Mapping ata2.00 (ataX.00) to a device

linux icon 19On occasion you may get a nasty error like this (BadCRC generally means bad sectors):

[4530467.649165] ata2.00: exception Emask 0x10 SAct 0x60000000 SErr 0x280100 action 0x6 frozen
[4530467.649608] ata2.00: irq_stat 0x08000000, interface fatal error
[4530467.650043] ata2: SError: { UnrecovData 10B8B BadCRC }

But the problem is mapping the drive ata2 to an actual disk drive device. This can be achieved by running this command:

 ls -l /dev/disk/by-path/

The output will show you the mapping from ata2 to the actual device on the system:

lrwxrwxrwx 1 root root 9 Aug 7 09:35 pci-0000:00:17.0-ata-1 -> ../../sda
lrwxrwxrwx 1 root root 10 Aug 7 09:35 pci-0000:00:17.0-ata-1-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 Aug 7 09:35 pci-0000:00:17.0-ata-1-part2 -> ../../sda2
