Replaced hard drive, but it isn't recognised

I've replaced the original hard drive with a Seagate - Momentus 7200.4 ST9320423AS - Hard drive - 320 GB - internal - 2.5'' - SATA-300 - 7200 rpm

- but no hard drive is showing on the screen when I try to install Snow Leopard.

Have I made a dreadful mistake and bought an incompatible hard drive? Or am I doing something wrong re. formatting the new hard drive? I've put the original HD back in again to check that the laptop is not irretrievably broken, and that still works OK.

Start up from your system installation disk by inserting the disk and holding down the "C" key on start up. Go to the second screen pull down menu to Utilities > Disk Utility. Select the drive on the left and format it Mac OS Extended. Quit Disk Utilities and continue with the system installation.

Thanks so much.

However, I now have a different problem. When the new hard drive didn't work, and I replaced it with the old one to check, I did this without putting any of the screws back in (don't know if this has any relevance) as I wanted to switch between hard drives quickly. It all worked fine - and then suddenly crashed and has not worked since. I press the start button, and absolutely nothing happens. Another confession. I lost a Philips screw, one of the ones in the very first step. Looked everywhere for it. I can't see it in the laptop, but I'm wondering if that's in there somewhere and has short circuited the system - or could there be a fuse blown somewhere? The internal workings don't look any different, nothing looks brown or blown up. Thanks for your help and advice.

Search around the magnets. Turn it upside down and shake and listen.

@mayer: your answer is very good but instead of formating the HD Mari should partition the new disk (one or more partitions) and make sure to select the GUID partition that is needed to install a bootable OSX on a Intel Mac.

Hello there, there is nothing wrong with partitions if you will be running another operating system along side what have. Otherwise another partition would really not be necessary unless you just feel better by simply just having one, it's the same hard drive regardless.

One partition is the whole drive and by giving it one, it sets up a GUID partition scheme and makes the drive usable on an Intel processor machine. Else wise it may set up as an Apple partition scheme which is used by the PowerPC processors.

As this is an internal drive in an Intel based system stick with a GUID partition.

Here you could go either way, with smaller HD's it doesn't make sense creating multiple partitions. But, with larger drives it can be very useful!

First, HD maintenance (defrag & repair) is easier and less time when you have multiple partitions (2). In this setup the first partition has your OS & Apps, the second has your data files (docs, music, pics, vids, etc.) as these files are always being added to or changing this 2nd partition get defraged and needs file repair the most so it will need more maintenance unlike your first partition as it won't get much change so it doesn't need the same level of TLC to get the best performance or system reliability.

Lastly, backing up takes less time and space as you only need to back up the first partition if you add or upgrade your OS or Apps. Unlike your second partition which needs much more effort to keep it backed up.
