find out if disk is IDE or SATA
Interesting question. dmesg
should have something like this if it's a SATA drive:
dmesg | grep -i SATA
[ 3.972803] ata3: SATA max UDMA/133 cmd 0xe800 ctl 0xe400 bmdma 0xd800 irq 18
[ 3.972807] ata4: SATA max UDMA/133 cmd 0xe000 ctl 0xdc00 bmdma 0xd808 irq 18
I then grep'ed the dmesg
output for "ata3" and found the serial number:
dmesg | grep -in ata3
397:[ 3.972803] ata3: SATA max UDMA/133 cmd 0xe800 ctl 0xe400 bmdma 0xd800 irq 18
409:[ 4.183701] ata3.00: ATA-7: ST3160812AS, 3.ADH, max UDMA/133
410:[ 4.183706] ata3.00: 312500000 sectors, multi 16: LBA48 NCQ (depth 0/32)
411:[ 4.267004] ata3.00: configured for UDMA/133
which could then be looked up smartctl
or hdparm -i /dev/<your disk(s)>
to match serial with device.
I'm sure someone with l33t shell scripting skillz could do this all up on one line, but this should be pretty solid. If any doubts, I'd check the serial number against the manufacturer's Website as Madhatter suggested.
I ran the same dmesg | grep -i SATA
on Ubuntu running on a VMware virtual machine (which treats the virtual drives as SCSI) and a server with SCSI disks; both returned nothing.
One pretty reliable method is to use lshw to lookup the model number and then to lookup the model number on Google to see what type of device it is. This method doesn't work if the drive is in a USB enclosure, some USB controllers hide the HD info from you.
So for this system you would do a search on ST31500341AS. and find that it is a 1.5TB SATA drive.
root@pabil:# lshw -class disk
*-disk:0
description: ATA Disk
product: ST31500341AS
vendor: Seagate
physical id: 0
bus info: scsi@0:0.0.0
logical name: /dev/sda

If it were IDE, it would very likely show up as /dev/hda. You could try
smartctl -a /dev/sda
which will produce a lot of information including manufacturer and model number; cross-referencing that on the manufacturer's website is usually fairly simple.
