I want to try to format my pendrive but it show the error as

Device Boot Start End Sectors Size Id Type /dev/sdc1 2048 7802879 7800832 3.7G 83 Linux

Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

when i try it from GUI

Error formating volume

The size of pendrive is 4 GB but when i see it in file browser it shows the size 69 GB, why?

enter image description here

How can i format this pendrive in Fat or NTFS format?

Your pendrive have an error, so we have to fix that first!

Open a Terminal and type:

sudo fdisk -l

to find out your pendrives name. Then:

sudo dd if=/dev/zero of=/dev/sdx bs=512 count=16

where the x is the letter of your pendrive! Type in your password and hit enter! This fixes the wrong header entry on the pendrive, by overwriting any and all with zerroes, in the first 8 KB!

After that you can use your normal partition program: Set to Dos and make NTFS or Fat32 partition for compatibility with other computers and multimedia equipment!
