SATA drive connection

I know its a silly question but the nearest computer store is 2 hours away.
could/would someone kindly look at the SATA pins where the SATA connector goes
and tell me if the pins are all the same lenght or are some shorter than
others??
I was working on cleaning up the wire mess inside when I accidentally knocked of
the SATA connector from the drive.When I attempted to reconnect I noticed it was
harder than before and upon inspection saw some pins were shorter than
others....so did I damage the connection??
The connection seems really touchy from that point on.To be on the safe side I
ordered another SATA drive with a more secure connection..should be here next
week.
thanks in advance
