Go to Device Manager;  expand disk drives; then right-click on the USB flash drive and select Properties.

On the Policies tab, check "Better performance"  (by default it's most likely on Quick removal).

Now close Device Manager;  then do a "Safely Remove" the flash drive;   then plug it back in ... and then try to format it.

[This works in most cases on '7 -- not sure if it's equally true with 8.1]

Is there a partition on the pen drive to which you can copy files and read them?
It could be that the pen drive itself is bad and Windows formatting tool is reporting the wrong error as it does not get to partition structure of the drive.
Try to wipe the pen drive using DBAN.
Thats symptom sometime mean that USB drive has malfunction. Twice I bought a new USB flash drive and could not use all of it's capacity, let's sey I could use only 1GB, after that I would receive message, disk is write protected.
After you try recommendations you already got, try to make a quick format, if that goes well, almost certainly your USB drive is bad.
Try to format your USB drive on some other computer to eliminate Windows error.

Nothing goes well have tried everything; there are no partitions, earlier the drive was good past a year.
No partitions?
Is drive exists in disk manager
should be there as disk 1, 2, 3 or similar
ITISEMEAAuthor Commented:
Yes it is Disk 1 when i was doing command prompt remove of attribute, i used to select disk 1 showing 7xxx mb of the data. I meant i did not create any partitions inside pen drive or usb drive.
Open Command Prompt.

select disk 1
create partition primary

that should create partition

if partition is successfully created
you can type

format quick

to format partition from cmd

The drive is bad. It still can show its presence and size but nothing else. Replace it.
ITISEMEAAuthor Commented:
so no solution is there i have already done in starting all the troubleshootings; even i can post answer:-

No usable free extent could be found. It may be that there is insufficient
free space to create a partition at the specified size and offset. Specify
different size and offset values or don't specify either to create the
maximum sized partition. It may be that the disk is partitioned using the MBR di
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).
