Hard drive not seen

bundu · 07-15-2008, 05:42 AM

Recently I had PC flash disk in my Macbook Pro which started giving me problems with some files. My computer then did not start at all and I reinstalled the system. A day later still having problems. I checked with disk utility. And I could not repair it because of an 'invalid node structure' and 'invalid record accounts'.

So I tried to restart out of disk utility and then all of a sudden I can not see my hard drive at all. It has simply vanished completely.

Any one that might be able to help it would be appreciated.

thanks in advance

Hey mate,
first of check cables...
Then find out what make/model is your HDD...
Download from manufacturers Web Site testing tools and test your HDD for possible bad sectors... [this is off course of your system sees HDD]...
Hope this will help you mate...

It sounds like the drive is going bad. At this point, I'd take it to an Apple store or repair center and let them look at it.

I'm not sure if your mac supports SMART disk or has a SMART disk but it probably does. Check in system profiler under the hard disk or boot to the CD in disk utility and you can see the hard drive then you can check you SMART status which can tell you messages about your hard drive like "failing" or "good". I would check both to be sure sometimes system profiler will not report the correct condition.

If it is failing most important thing is to backup you data.

Usually invalid nodes are bad news, call apple, buy applecare if you qualify and let them deal with it..
