One of my computers(XP SP3) has a failing boot drive (I think).

Symptoms are:
Want's to do a scandisk at every reboot.

Had a couple of BSODS, Microsoft problem reporting says(amongst other things!), try removing any new hardware(I just changed the motherboard and CPU!), that ain't happenin'. The scandisk thing has been going on for a while. Or try checking your harddrive for errors.

So I've already replaced the boot drive once before using Western Digital Data Lifeguard Tools(a while ago).

Now I'm doing it again, same tool.

Background Info

I have 3 Domain Controller/File Server/Web Server computers with Raid 5 Arrays. I upgrade these arrays when I can afford it. I tend to use the "OLD" raid drives as replacements for failing boot disks. Currently I've got a bunch of 160gb disks(the arrays are using 320s).

I'm not that worried about using "OLD" disks because it seems to me that HDD longevity is pretty random(1 of the servers has an old 20gb boot disk in it).

Here's what I'm thinking about doing:

Replace all boot drives with Solid State Devices as soon as they get cheap/fast/large enough.

Install all programs to to an additional mechanical drive.

Questions:

Does anyone know of a better(free) utility for replacing a boot drive?
Any other thoughts?
