About two years ago I created HP Recovery Discs (3 of them). Now my hard drive has crashed and new one is still a week from delivery. I was reading up on how to reinstall the genuine OS using the Recovery Discs as i was not given any Windows 7 installation discs.

I did my bit of research after getting answers from the community on what these discs do and found out on other sites that people experience issues when recovering their OS from the disc. Especially when they change the make or capacity of the harddrive.

Unfortunately I had to change the make as the hard drive that came built in has gone out of production.

This question is just a part of my checklist to avoid problems when recovering the OS.
I have:

• HP DV4-2126TX (available only in India I guess)
• I had: Seagate Momentus 320 GB
• I ordered: Western Digital Scorpio Black 500 GB
• Windows 7 Home Premium 32-bit

Is there a possibility to encounter any problems due to the changed capacity and make? I only want my genuine OS and drivers – not my data.

I was told that Disc 1 contained the OS and drivers, and the rest of the discs contained data. I couldn't verify that.
