Jeff,

Thanks for the info I will print it up and bring it to school Monday to complete the transfer.

Actually, the only partition that's going bad is /. There are separate partitions for /boot, /usr, /usr/local, /opt, and /home so I don't need to worry about them. I had no trouble making a swap partition and new file system on the replacement drive. The main thing was that when trying to figure how to copy / without copying them, I didn't think of just unmounting their partitions. The simplest ideas are usually the best.

Something I'm trying to understand: yesterday whern experimenting with this I made the new /dev/sdd2 partition mount as /newroot, then made a /newroot/etc and tried to copy everything from the old /etc by using the command

cp -f -R /etc/* /newroot/etc.

Everything copied, but very inefficiently. When I did a du on the old /etc it was about 2700k, but a du on the /newroot/etc showed about 6100k. Do you know why the copies took up so much more space? It would make sense under DOS with its inefficiencies, but Linux???

Thanks again,

Greetings!

This happened to my IDE drive a couple of months ago at the University, and I recently replaced the 10 gig with a 20 gig on my system at home.
Do all of this in single user mode to keep things easy...
Ok, you've made your partitions and done the mke2fs on them from what I understand. (If not, after you partition, you need to "make" the file system mke2fs /dev/sdd1
for each partition of Linux you are going to transfer. The rest is easy.
Mount each partition in turn on a temporary mount point (I call mine /transfer).
mount -t ext2 /dev/sdd1 /transfer
Then for every partition EXCEPT FOR / you can issue
cp -Rp /usr/* /transfer
This copies all of the files and directories from /usr to /transfer preserving
the structure and dates, etc.
