I am trying to format a brand new 3TB extrnal drive to Mac OS Extended using Disk Utility under Mountain Lion, so I can hook up my Stardom Safe Capsule to my Time Capsule and increase its storage capacity.

 

I am getting the same error every time: "Wiping Volume Data to Prevent Future Accidental Probing failed" when using Disk Utility Erase function. And then the process stops.

 

I do not have an older version OS startup disk, so I can not revert back to Lion or earlier.

 

 

 

What should I do ?

 

 

 

Many thanks in advance.

    Instead of erasing the current partition try removing the partition and create a new one Mac OS Extended (Journaled).

     

     

    In Disk Utility highlight the 3TB volume and go to Partition tab on the right pane

    remove the current one with "-" and add a new one with "+"

     

    Post back with any issues.

    If you're trying to format the HD, select the media in Disk Utility and partition it to however many partitions you want using the GUID option and the Mac OS Extended (Journaled) Format. How is the external drive connected to your Mac?

    Thanks for the pointers, but this did not work for me either. I am getting the same error message. I am seeing that that the bar in the right low corner keeps on: "Unmounting the disk" until the error message appears.

     

    When I use the "Erase" function, I get the "Unable to write the last block" error.

     

    I am connected to the drive through USB.

     

     

     

    Any other options?

    Why are you trying to Erase? Creating the partition erases what was on the disk before or at least the directory which made the prior contents accessible.

    Both "Erasing" and "Partitioning" are giving me errors and not the desired result. I am just trying to format a new disk, so I can use it. There is nothing on it.

    I checked the website for that HD and it was presented as ready for the Mac, not simply "compatible with" as is often said about FAT or exFAT formatted drives that are really made to work with Windows first. You might consider calling the manufacturer and asking them since the drive shouldn't resist partitioning or erasing.

     

    Update: Umm, sorry; I didn't realize their closest phone number is in Taiwan.

    Uh... I fixed it somehow myself..... there is a switch at the bottom of the safe capsule. There you can decide whether you want two independent disks, or one redudant one.

     

    The disk partitioned fine once the switch was set to redundancy. Weird, but I got the result I wanted, an extension to the Timecapsule drive.
