How to Repair / Format a Corrupted USB Flash Drive or SD Card?

If your USB drive is corrupted due to a virus or an internal virus problem, then you cannot open the USB drive and you cannot format it.

How to format in the Cmd box?

If you want to format / reform it through a command prompt.

1: Go to Start and Find Command Prompt or type “cmd”

2: Right-click on “Command Box” and click “Run as Administrator”

Type “diskpart”

Type “List Drive” (you will see the total number of discs connected to your PC)

  1. Pick the right disk from the option and remember the total size of your disk. If you need to connect more than one disc, then remember your disk with their size.

In the Cmd box, select “1 disk” (disk 1 is my USB drive)

Type “clean” (you should try more than once until you clean the disc)

Create a partition of your USB drive.

Type “Create Partition” in the cmd box

Type “active”

Select “Partition 1”

Now you can format your USB drive

In the command box, type “format fs = fat32”

FS = File System

(fat32 = we will format the USB drive in FAT32 format)

All USB flash drives and SD cards were formatted via “fat32”

The system takes some time but after the format is complete your drive is ready to open.

  1. I know this if off topic but I’m looking into starting my own weblog and was wondering what all is needed to get setup? I’m assuming having a blog like yours would cost a pretty penny? I’m not very internet smart so I’m not 100 positive. Any recommendations or advice would be greatly appreciated. Many thanks
