Transferring HDD data

Hi all! This is my first post on Tom's hardware, so I'm really sorry if this thread is already somewhere else on the site, but I couldn't seem to find one. Anyway, here goes. I currently have two hard drives, a 160GB IDE drive, and a 250GB SATA drive. Under my computer, they appear as Local Disk C (50GB) Local Disk D (110GB) and Local Disk E (250GB). I am running out of room, so I would really like to get a new hard drive, preferably something along the lines of a single 1TB SATAII drive. My question is, is it possible for me to take all the data from my two original drives and transfer it to a brand new single drive? Would my computer still load with all files and folders in the same places? If someone could explain the process, or what would happen, I'd be really grateful. Thanks guys!

Thanks. So would this be a relatively simple procedure? And would it be safe to do it on my own just using this software, or are there quite a lot of risks in doing this? Would all of my documents, saved games, drivers etc all be recognised in the same places they were before? Cheers.

Get the Western Digital 1TB Black.

WD has a diagnostics disc image and one for installing hard drives which includes cloning.

0) Create the WD Setup CD (or floppy?)
1) shut down PC
2) remove the non Windows drive
3) add the new 1TB drive
4) run the Setup disc and CLONE (partition your 1TB to two partitions. One for Windows and one for the rest)
5) Copy the D content to what will be your future D drive
6) shut down
7) remove the old Windows drive
8) Boot up and make sure everythings okay
9) Shut down and add the other drive, then copy the data
10) I'd keep a second drive just for creating backup images (i.e. Acronis True Image) and backing up critical information. In other words, plan for the case that your 1TB drive failed. It's reliable but plan anyway.
