Unable to initialize new 1TB drive
Just installed a 1TB Drive but neglected to initialize before installation. Have been getting the flashing folder with ? mark.
However, I have an external USB flash drive 8GB with El Capitan installer mounted as external drive. That (magically) has allowed me to get to Disk Utility and see what is happening.
Disk Utility tells me the drive ST1000LM014-1EJ164 Media is Uninitialized. Other details are: Location-Internal, Capacity-1TB, Connection-SATA, Child Count-0, Partition Map-Not Supported, Type-Disk, SMART Staus-Verified, Device-Disk0.
Running First Aid is Successful (whatever that means..).
I've tried to reformat using the Erase function (choosing Format: OS X Extended (Journaled) and Scheme: GUID Partition Map) without success. The message I receive is "Erase process has failed. Press Done to continue." The details tell me the following: Unmounting disk. Wiping volume data to prevent future accidental probing failed. Operation failed ....
Any advice on what to try? My only thought is to uninstall the drive, initialize it as an external disk on another machine, and re-install. Before I do that, I'd welcome your advice.
Es esta una buena pregunta?
