Having problems with a USB flash drive

I have a "Adata" 1GB flash drive .. that i bought a year ago ... that worked fine till a couple of days ago ... now i`m having serious and annoying ishuess with it ...

When ever i plug it into the PC .. it automatically detects it as normal ... but when i try to access it it says .. that the drive is un accessable and needs formating, when i "right-click" and check its properties in MyComp ... it says that the drive has 0 bytes space on it .. and 0 bytes used *o_O*. Ok .. since the data on the drive wasn't that important to me .. but the drive itself i went ahead and format the drive, now it shows me the correct values when i check its properties ... and i can use it normally to store data on it .. but if i unplug it .. and plug it again .. the drives goes to the "Drive unaccesable .. needs format" etc etc.

A friend of mine who has a tad more knowledge in the matter than myself said that the drive's boot sector is damaged and that i should seek out some kind of software to repair this. Since then i tried a gazzilion types of programs & software .. but i still didn't managed to fix it. I`m thinking my problem is that i don't properly understand how a freaking flash drive works .

Can someone here explain any solutions as to how i can fix my problem ? how to recreate the boot sector on the drive ? how to define its filesystem ?

If u think u can help me please get in contact with me over email ...

If the OS is Windows, you are probably removing the drive without first stopping it via the "safely remove hardware" command.

Does the unit work on another system? How old is the unit?
Flash memory has a finite limit on the number of read/write cycles.
They do wear out.
