    Disk Failure Issue
    I started the process of Zeroing out an internal Hard Drive of my MacPro 1.1 and during the process it failed.

    Now when I go to disk utility to restart the process, I get the following message when I select the drive: ''This drive has a hardware problem that can't be repaired. Back up as much of the data as possible and replace the disk. See an authorized Apple dealer for more information.''

    How would I go about repairing this drive and reformatting it?

    Thanks for your help guys.

    G'day and welcome to the forums.

    Disk repair tools such as DiskWarrior cost over $120.00. Simply put the money towards a new Solid State Drive
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Ouch - what process did you use to zero out your drive? In the old days zeroing out meant a low level format which is not recommended on today's newer drives. Just wondering.

    Recommend using Onyx to clean your Mac.

    He probably used the older Disk Utility secure erase feature. It could do a one time pass, or more, and write ones and zeros over the data. The current version of Disk Utility no longer provides for the secure erase feature. I don't believe it's possible to low level format a drive without special factory software, but who knows?

    Imarty_surf, if you did this because you were having problems with the HD then it was probably the wrong thing to do. I have noticed that when a HDD is nearing the end of it's life rewriting it, upgrading the OS or erasing it will sometimes tip it over the edge. I agree with harryb2448, dont waste tme trying to save it, back it up and spend the money on a new drive, preferably a SSD it will give your device new life.
    I used to be conceited but now I'm perfect.

    Hey guys,
    thanks for answering. I did this initially because I was going to set it up as a RAID and I read that it was a good Idea to zero it out but I guess I won't do that anymore.....

    Luckily I did not loose any data I had backed it up before hand...
