My pendrive conected to the

What Operating System are you using now? Try looking your pendrive in the Disk Management.

Go to Start, Control Panel-> Performance and Maintenance->Administrative Tools. Double click Computer Management icon -> Expand Storage, click Disk Management. Find on the right corner bottom if the removable disk is detected. If it does, Click Make Partition as Active / Reformat.

*Drop me a comment if it is detected or not. I'll be waiting. I will assist you.

'd also suggest that you download and install all available Windows Updtaes, if you haven't done so already, and also download and install any available motherboard chipset drivers for your system or motherboard.
Also try to connect the pen drive to the USB slots at the back of your computer...

Some of the Windows updates correct USB problems......

If this does't help, you can for sure correct this problem by troubleshooting procedures as given in the following website:

Your USB drive has an internal failure making it unrecoverable. I am most convinced of this since Linux could not detect it. A pendrive is a handy little thing, but you should make a habit of backing up your files on another medium. Hindsight is still 20/20. And while HP may replace the drive, they will not recover your files for you. Sorry.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
