Hi All ,
I want to know enable 32-bit IO-support on my SATA hard drive
using hdparm . But before I enable 32-bit support , I want to know
whether my hard drive supports 32-bit IO or not.
I tried the -I option with hdparm , but it is not telling clearly
whether it supports 32-bit or not.
The following is the output from the hard drive of my system (hdparm -I ) .
=====
Commands/features:
Enabled Supported:
* NOP cmd
* READ BUFFER cmd
* WRITE BUFFER cmd
* Host Protected Area feature set
* Look-ahead
* Write cache
* Power Management feature set
Security Mode feature set
* SMART feature set
* FLUSH CACHE EXT command
* Mandatory FLUSH CACHE command
* Device Configuration Overlay feature set
* 48-bit Address feature set
(is it telling that the disk supports 48-bit IO)
Automatic Acoustic Management feature set
SET MAX security extension
* DOWNLOAD MICROCODE cmd
* General Purpose Logging feature set
* SMART self-test
* SMART error logging
=====
Tried smartctl with the -a option also , but no luck .
Any help will be highly appreciated in determining the IO speed of
the disk .
Thanks
-Bz
