Re: [Bug 539064] Re: "Safely remove drive" is waking-up my external HD
Is there any way that the drive can signal the OS about a spindown going to happen? that way, the OS can flush changes *prior* the spindown and the problem of "waking up" will be fixed.

[Bug 539064] Re: "Safely remove drive" is waking-up my external HD
i agree, that this is a design problem of the filesystem/blockdevice cache management. the drive spins down possibly before pending changes are written out so unmounting has to ensure that later by waking up the disk and commit the changes. also drives can spindown themself without OS intervention (see hdparm -S docs). -- "Safely remove drive" is waking-up my external HD https://bugs.launchpad.net/bugs/539064 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

I think you're right, but ntfs is not the only journaling file system for Ubuntu. so your suggestion should apply to all of them, right? -- "Safely remove drive" is waking-up my external HD https://bugs.launchpad.net/bugs/539064 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 539064] Re: "Safely remove drive" is waking-up my external HD
I think this is the expected behavior of journalling file systems. When you unmount a writable file system, the file system needs to write out a marker saying that it was shut down "cleanly" and doesn't need a journal recovery on the next mount. Perhaps a file system could detect that it's been idle for some period and mark itself clean automatically. For the feasibility of this, you should contact NTFS-3G developers instead. Maybe assign to ntfs-3g? ** Tags added: ntfs-3g unmount -- "Safely remove drive" is waking-up my external HD https://bugs.launchpad.net/bugs/539064 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

seems rather an issue lower in the stack than nautilus then, reassigning to udisk for now... ** Package changed: nautilus (Ubuntu) => udisks (Ubuntu) ** Changed in: udisks (Ubuntu) Status: Incomplete => New -- "Safely remove drive" is waking-up my external HD https://bugs.launchpad.net/bugs/539064 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 539064] Re: "Safely remove drive" is waking-up my external HD
When using the "Palimpest Disk Utility", "unmounting" the partition causes the wakeup and "detaching" it causes the power-off.

thank you for your bug report, is the issue specific to nautilus or do you get it in when ejecting on a command line or in the disk utility dialog? ** Changed in: nautilus (Ubuntu) Importance: Undecided => Low ** Changed in: nautilus (Ubuntu) Status: New => Incomplete -- "Safely remove drive" is waking-up my external HD https://bugs.launchpad.net/bugs/539064 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
