Many of my friend's often ask me about some tip in buying second hand USBs. As the second hand seller's say that they got gift or it is not used much. And you get it for half the price. So how do trust the seller???
Well Check Flash (ChkFlsh) is a very simple
flash drive testing and maintaining tool. I use this tool to run a burn in read
and write test on the drive. It gives a very detailed information about the Flash drive.
Other than checking for drive errors, it can also determine the read and write
speed. Check Flash is a free and single portable executable file. So you can always carry this single file with you always. It can only test USB
flash drive. I tried to use it on external hard drive and I was unable to select
the external hard drive from the drive list.
