I just installed my new hardrive into my imac and when I turn it on I come to a blank screen that contains a small, blinking folder icon that altenatly show a mac "Finder" icon, and then a question-mark. I opened the computer back up and found everything installed correctly. All the wires were attatched and nothing was missing. I put my old HDD back in and the computer worked fine. The new ram (which was installed along with the new HDD) was recognized and everything was running fine. What do you guys think the problem is. I'm using a 17 inch 1.8 GB G5 iMac ( without iSight camera) and I'm running the latest version of tiger. The new hardrive I installed was a WD Caviar SE16 500 GB SATA Hard Drive. I bought it from NewEgg. Any and all help is appreciated (even tips on returning the drive.) Hopefully I'll have the drive intalled correctly tomorrow. Thanks in advance! Justin
