Took my mac formatted HD, transferred some images to it. Took the HD to my mom's and her Mac won't read it. Tells me to initialize. Tried it on both Macs she has and no go. Strangely the Disk Utility tell me the drive is NTFS formatted. Is it just corrupted and I need to reformat it? Or is there a way to fix it. I mean there is nothing I need to save off of it, I just want to show her some pics, drove 1hr to show them to her Any ideas?
