Disque IDE reconnu comme sata?

Bonsoir,

J'ai un portable Dell Inspiron 6000 équipé d'un disque en IDE (Samsung MP0804H 80Go).

En cherchant sur ce forum des threads concernant l'UDMA, j'ai pu constater que normalement, les durs IDE sont labellisés hdX et les sata sdX. Or mon disque est reconnu comme sda...

J'ai fait un 'hdparm -tT /dev/sda' qui me donne:

Timing cached reads:   2736 MB in  2.00 seconds = 1368.39 MB/sec
Timing buffered disk reads:   88 MB in  3.05 seconds =  28.81 MB/sec

Comme vous pouvez le voir, les vitesses semblent normales.

En fait, je n'ai pas de problème, mais j'aimerai tout simplement comprendre

Merci d'éclairer ma lanterne!

Désolé de pas avoir pu répondre plus tôt

que donne un

cat /etc/hdparm.conf

Voici le résultat de la commande.

## This is the default configuration for hdparm for Debian.  It is a 
## rather simple script, so please follow the following guidelines :)
## Any line that begins with a comment is ignored - add as many as you 
## like.  Note that an in-line comment is not supported.  If a line 
## consists of whitespace only (tabs, spaces, carriage return), it will be
## ignored, so you can space control fields as you like.  ANYTHING ELSE
## IS PARSED!!  This means that lines with stray characters or lines that 
## use non # comment characters will be interpreted by the initscript.  
## This has probably minor, but potentially serious, side effects for your 
## hard drives, so please follow the guidelines.  Patches to improve 
## flexibilty welcome.  Please read /usr/share/doc/hdparm/README.Debian for 
## notes about known issues, especially if you have an MD array.
##
## Note that if the init script causes boot problems, you can pass 'nohdparm' 
## on the kernel command line, and the script will not be run.
##
## Uncommenting the options below will cause them to be added to the DEFAULT
## string which is prepended to options listed in the blocks below.
##
## If an option is listed twice, the second instance replaces the first.
##
## /sbin/hdparm is not run unless a block of the form:
##      DEV {
##         option
##         option
##         ...
##      }
## exists.  This blocks will cause /sbin/hdparm OPTIONS DEV to be run.
## Where OPTIONS is the concatenation of all options previously defined
## outside of a block and all options defined with in the block.

## New note - you can use straight hdparm commands in this config file 
## as well - the set up is ugly, but it keeps backwards compatibility
## Additionally, it should be noted that any blocks that begin with 
## the keyword 'command_line' are not run until after the root filesystem
## is mounted.  This is done to avoid running blocks twice.  If you need 
## to run hdparm to set parameters for your root disk, please use the 
## standard format.

#Samples follow:
#First three are good for devfs systems, fourth one for systems that do 
#not use devfs.  The fifth example uses straight hdparm command line
#syntax.  Any of the blocks that use command line syntax must begin with
#the keyword 'command_line', and no attempt is made to validate syntax.  
#It is provided for those more comfortable with hdparm syntax.

decrit un peu ta config

Noyau ...

Le noyau est le 2.6.17-11-generic.

Voilà. Je le répète, je n'ai aucun souci particulier. Simplement envie de comprendre
Merci à vous deux d'avoir répondu
