rick_kimberlee you can read more here on reformatting with your Disk Utility:

Hope this solves your problem.

While Dave Sawyer had this to say:

Check the format of the disk. If it's NTFS, then Mac OS X can read it but cannot write to it. If that is indeed the case, then you have two options:

1) reformat the drive to FAT32 (use Disk Utility and choose MS-DOS). That will allow the drive to be read and written from both Windows and Mac OS X;

2) Try the drivers from Paragon, which claims to allow Mac OS X to both read and write NTFS volumes:

Hope this helps.

I was going to backup some files, but I'll just go get another HD for the Mac Mini.
