Disk Unsueable and Unavailable - Sony Media USB Device

After I opened the flash disk and tried to open the file or folder. It said that " Please insert a disk into Removeable Disk (H:). "

Clean command doesn't work, format either

Then, I check it [again] in dispart ...

Tadaaa, there's " * " mark on it. I've read some article, it said that it's already selected

list disk with " * " mark

from healthy disk become unuseable disk

[There's should be 4 picture on it, lack of 10 reputation #sigh It's not mine, but my friends Limit of tag that need 300 reputation #sigh]
