ez nem scsi? mert akkor nézd meg az "scsiinfo -a /dev/sda" paranccsal hogy a grown táblában van-e bejegyzés. a manufacturer táblában 100% van azt ne nézd :)

Nagyon koszonom :) Ez tenyleg ertelmezhetobb infot adott. A grown tablaban csak egy bejegyzes volt, remelem, ez mar eleg ok garis cserere ;)

Hi,

Van egy Samsung SP0411N 40 gigás vinyóm, eddig jól ment, de az utóbbi napokban érdekes dolgokat produkál (FreeBSD 5.3 megy a vason).
fsck /dev/ad0s2a-ra néha azt mondja, hogy OK minden, máskor meg DMA olvasási hibák jelennek meg a konzolon (egy, kettő, vagy négy):
ad0: FAILURE - READ_DMA status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=25834536
CANNOT READ BLK: 2016

ad0: FAILURE - READ_DMA status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=25834606
THE FOLLOWING DISK SECTORS COULD NOT BE READ: 2086,

A smartctl szerint a Reallocated_Sector_Count = 0, viszont a DMA hiba benne van a logban:

SMART Error Log Version: 1

Lefuttattam a Samsung gyári tesztprogiját (hutil.exe), ami a felületellenőrzést ~33%-ig csinálta onnan pedig egy órán át köpte kifelé, hogy Error: LBA xxxxxxxx. Aztán meguntam és leállítottam.

Szóval, ****om sincs, hogy mi ez a hiba, vagy mi okozhatja :?:. Ráadásul a három tesz nem ugyanazt az eredményt szolgáltatja.
Még garis a vinyó, úgyhogy kicseréltethetem újra, de nincs nagy kedven újrahúzni a rendszert.

DMA hiba az átvitelnél keletkezik, BADSECTOR pedig a lemezen...
nem értem az összefüggést :)

bocs nem tudja valaki hogy amíg hde-ként értem el a sata vinyót addig adott értékelhető eredményt a smartctl, de mióta sda-ként érem el, a válasz:
"Device does not support SMART"?
a kernel, vinyó nem változott, mindössze a libata rétegen éri el mostmár.

Ez világos, de miért mindig ugyanazon a helyen jelentkezik a hiba :??

( marczi | 2004. 09. 20., h – 17:35 )

A smartctl az alábbi erdeményt adja. Jól gondolom, hogy a test log alapján egy hibás szektor tanyáz a vinyón?
