Thank you i have got the files i needed now. Is there a chance you could tell me how i can get both partitions merged together, so i can use it as an external drive for back-ups. as this is alot better to use for traveling unlike my other external hard drive.
Thanks again for your help.
If you don't need any of the files anymore on the old laptop hard drive and want to start clean, you can just delete all the existing partitions on the laptop drive and make a new single partition using all the space on the drive. Just go into Disk Management as described here. Make sure you are deleting partitions from the correct disk! (the laptop drive, NOT the one in the computer currently booted up!). You can do all of this in Disk Management.
Of course, this assumes you are completely done with everything on that laptop drive and will never need to boot it again! It will erase the operating system and everything else on that laptop drive, so you need to be sure!
If you want to keep some of the old files on your laptop drive - maybe the operating system so you could, if need be, boot that laptop drive again - you could delete just one of the partitions - I assume the one that had your data on it - and then grow the other partition to use all of that new free space on the drive. You can again do this in Disk Management in Vista or Windows 7 (not XP though).
One caution about using an old laptop drive for backup: you need to make sure the old drive is in fact good! You didn't say what happened to your old laptop(?) but if by chance the disk started to fail (but was still readable to get files off) you wouldn't want to use it for backup! I use a free tool called Crystal Disk Info (google for it) to check the S.M.A.R.T. status of my hard drives. If you check the status of your laptop drive with this tool and it says "Good" status, then you are pretty safe in using that laptop drive for backup.
