Hi,

I have read a bit about hard drives and scsi and I used

root@debian:~# cat /proc/scsi/scsi
Attached devices:
root@debian:~#

My sheeva plug has the original linux from vendor GlobalScale Technologies.

My hard drive is a Iomega Prestige 500 GB hard drive.

I think I need usbfs driver or subsystem, as another usb memory stick is not detected.

Are there any documents how to getting a usb drive running on the base system?

Also I now have seen a message that makes me worry:

Apr 28 02:00:36 debian kernel: JFFS2 notice: (666) check_node_data: wrong data CRC in data node at 0x1cc57800: read 0x41e30dc0, calculated 0x4add1735.

Thanks

Hi,

after some tries I got the drive running. But I needed to unplug my hub and then plug it again.

I have added the wait4usbdisks script mentioned in this forum but it seems not to work.
As my drive spins down very early I think doing a USB power down and up and then a mount -a
in a script instead of only waiting for a drive to be online.

wait4usbdisks: http://plugcomputer.org/plugforum/index.php?topic=485.0

What do I need to power up and down the USB bus?

Can I use dbus commands for that?

Any comments?

Thanks
