Pen drive display free space 0 byte and used space also 0 byte

Hi Virus or Trojans can run some process that keeps running in background. This not only harms the computer, but also prevents the pen drive from formatting as it shows that the drive is in use. Remove and re-insert the pen drive, don't double click on drive and cancel autorun operations if it starts automatically. Run a virus scan on pen drive, this will help fix the issue. Now format the pen drive.

Do not use any more and get some data recovery freeware.

There are two possible
1. Damage to partition table
2. Damage to firmware

To fix the Transcend flash drive, you can use the JetFlash Online Recovery software, customer support from Transcend. This program can be used to save data, repair damaged partition table and damaged firmware.

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

How are you formatting it? NTFS or FA32?

I suggest you reformat as FAT32
