Hi guys I am a newbie on iMac .. I have the i3 3.0GHz... my Identifier is 11,2 so its around Mid 2010? What my problem is... my hard drive died on me... or atleast I think it died on me.. Here's the thing.. I left my iMac opened for about 3 days or 2 days straight.. cause I was downloading stuff for work.. and when I sat on it.. I noticed that it froze.. so what I did was to of course restart my iMac... but then it won't boot up.. it suddenly flashed a "stop" image on the gray window.. and then after that a folder with a question mark pops up and started flashing.. I did every tutorial on how to fix this.. but mostly about resetting PRAM or NRAM or something it is called by that.. Anyways.. it didn't worked.. so I tried the disk utility method... so I got my installation disk.. put on the DVDROM.. and waited for it to boot.. for a fresh installation.. but the thing is.. I don't see the partitions.. to where should I put my OS... So I checked again on the disk utility.. and it can't detect the Hard Drive.. I tried several times of restarting.. but still it doesn't show.. the Hard Drive.. I mean literally it doesnt show the HARD DRIVE... cause normally you would see the partitions and the Hard DRive itself... any solution to this?? can I still save my hard drive? My iMac is around 1year and 1 month old.. And as for my Hard Drive solution.. I was thinking to get a new one.. but the thing is.. can I buy any brand?? cause I read somewhere about apple having problems with other brands? But some says it's Okay.. unless its SATA... and how big should I buy?? I mean.. 3.5" or those for the laptops? cause I don't know.. Any help will be appreciated..
