Sep 12, 2015 2:22 AM in response to LarkinMby lescornwell,Looks like the same issue as we dealt with here: Photos library will not open from external hard drive
Launch Disk Utility and check how your external HD is formatted. If not MacOS extended (journaled), reformat. I assume the ext HD is connected through cable with your Mac (USB, Firewire, Thunderbolt)?

Sep 12, 2015 2:31 AM in response to LarkinMby léonie,Is your external drive correcly formatted? The MacOS Extended format is necessary, if you want to use the drive with iCloud Photo Library and ensures, that no copy errors will occur when copying from your system drive.
Try to prepare the drive as described here for iPhoto. That will work for Photos as well: iPhoto: Sharing libraries among multiple users - Apple Support
Move the Photos library to a volume where permissions are ignored. That will prevent permission and ownership errors when copying.
- Connect an external USB, FireWire, or Thunderbolt drive which has enough free space to contain the library.
- Select this drive in the Finder.
- Choose File > Get Info.
- In the Info window, find the Sharing & Permissions section. You may need to click the disclosure triangle to see the details for this section.
- Click the lock in the lower-right corner of the Info window. Enter an administrator name and password when prompted.
- Select the option to Ignore Permissions on this volume (usually selected by default).
- Copy your iPhoto library to this drive.
Important: If you've selected this volume for use as a Time Machine backup, you will not be able to select the option to ignore permissions on the same volume. Select a different volume for the destination of your shared iPhoto library.

Sep 12, 2015 2:35 AM in response to léonieby LarkinM,Thanks for this, but I don't get anything past step 4 in the instructions. No lock icon appears and when I open permissions, it simply says I can "read and write" but does not give me any other options to edit or change.

Sep 12, 2015 2:42 AM in response to lescornwellby LarkinM,Thank you for this. My utility says, "Windows NT Filesystem (Tuxera NTFS)" for the format. Yes, I am connected by a cable. I have other data on the external. If I reformat, won't it erase everything? I don't have a current way to back up my external in that case. I would have to buy another external drive to do this.

Sep 12, 2015 2:48 AM in response to LarkinMby léonie,s, "Windows NT Filesystem (Tuxera NTFS)"
Then your drive is not suitable to host a Photos Library. And you cannot enable "Ignore ownership" on it.
Reformatting the drive will erase it. So you need to save the data elsewhere, before you reformat.
Do you have a different drive you could use? Do you need to use your drive on a Windows system as well?

Sep 12, 2015 3:38 AM in response to LarkinMby lescornwell,As I suspected, and as Lėonie has explained. Wrong format for Photos library.
It is true, though, that you will have to move the files you want to keep off the Win-formatted drive before reformatting, because that process (in Disk Utility called "erase"!) will erase the contents.
External storage is not expensive these days. You can never have enough.

Sep 12, 2015 7:17 AM in response to LarkinMby LarryHN,Yes reformatting will erase the drive
and if you have a NTFS formatted drive so you can use it on both a Mac and a PC you will not be able to use the reformatted drive on the PC
Depending on your cross platform needs you can either backup everything on the drive and reformat it using Disk Utility and then reload the data
or
you can purchase a correctly formatted drive (Mac OS extended (journaled) ) with a USB, FireWire or Thunderbolt connection and use it - Apple and Other world computing are the wo vendors I personally use for drives

Sep 12, 2015 2:02 PM in response to LarryHNby lescornwell,A quick question, Larry: does Apple (still) sell external HDs? I buy a particular type of LaCie nowadays (Quadra series). Only lost one in the 6-8 years that I'm using this brand and particular type, and I have all my external drives regularly checked by DriveGenius.

Sep 12, 2015 4:01 PM in response to lescornwellby LarryHN,As far as I know only TimeCapsules - I have one at each house for WiFi and TimeMachine - but you use them as an external hard drive too if you want - I use OWC for stand alone hard drives
