So ... how come no one told me I had to "boot from CD" during boot up process to format and install windows? (I forgot that process ... and I didn't need a password either!)
At any rate, I just did that, hoping I selected the correct things for input (partition yada yada, not a clue but I just selected things hoping for the best, including "format" first) I must have done it right because it installed windows xp fresh from a disk, but same problem as before. Its NOT a valid/genuine windows says MS
I guess the one that came installed on my small old drive is the one I have to use since I have no disks. Oh well. Such is life eh?
I'm currently in here on my new HD with the un-genuine windoze, unsafe surfing
I can answer so of your questions now, I was on my iPod Touch all weekend.
1) Yes you need the Microsoft Genuine Validation password to properly install windows.
2) There is software to clone your old HD onto your larger newer HD. If you know the manufacturer of the second HD you can usually download the software for free from the maker. There is no guarantee the maker has this software available for download but it is usually included with brand new HDs.
3) If your machine is a few years old as I presume it is, most motherboards have two IDE cable connectors. Each IDE cable can usually control two devices (HD, DVD-RW...etc). One end of the cable will be attached to the motherboard and one end will be attached to the HD. It might also be connected to the DVD/CD-ROM drive. You will probably need to change the jumper setting on the second larger HD to slave then you can plug the cable into it.
Wiki has images of the cables:
4) After you have both drives up and running (you can see both drives in Windows Explorer) you can format the second drive to hold data:
START>Setting>Control Panel>Administrative Tools>Computer Management>Storage>Disk Management>Right click the HD you want to format>Click Format
START>Programs>Accessories>Windows Explorer>Click My Computer>Right click the HD you want to format>Click Format
5) If your computer is working fine and your only problem is lack of space it probably would be better just to add the second HD and move all you saved files (JPG, PDF, DOC ,AVI, MP3, TXT...etc.) to the new HD. Also when you do downloads you can save them to the second larger drive and not have to worry about taking up valuable space. The other advantage is if you PC crashes you are less likely to lose your valuable data because it's not on the main HD. If worse comes to worse you can remove it and install it in another computer or put it in an external case and access all the data with another PC.
Hope this helps
