Chyba s diskem v raidu - vadný disk, kabel.. ? (vyřešeno)

Hezký podvečer,

jsem v koncích, jelikož už po několikáté řeším jeden a ten samý stroj. Mám na debianu raid, kde jsou dva systémové disky, raid1, ty by měli být v pohodě. Donedávna tam byl třetí disk, 3TB jen jako datový, bohužel po tvrdým vypnutí se něco po.... Data se mi podařilo vytáhnout, disk naformátovat, projet pár utilitkama, které tvrdili, že disk ok. Tak jsem tedy disk vrátil, plus dovybavil stroj o čtvrtý disk, také 3TB a chtěl jsem opět je zrcadlit. Nakonec jsem si je v gparted hezky zarovnal, nechal jsem od konce cca 1GB místa pro jistotu (ani nevím proč tolik, asi mi to z těch 3TB přišlo akorát), vytvořil oddíly s ext4, vytvořil raidové pole, přidal disky, scanem vepsané v /etc/mdadm/mdadm.conf, kde to tedy funguje normálně i po restartu. Jakmile jsem ale /dev/md2 namountil někam (což šlo) se začali syncit a vše vypadalo v pohodě. Ale 68% je kritických, kde se to zastaví, rychlost spadne na 1K/sec

a konec, už zo semnou nemluví. O to horší je, co najdu v logu. Přikládám výpis.

Kde tedy sdc je ten disk, který předtím zkolaboval, o to mě to děsí víc. Podle logu ale co jsem dobu googlil, tak se většinou dle chyb jedná o problém s napájením disku, se sata kabelem, či řadič, ale prostě nevím co dál. Ten stroj převezu zítra domů abych na tom mohl pracovat a testovat, takže mám v plánu dát nový kabely a proházet napájení dísků i disky na řadiči, jestli bude nějaká změna. Nesetkal se někdo s něčím podobným ? Díky za každou radu a tip ! Přikládám i nějaké výpisy ze smartctl, já z toho nějak moc moudrý nejsem
