I have been using my 2008 MyBook on my Mac for about 16 months, intermittently, without a hint of problems, and suddenly when I connect (using either a 3 foot usb cable or a 3 foot firewire) I get “would you like to format this blank disk?” messages.
I can see the disk icon in the disk utility window but there is no recover option, only a “format” option.
I am using OS 10.6.7 on an iMac.
