I have the same bug with Lucid LTS (no RC or Beta) 32 bit desktop.
Installed yesterday,with external USB hd.
Bus 001 Device 011: ID 05e3:0702 Genesys Logic, Inc. USB 2.0 IDE Adapter
Please let me know what info do you need.

Before lucid I was in Slack 13 with kernel 2.6.33.1 and the hard disk was fine.

I have same bug with Lucid LTS, too.
It could be seen on screenshot attached.

[Richard Logan (richard-logan)]

I have this bug when removing an external usb hard-drive/media player on 64 bit Lucid Lynx.

First time I have had this issue on Ubuntu, never occurred from Feisty to Koala.

[Zacon Ion (promix)]

same problem when we want to safety remove any USB flash drive

[Zacon Ion (promix)]

My computer parameters are:CPU AMD Athlon(tm) II X2 250 Processor Socket AM3, Motherboard ASUS M4N78 SE, Memory RAM DDR2 4Gb, Video Asus EN9800GT(nVidia GeForce 9800 GT 512MB DDR3)...

[Zacon Ion (promix)]

Poate problema e din cauza driverelor din kernel?

[Zacon Ion (promix)]

Maybe the problem is because the kernel drivers?

I just noticed that it only happens when I unmount NTFS formatted external disks. Here's a screen capture.

[Ali Kara (alikara)]

My external drive is formatted by FAT32 but the same problem occurs.

[Larry Tate (cathect)]

I can confirm this as well using 10.04 for a USB connected external hard drive.

[sandoz (subs-webfusion)]

I get this problem when using an external dvd writer. The device is unusable after being fine initially.

[xtracool_protik (protik-seeker)]

I've this issue with one of my USB HDD. I thought formatting it can resolve it however even gparted can't umount it.
Here is gparted output on umount
 Text ended before matching quote was found for ". (The text was 'sh -c 'umount -v "/media/P'TIK"'')
 Hope this helps someone understand the problem. I may start a thread on forums as well

[xtracool_protik (protik-seeker)]

even formatting didn't help me -- right click and format worked but still can't safely remove the drive

[EowynCarter (tsunade30)]

I have a pretty similar message when unpluging my Archos IT

"" Error detaching: helper exited with exit code 1: Detaching device /dev/sdb
USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-4)

Others usb device unplug ok.

[Sebastien Bacher (seb128)]

seems rather an udisks than nautilus issue there

[Chris Hollenbeck (chris-hollenbeck)]

I just had this happen two different times when trying to 'safely remove' my Barnes and Noble Nook eReader.

"Error detaching: helper exited with exit code 1: Detaching device /dev/sdc
USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-1)
SYNCHRONIZE CACHE: OK
STOP UNIT: FAILED: No such file or directory"

I have not had any problems with my Sansa Fuze media player or my Lexar JumpDrive USB drive.

[marco (nazgul17)]

My external NTFS HDD (and only it!!) is affected by this error in Ubuntu 10.04... Any time. Hope this can help...

[Vampiur (vampiur)]

Same bug when i try safe remove Nokia n95 8gb

[Militi Luca (ubuntulukafulmine)]

i have the same problem with ubuntu 10.10, i have an external hdd western digital 500gb (WD5000AAKB),and this message appears everytime i want to remove the hdd from the usb.

[jan van stek (jan-vanstek)]

<email address hidden>

i get the same errormessage (synchronize cache :failed etc...) with an external HDD
connected with USB 3.0 !!!

[Pedro Bessa (deltrem1984)]

I plug Kindle DX in my computer, Kindle's desktop icon appears, I right-click it, then click safely remove the unit, then get the error message:

Error detaching: helper exited with exit code 1: Detaching device /dev/sdb
USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6)
SYNCHRONIZE CACHE: OK
STOP UNIT: FAILED: No such file or directory

What should I do?

[Rainer (r-e-l)]

I got the same error.

I own 7 usb drives. on 5 the safely remove the drive works without any problem. on 2 I got tha error. One of those 2 drives are 5 years old and the other is 3 month old.

This problem must belong to some hardware features or custimatuzaion features.

Hope this helps to analyze the problem. I will futher investigate to see any difference between the drives.
