I am shopping for a new HD for my G4. Can any tech experts confirm if the following HD will be compatible or will work in my 2001, Power Mac G4 (Quicksilver), 733 Mhz. The HD I am interested in is the following: Western Digital Caviar Blue WD2500AAJB 250GB 7200 RPM 8MB Cache IDE Ultra ATA100 3.5" Internal Hard Drive - OEM Can anyone also explain what the difference is between the "Interface" types, IDE, SE and SATA? and if this relates to the compatibility with older Macs (G4's)? http://www.newegg.com/Product/Product.aspx?Item=N82E16822136199 I would like to purchase this HD but want to be sure it will work in my G4. Any insight or knowledge in greatly appreciated. Thanks so much!
