"hdparm" as the article said to do, I got something saying command not recognised. | | | | | Joined: Oct 2002 Posts: 37 Junior Member | | Junior Member Joined: Oct 2002 Posts: 37 | hdparm, as I'm fairly sure you are aware after reading the article, is a utility that allows you to configure your hard drive for maximum performance. Chances are you still have it on your computer. Do a locate hdparm. That should give you the path name to it. Then, to run it. Just type the full path name. Probably something like /usr/sbin/hdparm. Then give it the options it loves and needs. The first option is probably the hard drive. So, /path/to/hdparm hda I'd imagine.
Unless you are running a SCSI hdd. Then it'd be sda. Whether the article works anymore, I believe it would. I can't see any real reason why it wouldn't / shouldn't. It should be fairly easy to tell for sure though by just looking at the parameters of your hard drive using the hdparm command. Oh yeah. You'll need to be running as root to do all these as well.
Hope that helps some. | | | | | Joined: Mar 2002 Posts: 562 UGN Supporter | | UGN Supporter Joined: Mar 2002 Posts: 562 | Originally posted by ReverendNinjaSox:

Hope that helps some. Yes it dose a bit. you said do a locate hdpram... YOu mean $locate hdparm Running as root isn't a problem.

There are a lot of tweaks out there, just remember you gotta becareful what you do (don't [censored] up your system).

You can also issue a find command. However, more then likely you are using an up to date Linux distro with the locate utility. It automatically builds a database of all the files on your system once per day I believe. I can't remember off the top of my head and I'm a little sick so don't really feel like looking it up. So just type locate hdparm at the command line. If that doesn't work. Do a find for hdparm. That should point you to the right location for it. Hope that helps.

Locate returned 5 results.... I am at work now so I do not have them with me, but none of the results helped me. I will try find when I get home. | | | | | Joined: Oct 2002 Posts: 21 Junior Member | | Junior Member Joined: Oct 2002 Posts: 21 | You can also do a:
# which hdparm
This will only search your path for the program so it may give you less files to choose from. In my distro it is in /sbin
By the way. Most shells do not provide all the sbin directories in the "normal" user's account. So I usually add them. For bash I add to the ~/.profile:
PATH=$PATH:/sbin:/usr/sbin:/usr/local/sbin | | | | | Joined: Mar 1983 Posts: 55 UGN Elder | | UGN Elder Joined: Mar 1983 Posts: 55 | Mine is in the /sbin/hdparm as well, just type it as su and it should give you bunch of options. I just logged in as su and typed which hdparm and it spit fowarth information.

Still slower after I made all changes...
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Luckily these changes aren't permanet if I read right. I didn't edit my etc/rc.local script, so they will not take place on every boot up. I am curious though why this didn't work. It should have spead me up, but instead did the opposite. any ideas? | | | | | Joined: Mar 2002 Posts: 562 UGN Supporter | | UGN Supporter Joined: Mar 2002 Posts: 562 | got it. The tut covered a lower mode than my box supports for UDMA modes I modified to hdparm -d1 -X udma5 /dev/hda Now look at my times /dev/hda:
