I connect it to my white Macbook (purchased late 2007, 2.14 GHz with 2 GB Ram), open Disk Utility. I click the single partition on the disk, choose "Mac OS Extended (Journaled)" for the Volume Format and leave the name as-is. When I click "Erase", I get the following error after only a few seconds: Volume Erase Failed with formatting external hard the error: The underlying task reported failure on exit If I try to create a new partition with the same filesystem, I get the following error: Partition failed with the error: File system formatter failed. This is the second disk I've tried this with - I sent the first one back to Amazon thinking it was defective, and they sent me a replacement. Obviously, it's unlikely that I managed to procure two defective drives, so I'm thinking there may be something wrong with my machine. Another note - I've tried doing the format with the disk connected to both USB 2.0 ports on my machine, as well as connected through a USB hub. The behavior is the same, regardless of how the drive is connected. osx hard-drive external-hard-drive formatting share|improve this question edited Mar 4 '10 at 12:01 community wiki 4 revs, 2 users 67%inkedmn add a comment| 5 Answers 5 active oldest votes up vote 1 down vote accepted Just for the sake of having an answer here, this is what ended up fixing the problem: Connected the disk to a windows XP machine Deleted the existing FAT32 partition that the device shipped with using Disk Management under XP. Connected it to the Mac, partitioned and formatted without issue. I won't make this the selected answer unless somebody upvotes it, and I'll make the question community wiki. share|improve this answer

I tried googling it but nothing seems to answer my question. I'm not trying to reformat the hard disk in my Mac but my external hard disk! I usually format my hard disks to clear the documents I no longer need. And I'll change it to ExFat but currently, whenever I plug in my hard disk on Windows, the whole system just hangs there.
