HD SCSI cables

[Prmetime]

Hello,
   I have an A3000 that will not do anything with the HD installed.  I recently had it apart to put a new battery in it and I'm wondering if I installed the HD SCSI cable the wrong way(put it in upside down so the red side is on the wrong side). The HD works fine in a different machine. If I reverse the cable will that damage anything if it is the wrong way? I'm hoping for something simple so I don't have to start swapping  chips.  Any suggestions are appreciated.

I have changed the batteries on both of my A3000s and I didn't have to do anything differently on the other mahcine.  It boots up fine with either Hard Drive.  While I suppose I can look for the setbatt utility (is aminet still down?), I don't know why one A3000 would boot fine and the other will not (at least not due to the battery anyway). However any help is appreciated.

Thanks everybody.  I will try to figure out what is going on here based on your input.  I'll let you know if I find anything.

Out of curiosity, where would I get a new scsi cable if I needed one?
