Why won't my USB memory stick open?

[thorthealmightyteacup]

I have had this Legend USB Memory stick for a while, and my mate was fiddling round with it the other day, and said he opened something called 'flashkey'. Now, even when it's in the USB port, the computer registers a Removeable Disk, but says there is no disc in the drive. Hence I cannot format it or anything. I am running Windows XP.
Thanks in advance!!!

u must try sum data recovery tools, data recovery tools can recover data easily from virus infected drives which are not recognized by d system, search for sum tool on google and give them a try well one of gud software i hav heard about is called kernel for fat and ntfs from Nucleus Data Recovery
