[Bug 510443] Re: external usb hard drive unmounts and remounts automatically
flint, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command in the development release from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux replace-with-bug-number Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Tags added: karmic needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/510443 Title: external usb hard drive unmounts and remounts automatically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/510443/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 510443] Re: external usb hard drive unmounts and remounts automatically
Hi, I think I've solved this issue, at least for me. It's rather silly, and don't fully understand how it works, but actually it does, which is all that matters. I remembered I recently started switching the hard drive off at night, so as to try speeding up booting the following morning, i.e. without the system having to detect external devices in the process, and then to switch it on after login. I wondered if that might be the reason of this issue, and tried not to switch it off anymore. Well, the issue has gone for over a month, and that's remarkable, considering the drive used to unmount on a daily basis. I don't know if it is going to help anybody, for in my case it seems it was hardware-related, but anyway I wanted to share. -- external usb hard drive unmounts and remounts automatically https://bugs.launchpad.net/bugs/510443 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 510443] Re: external usb hard drive unmounts and remounts automatically
I have further tested this issue with no luck, but can exclude the drive is faulty. I can use it satisfactorily for any other purpose (watching films, listening to music, transferring data, etc.) and it never unmounts, not even when not downloading or downloading from aMule only. This is what I attempted so far: - It has an EXT4 file system, checked the disc for bad sectors, but the remapping did not solve the issue. - I removed from Transmission all shared torrents, so that users would download only from the files I was also downloading, thus avoiding to heavily uploads to numerous users connected to me. - I've searched the forums, but it's a mess, and no precisely identifiable pattern is to be found: some say it's a HD failure, some the electrical charge to the USB port, etc. I changed USB port, swapping it with the 2nd external HD, but still it's the one used by Transmission to unmount, so it's not the USB port. - I swapped the USB cables of the two hard-drives: if it was the cable, the HD should have stopped unmounting by itself. But it didn't. Also, one thing I noticed is that when I use the auto-remounted drive, new files and folders are not found unless I hit refresh. And those freshly deleted still are displayed, and if I try to access them then I am presented with an error. ** Changed in: linux (Ubuntu) Status: New = Confirmed -- external usb hard drive unmounts and remounts automatically https://bugs.launchpad.net/bugs/510443 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 510443] Re: external usb hard drive unmounts and remounts automatically
Yeah, this is exactly what happens to me, too. Also, I sometimes use aMule along with Transmission. When the drive unmounts, all active files from both applications give an error message, and can't be reactivated unless the programmes are restarted. When they're restarted, each file must be reactivated manually, for they're all paused or stopped - Transmission will verify all local data for those files. In the end, though, I'm not sure what causes the issue, neither if the P2P apps are the culprits here. -- external usb hard drive unmounts and remounts automatically https://bugs.launchpad.net/bugs/510443 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
