Cannot mount USB Hard Drive

CartersAdvocate · 06-19-2007, 05:28 PM

I'm a little rusty on my Linux so I'm sure this is something simple and stupid that I'm missing, but I can't get my USB hard drive to mount in slackware. I just compiled the 2.6.21.5 kernel (although it didn't work on the 2.4.33.3 from the installation either) and I have the usbcore, usb-storage, and ehci-hcd modules loaded, but when I plug in my usb hard drive, it gets power, but I can't mount it. I'm using an SATA hard drive, so my sda device is that, so I don't know what device it would be either, but nothing shows up in dmesg or lsusb when I connect it.

Thanks in advance for any help.

Just a thought, have you tried booting with the drive pluged in. The kernel may reconize it if it's plug in during boot. May be worth a try. If it does then you can write a udev rule to take care of it so the SYSFS will know what it is when the kernel see's it.

No, it still doesn't work when I have it plugged in when I boot. I looked through the entire dmesg after I booted up, and noticed this:

ehci_hcd 0000:00:02.1: Found HC with no IRQ. Check BIOS/PCI 0000:00:02.1 setup!
ehci_hcd 0000:00:02.1: init 0000:00:02.1 fail, -19

Also, I keep seeing this in dmesg which I think may correlate to when I plug the hard drive in:

atkbd.c: Unknown key released (translated set 2, code 0x81 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e001 <keycode>' to make it known.

Let me know if either of those mean anything to you.

Could you tell us a little about the usb drive itself? Manufacturer, how old (1.1 or 2.0)? Thank you.

Hern_28 · 06-20-2007, 09:00 AM

ls -l /dev/usb

ls -lR /dev/disk

udevinfo -a -p /sys/block/sda

and do you have scsi support enabled?

CartersAdvocate · 06-20-2007, 05:53 PM

It's an Iomega 80GB USB 2.0 hard drive. I'm at work and don't have the drive plugged in, so I can't give the results of those commands yet. Yes SCSI is enabled, though, I know that.

quietguy47 · 06-20-2007, 08:07 PM

Have you added it to /etc/fstab and /mnt?

What would I add to fstab? It's not /dev/sda1 because that's my internal SATA hard drive

the way I do it is:

1. plug in the device
2. dmesg | tail
3. vi /etc/fstab
/dev/sdb1 /media/usb0 auto noauto,owner,users,rw 0 0

4. mkdir /media/usb0
5. mount /media/usb0

proc             /proc            proc        defaults         0   0

now for your situation, the device should be sdb1, unless you have two SATA drives already connected, in either case the dmesg | tail should show you where its getting put in /dev

btw - there is a more elegant way to handle this stuff with udev rules (or so I've heard)

CartersAdvocate · 06-20-2007, 10:55 PM

Nothing shows up in dmesg when I plug it in...which is the problem. I'll have to check my mobo connection and my BIOS when I get home tomorrow. There's something not talking right between my USB port and my kernel I think.

agentc0re · 06-21-2007, 07:59 AM

is the USB harddrive found on another machine? do you have a USB Mouse? if you do plug your mouse into the other use ports to see if they are working. that'll save you the trouble of taking your box apart unless they really aren't plugged in there well.

My USB hard drive has worked fine on all my Windoze boxes...I'll try the USB mouse.

Some USB or SCSI modules may not be loaded or compiled into the kernel.
Post the output of the command lsmod.

udevinfo -a -p /sys/block/sda just gives me information on my SATA hard drive...using /sys/block/sdb returns nothing.

Also, I tried plugging in a USB mouse and it also doesn't show anything on dmseg. I forgot my new motherboard has the USB ports built into it, so there's no connection to check, so that isn't the problem. I think the problem may be BIOS related. I looked through dmesg again and here's the few lines before the one I posted before:

Code:

PCI: No IRQ known for interrupt pin A of device 0000:05:0b.0.

you probably left out some needed modules. try a knoppix or ubuntu cd to see if it works there then you'll know what you left out.
