I just won this hard drive on ebay for £1.70 with the intention of putting it in my amiga once my 2.5" cable arrives.
Its a 2.5" 2.1gb IBM travlestar.

However looking at the pins on it, it seems 4 of the pins (on the left in that pic) are set to the side a little, but when i looked at the picture of a 2.5" hard disk cable there is not gap on the plug it seems.
Have i baught a unusable drive? Just wondering.
