Unable to mount external HD in 10.04

[mathfreak123]

The title says it all. I have a SimpleTech Signature Mini 500 GB USB external hard drive that just won't mount ever since I upgraded to 10.04.

I have no clue what to do, and I don't think autofs is what 9.10 used before. :S

(In all seriousness, I kind of want to downgrade back to 9.10. This probably won't be easy, so the best way to do this is a clean install, right?)

[mikewhatever]

I think it's silly to reinstall just because a usb device wouldn't mount. At least try troubleshooting first. Does an entry appear in the left panel of the file browser? Do you get any errors? Plug the drive in, then run the following commands and post the outputs:


sudo fdisk -l
dmesg | tail

i have the same problem after 10.04 update. ALL USB and drives not recognised. Total beginner . take it easy . I have posted the terminal info .here .help.BeSorry, try again.

What do you mean by 'not recognized'? Do you get 'NOT RECOGNIZED' icons on the desktop for every usb drive?
As you can see, there is a 1GB (/dev/sdb) usb flash drive which is definitely recognized. Are there more attached?

[mathfreak123]

It's not just that I want to reinstall due to a hard drive not being recognized, but there seem to be more issues for me to deal with in 10.04. Oh well... gotta fix them one-by-one...

i am having this problem aswell..

my exHD is recognised and mounts fine, but my Fujifilm camera does not mount and is not recognised in the nautilus

[mathfreak123]

I am currently using autofs and automount as temporary fixes to this problem. If anyone has a better solution, please post it on this thread to share.

[mikewhatever]

As you can see from the output, you have a 500GB ntfs hdd, /dev/sdb, which is recognized just fine. The problem seems to be that it doesn't show in Nautilus, nor does it automount. In case you dual boot with Windows, try running a file system check on that drive.

Edit:Also, make sure to always unplug the drive properly. If you just pull the cord, the ntfs partition gets marked as 'unclean' and wouldn't automount in Ubuntu.

[egalvan]

running a file system check on that drive[/B].

+1

He shows a bootable NTFS, so it's probably dual-booting with Windows.

He should boot into Windows, do a complete "check disk for errors",
re-boot into Windows and check it again (Windows will sometimes miss errors, this step will help)
then shut down and boot into Ubuntu.

then run


mount

to show all mounted drives.

[23dornot23d]

I just want to add a quick one liner here ....

Sometime the USB drives can be slow at picking up on initial boot ...... I sometimes have to re-start the machine twice from a cold start ...... for it to mount my USB drives ...

I have a Terra Drive and a 500gig plugged in most of the time but as I say from the first boot up in a morning ..... sometimes I have to re-start the computer after the drives have been powered up properly ......

Just a thought ..... hope this helps .....

( If you do not boot up from your USB drive .....
see if it mounts - by plugging it in once you get the desktop loaded ... )

[sb5551]

I don't know if this helps, but I am having the same kind of problem with my external harddrive; however, it is a network hardrive. I can get it mounted by using connect to server just like I did in 9.10, but nautilus can't show the folders. It just says error in the steam or something. Sorry I don't have the computer near me right now.

I can get into the drive through my computer when booting into windows 7 and see all the folders. I can also get see all the folders through my gf's mac. I can also see the folders going through the internet of mounting it on my netbook using 9.04. It is just 10.04 that it doesn't work.

I think the problem you describe is quite a bit different. See, we've been discussing usb drives that are directly attached to the computer usb port. Yours seems to be a samba related issue, but since you can access the drive through 'Connect to server...', I don't see the problem.

[sb5551]

Sorry, I thought it was the same because his computer was recognizing the drive, but he couldn't see the folders, just like I can't see my folders but nevermind. I will start my own thread, don't mean to hijack this one.

[mathfreak123]

Went into windows and checked the disk. I booted back into Ubuntu, and the same result occurs: still can't mount. It says I'm not authorized to mount the drive. I can mount fine with sudo, but then everything is labeled as owned by root, which can be pretty annoying, since nearly doing anything with the files would require me to use sudo.

Using sudo chown is a second option, but that's just as annoying. I am still currently using autofs to mount my disk.

[mikewhatever]

mathfreak123, How exactly were you trying to mount it, when the authorization error appeared?

[mathfreak123]

I just plug it in and wait for it to mount like in 9.10. Instead of mounting, I get the "unable to mount" message.

To get around that, I usually either use sudo mount (which makes all the files on the drive appear to be owned by root), or I let autofs take care of it for me. :S

EDIT: I'm still considering reinstalling Karmic, and it's not just because I'm having issues with mounting external HDs. I seem to be having some other problems as well.

EDIT: I'm still considering reinstalling Karmic, and it's not just because I'm having issues with mounting external HDs. I seem to be having some other problems as well.

To be honest, I still haven't switched to Lucid, as despite the bashing, and some initial sound problems, Karmic has been working very well for me. Ubuntu is known to be a little 'rough around the edges' at the release date.

[mathfreak123]

Reinstalled Karmic. I was beginning to have issues just logging in on Lucid (in addition to other things). I think it'll be best for me to stick with Karmic for a while. I'm sorry for inconveniencing everyone who has tried to help.
