Mounting External HDD

As requested, this thread has now been moved to Linux-Hardware

J_K9 · 04-01-2005, 03:00 AM

I looked at finegan's thread about posting in the Hardware forum, and I have tried to follow it:

Here are two parts of my dmesg, which I found relevant to USB:

Code:

usbcore: registered new driver hiddev
usbcore: registered new driver usbhid
drivers/usb/input/hid-core.c: v2.0:USB HID core driver

uhci_hcd 0000:00:07.2: UHCI Host Controller
uhci_hcd 0000:00:07.2: irq 9, io base 00001800
SELinux: initialized (dev usbdevfs, type usbdevfs), uses genfs_contexts
uhci_hcd 0000:00:07.2: new USB bus registered, assigned bus number 1
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected

I also went to the USB compatibility list site, and found the info on my LaCie.

Quote:

...Update: I got some trouble using it with various USB 1.1 host controllers. Maybe not enough power?...
...It works with kernel 2.6.10 and USB 2.0, but still not with USB 1.1.

My laptop uses USB 1.1, and I have realised that my LaCie makes some crackling noises every two seconds for no reason at all when it's plugged into my FC3 lappy, but when plugged into my Mac it doesn't make any noise! Maybe, as W. Dieter said, it could be because of a lack of sufficient power? If so, is there any way to solve this (apart from buying an AC power adapter)?

Thanks,

The drive was probably partitioned with some kind of drive overlay software. Is it one of those one-touch backup things? Maxtor is notorious for doing this. Go to www.maxtor.com and download Max-Blast (or whatever they call it now), boot to a Windows machine and run it. That will tell you if a drive overlay program is controlling that hard drive's partitions. If it is then you'll have to pull off your data, re-partition with conventional means and copy your data back on.

Edit: Nevermind....didn't see the third page

And I also didn't pay enough attention...I was thinking the Maxtor wasn't working. I just needed to read more carefully....sorry about that.

Also...you can grab a PCMCIA USB 2.0 card fairly cheap if it's important to have this drive working on your laptop. Some of the cards are even powered by an external adapter for problems like this.

lol no problems leonardh. Thanks for letting me know about the PCMCIA USB cards, I might have to pick one up tomorrow and see if that works! Anyway, thanks for your help!

Peace out --

J_K9, since your log file suggests usb mass sotrage is recognized in scsi emulation.
#mkdir /mnt/external
#mount /dev/sda1 /mnt/external
#cd /mnt/external
#ls /mnt/external
should give you the drives contents

Have you got other scsi hard drives on your system?
What file system (FAT32/NTFS) is you external dirve formatted with?

If you can't mount as I've said, plzz give the exact error message it shows when you run "mount /dev/sda1 /mnt/external".

J_K9 · 04-02-2005, 04:28 AM

It is a FAT32 drive. I got an error when trying to mount it, here it is:

Quote:

# mount /dev/sda1 /mnt/external
mount: special device /dev/sda1 does not exist

This was after I had creater the dir /mnt/external. I have also tried mounting /dev/sda2 but it returned the same error. Any help would be appreciated, but if worst comes to worst I'll just buy the USB 2.0 adapter on Monday.

Hmm,
#cd /dev/
#ls sd*

and post the output here.

evil_empire · 04-02-2005, 07:35 AM

Ok,update, as soon as you see this post

Shut the computer down.
Reboot the computer but without attaching the external drive!!!
When you are logged on and KDE(or whatever window manager) is up and running,
open a console and than run "dmesg".
now, attach the external drive and then after about 2 secs run "dmesg" again.

Copy the last(ending) 20 lines from the output of the dmesg, and than post it here.

Also post the ouput of "mount" command. I mean just "mount" alone.

J_K9 · 04-12-2005, 03:23 AM

Sorry I took so long, I've been on holiday! I did what you said, and here are the last 20 lines of my dmesg:

Code:

And the result of 'mount':

none on /dev/pts type devpts (rw,gid=5,mode=620)

none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs ( rw)

I hope you can still help. Once again, sorry for the delay!

I think I had the same problem.
After you activated "SCSI disk support" in your kernel, the problem should be fixed.

Edit: Module name is: BLK_DEV_SD

J_K9 · 04-15-2005, 03:26 AM

Hey dulait: how did you activate that?

dulait · 04-15-2005, 04:17 AM

You type in a root shell:

1. cd /usr/src/linux (or specific path: /usr/src/linux-2.x.x)
2. make xconfig (or make menuconfig)

Now your see the kernel configuration:

3. in the menu scsi support (or something similar, I'm not on the pc), you choose scsi disk support (as a module!)
4. quite and save

type again:

5. make modules
6. make modules_install
7. modprobe blk_dev_sd
8. mount /dev/sda1 /mnt/external (or your specific sdXX)

Hope this will help.
