is your hardrive suspended? It kinda looks like it just floating there. You can just barely makeout what looks like a rubberband. If it is a rubberband you should be careful because they become brittle and break especially when they are dryed out by heat.
Yup - suspended by rubber bands (secured to the top edge of the drive with 1 of those brackets to convert a 3.5" device to a 5.25" bay). And yeah I know they break and I really should raise the quality, but I have my cases open every few days because I enjoy playing (anyway), and my kids bought me a bag of bands for my birthday
(Naturally I blame the camera for the picture quality - actually was trying out my new mobile phone with built in camera.)
