Hard drive info linux
In /etc/udev/les such lines can be found: kernel"sd*!0-9sr sysfsieee1394_id envid_BUS"ieee1394 kernel"sd*!0-9sr envid_serial importprogram lib/udev/usb_id -x kernel"sd*!0-9sr envid_serial -g -x -s p -d tempnode".
Since I have removed the drive, the Linux fails on boot because it cannot locate the device.
The links under /dev/disk/by-id is created by udev.The ID_model key could be used to localise more precisely the beginning of the serial number, as (it seems to me) its first 15 characters are added to the ID_serial (spaces replaced by).Kernel"sd*!0-9sr envid_serial -g -x -a -s p -d tempnode".But there is at least one direct way: udevinfo -q path -n /dev/sda /block/sda udevinfo -q symlink -p /block/sda a space separated list is returned.Note : Before running e2fsck command, you just make sure the drive is not mounted.Yes, smart exists and things like smartctl can read its results for you, but you shouldn't bet.
Under Linux since the dawn of time, disks and partitions are listed in /proc/partitions.
So the by-id path can be found.
Linux also provides the lsblk utility which displays a nice tree view of the storage volumes (since util-linux.19, not present on embedded devices with BusyBox).
It if can contain then this method is not bullet proof.
Badblocks command will detect all bad blocks(bad sectors) on our hard disk and save them in a text file so that we can use it with e2fsck to configure Operating System(OS) to not store our data on these damaged sectors.
When HD decides to fail, it will do it without a previous warning and Murphy's law says that the failure will happen during the most unwanted moment.
Bad sectors or bad blocks is the space of the disk which cant nessus plugins tar gz be used due to the permanent damage or OS is unable to access.If a HD starts to give you physical hints about an upcoming failure, no software will help.unfortunately it is not trivial to find out this by-id symlink from the name of the device.Also different methods may treat edge cases differently ea sports games fifa 2008 (fake disks of various kinds, raid volumes, ).Does anybody know any limitation about the serial number?# sudo e2fsck -l /tmp/bad-blocks.Or You can directly get the "composite" serial number: udevinfo -q env -p /block/sda, iD_vendorata.Badblocks is the command or utility in linux like operating system which can scan or test our hard disk and external drive for bad sectors.
