Ok thank you

Ok, thank you for your time. I will see if everythings work fine in time. Did i mark this as revolved or i wait a little ? (And sorry for my bad english )

Ok, i've remove all extension, max 3 disk on each alimentation cables, Disk connected to LSI with this cable : https://www.amazon.fr/gp/product/B07C13922C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and this https://www.amazon.fr/gp/product/B07BZCXM84/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 and two directly to the mother board. tower-diagnostics-20241219-1643.zip

ok, i will try to remove alimentation extension and re-connect HDDs to the LSI and see if errors disappear.

Don't know, i've tried change alimentation and sata cable. I only have max 3 disk on one alimentation. Could it be because i have to use power cable extension as mine are too short for reach all disks ?

yes, sorry. After the issues, i've connected some disk to this : https://www.amazon.fr/gp/product/B098QPJJFF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 For now, it's seems working for only 6 disk with two parity. Parity-Sync in progress is in progress.

Thank you for your replies. tower-diagnostics-20241219-1240.zip

Good morning, I'm just starting to use unraid. I set up a NAS with: - Gigabyte Z590 Gaming X ATX Motherboard for Intel LGA 1200 CPUs https://www.amazon.fr/gp/product/B08XNKLGS4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - 64 GB of RAM - Intel I510400f - Card SAS9211-8I 8-port SATA + sas Pcie 2.0 6 GB memory card https://www.amazon.fr/gp/product/B002RL8I7M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - Power supply: Tecnoware 850W Modular Power Supply for PC Gaming - https://www.amazon.fr/gp/product/B08K964Y3J/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 I have 9 hard drives of 10 TB so 2 for parity. But after each reboot or randomly I have I/O errors on the disks (all randomly). I tried to change the sata cables and power cables several times. I'm out of ideas. If you can help me, I will be grateful.
