The joys of corruption
Discussion
Sadly i've not received a cheque for my part in the zimbabe vote rigging.
What i have received though is a simultaneous collapse of 1TB of drives in the most fantastic self-corrupting fashion.
The next trick is going to be using VMWare to boot it off another drive and see what i can recover.
Just what i wanted on my last day before work

Use Raid
I find that chanting random phrases from Aleister Crowley's 'The Book Of Lies' whilst pogo-ing around naked covered in blue paint and gritting sticks of RAM between my teeth wards off the evil spirits of hard drive failure.Use Raid
That, and keeping them cool.
Never trusted Crowley enough to go without a backup though, dodgy geezer he was, yes sirrreeee.
(I don't normally correct Jamie B because he knows more than me about hardware but if you're going to use Raid, make sure it's not the ant killing stuff first, and then make sure it's not Cyberface and LukeBird style 'suicide' RAID-0. But Silent1 old bean you knew all this anyway, except perhaps the bit about the hard drive black magic. Hmmmm.)

Which is fine until the controller dies and wrecks both disks.Use Raid
Obviosuly RAID should be your first, not last line of defence anyway.. but what would you advocate over RAID?

I've seen it happen twice. Faulty RAID card happily hoses both (or all) disks on it.Obviosuly RAID should be your first, not last line of defence anyway.. but what would you advocate over RAID?
I'm not advocating anything over raid, just agreeing with your first line of defence theory.

the perfect defence mechanism is RAID on the server and then one of the new CDP (continuous) data protection engines that effectively journal all writes made by a server and allow you to recover to any point in time... Legato replistor is one we've played with in the labs actually transparently sniffing writes off the SAN, but it has a host based splitter as well..
You replicate to a remote location - and this then becomes your backup (so raid protect it) ...

Aaah can't beat suicide RAID Ash 996 GT2 said:
RAID 0 acheives nothing apart from performance!
Indeed, but if performance is what you want (need 
) then it's great 
I should add that's on my personal machine and the work machines I have control over (as in, not part of our work network) are RAID 1, which just isn't as 'nice'!

Also, I've seen two hardware Raid controllers die in quick sucession - thus taking out my Unix box with Raid 10
Bah.
p.s. the special Harddrive dance works.

Ditto to both points - I've just suffered the perils of suicide Raid at home, and thus realised there was absolutely no point at all in doing it (apart from wasting hours).

I can only speak from experience here.Also, I've seen two hardware Raid controllers die in quick sucession - thus taking out my Unix box with Raid 10

Software raid is worth exactly as much as you've paid for it.
Hardware raid on a cheap / integrated low end mobo again as such.
Pay for a decent card, and you're as safe as houses (as part of a calorie controlled diet!)
RAID Card failure is certainly something I'd stick in the <1% chance of happening on decent kit.. but as always, your stats are only as good as the quality of your kit.

Sorry, forgot to mention that the two failures I've had were both on high end Compaq kit (back in the days when they were good Compaq, not HP).You don't seem to realise that I'm agreeing with you, although I'm happy to have an argument about it (whetever it is) if that's what you're after.
