If this is not enough, you may have to resort to a diagnostic tool, like smartctl.Or $ sudo fdisk -l 2. Notice that this does not scan your system, but simply reports what the BIOS says your pc is like. Or you can use dmidecode (not available on more recent versions of Linux) which allows you access to your hardware as seen in the BIOS (or, more exactly, in the SMBIOS, System Management BIOS). Or you can query general information about the disk by means of lshw -C disk ( sudo is important, if you omit it you will only display the user journal, not the kernel's). Unless of course you are on systemd, in which case the above command still works, but you can display the kernel messages as follows: sudo journalctl | grep sda dmesg displays the messages stored in /var/log/dmesg. If instead you want messages, including error messages, produced in the current session, then dmesg | grep sda If you want to take a look at your MBR ( if you have one), then dd if=/dev/sda of=mbr.bin bs=512 count=1 If you want the partition table, parted /dev/sdaĪnd the p (for print) will show you the partition table. The proper way is to use udevadm info -a -n /dev/sda It depends on the kind of information you are searching for. My syslog says there is something wrong with my ata2, however, because Linux/Ubuntu swap disk orders all the times, I want to know exactly which of my 3 drives is ata2.

The FreeBSD Find Out All Installed Hard Disk Information says to check the /var/run/dmesg.boot file. I know normally the Hard Disk Information can be get from dmesg, on fresh reboot, but my system has only been up for 15 days, and I've already lost that info. What's the reliable way to find out Hard Disk Information under Ubuntu, after having been booted for several days? $ uptimeĢ1:18:59 up 15 days, 10:46, 11 users, load average: 1.01, 0.82, 0.65
