Mount of external ntfs usbdisk fail on boot

Asked by Giovanni Bortolozzo

Hi guys,
I'm new to Ubuntu (but I use Debian sid since 8 years).
Anyway I just install the karmic alpha, since with the last stable version my nVidia ethernet card is not recognized and then I can't use it.

Anyway, I have an extern usb disk formatted with ntfs. On boot it seem to be mounted but as soon as I try to access it I get an I/O error.

With dmesg I can see this messages

[ 62.916010] usb 1-1: reset high speed USB device using ehci_hcd and address 2
[ 70.916009] usb 1-1: reset high speed USB device using ehci_hcd and address 2
[ 71.079392] sd 2:0:0:0: [sdc] Unhandled sense code
[ 71.079395] sd 2:0:0:0: [sdc] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[ 71.079398] sd 2:0:0:0: [sdc] Sense Key : Medium Error [current]

[ 71.079458] Buffer I/O error on device sdc1, logical block 786433

The really strange think is that if I login as root umount the disk and then mount it again (using mount -a or mount /usb-disk1) it works perfectly (it looks like the disk is mounted too early).

On fstab I have this line

UUID="A25C76EB5C76B99D" /usb-disk1 ntfs-3g rw,user,auto,noexec,umask=000 0 5

The system is upgraded to the last avaiable packages.

The kernel version is
Linux nemo 2.6.31-4-generic #22-Ubuntu SMP Fri Jul 24 18:06:15 UTC 2009 i686 GNU/Linux

Any idea?

Thanks in advance
Giovanni

Dear Benny, you are suppose to give constructive answer... if you enjoy on flaming, you lost your time with me.

Anyway I'm old enough to read a message to its end, don't you?

I said, that I get this problem only just after the boot. If I umount this device and *immediately* i remount it IT WORKS!

The device don't have any hardware problem: it works perfectly under Debian/sid, it was double checked with chkdsk /f under windows xp, and it works also in ubuntu if I mount it after that the boot process is finish.

So if you do really have an idea, please let me know, anyway keep your stupid flame for someone else.

Thanks

May be Giovanni you should consider you are running an alpha -version of an OS and report a bug here if you think it is a bug.
You know, I'm almost sure, Ubuntu is a branch of Debian and you work with Debian 8 years.

I know this, I have to choose this alpha since the 9.04 don't work for me (the ethernet card is not correctly initialized).

I'd like to use Ubuntu, since it is released more frequently than Debian (since 4 years I had to use sid to get fresh packages and don't wait an year to get an update gnome desktop).

I can live with some minor bugs of this alpha (i found other less annoying bugs)...

Then what about changing or adding a new ethernet card in your machine and working with 9.04? They are not so expensive I think?

Because the problem is not on the network card (with a vanilla linux kernel it works)... it is just a problem of the kernel distribuited with 9.04...

Benny, maybe my English is not perfect as your, and i'm not able to distinguish all the shade of your meaning, but just to clarify I use linux since 1994/1995. I start with SLS, then Slackware installed on my 486 using about 30 floppies) and then I move to Debian since hamm was released.

So my experience with Linux is solid, both as developer, administrator and simple user. What about yours?
Your question (and answer) seem not so cleaver. So please, before answer as you made, please count to 100 and then play to minesweeper.

There is no hardware flakes. It is just something wrong on the detecting of the disk at the boot time, and this depend on Ubuntu, since with Debian the disk has no problem.

Regards
Giovanni
