Unraid Error

I have been running unraid on an old desktop PC for a couple years now for general back-ups. Updated to version 6.7.2 a couple weeks back without issue. I believe the hardware is:


MB: Asus P5B delux, 8gb Ram

CPU: Intel Core 2 Duo e6600 if I recall correctly

Drives: 3 seagate barracuda 4tb drives (1 for parity other 2 data), n old 1TB and 320GB seagates for data, and a 250gb SSD for cache


Today after initiating a few file transfers I was sent several errors stating that the parity was not valid and then that drive 1, a 4tb seagate had errors.  I briefly started a read check but stopped it as the error count of drive 1 was increasing rapidly appearing as though the entire drive was having errors. 


I have limited programming experience and the system has been running mostly on autopilot for sometime now with occasional parity checks so I just don't recall much about how to properly interact with and troubleshoot as I did when I was first setting it up a few years back. I have not changed or attempted anything else since the error. 


If anyone might be able to help it would be greatly appreciated. Thanks

No SMART for parity or disk1. 


Check all connections, power and SATA, both ends including any power splitters.


Then post new Diagnostics.

After 2 reboots and some sata and power cord jiggling and re-seating all drives are back up.  So I suppose it may have been loss of data or power from the Mobo which may just finally be showing it’s age with finicky ports. Everything is backed up but I will have to work on a replacement. 


Thank you very much for the help!
