I noticed that my Ubuntu is lagging EXTREMELY badly but only the first time I do things after what I did gets loaded into RAM the lag stops totally. I ran some tests and I guess one of my laptop hard drives is borked.

Im assuming that I have to replace the drive, is there some command I can issue to see the exact specs on the drive so I can then buy it online?

I don't want to have to open up the laptop, find the specs. Then open it again when the new drive arrives.

Or is there another cool hacky command or way to partition my drive to avoid using the bad spots? A while ago when my drive failed I mounted it useing an alternative superblock and this worked and still does i guess.. – Banned_User May 15 '14 at 13:42
I found the hacky solution I wanted. I ran the command "badblocks /dev/sda1" and then noticed they were all near the front of the drive. So I created an unallocated partition at the front of the drive consisting of 50% of the total size. I then tested the second half of the drive! AND WALAAAAAAAA!!!!!! IT WORKED!!!!! Im going to buy a new drive anyway but this process taught me alot :) – Banned_User May 15 '14 at 17:01

smartctl command from smartmontools package is what you want for that

% sudo smartctl -i /dev/sda

Thanks I hope this helps someone but the first answer was PERFECT so im not even bothering with this, do you know if I can somehow use only part of my hard drive? The hole thing still works but super slow. I know nothing of hardware but maybe there is a way to say only use the good part of the hard drive? Maybe when hard drives go bad only certain portions go bad? – Banned_User May 15 '14 at 14:06
Try to test it for bad boot sectors and repair them . – nux May 15 '14 at 14:41
ok i will try to help you mate . – nux May 15 '14 at 14:47
You already did! I ran the command "badblocks" to find bad boot sectors and it saved 50% of my drive!!! its working super fast :)! THANKS!!! – Banned_User May 15 '14 at 17:03
you are welcome my friend :) happy to hear that – nux May 15 '14 at 17:34

$ lsblk

The command lsblk by default will list all block devices in a tree-like format. Type lsblk --help to see more options
