I have Ubuntu 12.10 installed in Sony VIAO E Series VPCEH16EN, 4GB RAM, 320 GB HDD, Intel Core i3-2310M Processor 2.10GHz. It is a dual boot with Windows7 alongside with it.

I see the system is very slow in responding, any video gets stuck in between the play. Can you please help me find where the bottleneck is. Here is the output of hdparm and smartctl:

------------- HDPARM -------------------
anil@anil-ubuntu:~$ sudo hdparm -Tt /dev/sda6 
/dev/sda6:
 Timing cached reads:     2 MB in  3.51 seconds = 584.17 kB/sec
 Timing buffered disk reads: 160 MB in  3.02 seconds =  52.91 MB/sec
anil@anil-ubuntu:~$

-------------- SMARTCTL -----------------
anil@anil-ubuntu:~$ sudo smartctl -a /dev/sda6

Am I the only one that thinks 584.17 kB/sec for cached reads is so slow! –  Bruno Pereira Feb 28 '13 at 20:26

1 Answer 1

Your S.M.A.R.T. data from your disk shows that your hard drive is failing. I would backup any information you might have important in your disk and replace it asap.

All the Type: Pre-fail warnings should be clear of that with addition to the 104, 105, 106, 107 and 108 errors in the smartctl report.

You can also check the status of your hard disk conditions (show by the S.M.A.R.T. data) by using the palimpsest (Disk Utility) and checking the status there
