If it's any comfort, my PC died last week. Again.
Just after New Year we had a cold front come through with a lot of thunderstorms, which in Houston usually means huge power surges as the mains cables are mostly still on poles down the side of the roads with "pot" transformers (up the poles) stepping down the voltage to distribute to houses. FWIW I live about a mile from the old, pre-merger with HP, Compaq HQ, and NASA is about 40 miles away. And they can't get the electricity to work properly. Go figure.
Anyway, that fried one hard disk in a 4-disc RAID1 array. [Insert one rude word]
No problem, the RAID array did what it was supposed to and a simple 85-Dollar hard disk replacement had me back up and running.
Then, last week, another hard disk in the array went belly up. [two rude words]
The PC wouldn't boot at all ("checksum error") [three rude words]
So off it went to the local PC repair guy who changed the CMOS battery (a good tip for anyone with an older PC - change it every 2 years come what may), a Windows reinstall and it was up and running.
Trouble is this time the RAID array didn't do what it was supposed to - I think two disks are "donald ducked", the original and the mirrored copy backup - and I lost about 3 days worth of CAD stuff I had done for the wife. [approaching Roy Chubby Brown level of expletives now]
As I type, the second replacement hard disk is integrating itself into the RAID array and the last duff disk is being scanned to see if I can recover the data from it.
If not, three to four days of re-creating the drawings from scratch again. [Roy Chubby Brown and Bernard Manning combined levels of profanities now]
The PC now has a UPS as well as a surge protector, two brand new hard disks, a third on order, a fourth and fifth (one for the RAID array, the other to RAID the boot disk) to be ordered next week, and a gizmo where I can plug in a full size SATA hard disk, without taking the case off, for yet another layer of backup. Short of renting Cloud space at some humungous cost, I should be bulletproof now. However, there isn't a machine built that yours truley can b*gger up....
