badblocks -nvv /dev/sda -o badblocks.logPokud smart ukazuje, že jsou sektory realokované, tak je ti to samozřejmě na nic, protože jsou realokované, tudíž nepoužívané :). Taktéž se mi několikrát stalo, že obyčejný "-nvv" (nedestruktivní kontrola disku) neobjevila úplně vše, ale destruktivní kontrola ano (zneškodní všechny data na cílovém hdd):
badblocks -wvv /dev/sda -o badblocks.logOsobně to dělám tak, že provedu long smart test, pak badblocks v destruktivním režimu a pak opět smart test, abych měl něco na porovnání.

Vidím to ale pořád jenom na bramborovou medaili, protože kvůli těm ostatním diskům (jeden je úplně stejný jako ten testovaný), mi prostě NAS server zprávy neposílá a nevyhrožuje ztrátou dat. Mám tomu disku zase začít věřit?

NAS server (Synology DS410j) jsem rozebral, vyčistil, disky vyjmul a zase dal na místo (to jsem měl udělat na začátku). Poté jsem zase zařadil disk do raidu a normálně ho používám. NAS server přestal na disk nadávat.
Nafouklých kondenzátorů jsem si nevšiml. Kabely se vyměnit nedají, protože tam žádné nejsou. Tedy nějaké asi ano, ale jsou nestandardní, zabudované. Disky se prostě jenom zasunují (a přišroubují, což mám poctivě udělané). NAS server je po celou dobu své existence napájený z UPS.
Každopádně děkuji za spolupráci Maxovi i tobě. Chystal jsem se sepsat toto shrnutí, ale nemohl jsem se k tomu pořád dostat.
Btw: otázka ze subjectu zůstala nezodpovězena, ale měl jsem kliku, na tom druhém disku, který se fakt položil, jsem přišel pouze o data v jednom bezvýznamném adresáři, která po přeinstalaci stejně ztratila význam.
