OK, So is this what you want me to do??
1) Buy a pendrive.
2) Perform the tests you have mentioned in the post.
3) Find out that the drive has no writing on the head, the slider color is blur and sliding out is not smooth, plastic is lighter and there is no thin plastic blister, the disk tilts downwards when plugged in, the drive is named as 'Removable Drive' and the transfer rate is slow at the beginning and then suddenly rises.
4) Realize that I have a fake pendrive.
5) Cry over my 'bad luck' and start over from
Step 1 till I finally find a Genuine Kingston pendrive!!
Really?? Is that what you expect us to do?? :S
