Question

How to use a healthy RAID 1 mirror drive when 1 gets corrupt

Jan 27, 2012 6:36AM PST

Dell told me, when buying my Alienware M17x, that Raid 1 allows one drive to survive a crash. What are the steps to use the HDD that is still healthy? My computer includes a Raid 1setup and I've had multiple blue screens of death. What are the steps necessary to now use only the healthy mirror drive, without using the corrupt drive--which was my main reason for having set up the RAID 1 drive in the first place. At set up, I first created the RAID 1 and then installed Windows 7. Does anyone know how I can take advantage of having access to a healthy drive and how to determine which drive is the healthy one.

Good question. You may not like the answer.

The answer changes with each RAID CONTROLLER. And gets worse if there is any SOFTWARE RAID system.

But in theory on the old standard RAID controllers of old, you did nothing but remove the failed drive.

Hey Bob,
Thanks for your insight. Based on the old standard, how would you select which one of the two drives failed? Is there a process used to determine which one to remove or is it just the old trial and error? Thanks, Trusthim12

I select the failed drive by testing.

I pull one, test and if not, put that back in and pull the next.

A "proper" RAID 1 will function fine.

even with one drive missing, the machine should boot and behave normally. You should have got a warning when you booted the machine saying that either drive 0 or drive 1 was corrupt/non-bootable/missing and then be given a choice to boot from the second drive.
