Running badblocks in non destructive write mode and so far, so good (it's slow but it may comes from my drive). Did you test if there was a bad cable or faulty drive PSU ? Arnaud
Hi, 2011/9/1 Richard Zhu <richard.zhu@linaro.org>: > Hi Hector: > What's happen before "> [ 7.073106] EXT4-fs (sda2): re-mounted. > Opts: errors=remount-ro"? Here is my complete dmesg. The system seems to work fine, it is a 1.0TB WD10TPVT SATA disk in a case which provides eSATA and connected to mx53 LOCO with eSATA-to-SATA cable.
