We have an old 3.x server whose hd is dying (kernel: hda: dma_timer_expiry: dma status == 0x61) and accessing certain files just crashes the system with a reboot.
We have moved as many files to a nfs server as we could so simply.
The system has been heavily modified (all using rpms) from baseline.
What is the most practical method to replace the hard drive?

Install another drive (same size or larger), boot from CD in rescue mode and use the dd utility to copy the old drive image to the new disk (example: dd if=/dev/hda of=/dev/hdb). However, the failing hardware could make this problematic. Then remove the dying disk and install the new disk on the cable where the old disk was so that the new disk is now /dev/hda.
If you are lucky enough to succeed consider mirroring with Linux software RAID or at least make a full backup.

Tried this, I should have been more clear above. When I access certain sectors the machine reboots.
Ideas on how to do the duplication in this scenario?

I don't know if your aware of this but "dd" will mark bad sectors on the drive. Maybe that will help out. I am not sure if it can be done with data on it!!!!!

Just to confirm: you mean the machine reboots even when this disk is not a system disk? Suppose you mount it readonly (maybe it's doing atime updates unsuccessfully?)?
If it's a peculiarity of the controller, you could try putting it in as a data disk in another machine with a different kind of disk controller. You could even put it in a Windows box and use one the various free utilities to look at the Linux filesystem - perhaps that would not exercise whatever issue is causing the reboots.
If you've gotten the vital data off and any customizations out of /etc, the crontabs, etc., then if possible, maybe you could just do an "rpm -q -a" to get the current package list, and then diff that against the list you get on a fresh install to figure out what you need to add.

I am going to put it in a USB enclosure and follow the other advise here so far. 1st try the noerror, etc.. then try the ddrecover

The issues is are there files outside of rpms which are needed but unknown?
The system has evolved from a pre rh7 box (was that ever fun)

Why mount it at all? Booting from CentOS CD in rescue mode gives you the option of not mounting the existing CentOS installation. dd does not need mounted file systems. With the exception of possible IDE conroller issues, booting from CD and not mounting is as good as putting the disk in another machine.

Try using conv=noerror with the dd command.

dd if=/dev/hda conv=sync,noerror Have you used the noerror option? Boot with a live image mount the drive then mount the of=drive to copy the data. Only other option I know of at the moment.

Did you try ddrescue? http://www.gnu.org/software/ddrescue/ddrescue.html
