Like the original poster I cannot see the drive in Disk Utility but it does show up in System Information. I just started having this exact same problem with my FreeAgent Go drive which has always been working perfectly.

I have removed all USB drives, did a warm reboot, a cold reboot and even a reboot in safe mode: no joy.Įverything I have searched for has something about not being able to boot and the fix is repairing the disk via recovery console. I have checked my console logs and the only thing that comes up when plug in the failed drive is the error message Here's the kicker: I have another FreeAgent Go drive, exact same model and size as the one that dosen't work, and if I plug it in to the exact same dock, it works. It also works on another Mac (MBP 10.10.3) I go back to my iMac with 10.10.3 and nothing-it's like it dosen't exist. In fact, I plugged it into a Surface RT of all things and I was able to read and write with no problem. If I plug it into another computer, it works perfectly. However, in system profiler, it shows up under the USB, but not under the storage. This morning, I saw a message on my desktop (I didn't shut down) that I failed to eject it properly. I use it to keep files that I don't access on a regular basis and as a place to do "quick backups" of things like my Paperless library or my Lightroom Catalog. * Learn how to connect iPad Pro (11-inch) or iPad Pro 12.9-inch (3rd generation) to your computer.I have a Seagate FreeAgent Go drive with the optional docking station. If you have the same issue on another computer, contact Apple Support.
