I called Dell to get a HD replacement and was told a 310 gig would work in 4600 model. I installed the drive, went into setup and switched bootup to cdrom and it would not boot up. Called Dell tech and was told it would not support that size drive. Not sure what to believe at this point. Anyone else had this problem with Dell's tech support and sales departments. This is my last Dell to be sure.
1. There cannot be a hard drive size limit for a computer. It depends on OS.
2. Neither there cannot be a 'support' decision made be its hard drive size.
Above are nonsense responses and I think the ones you talked to are simply hired people who don't have knowledge on computers. You should continuously ask for a tech guy (who really knows stuffs) don't even waste time on simple representatives who responds with ignorance.
