Dual drives (Mirror Image)

I would like to know how I can run a second drive on my system that will be a
duplicate of my C drive. Every time something changes on my C drive its
immediately updates the second drive.

So, if my C drive fails, I will be able to boot from the second drive. The
second drive will be a mirror image of C.

Thanks.

Thats called a RAID set,but one needs a RAID controller,MB,& the correct
hds for it to work,or buy a RAID controller add in card (pci) + the hds.Or
if you
run IDE hds,set the 2nd hd as slave to C: on same IDE cable,format the new
hd,once thru,go to run,type:XCOPY C:\*.* D:\ /c/h/e/k/r Agree to all in the
DOS window.Once its thru,C: is now on new hd & bootable,also D: being the
new hd,but if given diffrent letter,then use that letter.Changes made
currently
if left as is,wont change D: as C: runs,but you'll have a back-up 2nd hd....

Andrew, XCOPY will not work properly for this purpose. Please make
sure that your advice is valid and correct before posting it.

If your motherboard has RAID capabilities then you can just connect up
the second hard drive and activate the RAID. Disk mirroring is also
called RAID 1 or RAID level 1 and that is what you want.

If your motherboard does not support RAID then you could purchase a
RAID disk controller (Promise is one manufacturer) and connect your
drives to this.

Another option would be just to install the second hard drive and use
disk mirroring software to create a software RAID. See

Good luck
