external usb hdd

jomen · 08-25-2008, 06:27 AM

It maybe the cable - or that the drive is drawing too much power and the port alone can't supply it reliably.
Do you supply external power or just connect it to the port with one cable?

Another hint with no solution to it:

Code:

usb 2-1: new high speed USB device using ehci_hcd and address 25
usb 2-1: device not accepting address 25, error -110
hub 2-0:1.0: unable to enumerate USB device on port 1

I have seen this kind of failure with an older USB-stick I had.
I could use this device on my laptop without problem. But when I plugged it into a wireless home router that had an external usb-port
- it would not work and would show these errors when I plugged it in. Some kind of hardware incompatibility between the USB-sticks controller and the one in the router...
I never made it work - but another one worked just fine.
For this USB-stick supplying external power was not an option of course.

The drive has its own power supply, but the problem is not the power supply or the cable. My external hdd works fine with any pc I connect it.
jschiwal I tried to use ntfsfix but the first thing this utility does is to mount the device.And this is where I have prob.
Thnx for everything guys if I find a solution I will post it here. If not... I'll try fedora :P

Is it safe to do this? If you are using ntfs-3g, is there much risk of data corruption? I have a garden of dual-booting linux/Windows systems growing in my house, and several ntfs formatted usb external HDD which have been used up-to-now to backup my Windows machines.

I'd like to be able to write to these drives directly via USB from my Linux distros (fedora, Debian, Ubuntu) rather than as hosted over a network with samba which I'm still learning about.

I'm also interested in choosing good file systems to invest my data in for long term security and preservation... In the Windows world, I was banking on NTFS, I guess in the Linux world it is ext3.

Thanks.

I would prefer using ntfs-3g over the captive ntfs kernel module for write support. One thing you won't be able to do is fully repair a bad filesystem. The ntfsprogs package supplies an ntfsfix program. It will fix the most common problems and then mark the filesystem as dirty so that windows will scan the drive when you reboot into windows.

If the drive is connected to a windows machine and you share it, you don't need to configure anything in your smb.conf file. The smb.conf file is for the server. When you access a windows share, you will be using a client.

I find using konqueror is the most handy program for access smb shares. You can split the window and on one side enter the uri "smb://"

You can also mount a share.

Code:

mount -t cifs //hostname/sharename /mount/point -o rw,uid=yourusername,gid=yourgroup,fmask=117,dmask=007,username=windowusername,password=windowspassword

You can also add an entry to /etc/fstab. If you do, use the "credentials" option instead of username and password. Use the noauto option to prevent the system from hanging if the windows host isn't up, when booting up. I would also use the _netdev option. If you also add the "user" option, you can mount it without su'ing to root.

Please see the manpages for mount, fstab and smb.conf. I don't remember the exact name of the program that mount uses to mount cifs shares. cifs.mount or cifsmount or mount.cifs. Anyway, it will have its own man page as well.

I think I posted in the wrong window. Sorry.

Did you format it using Windows or Linux? You have no problems reading/writing using Windows with the drive? This seems very odd. What happens when using a livecd to read the drive? If a livecd will read it, and you can save your data from it, then maybe you can reformat the drive. Just some thoughts!

I had the same problem got so frustrated in the end I tried mandriva with the same results.
Next tried Kubuntu hey presto everything perfect so after 3 years of using suse i am now sticking with kubuntu.

I have had no problem sharing ntfs formatted external drives between Windows and Linux. Something's definitely odd here if the drive is reliably recognized by Windows and cleanly shutdown and removed but refuses to mount with ntfs-3g. Can't add much to the suggestions already made, different usb port, live CD, remounting unders Windows and dismounting cleanly...

Everything I tried didn't work. The only thing left to think was a general rpoblem with the usb ports(since my usb stick wasn't working too).
I made a search on the web and look what I found here....

I don't know if this is your problem but, from the kernel 2.6.25, USB support has been totally rewritten; as a result, a lot of USB devices have had problems with HAL.
