How do I find out which motherboard SATA port number is an HDD connected to?

We want to build a hdd copy software based on physical identification of SATA.

lsscsi --verbose will provide output similar to this:

[0:0:0:0] disk ATA TOSHIBA THNSNH12 HTRA /dev/sda dir: /sys/bus/scsi/devices/0:0:0:0 [/sys/devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0] [1:0:0:0] disk ATA WDC WD2003FZEX-0 01.0 /dev/sdb dir: /sys/bus/scsi/devices/1:0:0:0 [/sys/devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0] [2:0:0:0] disk ATA WDC WD3001FAEX-0 01.0 /dev/sdc dir: /sys/bus/scsi/devices/2:0:0:0 [/sys/devices/pci0000:00/0000:00:1f.2/ata3/host2/target2:0:0/2:0:0:0] [3:0:0:0] cd/dvd Optiarc DVD RW AD-7280S 1.01 /dev/sr0 dir: /sys/bus/scsi/devices/3:0:0:0 [/sys/devices/pci0000:00/0000:00:1f.2/ata4/host3/target3:0:0/3:0:0:0] 

which provides the ataN port which can matchup with information found in the syslog. Useful if you are trying to determine where an error is coming from .

Edit: If which lsscsi provides no output you need to install it:

sudo apt-get install lsscsi 

Further Edit:

This probably goes without saying, but of course you can filter the output with grep to locate what you are interested in for instance if you find an error like ata4: status: { DRDY ERR } you could simple issue the command

lsscsi --verbose | grep -P1 -A1 ata4 Which would produce output like this:

[3:0:0:0] cd/dvd Optiarc DVD RW AD-7280S 1.01 /dev/sr0 dir: /sys/bus/scsi/devices/3:0:0:0 [/sys/devices/pci0000:00/0000:00:1f.2/ata4/host3/target3:0:0/3:0:0:0] 

Which would indicate that the device (Optiarc DVD RW AD-7280S on ata4) wasn't ready when called upon.

This should be enough information to allow you to locate the troubled device.

sudo lshw -c storage -c disk gives you a lot of info regarding your hard-drives. Eg:

 *-scsi:1 physical id: 2 logical name: scsi2 capabilities: emulated *-disk description: ATA Disk product: ST31000524AS vendor: Seagate physical id: 0.0.0 bus info: scsi@2:0.0.0 logical name: /dev/sdb version: JC4B serial: 5VPDESM5 size: 931GiB (1TB) capabilities: gpt-1.00 partitioned partitioned:gpt configuration: ansiversion=5 guid=d6e747d2-3e9c-47c2-865b-44f8d7cc5808 sectorsize=512 *-volume description: EXT4 volume vendor: Linux physical id: 1 bus info: scsi@2:0.0.0,1 logical name: /dev/sdb1 logical name: /mnt/hdd0 version: 1.0 serial: 2de34713-f0ee-4a12-9214-21a5431a7b7b size: 931GiB capabilities: journaled extended_attributes large_files huge_files dir_nlink recover extents ext4 ext2 initialized configuration: created=2013-07-20 14:14:09 filesystem=ext4 lastmountpoint=/mnt/hdd0 modified=2013-08-29 21:29:24 mount.fstype=ext4 mount.options=rw,relatime,errors=remount-ro,data=ordered mounted=2013-08-29 21:29:24 state=mounted 

I suspect physical id gives you the physical port the HDD is connected to (2 in this case).

sudo apt-get install lsscsi

tech@tech:~$ lsscsi [2:0:0:0] disk ATA SAMSUNG HD040GJ/ ZG10 /dev/sda [3:0:1:0] disk ATA WDC WD3200AAJS-0 03.0 /dev/sdb [4:0:0:0] disk Generic- Compact Flash 1.00 /dev/sdc [4:0:0:1] disk Generic- SM/xD-Picture 1.00 /dev/sdd [4:0:0:2] disk Generic- SD/MMC 1.00 /dev/sde [4:0:0:3] disk Generic- MS/MS-Pro/HG 1.00 /dev/sdf 

this utility will give you ATA port 0 to 3.

sudo lshw -c storage -c disk gives you a lot of info regarding your hard-drives.

The bus info fields give you the physical port each HDD/SSD is connected to (ports 0 and 2 in this case).
Note that the number may differ if your system has multiple SATA controllers (on-board or via extension cards).

For example:

 *-scsi:0 physical id: 1 logical name: scsi0 capabilities: emulated *-disk description: ATA Disk product: Samsung SSD 840 physical id: 0.0.0 bus info: scsi@0:0.0.0 logical name: /dev/sda version: BB6Q serial: S1DBNSAF791657P size: 232GiB (250GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sectorsize=512 signature=d6cfe005 *-scsi:1 physical id: 2 logical name: scsi2 capabilities: emulated *-disk description: ATA Disk product: CT500MX500SSD1 physical id: 0.0.0 bus info: scsi@2:0.0.0 logical name: /dev/sdb version: 010 serial: 1810E132AC1E size: 465GiB (500GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sectorsize=4096 signature=0007569c 

Probably too late for this question, but 10 years later I had the same need:

I always have an issue to find out quickly which disk is which port on my desktop. So, given I have labeled cables on disk side (they are very difficult to follow from motherboard), I wrote a quick and dirty script, which uses /dev/disk/by-path information :

#!/usr/bin/env bash # # output sata/disk relationship. find /dev/disk/by-path/ -regex '^.*ata-[0-9]+$' -print | while read -r file; do sata=$(echo "$file" | sed -n 's|.*\(ata\)-\([0-9]*\).*|s\1\2|p') drive=$(readlink -f "$file") printf "%s %s \n" "$sata" "${drive##*/}" done | sort exit 0 

Output example:

$ sata2disk.sh sata1 sda sata2 sdb
