Emergency back-up underway

One of the three parallel IDE drives remaining in my computer is dying.  I’m not sure which at the moment, since they’re all in a span array and I’m more concerned with getting all of my precious music and videos off of them.  I’d been meaning to do it for some time, knowing that at least one of those drives had been acting funny and that the disk span was, well, fault intolerant.  But I just kept putting it off.  Well, today, after a spree of delayed-write failed messages, the urgency of this matter became clear. 

I’m tempted to just do away with these Parallel ATA drive altogether.  I’m certain the newest of the three is fine, so I’ll definitely find it a new home if it leaves my computer.  The other two I don’t trust quite so much (they’re the same model of Western Digital Special Edition drives). 

My primary system disk is actually two WD Raptors in RAID 0 that have been fantastic.  My main storage disks are two Maxtor 16MB cache 300GB SATA drives in RAID 0.  None of these disks has had any problems (knock on wood).

Maybe it’s time for one of those new-fangled networkable hard drive dealies.

 

Followup:  The disk isn't actually losing any data.  Scandisk finds nothing wrong with it.  It simply has a habit of “falling asleep“ and not waking up again properly.  I can reactivate it in Disk Manager after it does this and it works fine (for a while).  I'm still planning to remove it from my system... but at least no data was corrupted.

I can't stand raid 0, why not use raid 1 or raid 5? you get true fault tolerance, raid 1 gives you 2x read speed, or raid5 utilizes all the drives the best...

Honestly I'd never trust a raid 0 array, except on a game machine or something else that I didn't truly "care" that the stripe failed... 5/2/2005 1:33 PM | Eric Newton

I'm sure if someday I encounter a failed stripe, I'll learn that lesson ;)

But I do backup vital information often. My main RAID 0 array contains none of my actual data. I consider it expendable, as it's just a custom Windows XP DVD away at anytime.

As for the other options, RAID 1 is just not worth the cost in disk space on my home machine. And RAID 5 isn't an option since I don't have three disks to do it with :)

The drive that is failing slowly is on an NTFS disk span (I use Dynamic Volumes). It was basically my attempt to use some "leftover" drives for additional non-vital storage. 5/2/2005 1:50 PM | Brandon Paddock
