Kernel panic!

This morning, disaster struck. I woke up late-ish, made breakfast, then settled down in my recliner and turned on my computer. It just blinked a question mark at me. So I found the OS discs and tried to do a repair of the hard drive, and the disc repair utility couldn't even *find* the hard drive. I was worried it was hosed.

I made an appointment at the Genius Bar at the Apple Store, but couldn't get in until 11:30 am. Weird to feel cut off from everything like that. Luckily, I had my old Mac, which works fine except that the LCD screen is cracked and you can't see about a third of the display. That at least allowed me to get online for a while.

Then I headed off for my appointment. Of course, when the Genius guy hooked my computer up to his network, it found the hard drive immediately, and a quick diagnostic scan of the drive indicated no problems.

So all seemed well, and I shut it down, then started it back up while the guy helped another customer. I thought I'd get into my email and upload the chapters of my old story I'd worked on yesterday as a quick back-up of that work. The computer started up for me as well, so I proceeded to open a web browser and I got this message on the screen, which also froze up. The Genius guy looked at it and said "Oh, that's kernel panic."

"Kernel panic" is basically the fancy term for Blue Screen of Death. Which is not the end of the world, but it concerned the Genius guy and he recommended I leave my computer there for the day so they could run a full diagnostic on it. I went to work after that and grabbed my work computer and that's what I'm on now.

Hope everyone's day is going better than mine!

ETA: I did back up yesterday's work after all. I iz so smart!!

That is such a horrible feeling--no matter how careful I am with backups, a non-responding computer gives me kernel panic! I hope they can resolve it soon.

Me, too. The only kernel panic I want is when the popcorn doesn't pop enough.

I have had very good experiences at the Genius Bar (so far). They know a heck of a lot more than me about this stuff, and always seem prepared with ideas for tackling my issues.

I wish they'd call me back and let me know how my comp is doing!

On PCs, you can have a setup known as a RAID Array* installed. There are two hard drives, and the system firmware copies exactly ("mirrors") what is on the one drive to another, everytime anything is written to the drive. If the one drive fails, you can plug in a new drive and the system writes everything back from the mirror to the new drive automatically. This was costly to do many years ago but now drives are pretty cheap.

Does the Mac world have this feature available also? Just curious.

The Mac has a Time Machine external backup that works with the wireless to backup the entire disk on whatever schedule you want. I've just never set it up.

But does that backup only data files, or back up the entire OS? In other words, if your main drive crashes, can you run the entire system from the backup as if nothing had happened? The RAID array allows you to do that (or so I understand.)

So far I've never had my main drive fail so that I could test the thing. My understanding is that you get an on-screen message that the main drive has given up the ghost, and that the system is now running on the mirror drive. You then get a tech (or do it yourself, if you're handy) to install a new main drive, and the mirror drive then rewrites automatically to that one to restore the original RAID function.

If true, it's pretty slick. There is no "backup schedule" and you don't have to remember to backup anything, although I do copy any critical data files to CDs or DVDs in case of fire or lightning strike or something that could manage to kill the entire computer at one shot, since the RAID can't help with that.

I'm sure there's a way to do it, I've just never been geeky enough to pursue it.

Ooh, scary! Hope they can fix it quickly and make sure your laptop stays healthy from now on!

And now I feel the sudden urge to back up all my writing, but really, I just did that last week and it's not like my stuff isn't all online anyway ;)

The only stuff I really "lost" was some stuff I updated yesterday that I didn't back up before heading off to my evening plans. One of those files really miffed me because it was line editing I could never duplicate, but I did back that one up, fortunately. The rest...less of a big deal, but busy work recreating them.

Glad to hear you didn't lose everything! Hope its fixed soon!
