My name is Manoj.
I have a 16 GB sony pendrive. When I plugged it, it shows 12 GB of it is filled. But there where no files in it. I tried even unchecking hide system files in folder options. Then I found a folder named FOUND.000 which contains FILE000.CHK to FILE312.CHK which constitutes 12 GB of memory. I am unable to delete them even in cmd diskpart. Whenever I try to format or access the pendrive, it changes from state 1 to state 2 shown in pics.. Pls help to recover my pendrive.
