windows 7 - Can’t access USB flash drive anymore

I have a 32 GB Lacie Cookey USB flash disk that doesn't show in the Computer window but it's visible as a device.

cmd > diskpart

DISKPART> list disk

  Disk ###  Status         Size
  --------  -------------  ------
  Disk 0    Online          149 G
  Disk 1    No Media          0

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> clean

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

It also appears in the Disk Management tool, but the box is empty.

Is there anything I can do or is it dead?
