weird laptop issue

[nandac]

i had an old ibm t42 thinkpad, which simply didn't boot. it originally had windows xp on it.

i found a disk with windows vista and so i booted the machine with this disc and so got it up and running.

i don't remember the configuration as it was originally.

then today i checked hard disk space and found that it had like 70 odd gb on it. then i rebooted the machine and now it is showing C:\ as 30 gb!

not sure whats happening. appreciate any insights.

I think your old xp OS is still residing in the laptop and the new vista would have been loaded as a dual OS. Try to check this.

Thanks

You can try booting with a Linux Live CD.
That way you can see all folders and their size with GUI view.
