Você pode usar valores inteligentes: por exemplo:
smartctl -a -d 3ware,2 /dev/twe0
Qouting the manpage of smartctl:
Under Linux and FreeBSD, to look at ATA disks behind 3ware SCSI RAID controllers, use syntax such as:
smartctl -a -d 3ware,2 /dev/sda
smartctl -a -d 3ware,0 /dev/twe0
smartctl -a -d 3ware,1 /dev/twa0
where in the argument 3ware,N, the integer N is the disk number (3ware ´port´) within the 3ware ATA RAID controller. The allowed values of N are from 0 to 31 inclusive. The first two
forms, which refer to devices /dev/sda-z and /dev/twe0-15, may be used with 3ware series 6000, 7000, and 8000 series controllers that use the 3x-xxxx driver. Note that the /dev/sda-z form
is deprecated starting with the Linux 2.6 kernel series and may not be supported by the Linux kernel in the near future. The final form, which refers to devices /dev/twa0-15, must be used
with 3ware 9000 series controllers, which use the 3w-9xxx driver.
Note that if the special character device nodes /dev/twa? and /dev/twe? do not exist, or exist with the incorrect major or minor numbers, smartctl will recreate them on the fly. Typically
/dev/twa0 refers to the first 9000-series controller, /dev/twa1 refers to the second 9000 series controller, and so on. Likewise /dev/twe0 refers to the first 6/7/8000-series controller,
/dev/twa1 refers to the second 6/7/8000 series controller, and so on.
Para algumas ideias sobre a sua pergunta:
Isso pode ainda não ser um problema completo com o HDD / SSD, mas sugiro alterá-lo o mais rápido possível.
Faça backups se ainda não o fez!
Você pode verificar se há algum problema com algo como:
e2fsck -fv /dev/sdX
Se você vir setores realocados dentro do smart, você deve alterar o drive na minha opinião.
