I have a Sony Vaio PCG-FX170, I have been getting the error "SMART failure predicted on Hard Disk 0" I know that this means my hard drive is going to die soon. What I want to know is what kind of Hard Drive could i get for the computer, as I have read the ones exactly like the one i have in the machine have been know to have some problems. on the "SMART failure predicted on Hard Disk 0" screen it tells me the name of the hard drive. its a Hitachi_DK23BA-20, other wise known as a 20 gig one. I found this description of it on the hitachi website and it says the interface is ATA-5 (Enhanced IDE) is there any other hard drive i could use with this laptop as opposed to the model it came with? If so, could you please explain in detail what i need to look for, and if you know of any deals please share them. Your replies are appreciated.
