Hi
 This can vary, from not working at all to the occational
bad read or bad write of a sector. Some times it shows
up as a data dependent problem. The disk formats fine
but can't write all 1's or all 0's.
 In both of my cases, it would occationally damaged data
on a write that would show up as a non-recoverable CRC error.
 Although it is recommended that the termination be on the
last drive on the cable. I've never found it an issue
when the two end drives cable connectors are only 2 to 3 inches
apart. I have been known to put the termination, where ever
it is handy, while trouble shooting( such as swapping drive ).
 I also alway tape the terminator to the drive that I remove
it from. I don't know if I or someone in the future will need
that terminator. If it is right there, I know it is the right
one.
