HARD DRIVE FAILURES?

Yeah any odd sound like clicking/high pitch noises are very bad news for hard drives. You would be lucky to be able to get any data off of there, but of course try and see if you can if needed. Then try to wipe the drive for security and chuck the sucker into the trash!

I HAVE LEARNED MUCH FROM YOUR SITE AND BY OTHER HELPFUL SITES! I HAVE BEEN REPAIRING COMPUTERS FOR FREE NOW FOR A FEW YEARS.

TWO QUESTIONS I HAVE ON HARD DRIVES:

WHEN WORKING ON A COMPUTER THAT HAS A LOUD SOUND (HIGH PITCH) FROM THE HARD DRIVE I ASSUME

THE DRIVE WILL FAIL SOON. IS THIS CORRECT AND IS IT BEARING FAILURE?

THE OTHER QUESTION IS:

WHEN THE BIOS SEES THE HARD DRIVE AND THE HARD DRIVE WILL NOT P0ST THEN THE HARD DRIVE IS BAD RIGHT? OR IS THE BOOT SECTOR OF THE DRIVE JUST BAD AND NEEDS TO BE REPAIRED? THIS HAS HAPPENED AFTER WRITING ZEROS TO THE DRIVE ABOUT TWO TIMES TO ME IN THE PAST. I HAVE WORKED WITH A FEW HUNDRED DRIVES NOW AND JUST WANTED TO HAVE SOME MORE INFORMATION PLEASE.
