How to check whether a disk supports 32-bit IO


Hi All ,


I want to know enable 32-bit IO-support on my 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 to help in determining the IO speed of the disk .


Thanks
-Bz

Go the the OEM site and read the spec sheet on the drive and maybe the controller it attaches to.

I'd think that ultimate boot cd generic tools for hard drives would tell it but they may not on all mfg's of hard drives.
