So far there is no problem for me to write and read iPhoto library into NTFS external hard disk. However, when I try to open the iPhoto library in Photo, it show the volume format is not supported ? How could it be like it can support iPhoto but could not support Photo ?
MacBook Pro (Retina, 13-inch, Late 2012), OS X Yosemite (10.10.3)
Both the iPhoto and the Photo's library must be on a drive formatted Mac OS extended (journaled) - NTFS was not supported in iPhoto either - if it worked you were lucky and your luck has now run out

LarryHN, The external hard disk i'm using is Seagate Back up Plus, which include Paragon NTFS for Mac. Therefore , I am able to read/write with macbook and so far no problem with iphoto Library and even now. It only don't work with Photo app.
iPhoto needs to have the Library sitting on disk formatted Mac OS Extended (Journaled). That you can write to the disk doesn't matter. You can also write to several other disk formats, but having the Library on an inappropriately formatted disk risks library corruption and data loss. Later versions of iPhoto would not allow creating a library on these disks, and neither will Photos. You need to move the Library to an appropriate location.
Photo could not read iPhoto Library in NTFS
