Flash drive maps as removable disk

A flash drive is a removable disk, but that shouldn't stop you accessing it. What do you expect it to appear as?

sarcasm is not an answer. flash drive will have to be reformatted.

There was no sarcasm intended in my reply. You can remove a flash drive, hence it is a removable disk as far as Windows is concerned.

You should be able to format it just like any other disk, but some flash drives have switches to make them read only.

I'm sorry if I misunderstood your post, but you seemed to think the fact that it was showing as a "removable disk" was the problem. People give their time freely on these forums in an attempt to help others, so it's not very constructive to be rude in reply.
