usb stick will not stay unmounted with safely remove

This same behavior also happens with a usb hard drive.

Don't see that behaviour at all on a stock maverick, fully updated thru 07/21

All flash and ext. usb drives are removed (safely remove,,), with no issue, have various types and file systems inc. Fat 16, 32, ext2, ntfs

Overall the eject command has become somewhat worthless and does leave an icon behind in 'Computer' (unusable

the only apparent value to eject is to 'eject' the isofs (cdrom) on sandisk U3 drives while leaving the storage device mounted and addressable.

I run on a usb HDD with several testing OS' installed. Using "safely remove drive" is very handy. Use it and the entire HDD is removed.

It is easy to tell that it is removed as the screen goes blank when the OS that I am using is also removed.

A simple fix would be to put the unmount option back in the menu.

I can confirm this behaviour on a clean installation of Maverick final. My USB stick remounts (Nautilus window popping up) when I select Safely Remove Drive on right-click menu. I miss the old unmount option, too. I'm running Ubuntu 10.10 32-Bit on ASRock Ion 330.

Maverick remounts the "Safely removed" usb device before it can be pulled out (< 1/2 sec)
at the first remove. The second remove attempt works properly on the usb
device.

I waited 5 seconds and pulled out the stick.
I haven't waited longer to see if it eventually remounts.

My USB stick remounts when I select Safely Remove Drive on right-click menu. I'm running Ubuntu 10.10 Maverick 32-Bit on Zotac nForce 610i ITX.

Please See http://www.youtube.com/watch?v=UMKrwSECx9E

The remount does not occur until after the first time update-manager is run on a new Maverick install.

I see the same behaviour as Ubfan - first attempt at using the "Safely remove" context-menu option results in an immediate re-mount, the second attempt sees the device remain un-mounted.

I also see the same behavior as Ubfan - it takes two repetitions of "Safely Remove Drive" to actually remove the device. I have tested this on several flash drives and an external usb hardrive that I use for backup.

Same behaviour for me on my ASUS M2NPV-VM motherboard.

Using safe remove remounts the usb key a few seconds after the action.

dmesg says:

[ 1262.979951] WARNING! power/level is deprecated; use power/control instead

hummmm, not really what we want :-(

I also have this problem. I can "safely remove" external drives (usb sticks, usb drives, encrypted or not) as often as I want, they keep reappearing. I have this problem on three completely different hardware platforms, so I don't think this is hardware related.

As dmesg shows, as soon as the device is disconnected by the kernel, it is detected as a new device.

[ 3126.770755] EXT3-fs (dm-2): mounted filesystem with ordered data mode

[ 3561.030818] usb 1-4.1: new high speed USB device using ehci_hcd and address 11

Same for me on Zotac GeForce 9300 mobo running 10.10. First time for this anomaly after many prior releases on same platform. Safely remove remounts drive just as though it were just plugged in.

This problem currently exists in Linux Mint Debian Edition (LMDE) as well.

I have a Western Digital USB 3.0 hard drive which remounts almost immediately when I click 'Safely Remove Drive'. I use Ubuntu 10.10.

Behavior confirmed on natty 11.04. I read that this may be related to NVidia USB chipsets, which I have in my computer.

Partial output from lspci:

00:04.0 USB Controller: nVidia Corporation MCP89 OHCI USB 1.1 Controller (rev a1)
00:04.1 USB Controller: nVidia Corporation MCP89 EHCI USB 2.0 Controller (rev a2)
00:06.0 USB Controller: nVidia Corporation MCP89 OHCI USB 1.1 Controller (rev a1)
00:06.1 USB Controller: nVidia Corporation MCP89 EHCI USB 2.0 Controller (rev a2)

This problem persists with Natty 11.04 with my ASUS M2NPV-VM which is based on Nvidia chipset

I think that there is a little problem with Nvidia's USB chipsets.

I always have this message on my dmesg:

[10420.100709] WARNING! power/level is deprecated; use power/control instead

Does anybody knows how to switch on power/control instead of power/level (to see if the problem persists) ?
