Hi!

I have USB external hard drive that before I have Bubba was connected to my Win desktop PC. Now I connected them to Bubba without problem by using Admin Web interface.
But of course I would like to do that on reboot. So I found descriptions about automount.
But I would like to make it so that outomount also happens when I disk hardware is connected. In my case that disk is enough noisy - so I would like to switch them off and then switch back without touching admin web interface.
Probably another economich solution could be spin down on inactivity - is it possible on USB disks?

Found myself:

First make directory where your usb drive will be mounted. I made usb_h in /home/storage/extern
Give apropriate permissions by chmod.
Find your USB volume label: Add into /etc/fstab (f.ex. nano /etc/fstab) follwing line: But it works only for boot time, when HD is disconected or switched off then it does not automount.

you can use usbmount or ivman for automounting.

I am more looking now for some way how to auto spin down after some time that external USB HD. Then I could leave them untouched.

hdparm may be able to spin it down.

hdparm may be able to spin it down

Allready tried - unsuccesfuly.

Gave some kind of incompatibility error.

Also tried one spindown utility - accepts command, but no result.

Now I am trying spindown from:

But I hooked on makeing when got following problem:
make: g++: Command not found

But I have GCC...

Hi!

How to correctly give permissions for attached USB drive?

Is it fstab, mount point or disk (/dev/sdb1)?

I tried permision commands on mount point but nothing happens when disk is mounted.

Now mu usb disk is readonly, but I would like also write access.

Thanks in advance!

Found already:
For my disk vfat in fstab there should be umask=000, f.ex.:

LABEL=your_label /home/storage/extern/usb_h your_disktype auto,umask=000 0 0

Yes. Spinning down usb disk can be hard. But there are disks that can be configured to spin down after f.ex. 15 minutes idleness. F.ex. Maxtor OneTouch 4 disks.

Solved by using Spindown daemon from:
http://code.google.com/p/spindown/

Also from there I learn correct command for spinning down (at least for my Buffalo drive station external disk): Note: This is good only for external HD, that you don't use frequently. Too often spindowns/ups will short life of your HD.

Thanks!

FWIW, I recently tried enabling the auto-spindown built into the kernel driver, but couldn't get it to work. Whereas "sg_start 0 /dev/sdb" works fine to spin down. Spin-up is automatic, i.e. on first access to the drive. Great.

Using just the sg_start command, you could even simply add a periodic crontab entry to spin disks down, e.g. at night.
