Why is the file system on my USB pen drive not recognized?

Bakhtier asks:

I have USB pen drive Silicon power 4 GB. Recently, I had a problem with it. When I plug it in, it showed that software is installing. On my computer it displayed as removable drive, but by double clicking I get a message insert a drive and properties showed that it is unrecognized file system and with 0 bytes data. How can I restore my pen drive?

Make sure that the lock/unlock switch (if present) is set to the unlock position

The best will be to format it again, choose FAT32 system file.

Once/before it’s formatted, you can try some data recovery tools to try and recover any data you had on it.

One more point, I can’t format it! It just says please insert drive.

Hope that your usb key is not broken one.

Have you tried your usb key in another pc, if there works then just format it and ty it again on your pc.

USB port may stop working after you remove or insert a USB device

you should try shutting down the computer and literally disconnecting the powercord from the powersupply then reconnect after a few minutes and start up the computer again!

I have tried in another PC, and in Mac as well. No result. I couldn’t wait till everyone writes me a solution. I went to IT guy, and he restored my USB drive. Now it works. I lost all the data. I don’t know what he did. But as soon as I will get the info. I will let know everyone.

Thank you for the feedback, Bakhtier! Looking forward to hearing what the IT wiz did with your flash drive to fix it. :)
