Koneessa on Ubuntu 8.04 ja kernelin versio 2.6.24-25.
Ennen samainen Western Digitalin usb:n kautta virtansa saava kovalevy pysyi mountattuna, eikä ongelmia ilmennyt.
Marraskuun lopusta (ehkä 28.11.) alkaen havaitsin virheen varmuuskopioinnin yhteydessä, eli sbackup ei pystynyt kirjoittamaan tälle levylle. Kun yritin katsoa levyn sisältöä ls-komennolla, sain pelkän I/O Errorin, mutta "sudo mount -a" onnistui mounttaamaan levyn taas ja kaikki toimi niinkuin ennenkin. Levy kuitenkin tippuu nyt päivittäin, enkä saa varmuuskopioita otettua..
Tässä tämän aamun antimia:
$ ls /media/backup/
ls: reading directory /media/backup/: Input/output error
$ sudo mount -a
mount: wrong fs type, bad option, bad superblock on /dev/sde1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Ja fsck.ext3 sanoi, ettei levyllä ole virheitä.
Tänään tuli ensimmäistä kertaa virhe tuon "mount -a" -komennon yhteydessä, mutta kun tein sen toisen kerran niin johan lähti toimimaan.
Tietääkö kukaan missä vika voisi olla?
