Hard Drive issues

Hi everyone,

I've been having hard drive problems with my iMag G5, bought last summer. Basically what happens, is over a couple of weeks, the computer starts to simply "freeze up" occasionally while you are using the computer. Then, what happened this morning, it won't turn on at all. Trying to boot into single user mode sort of works, I get to a command prompt, but when trying to boot the system, I get "disk0s3 I/O" errors.

The "fix" I have at the moment is to reinstall OS X. I've done that twice now.

Running Disk Utility's repair disk feature was failing this morning, it wouldn't complete. Last week, it rand without issue, reporting a clean bill of health. Using the Apple Hardware Test, I could find no errors.

Is this likley to be a software issue, or, as I suspect, a slowly dying harddrive?

If so, what is the best way to get it fixed? I live in the Netherlands, and the closest "Apple Authorized Service Provider" to me wants to charge me for a "Service Agreement" - which would clearly be a charge for warranty service under an existing warranty.

Any help would be great,
Douglas

iMac G5 (no iSight), Mac OS X (10.4.3), System freezes, no booting, and disk I/O errors.

Hi Douglas,
Welcome to Apple Discussions!

If your iMac is still under warranty or AppleCare Protection Plan, you should not pay anything and there is no such thing as a "charge for Service Agreement".

Do not go first to a shop.
What you have to do first, is call Apple, get a "case number", and it's them who will give you the address of the nearest authorized repair shop, or the address of the least busy...

Good luck!

Would that be done during an "Erase and install"?


No. Boot from your system CD, open your disk utility, select your drive on the left, click on "Security Options.." on lower right, click on "Zero all data" and then erase. When it's done, install a new system.

Thanks Bmer,

I tried doing as you say, though I recieved a "Zero
disk failed" error with the message "Could not open
disk". I also tried doing a normal erase, it said
"Disk erase failed" with the message "Bad file
descriptor". I can't even see the hard drive as an
install target for the installer now!



Sound like that disk has major problems. You could try DiskWarrior on it, but I would contact Apple, tell them about the readings you are getting and see if they will send you a replacement drive. It's a serviceably part that you can replace.

Yes, a DIY HD would probably be a good idea. I don't know how to approach support, as I don't know how to reproduce the problem: about 15 minutes after my last post, the hard drive came up in Disk Utility, and I did a fill with zeros erase, and the computer is loading "fine" now, and neither Apple Hardware Test nor DiskUtility can see anything wrong with it. I don't get it 🙂

Thanks for the zero tip,
Douglas
