I used one pen drive. It is Trans-stack Pen drive and its memory is 4BG. I normally used every time. I bought it on two years. and used every time in full memory. But now I find 2GB. when i send some file over of 2GB then it was hang. I do not know why it hang this moment. but if I used 2GB memory then i can't face any problem. Why it see this problem and what its solution.
This must be because of virus attack on your pen drive or on your computer. Therfore, I advise you to scan with a new antivirus and heal your computer before it destoys all your files too. And it is not the problem, then please format your pen drive. Go to My Computer , then right click on the pen drive, then click format your pen drive, a prompt box will appear, click to fast format and click ok, and please check whether it is in fat32 file system or not. If it is in NTFS file system , then change it to FAT32 file system and then click ok. to format. please Note "Formatting will erase all the files on the pen drive device". Please do the back up before you format it. After you format it, it 'll show 4GB again. You can use it to full space again.
Hope it has helped your query.
Thanks.
This issue is not actually the Pen Drive capacity nor virus infections. I have not encountered any virus infection that reduces the capacity of a pen drive. I have only encounter with synonymous effect but it will fully emptied the capacity of the pen drive. The virus generates a hidden file in an specified folder to use the available space in your pen drive.
Your pen drive might be a clone or it is made in china. There are so many imitations today which are usually made in china. The packaging says 8GB but on actual, the memory capacity is just 6GB and if you full the capacity the flash drive hangs-up or get corrupted. So beware of these imitations or clone pen drives.
