I recently installed SimplyMepis 6.0. When I plug in my pen drive, it recognizes that and mounts the drive. I am also able to read and write from the drive.

However, I am unable to unmount the USB drive. When I right click & select "Safely Remove" or run umount from terminal window it gives an error that the device is in use. I have ensured that there are no files open and have closed the File Manager.

Please let me know if I am doing something wrong. Currently, I need to shutdown the machine and then remove the USB drive.

TIA,
Sathya

try to close the applications that are accessing the device.

you can also know which applications are using the device by doing where device is the node name of the device.

close the applications then try to unmount the device.

you can mount it manually too by doing Edit: just found out, fuser /dev/device won't work, try fuser -m /mnt/usbmountpoint instead

I find that sometimes, Konqueror won't let go of the USB drive. In that case, I need to close one or all of the Konqueror windows before unmounting it (by opening a new Konqueror window and then doing the "safely remove" thing, if I had closed all of the Konqueror windows).

Thanks konsolebox & IsaacKuo.

I will try the suggestions and keep posted on if that helps resolve the issue.

Thanks again!
