 |
|
Hi,
since it's very popular  I have an external HDD being adapted through USB to my system. It's a 80 GB drive.
There is no problem when mounting it without help of udev. In this case the partition table is fine and fdisk finds the 80 GB storage volume.
| Code: |
Aug 29 19:41:24 dionaea SCSI device sda: 156368016 512-byte hdwr sectors (80060 MB)
Aug 29 19:41:24 dionaea sda: assuming drive cache: write through
Aug 29 19:41:24 dionaea usb-storage: queuecommand called
Aug 29 19:41:24 dionaea usb-storage: *** thread awakened.
Aug 29 19:41:24 dionaea usb-storage: Command TEST_UNIT_READY (6 bytes)
|
However I actually want to use udev. I map the drive to /dev/usb/hdd. Now `fdisk /dev/usb/hdd` only finds ~ 5 GB. Furthermore it cannot write the partition table correctly so I think there could be an error with udev and -maybe- the way it creates the block device file.
There are effictively no hints shown in the kernel log. 
Does anyone have the same problem and knows how to solve or circumvent it?
Thanks...
Georg

You sure you don't have a 4.7GB dvd in your dvd-writer on /dev/hdd?
And what's wrong with simply using /dev/sda to access the external harddisk?

No. There is no connection to the dvd drive. It seems to be another issue.

There is absolutely nothing wrong with that except the thing that I'd like to mount the drive with udev to have it always on /dev/usb/<defined point> mountable. This should be a disk to be used as backup device. Using USB there is no way of knowing if the device is /dev/sda, /dev/sdb, and so on. :-/

Hm, I've completely formated the drive without udev (80 GB).
Now plugged the drive in, mounted it using udev and its 80 GB volume are shown.
I'll watch this for a time -- though my problem is solved for now, I'm not sure if it is for long...
