[Solved]
I read some where in another post that I need to change the BIOS Hard disk mode from IDE to AHCI!
Sure enough, I did the change and after saving the BIOS and rebooting, the system rebooted TWICE and then booted my ubuntu lucid OS.
Now I need to do some speed test to see if SATA3 controller and hard disk makes a difference!
Here is the result:
When connecting the HD to the SATA2 port:
$ sudo hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 18796 MB in 2.00 seconds = 9407.90 MB/sec
Timing buffered disk reads: 416 MB in 3.01 seconds = 138.19 MB/sec
When connecting the HD to the SATA3 port:
$ sudo hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 18744 MB in 2.00 seconds = 9381.51 MB/sec
Timing buffered disk reads: 416 MB in 3.01 seconds = 138.27 MB/sec
Hmm, Interesting!! there is no difference!!!
Does anybody know why?
