Need to reformat external hard drive for time machine?
We recently purchased an external hard drive for our family iMac after we had to have a new hard drive put in. We picked up a Western Digital 1tb My Book ( http://www.wdc.com/en/products/Products.asp?DriveID=725). I set up the external hd with time machine and all was fine for about a month.
An error message of "The backup volume is read only" started appearing. I attempted to repair the disk through these directions http://support.apple.com/kb/HT3275#1 but when I was trying to follow the steps, I think I disconnected the external hd without dismounting it, so now I'd assume I need to reformat the external hd. I can't seem to find instructions on how to do this. Where should I look for reformatting my external hard drive?
Any other tips or suggestions would be greatly appreciated.
