Unmountable external hard drive, read-only - 08/07/15 03:32 PM
I was thinking about using a second, backup hard drive when I found this old one in my stuff, a Seagate (I think) in an OWC FW400 enclosure. No off button. That always bothered me.
I erased the drive with Disk Utility. When I came back after an hour, there was an error message which I don't recall. My computer had gone to sleep in the meantime and I had to log in again, but it looked like the job was done. I had zeroed the drive and it was empty.
But now I couldn't mount it. Disk Utility after a while could read it and informed me through Info that the drive was now read-only, not writeable. All the options in Disk Utility are greyed out. I can't do anything to this drive unless I can mount it.
I will likely buy one. All I need is something cheap like a 200 MB Firewire drive. Hard to find, as it turns out, Firewire being a thing of the past. I will search ebay, but I still would like to solve this problem. I spent a lot of time on Google reading about unmountable drives but couldn't find an answer.
