USB HDD not mounted at boot [Solved]

[fire_dragon]

Dear friends,
I have 1xide hdd and 3xusb hdd.


usb hdd 1 is connected directly to the computers usb port.
usb hdd 2 is connected to a usb hub
usb hdd 3 is connected to a usb hub

ide hdd always works like expected, on this hdd linux is installed
.
usb hdd 2 always works, it will be mounted to the specific point whch I gave in the fstab file.

usb hdd 3 in 80% of the time will be mounted at boot correctly, and 20% of the time not.

usb hdd 1, which is directly connected to the computers usb, is mounted 30% of the time and 70% not.

If I unplug and replug the hdd 1 device, it will automaticly recognice it, but not mount it to the specific correct point.

I enabled the automount feature in KDE settings.

After a reboot, straight after the unsuccessful mounted startup, all 3 devices will 100% be recogniced correctly. Waiting at the grub entry for a longer time, will not help the problem.

Maybe I have to add some extra time at the recognition process of the usb devices at the startup?

The situation is now a bit annoying since I have to start the computer twice to make everything work. How to fix this issue?

Thank you.

I don't know how to help with your problem, but you could mount the drives manually instead of rebooting until you have solved it.

Thanks for the suggestion, but I figured out the problems cause now.

I have my USB hdds attached to a power splitter bar, when I power on the computer, it automatically switches the power of all other devices on. This time is not enough to spin up the harddisk fast enough to be recogniced by the bios. So when it starts into sabayon, it won't automount it. And it doesn't automount it later when its availible, even though I enabled this setting in the removable devices in KDE. When I start into windows 7, the drive is not availible for a few seconds, but windows will auto 'mount' it later to its drive letter, this is why the problem doesn't appear in windows notably, because I don't access the drive in the first few seconds.

Now I put the hdd to permanent power so the bios will recognise it.

This behavior was not there before, the usb hdd needs longer time to spin up and takes several tries to do so. I guess it is getting old and it will break soon, either the usb hdd case or the hdd itself.

Thanks for the help.
