Hello all,

I want to replace my existing 16GB 5200RPM Hard drive for a 160GB 7200 RPM hard drive.

I have taken the casing off my PC and found the hard drive which has an IDE connection.

I feel able to physically take out and replace the hard drive but concerned about getting the PC usable again.
Once the hard drive is replaced, do I just press the start up button and insert my Windows XP home disc and install that?

I am not comfortable with going into BIOS mode or any blue screens, will I need to do that?

Thanks for any information.

You shouldnt need to go into BIOS. If you did, it would just be to change the boot sequence so its not trying to boot from a hard drive that has no operating system on it.

If you cant get it to install on the new hard drive without going to BIOS you can always put the old one back in and boot up fine until you are more comfortable getting the new hd working.

Thanks for the reply.

That is a good point.

So I could take the old hard drive out carefully and store it, install the new hard drive and then try to install my Windows XP cd onto it.
If it works then that's fine and I can then add any software I want to.

Or if I can't get the Windows CD to install I can always get the original hard drive back in until I do some more research.

As long as the PC will work as normal after re-installing the old hard drive I feel comfortable at attempting this so will order one.

Would you please look at the following 3 and tell me which if any should be avoided for any reason?

They are all fine, only major difference besides company is buffer/cache size, and generally a larger cache is better. I would get the WD Caviar if you have no personal preference for Seagate.

BTW, some companies include a disk copy program so that you can transfer all of your data to the new disk. You just need to put both disks in at the same time, then run the program and after that remove the old drive (to save as a backup). You should be up and running on a larger disk.

Thanks for the reply, I will go ahead and order.

I have been doing some reading and think I understand how to jumper the hard disk.

But why is it necesarry to format a new disc drive, I would have thought it would be empty/clean when new? (I understand format to mean wipe clean).

How do I "configure the systems CMOS so it knows that there is a drive?

Most recent machines the BIOS/CMOS settings are set to be automatic, so there is nothing that you need to do. You can set it to ignore a disk, but unless you did that, there is nothing to worry about. If you need to change it, you just go into setup and find the disk settings. The actual process depends on the motherboard firmware.

What is often called "formatting" is actually just creating a filesystem. It is best to recreate the filesystem just so that it is clean as you never know how it was actually created before, even from the manufacturer.
