Nas freezing on writes - how to locate broken drive
Hi, I think I have a drive that's on its last legs but I am not seeing any SMART errors. Anytime a large file is written to it, the whole machine freezes. What is the best way to determine which...
Seeing your hardware is out of warranty and you have a broken drive tray you are probably best to buy the RND4TRAY1 e.g. from Amazon.

Power down the NAS and remove the drives (labeling by slot). Then test them in a windows PC with vendor tools (seatools for seagate, lifeguard for western digital).
You can use a SATA->USB adapter or dock if your PC doesn't have a SATA connector you can use.
Thanks for the lateral thinking! I was trying to do it with the server still running.
So you discovered which disk was the problem?
Not sure yet but one of the drives was showing an "offline uncorrectable sector" which was bad enough for CrystalDiskInfo to give it a Yellow warning. However, all the drives passed the SeaTools "Short Drive Self Test" and the "Short Generic" tests. I replaced the one drive that has an error and it is currently rebuilding.
Once it's rebuilt I will retest again. The problem is writing -- when I create a tarball of some directory, it will just hang so I assume that reading is OK - it's writing that has the problem. I'll keep you posted!
Also, do you know if this older NAS will support 8 or 10tb drives?
