jesseasi Posted January 16, 2018 Share Posted January 16, 2018 I am looking to purchase some 10TB drives to upgrade my 24 drive unraid system. Ideally once I have a 10TB parity drive in position I could add a few more and pull out 7-8 of my 10 year old 1.5TB drives. The case is not that old though. Probably 4-5 years. As documented here - https://www.hgst.com/sites/default/files/resources/HGST-Power-Disable-Pin-TB.pdf . Many new drives are coming with a new Power Disable Feature. Apparently you need a power supply that supports this feature or you buy an adapter than removes Pin 3. However my older Norco cases has a back plane that supplies all the connections for the drives. Does anyone know if I get drives with this Power Disable Feature - will they work? I prefer not to have to cut wires or put tape over pins. If you are in the know - please let me know. Thank you.

Chris Pollard Posted January 17, 2018 Share Posted January 17, 2018 (edited) Sounds like you just need to check if pin 3 is supplying 3.3v if it is, you can't use those drives without a hack. Edited January 17, 2018 by Chris Pollard Quote Link to comment

If you are buying HGST drives they sell ones with or without power disable feature. Edited January 18, 2018 by TUMS Quote Link to comment
jesseasi Posted January 20, 2018 Author Share Posted January 20, 2018 Ok. well if you have a Norco 4224 older model - not sure when they updated them...but when installing one of these power disable drives - they do not spin up. Now I need to find a hack? an adapter? or see if Norco can sell me an updated backplane? Anyone here can point me in the right direction? Quote Link to comment

In short, it's meant for this type of application. Quote Link to comment
jesseasi Posted January 21, 2018 Author Share Posted January 21, 2018 Well that was super easy. I bought some Tapcon tape - arrived today - took me 10 minutes with some reading glasses and tweezers to cut and apply the tape. Plug it in and spun right up! 1 Quote Link to comment
