Hello there yogeshpat876.

Here's your geek-steer ...

Is this a new drive? If so, it probably just needs to be formatted [and optionally assigned to whatever free drive (letter) you desire]:

Start > Run... > tpye "diskmgmt.msc" (without quotes), then OK

Good luck, and please do post back ...

• to let me (and interested others) know how things worked out,
• to provide clarification or feedback,
• if you have ANY further questions.

Today's the best day of my life ... and NOW you're part of it!

I would first put it through a fast formatte then a standard formatte, then i would recommend asector scan and see if there are any sectors that are not recoverable, if they are messed up and or still not solved try to uninstall the file that has stored the recognition files for the pen drive remove the main file in c drive program files , find the file by name corresponding to what it is you have and delet it then do a full shutdown and after a full cold start reboot install pen and software when asked if you still experience this post the results and i will try to help in a higher level of tech knowledge and support

i had purchased a pen drive of Moser Baer AZ-601USB device. previously it was working good, but since last 3 days i could not open my pen drive..it asks for formattin. i have formatted it , but after that it says your pen drive is write protected. so i could not open and use my pen drive....

so plz solve my problem to open my pen drive.

How are you formatting it? NTFS or FA32?

I suggest you reformat as FAT32

opening pen drive, it shows 'please insert the disk' & it shows 0 bytes & while trying to format it shows the same message again , i am using 2 gb pendrive of trancend.
