Hi there, first time poster so please bear with me. Have a mbp, 2.0 ghz, 2 gig RAM, running Tiger. Froze on me yesterday, couldn't force quit. Turned on and off and am now stuck on grey screen with apple logo and a regular ticking sound every 2 secs which i'm sure is the hard drive. Will not start in Safe mode and single user mode and verbose mode do not work saying disk0s2 [some numbers] undefined. Ran Disk Utility and disk repair and got this error message: Error: the underlying task reported failure on exit. Tried resetting PRAM, no joy. Does it sound like my HD is finished? I have some stuff backed up but there are photos and some other stuff i would like to get off of it. Can anyone offer any help? I have downloaded Disk Warrior but cannot check anything until this evening. It is out of warranty, 18 months old.
