How to locate devices using File Browser


I am trying to find devices in /dev. but clearly don't understand something.

Using the Device Manager, I find the hard drive listed and looking at the advanced tab:
under Key, it shows block.device and under Value, it shows /dev/hda.

But when I go to /dev using the File Browser, hda shows up with a red X in front of it and properties shows:

Type: x-special/device-block
Size: 0 Bytes
Location: /dev
MIME type: -special/device-block

Why the apparent inconsistency and how can I see the hard drive in the file browser?

The files in /dev/ are special device files.

Compare
file /dev/hda
with
file -s /dev/hda

Thank you for this, but I don't understand. I am trying to learn how to physically locate the various devices, such as hard drive, cdrom/rw, dvdrom/rw, usb, etc so that when I try to install a new device, I can find it, then mount it.

I started with a device that I knew was working and that shows up in the Device Manager, then tried to find it. So is the hda in /dev the hard disk or does it refer to something else? Why the red X?

I installed a DVD-RW but it doesn't show in device manager and I don't seem to be able to find it in order to mount it.

Can anyone assist me with this?

Try this

Quote:
dmesg | grep CD


Type it in the console, The output should tell you what dev/ item is what dvd/cd drive

Mine for example is

Quote:
desktop:~$ dmesg | grep CD
[17179575.508000] hdc: IDE DVD-ROM 16X, ATAPI CD/DVD-ROM drive
[17179576.292000] hdd: SONY DVD RW DW-Q30A, ATAPI CD/DVD-ROM drive
[17179576.524000] Uniform CD-ROM driver Revision: 3.20
[17179576.532000] hdd: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(66)
So my dvd-rw is hdd

If its not there it's not being recognised when you boot up as far as I can tell.

I know nothing about this - I got it from here

Depending on your distro, you may get mount points set up automatically. If so , they will be in either /mnt or maybe /media

Also, check to see what is actually mounted by doing: cat /etc/mtab

Tell us what distro for better answers...

Apology for the absence, but lots of in-laws and out-laws in town.

dmesg | grep CD yields no output whatsoever, with and without sudo.

The only thing showing in /mnt is a Windoze partition.

/media shows hda and hdc with an arrow slanting downward to the right (link?), ide0, ide1, and drivers. Properties for each shows:

for hda: it is a link, location is /proc/ide, volume is proc, contents: 10 itmes totalling 0 bytes, and link target is /proc/ide/ide0/hda

for hdc: much the same as hda, except to hdc instead of hda in link target and only 6 itmes, totalling 0 bytes

whereas ide0 shows type as a folder with 14 items tot. 0 bytes, location /proc/ide, and

ide1 almost the same except with 10 items

/proc/ide/ide0/hda props show pretty much the same sort of info

???????

Edit: forgot to mention running Ubuntu 6.06. Thanks
