hey guys i have a 4gb sandisk cruzer usb thumb drive. I completely erased the drive, and then created a partition, and the partition comes out to 3.66 gb, not enough for lion. Any idea why its not allowing me to make the partition higher?

Thanks
 
It's probably due to the fact that there are two "gigabytes" in common use.

Drives are typically sold in decimal Gigabytes while the OS reports binary Gibibytes this leads to a ~7.2% reduction in apparent size.

see e.g. http://en.wikipedia.org/wiki/Gibibyte

Depending on the drive, there might also be a hidden partition for other purposes, e.g. many drives have a virtual CD partition for install software...
