BoySherman Posted February 13, 2022 Share Posted February 13, 2022 I think I've tried everything I'm stumbled across in the support forums, but I'm stumped. Back story; I had an old broadcom SATA card. I was experiencing VERY slow transfer on parity sync (< 1mb/s). Funny stuff started to happen with docker config files, disappearing files etc etc. So, to remedy this, I purchased 3x "serial Attached SCSI controller: Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)" After installing these cards, parity sync is great, and back to what I think is expected (~150mb/s). However, *some* of my somewhat newer/larger hard drives are throwing up errors at an alarming rate. Some of them even after a complete format (there is nothing of real importance, so I was happy to just delete data in some cases). I have done the following (and probably more); * ran a checkdisk -L on every disk. * completely formatted some (still seeing errors) * Ran a memtest (clean). * removed memory modules down to a single chip for now * Reset all of the controllers in their slots, ensured sata cables were all secure. * If a hard drive failed, moved it onto another controller where I know the connection is sound (I have hot-swappable drives) * seems like hardware faults, but I don't understand how it could have occurred to many at once, the odds just don't add up. (especially after formatting). Diagnostics attached. Any ideas? tower-diagnostics-20220213-1026.zip Quote Link to comment
BoySherman Posted February 13, 2022 Author Share Posted February 13, 2022 I should make note of one thing I forgot... all of the drives power are daisy changed off of a single supply cord (with splitters). Not sure if that's of any concern. Quote Link to comment

BoySherman Posted February 14, 2022 Author Share Posted February 14, 2022 Boom! Yup, that was it. Split the 6x4 backplane into two, and the funny behaviour ceased... thanks! 1 Quote Link to comment
