Eu tenho as seguintes mensagens no console
Eles dizem:
ata1.00: status: { DRDY ERR }
ata1.00: error: { UNC }
blk_update_request: I/O error, dev sda, sector 1476687273
usbhid 6-1.2.3:1.1: couldn't find an input interrupt endpoint
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata1.00: irq_stat 0x40000001
ata1.00: failed command: READ DMA EXT
e assim por diante.
As perguntas são:
1) O que esse erro significa? Isso apenas significa má superfície do setor?
2) Posso consertar uma superfície ruim? O Drive está quase vazio e não vejo motivo para jogá-lo fora.
3) Por que o número de setores é geralmente o mesmo? (às vezes ocorrem alguns números de setores diferentes)
4) Por que esse erro não aparece sempre, mas provavelmente quando eu ligo meu chaveador KVM? (é visto pelo prompt de linha de comando rolado não muito longe)
5) Como o USB está relacionado? É apenas uma mensagem não relacionada interlevisada?
Eu tentei executar fsck criando
touch /forcefsck
e também correu
smartctl -t long
sem resultado aparente. Também o que significa isto:
$ sudo smartctl -l selftest /dev/sda
