A hard drive can be any size you like provided it's the same type of drive as the one that's stopped working. Your hard drive is very likely to be a S-ATA (Serial ATA
) drive but could be a SCS (Serial Attached SCSI
). If it's only 1 year old, it's very unlikely to be anything else. Take out the failed hard drive as carefully as possible and make a note of what the attachment to the computer looks like (draw a diagram or take a photo if possible). Show that to a PC techie and they'll be able to tell you which one you'll need (there are several different connectors for both types so I'm not 100% sure if the Wikipedia pages alone will help).
Once you know whether it's a S-ATA or SCS, any hard drive big enough to take your data will do. It just so happens that the larger the drive, the better value it is (unless of course you buy one so big you'll not fill it at any point in the next decade - and if your data needs are modest, 1 TB might be too big).
I'm not sure how recovery disks from providers other than the one you got the original from would work. If Ibuypower's write-up indicates it will work with your particular computer, then that should work on any hard drive. It just needs the same stuff plugged in to your computer as it had when it arrived and you don't strike me as the sort of person who plays Frankenstein with your machine*.
If the recovery disk turns out not
to be compatible with your computer, it'll be because it's missing some drivers (assuming the disk you're looking at includes the correct operating system, which I'm assuming you've already checked). These are invariably things that can be fixed provided you can get hold of an internet connection (either because the modem driver happens to be correct for your computer or because you can borrow a friend's). If the recovery disk misses a driver, you can stick the make and model into a search engine, find out what the bit it's missing a driver for is called, stick that
into a search engine and download the driver that should then appear.
In other words, possible incompatibility with your machine is not a reason to avoid getting a recovery disk, unless you come across a disk that definitely is compatible.
Re-downloading F1 2010 likely depends on where you downloaded it from. I suggest you go to the site you got it from after you've re-installed and check its policy. If it's clear, follow whatever procedure is recommended. If it's not, ask someone in Customer Support, and be prepared to escalate the matter if they respond with something that doesn't answer the question.
* - If I'm wrong, you'll probably have the driver disks for the upgraded lying around somewhere anyway - simply install them after the recovery disk has done its work.
