WD Purple hibas vagy mas a baj?

UPDATE: mult heten megkaptam a cserevinyot (mivel megingott a bizalmam a Purple-ben, egy Redet kertem helyette, remeljuk ezzel mar nem lesz gond)

vettem nemreg egy WD Purple-t (a Red-et vagy ezt ajanlottak egy masik forumon, vegul a Purple-t valasztottam...)
tisztaban vagyok vele hogy megfigyelorendszerekhez ajanljak elsosorban, nekem otthonra NAS-ba kell gyenge torrentforgalomra illetve Time Machine backuphoz (vagyis jellemzoen kb. folyamatos, kis sebessegu iras/olvasas). Egy Sharkoon kulso hazban uldogel.

Viszont erdekes hibakat talaltam a rakotott Raspberry logjaban.
Ezen nekibuzdulva raeresztettem egy badblocksot egy desktop gepre kotve (amugy ezzel kezdtem volna, de olyan baromi sokaig tart, hogy inkabb nekialltam atmasolni ra a tobbi kulso vinyorol a cuccost, gondolva hogy ha baj van ugyis kibukik - hat ugy nez ki bejott :D).
az elso kb. 80%-ig siman elmegy kb. egyenletes tempoval, onnantol viszont nagyon durvan belassul, jelenleg itt all, az 'elapsed' az 5-10 percenkent lep elore, a szazalekjelzes lenyegeben mozdulatlan:


$ sudo badblocks -svn /dev/sdi

jelenleg: Testing with random pattern: 83.19% done, 48:29:45 elapsed. (0/0/0 errors)

Szoval, most rossz a vinyo, elkepzelheto hogy a rack-kel van baj, netan valami beallitas/kernel/stb okozza a gondot? (ezek a tippjeim, csokkeno valoszinuseggel :D)
