HDD performance is slow in ubuntu

rated 0 times [ 7] [ 0] / answers: 1 / hits: 30551 / 2 Years ago, mon, march 28, 2022, 4:07:35

I am running ubuntu 12.04(32 bit). Suddenly after a reboot my laptop did not detect HDD. After couple of restart it failed to detect HDD. Then i change sata mode to IDE from AHCI in BIOS. Then it detect HDD again. And now HDD performance is very slow. I run a short test in disk utility. It shows no error or warning.

hdparm -i /dev/sda

hdparm -tT /dev/sda

/dev/sda:

 Timing cached reads:     2 MB in  2.70 seconds = 759.55 kB/sec

 Timing buffered disk reads: 172 MB in  3.02 seconds =  56.99 MB/sec

These are the result of hdparm command. Does it normal? please help.

EDITED

I found something. After some ideal time SDA link goes down (speed 700 kb/sec). It's back after a minitue (speed in MB/sec).

Thanks for posting the Output,

The above results suggest that they have already crossed their Threshold values, it would be wise to take backup , and Replace it if is under Warranty period. Further pressing to get the desired performance may damage it.

Reallocated Sectors Count showing 736 , While primarily used as a metric of the life expectancy of the drive, this number also affects performance. As the count of reallocated sectors increases, the read/write speed tends to become worse because the drive head is forced to seek to the reserved area whenever a remap is accessed.

Spin Retry Count showing 202 It is the count of retry of spin start attempts. This attribute stores a total count of the spin start attempts to reach the fully operational speed (under the condition that the first attempt was unsuccessful). An increase of this attribute value is a sign of problems in the hard disk mechanical subsystem.

For further reading refer here and S.M.A.R.T. wiki

P.S: A low health value alone does not neccessary mean that the hard disk will surely die in the near future (to verify this, a complete (hardware) examination is required), but there is a real chance for failure.
