I recently added a refrubished 25GB ATA harddrive to my G4 as the orig. was grinding so bad i was afraid to loose it.


The diskutil recoginized the drive however only displays 12MB of disk space available to play with. Anyone know how to remedy this?

    Have you tried reformatting the drive and doing 'Get Info' on the newly formatted HDD?

    I tried however the disk utiltiy only shows 12MB can be formatted. Is there a way to do it from command in terminal?

    Did you try erase the disk instead of the volume? or try to repartition the disk in case issue is with volume?


    In terminal you can use the diskutil command:

    diskutil erasedisk

    Usage:  diskutil eraseDisk format name [[APM]Format|[MBR]Format|[GPT]Format]


    Completely erase an existing whole disk.  All volumes on this disk will be

    destroyed.  Ownership of the affected disk is required.

    Format is the specific file system name you want to erase it as (HFS+, etc.).

    Name is the (new) volume name (subject to file system naming restrictions),

    or can be specified as %noformat% to skip initialization (newfs).

    You cannot erase the boot disk.

    Example: diskutil eraseDisk JHFS+ UntitledUFS disk3

    This did not work. It's higher up i think.

    Can you actually add more than 12MB of files to the HDD? If you format using Gparted does it exhibit this problem?

    Yep, If Iformat using Gparted it exhibits this problem.
