System not recognizing external HD on restart.

[nlambert]

Hello!

My system doesn't recognize my external HD when I restart. I have to unlug and replug it in every time. Is there a command I could add to startup apps that would do this for me?

Thanks,
Nathan

After some more searching, I found out about the storage device manager (pysdm) and about editing fstab manually. Still, I cannot get the external to mount automatically on startup.

When I reboot I get this during startup:

The disk drive for /media/myexternalhd is not ready yet or not present

and when I try to open pysdm, it doesn't respond unless I unplug and replug in my external. I don't even see it listed when I type in ls -l /dev/disk/by-uuid

From what I can tell, it does no good to edit fstab or use pysdm because the computer doesn't recognize the external until I have unplugged/replugged it.


.... any ideas, guys?

partprobe

I looked into partprobe, and it doesn't look like it will help me with my problem. I can't do anything like:

partprobe /dev/sdb1

because my system doesn't even recognize sdb1 or the device's UUID as being there until I unplug/replug my HD.

It is listed when I use lsusb whenever it is plugged in, regardless of whether I unplugged/replugged it or not.

sudo partprobe looks for all partitions - do not put anything after it.

thanks for the replies dcstar.

i did sudo partprobe and it just hung for 2-3 minutes, and went back to prompt- no output.

i wonder if all of this has something to do with a power-saving feature of the drive (it's a seagate freeagent HD):

i connected it to my windows machine, and disabled the power-saving mode. also, i got sdparm and ran sudo sdparm --clear STANDBY -S /dev/sdb

starting to think that there is no solution.

I know this might be sloppy, but is there a command I could run on startup that would simulate unplugging/replugging in my HD?

It is listed under lsusb as:

Bus 001 Device 005: ID 0bc2:2300 Seagate RSS LLC

Thanks.

There is no output, this shows a summary of detected partitions:

sudo partprobe -s
