Hi, A few days ago suddenly I can't mount /root because: 2014-07-17T03:01:17.500184+08:00 linux kernel: [16528.736353] ata1.00: failed command: WRITE FPDMA QUEUED 2014-07-17T03:01:17.841313+08:00 linux kernel: [16529.077363] end_request: I/O error, dev sda, sector 59764644 After command completion occurred, registers were: ER ST SC SN CL CH DH -- -- -- -- -- -- -- 40 51 08 84 ef 8f e3 Error: UNC 8 sectors at LBA = 0x038fef84 = 59764612 1 Raw_Read_Error_Rate 0x002f 100 100 051 Pre-fail Always - 2847 But: 196 Reallocated_Event_Count 0x0032 252 252 000 Old_age Always - 0 Google says it is the hardware problem, but after a reinstall, my computer still works...and actually the disk is less than 2 years old.. Error 19579 occurred at disk power-on lifetime: 12857 hours (535 days + 17 hours) When the command that caused the error occurred, the device was active or idle. Can anyone help judge this? Do I have to replace the disk? Marguerite -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
