Thanks for the answer
- I'm almost 100% sure the hardrive is OK.
I have connected to to my desktop through a usb caddy and everything loads fine - I can see all the files and copy files that are not encrypted. The encrypted ones are in my "documents" folder. The filenames are green so this matches the description of XP encryption.
I have tried another drive in the broken laptop and it still doesnt boot up. The power comes on but no life from the screen or the fan inside.
