problem getting USB HDD to work

haimat · 04-25-2005, 07:37 AM

Hi all,

recently I installed Slackware 10.1 on one of our servers, now I want to
backup it's data to an external USB HDD (Western Digitial w/ 250 GB).

I included USB and usb-storage support into kernel, started hotplug, and
get this messages in /var/log/debug

Code:

Seems there is an error, I can't access the drive. I use Kernel 2.4.29
from Slackware CD-ROM.

Any ideas on this?
TIA and greetings, Matthias

Did you enable SCSI support? You need this for USB drives

haimat · 04-25-2005, 08:14 AM

Yeah I enabled it, because I am using a 3ware SATA RAID1 controller, which needs
SCSI as well. I access this RAID1 via /dev/sda ...

update: after attaching my USB drive to a windows machine and re-attaching it to
the Linux server afterwards, I get other messages now from syslog:

Code:

Apr 25 15:24:40 server kernel: WARNING: USB Mass Storage data integrity not assured

Apr 25 15:32:19 server kernel: WARNING: USB Mass Storage data integrity not assured
Apr 25 15:32:19 server kernel: USB Mass Storage device found at 2

And now I can see my drive under /proc/scsi/usb-storage-0/1 as well:

Code:

   Host scsi1: usb-storage
       Vendor: Western Digital
      Product: External HDD
Serial Number: 5743414C3733343435313139
     Protocol: Transparent SCSI
    Transport: Bulk
         GUID: 105804023733343435313139
     Attached: Yes

But I sill can't mount the drive.
Any ideas? Greetings, Matthias

How are you trying to mount the drive?

haimat · 04-25-2005, 09:09 AM

I was looking for a new /dev/sdb device or something similar, but it seems there is
none. Shouldn't dmesg give a output like "Attached scsi removable disk sdb ..."?

I try to mount the HDD via:

Code:

root@server:/dev# mount /dev/hdb /mnt -t vfat
mount: /dev/hdb is not a valid block device

The same goes for /dev/hdb1
vfat is included in my kernel

Any ideas?
Greetings and TIA, Matthias

info: the disk does not show up in my scsi device listing, only my
RAID1 on 3ware controller.

Code:

root@server:/dev# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: 3ware    Model: Logical Disk 0   Rev: 1.0

Okay, is it found by "lsusb" as well?

Do you have a dynamic /dev manager (such as udev) that will create /dev entries for you? If so, does it have rules for USB hard drives? If not, you may have to create them manually.

haimat · 04-25-2005, 10:01 AM

Code:

root@server:~# lsusb
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 003: ID 1058:0402 Western Digital Technologies, Inc.

slackware 10.1 uses udev, and it seems to be configured for USB devices:

Code:

# USB devices
KERNEL="hiddev*",       NAME="usb/%k"
KERNEL="auer*",         NAME="usb/%k"
KERNEL="legousbtower*", NAME="usb/%k"
KERNEL="dabusb*",       NAME="usb/%k"
BUS="usb", KERNEL="lp[0-9]*",   NAME="usb/%k"
