[QUOTE="sw55, post: 833081, member: 97075"] Hi, I am trying to format a new hard drive. It is an 80 GB USB Samsung drive. I open up Disk Utilitiy, click on Erase, select Mac OS Extended (Journaled) for the volume format, and press [Erase]. After a couple minutes I get the following message: Disk Erase failed with the error Input/output error A similar thing happens when I try to Partition, except the message is Partition failed. This is a new iMac with OS 10.5.6, 2.66GHz Intel Core 2 Duo, 4GB. I haven't used Macs that much, so it's quite possible I'm going about this wrong... How do you format a new USB hard disk? [/QUOTE]
