Hello, I want to upgrade my thinkpad T23 15GB HD to an 80GB one. - Can I use an external 40GB USB HDD to clone the image of the old drive to it, and from there to the new hard drive using PowerQuest Drive Image? I was planning to do it like adviced in http://www.mikeshardware.com/howtos/laptop_hd_upgrade/, but now I think it would be great if I could use the external HDD I borrowed actually for backing up data only, instead of going via a desktop PC. Also the link I mention is not very new, there might be better ways? I guess one question is if my thinkpad's BIOS (date 5/29/2003) can boot from the USB drive? Or, can I boot from a boot disk, formate the pristine HD that is then in the laptop and get the old HD image from the external HDD to it? I don't get any support from IBM because out of warranty. I would like to clone the old hard drive to the new one because I bought the laptop used with everything installed so I don't have any installation CDs for operating system etc. If I would not need to transfer the programs from my old hard drive, but could install everything from scratch, I guess this would be much easier. Right? I am sorry if I am asking something already discussed but I could not find a helpful thread for this. I'd appreciate any help.
