Why is my disk super slow after excluding it from spotlight indexing?
After removing my external USB 2.0 WD 1TB Passport from spotlight indexing right after starting indexing it is like super-slow now. After waiting a few minutes a can open single folders but copying any file takes an eternity. Is there a way to fix this problem? Already tried disabling spotlight and reindexing, but spotlight says that re-indexing takes about 13 days.
Already tried to backup the files on my Macbook but the drive is slow on that system too. My iMac runs 10.9.5 and my Macbook 10.10.5.
Any help appreciated.
MacBook (13-inch Mid 2010), Other OS, Yosemite 10.10
