Hi @herbert_wu, we’ve just run across this same problem. May I ask how long it took for you to defrag the one file? I’m defragmenting it with defraggler but it has been stuck at 0% for an hour now.
It seems that our disk is very fragmented (97%). It sucks because our game server has now been down for the past 12 hours and counting and I’m not sure if this will resolve the issue.
Does anyone have any other tips/suggestions for this issue?
