Is my SONY USB flash drive dead?

Question

I have a following problem: when I plug-in my USB flash drive, it isn't shown in Windows Explorer or recognized by system at all. In device properties, it is shown as:

USB MEMORY BAR

There's no partitions on the drive, so I can't format it:

DISKPART:

Virtual Disk Service error: There is no media in the device.

HP USB format tool:

There is no media in the specified device.

Any help will be greatly appreciated! Thank You!

Answer 1

Sometimes it happens due to interrupted write or format operations. If file system is RAW then following won't work.

Try using diskpart. Open command prompt by start+r and type cmd. Follow this commands. It will ask for admin permission.

diskpart

list disk

select disk # (where # shows number of your usb disk)

format fs=ntfs quick
