Or WHAT I NEED TO DO to save this 1 TB Hard Drive!?

For help tell us about your Mac.

For help tell us if you have the system install DVD or the operating system DVD.

Verify Disk Permissions

Ehen I try VD Permissions I got this message:

Disk Utility internal error. D U has lost its connection with the Disk Management Tool and can not continue.

I stop and relunch... twice... the same!
What is Wrong?

Thanks!

Disk Utility did not repair thus you have a dead hard drive. Time for a new one. As a last resort, you have an OS on a second partition, try booting and holding down the Option key in order to see if you can access this partition. If this works, go to System preferences > Startup Disk and select that partition by clicking on it.

Click to expand...

I did that and after restarting I got the same Grey screen w/ ? mark. I did Disk Utility check and there is no more HD info (like before w two partitions)... only my DVD w/ OS Instalation disk!... Deffinetly dead HD, correct?!....

Thanks!

Yep. The screen with a ? on startup means it can't find an OS to boot and load.

Solved!

Thanks a lot for all Help,
I order a new HD! !
