Mac won't recognize hard drive


Ok so I have a mac pro and when I first started using my hard drive it was working fine but then I was cleaning out my computer one day and I think I accidentally deleted the program that recognizes the drive and now it won’t show up. Iive tried downloading the software and firmware off the web site but it didn’t do anything I need help… What do I do???


I have exactly the same problem. I did load Snow Leopard during the week and wonder if that is the source of my issue. So lets hope somebody out there can help…soon!!
