[opensuse] Autodisconnect of usb-disk-dock
Hi, In a thread about two months ago a USB disk-docking station was mentioned (Aukey Super Speed USB3.0 Dual Bay ...). I bought it, but I don't know what's happening with it. I wanted to use it as my backup-station for my NAS. I was testing it, but it was not reliable. So I tested it on my Opensuse 13.2 laptop. There it also has "problems". What happens is that after a while of not using it, the connection is dropped. I can't access it any more. I have to remove power and power it on again before I can use it. I was wondering if this is expected behaviour, or is the dock malfunctioning ? Any suggestions to investigate this further ?

I have one, but do not keep it connected, so I can't answer. does it disconnect with a disk in it? eventually I can try connecting it. After how many time do you experiment the problem? jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, there's a disk in it when it disconnects. I don't think it's usefull without a disk in it ;-). I'm trying to figure out a way to time when the disconnects happens, but I can't think of something. Today, I did three times an rsync of about 190GB to two different disks. That works fine. Since it takes some time to finish, I don't wait for it. When I came back and saw it was finished, the disk always was disconnected.

I use docks as usb devices, and never keep the drives into them

rsync as CLI? some utility have a "switch off the device when finished" :-) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't keep mine connected all the time either. I mostly bought it for cloning hard drives, which it will do without being connected to a computer. However, recently a friend bought a new Windows 8 computer and wanted Windows 7. I did use the device to delete all partitions and create a new one and format it. It worked quite well for this temporary use. As I stated in that original thread, the documentation for that device sucks big time. It would be impossible from the documentation to figure out if your problem is a feature or a bug. It is possible that it has an auto-shutdown feature built in for it's own protection. For an external disk for backup purposes I use a 2.5 inch hard drive in an external USB case that stays connected 24/7 with no issues. A permanent single hard drive for backup might not fit your needs but if it could it might be a better solution long term. -- A cat is a puzzle with no solution.

I have five 2.5" disks to do my backups to. They will be rotated every week (i.e. every week a different disk, which goes outside of my home). A 2.5" disk is compact and I do have some jackets for them, so a bit more protected than naked disks.

Koenraad. Hi The easiest way is to remove the power manager altogether, never close

AFAICT, it's nothing to do with power. My NAS never goes to sleep. My laptop also did not go to sleep. Maybe a clarification : when I said power off/power on, that's the dock, not the PC where the dock is mounted on.

This is possibly a feature of the dock. They spin down the disk when it's idle for a while. Some disks also can do that. Use "hdparm" to check the power status of the dock/disk. I don't remember the exact command line options; the man page and calling the command without options should help. The odd thing is that the disk should spin up by itself when you access it again. That takes a few moments. A simple "ls" of the folder should be enough to trigger this. The last thing to check is the disks temperature. Maybe the dock thinks the disk gets too hot and shuts it down. Regards, -- Aaron "Optimizer" Digulla a.k.a. Philmann Dark "It's not the universe that's limited, it's our imagination.

My way of seeing of some disk is present is do a "cat proc/partitions". The dock with the disk in it is gone. Is there a better way to see if there is a disk ? I'm going to try that hdparm, but with this you have to specify a device. I'm going to look if the device is still there. It will be this evening though. Thanks.

You can use "lsusb" to see whether the USB device is still there. "lsscsi" will help you see disk-like devices "lsblk" shows any kind of block device I'm not sure what /proc/partitions contains; I've never used it. Try different commands and also check the system log (dmesg, journalctl) and look for errors. Maybe Linux unmounts the device when it notices that it goes to sleep. That means the device will still be there (i.e. lsblk should still display it). Regards, -- Aaron "Optimizer" Digulla a.k.a. Philmann Dark "It's not the universe that's limited, it's our imagination.

I just got a message from the seller. It seems a feature : when the drive is not accessed for a while, it goes in stand-by. But when there is no possibility to get it out of stand-by without powering-cycling the device, it's useless for me, wasted money. So beware when buying this device !
