Ubuntu

usb hard drive not recognized at startup

Asked by buck2202

I have a Seagate FreeAgent 500GB usb hard drive that worked perfectly under Intrepid. It would recognize and mount it on startup if it was already plugged in, or automatically mount it if I plugged it in while the system was on.

Since upgrading to Jaunty, the drive is no longer mounted on startup. The lsusb command always shows that it is present, but blkid / fdisk -l don't show any information on it. Configuring fstab with the mounting information has no effect, and I can't mount it manually since the computer doesn't recognize it as disk space.

If I disconnect/reconnect the device after the system starts up, it works properly.

I've tried the drive on a different computer (also running Jaunty), and it mounts normally under both circumstances (present at startup, or plugged in later).

Just as a note, both of my computers are running clean installs of Jaunty. The non-working one with the amd64 version, the working one with i386.

Add usb_storage to /etc/modules - It should fix it. Bug 364933 is about this. If adding the module fixes it, can you please add a comment in there saying that you're experiencing it too, and that it's AMD64 (nobody in there is on AMD64 yet, I think).

It's odd that it works fine on another system. Wonder if there's a hardware difference for those of us who have it not working.
