I have an Ubuntu installation which has a lot of hard drives. Two of these drives have hiccups and SMART is reporting errors. However, I cannot figure out how to determine which drive is ata1.00 and which is ata12.00. Is it possible to retrieve their serial numbers, as this would be easiest way to find the correct drives?

ls -l /sys/class/ata_port/ should show the link to PCI id. Then ls -l /dev/disk/by-path/ would tell you what /dev/* that that is assigned to.

Look at ls -l /dev/disk/by-path and find the sd* device that corresponds. Then look at ls -l /dev/disk/by-id for the model and serial number that corresponds to that sd* device.

You may find this helpful:

sudo lshw -class disk -short

(or try it without the -short but pipe it into less).

You can look at the output of ll /sys/block which shall give you something similar to

lshw -C disk

will get you drives, their product ids, and mount points.

*-disk:0                
       description: ATA Disk
       product: XXXX
       vendor: Seagate
       physical id: 0
       bus info: scsi@0:0.0.0
       logical name: /dev/sda
       version: JC4B
       serial: XXXYYY
       size: 931GiB (1TB)
       capabilities: partitioned partitioned:dos
       configuration: ansiversion=5 signature=0006ded4

You can then find their most recent mount info in /var/log/syslog, with something like (e.g. looking for disk /dev/sda)

cat /var/log/syslog | grep 'sda' -A 5 -B 5

for other info, you can also try

blkid

or

mount

If you don't know the device name but know the bus number of an IDE harddrive, and want to find out the serial number, you can do:

cat /sys/bus/ide/devices/0.0/serial

Where "0.0" is the bus number.

You want hdparm -i /dev/whatever.
