So here is my problem, i have gotten a
Unraid device sdn SMART health : 27-11-2019 06:40
Warning [TOWER] - udma crc error count is 1
Warning on 1 the 4 drives inside my new case.
Currently trying out unraid for the first time and while ussing
the binhex-preclear tool.
I got this warning on 1 of those 4 internal drives.
A while ago i order these four, 8 TB drives in WD elements enclosures from amazon.
Upon delivery i did do extended smart checks on them wenn connected to
a windows 10 pc over usb, no faults where found back then.
Months later i ‘‘shucked’’ them (remove from an external enclosure, so they might be used internally).
Two didn’t work with SATA cables wenn connected to the unraid server, the other two did.
(i beleave this is a third pin reset issue)
And 1 of those drives that didn’t work with SATA is the one with the error.
All 4 drived are now hooked up to 1 of the backplanes in a Silverstone C381 case.
Ussing a Silverstone branded: Mini-SAS HD SFF8643 cable this then
connects to a Lsi/broadcom SAS 9300-8i Host Bus Adapter, that is inserted in a
Asrock Rack X470D4U motherboard pcie slot.
What am i supposed to do with that:‘udma crc error count is 1’ warning ?
Now i have googled this obviously but most advice amounts to changing the SATA cable and that obviously doesn’t apply here.
And i also read that another option is that it represents a bad sector.
But smart reports:
So i assume it doesn’t have a bad sector ?!?
I am a clueless noobie, your help would be much appreciated.
