Questions about moving Ubuntu to a new hard drive

[Craig Hagerman]

Hi,

I am running out of space on my computer and thinking of replacing one of
the hard drives with something much bigger. Right now I have an 80 GB ATA
drive, a 250 GB SATA and a 300 GB SATA. Ubuntu root (and everything else
Ubuntu - I don't put /home etc on a different partition) is on the 80 GB
along with a Windows XP partition (half and half). I am thinking about
replacing the 80 GB with a 500 GB drive. What I am wondering is:

(1) what is the best way to move Ubuntu to a new hard drive? Will something
like "cp -pR" work? Or should I do a bit-for-bit copy (with dd?). If I copy
the 80 GB and then replace it with a 500GB ATA I assume that it will have
the same address and I can leave Grub alone. Is this correct? If I instead
put in a new SATA drive, can I just alter the grub boot file and everything
will be OK?

(2) Are there any issues involved with using an SATA drive to boot from. I
seem to remember there were some issues a couple years ago when I first
built this computer... but I can't remember what it was any more? Maybe it
was that windows doesn't (or didn't) like to boot from SATA? If the new root
drive is SATA will I face any difficulties I wouldn't with ATA?

Thanks in advance,

Craig
