I have two devices connected to my usb ports one is a mouse and the other is a fan for a laptop.
I looked on the left side of dolphin and opened sysinfo:/ and i cant see them anywhere to unmount them, when i want to remove them?
how do i safely remove hardware
thanks
It is probably okay to just unplug them.
Unplugging a usb mouse is fine. I assume the same applies to a fan.
It is for disks, that safe removal is important. That’s because there may be buffered information that needs to be written back to the disk to maintain file system integrity. That problem does not exist for a mouse, and presumably not for a fan either.

I agree with nrickert for fans & mice. There is most likely nothing to be harmed by removing them, though removing your active mouse might not do what you want. For hard drives that are connected by USB, look at the Device Notifier in the icon tray on the bottom right. It uses the USB symbol. Select it once with your mouse, that is still connected and use the Eject symbol just to the right of the USB drive to first umount it (eject) and then you can safely remove it. Also, there is no command called unmount device, just umount with no added n after the u.
Thank You,
That’s good to know! I’ve always been careful to drink all the coffee before unplugging my USB coffee warmer. I could have avoided a lot of jittery nerves if I had known earlier.

sometimes i think you need to be locked up (like me)

Love the chatter, but someone should point out to the OP that the fan is just
getting power from the USB port. The host system doesn’t see it in any way -
plugged or unplugged!
Shhh, they might take away my Internet browsing privileges at this asylum. 
Yes, you are absolutely correct, the fan just uses the 5V power lines and doesn’t affect the computing capability. However USB controllers can also sense if if a device is drawing too many mA and shutdown the port if so. But that doesn’t put the fan at risk of “losing data”. 
my external hardrive isnt noticed in the device notifier, it say no devices available. i can view files and folder in dolphin and unmountit there but i cant eject it in the device notifier
thanks

We must ask what type of hard drive that this is? Specifically, is this a USB 3.0 adapter and/or USB 3.0 hard drive? Consider that we use USB hard drives and thumb drives all of the time with openSUSE 11.4 and only USB 3.0 have shown any sort of issue which can be overcome. Otherwise, this is some other issue we are not seeing from your messages. Does the drive work with Windows? What kind of disk partition is it? How many partitions exist on this hard drive? What brand and model USB hard drive are you using?
Thank You,
i thinking its my esata port, does esata need drivers installed from the repository?
the harddrive was plugged in thru my esata port and one usb cable connected to a usb port for power, nothing is shown in device manager but can see the hardrive files and folders from the external hardrive in dolphin after i authenticate by typing in my root password but still not in device notifier,
when i put the harddrive directly connected with only the usb ports everything works fine?
thanks

So, when you say eSATA, which I guess I missed, hot plugging it in and out is not normally possible. So, plug in the eSATA hard drive and reboot openSUSE and leave it there and do not remove it. To use the drive start:
YaST / System / Partitioner & answer yes to the next question.
Next, in the left window, open up hard drive(s) and select the drive name of your eSATA hard drive. It could be sdb or sdc, I don’t know for sure what it will be called on your system. In the hard disk window on the right, put your mouse pointer over the existing partition, right click your mouse and pick edit. In the edit partition window under Formatting Options, the Do Not Format bullet will be set. Do Not Change this. In the Mounting Options window, select the Mount Partition bullet and enter a location for it to be mounted such as /Software or /Multimedia or /DataSafe or /MyStuff or what ever you want to call it that does not exist at present. The slash indicates where it is mounted from the root. Press the Finish button on the bottom right. Then press the next Finish button also on the bottom right. The new Folder name you selected will be created, the partition will be mounted and an entry for you will be made in your /etc/fstab file. Make sure this eSATA drive is plugged in before you start or restart openSUSE each time.
Now, when you start the Dolphin file manager, just look for the folder name you selected for this drive and it will be there.
Thank You,
so is it that esata drives don’t mount automatically and I would have to do it manually every time I wanted to access it, if i didn’t do this step?
since my external hard drive when plugged in thru my USB ports is located in /root/media, to keep everything in one place can I also put my esata drive location /root/media/eSATA5C88EDE988EDC21E i was thinking about naming it 5C88EDE988EDC21E, the same name given to the drive when mounted the eSATA drive manually but would that conflict if I attached the drive into the USB ports instead of eSATA?
thanks

Thank You,
Do a search for “eSATA hot plug”.

ken_yap, go for if you can, using your hard drives and openSUSE.
Thank You,
Don’t need to, I have USB3 drives and eSATA seems to have stagnated. However, eSATA is designed to be hot plugged without electrical problems if the motherboard supports it. Software support may be a different matter. Designers usually expect that when you put an external connector that is easily un/plugged, people will do so.

So I have tried eSATA with Hot-Plug and it would not eject and was fluky at best on plugging in. I had to set the BIOS to support Hot-Plug as well. Its surely possible that different hardware chipsets or kernel versions might work better, but in the end, if you want to use eSATA, treat it as if installed internally for now. Boot with it connected and leave it that way. If hot-plug is your wish, stick with USB would be my advise. I would also concur on using USB 3.0 as it has worked just fine for me, including doing a hot plug. My only issue with USB 3.0 was with openSUSE 11.3 and kernel 2.6.34 which would not mount a USB 3.0 drive from the fstab file. Kernel 3.0 seems to be much faster with USB 3.0 than when I first tested this device.
Thank You,
I was just pointing out that there is a difference between personal experience and published specifications. You can’t deduce the latter from the former. However if the latter doesn’t perform you can blame the implementation.
[FONT=Calibri]my eSATA drive was recognized in the yast partition. Is it normal that opensuse doesn’t mount it automatically in the the mount point of yast or is it that my motherboard doesn’t support mounting eSATA automatically? I read where an external eSATA hard drive is just like an internal drive. So can you just plug it in when the computer is off and unplug it after shutdown?
Is hot swap dependent on the SATA driver something on my motherboard? if I don’t get the option of device notifier recognizing it, does that mean its not supported?
thanks
