Re: What type of hard drive goes in a VGC-RB42G.....SATA...
Hi JG78 - If you bought the stock model of your PC it originally came with a SATA 250GB drive. SATA drives have a faster transfer rate so if your PC can handle it ( and it can ) then you definitely want to get a SATA drive. Make sure you back up any info,documents,pictures,etc on cd's or dvd's. Or when you install the new drive you can just make your old drive a secondary drive and transfer the info you need to save before you remove it. Also be sure you have all software and drivers you need before you install the new drive so you won't have the hassle of having to locate them later. If you need to download them you can put them on a cd so they'll be ready to go. If this answered your question PLEASE rate this as fixed. If you need more help or assistance with this just add a comment and I'll be glad to give you a hand. Thanks.

How to connect your hard drive to your motherboard
The first thing you have to figure out is what type of hard drive you have, a PATA or a SATA drive.
PATA = Parallel ATA
This type of drive uses the older IDE connections. Most of your current motherboards still have aleast one IDE connection to support the ROM drives on the market that have not moved over to SATA connections but you can still connect a hard drive to this connection if needed. The thing to keep in mind is that you can only connect 2 IDE devices to one IDE connection on the motherboard.
Here is an example of an IDE cable. If you can see there are tabs on the cable to make sure you line up the pins properly.
SATA = Serial Advanced Technology Attachment
This type is now the standard that most hard drives are. Also note that alot of your ROM drives are switching over to this format as well.
Here is an example of a SATA cable.
In regards to power connectors If you are using a PATA drive then you will use the Molex power connector. Note some of the early SATA drives use this power connector as well.
For the SATA drives you would use the SATA power connector. Note if your power supply does not have this connection you can get an adapter that goes from a Molex connection to the SATA connector.
Next you will need to find the connectors for the hard drive on your motherboard. Below if pictures of the 2 connection types.
It depends upon where the hard disk is to be installed, ie. in a desktop computer, in a laptop or in an USB hard drive case.
A 3 1/2 inch hard drives can be a IDE/PATA or a SATA type. Older computers use IDE/PATA hard drives and the maximum size you can install in a desktop depends upon the computer's BIOS. SATA hard drives are generally used in later model computers and the size of the hard drive is not limited by the BIOS.
A 2 1/2 inch hard drives are used in laptops and are available in IDE/PATA and SATA types. The size and limitations of IDE/PATA hard drives also apply to laptops. The same applies to SATA hard drives. The choice and size of hard drive depends upon your requirements and how much you want pay. Don't forget to check BIOS for the maximum IDE/PATA hard drive size you can install in your computer.
Sony has yet to support Windows 7 on the VAIO VGC-RB42G. I would strongly suggest not to try to install W7 on that machine. Sony is a _very_ proprietary equipment. There is a very good chance that you won't be able to obtain the neccessary drivers nor W7 having the correct drivers available. Generic drivers don't usually work on Sony equipment and vice versa. If you are determined to try it, it would be best to contact Sony first: http://esupport.sony.com/US/perl/select-system.pl?DIRECTOR=CONTACT
The next step, especially for a Sony is to visit the website and check for software upgrades and possible BIOS upgrades that are needed _before_ installing W7. In your case I would contact them directly.
Be sure to back up all your data. Copy it to CD's, DVD's, an external hard drive, or a flash drive, or another internal hard drive.
Go to this site and buy a sata hard drive and with the drive will be a disc that will allow you to copy everything to new drive you will have to slave the new drive before you copy but it will have instructions http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2795126&CatId=139
You can try to check if there is a partition on your hard drive where you can restore the original default software installed in the computer. And if your computer doesn't have that partition you can contact Sony and request for a copy of the recovery disc. If you have registered that computer the first time that you got it, you can request it and just pay the cost of shipping.
