4GB USB drive shows only 64MB. Any idea how to fix?

Hope this is the right forum for this topic
any way
I got a Sandisk Cruzer palladium 4 gb usb drive. I gave it to a friend and after getting back it shows only 64mb of space, and it cannot be formatted and cant be opened as well.
IN disk management the partition option is disabled. ANd it was a u3 cruzer drive but now the software cant be installed on it.
I have also tried Hp usb disk format tool but that still doesnt format the drive
One more thing is that the usb light is not on continuously, it keeps on blinking.

Any ideas how to fix the usb drive?
 
A couple things:

Sandisk Cruzers are often faked. Its possible yours is, especially if you ordered it real cheap from somewhere online or ebay. There are a few websites that can help you identify if its genuine or not.

HP Format tool usually fixes these type of problems. So since it didn't the drive simply may have died.

If you have a virtual machine with 9x on it, or access to a machine running 9x, try formatting it with that machine. I don't know exactly why that brings some drives back to life, but several years ago when people were dual booting XP and 98 I saw a couple unformattable (in XP) drives get fixed by formatting in 98. I've never tried it, but whatever 98 does differently might be similar in Linux, so you could try booting off a live linux disk and formatting it that way - I have never seen this work, but I've also never seen it attempted. Both of those suggestions are kind of a long shot though and I wouldn't get your hopes up too much.
 
thanks 4 replying. but is there any other way except formatting on windows 98? like any software or something like that which can be done through xp?
