I am trying to get Fedora core 2 to see a external usb hard drive
(Maxtor 300Gig). I have tried to follow directions on this web site and
others and set
this up but to no avail and/or success. I have attached the following
files to this email so you can see what I've been doing. I thought that
FC2 would be better for USB support but I guess I have some more work to

do. Let me know what you think. Thxs all.

p.s,
  My device is reconized as /dev/sda when I do a dmesg and I made a
directory called /mnt/usbdisk
  but these didn't fly.

Instructions for attaching a USB mass storage device:
*****************************************************

1. Inspect SCSI devices
2. Find exact path (/dev/???) for the USB mass storage device partition
3. add info to /etc/fstab
4. mount
5. done!

********
keywords: mount usb mass storage scsi fstab
********


Step 1:
********************************************************
to inspect the SCSI devices: (USB disks map onto scsi)
cat /proc/scsi/scsi

note the number of your usb device (eg: scsi3)


Step 2.1:
********************************************************
inspect the kernel messages logged when connecting the usb device:
dmesg

look for the following:

The marked line above indicates our USB device is on /dev/sdb



Step 2.2:
********************************************************
to inspect the partitions on the USB device:
fdisk -l /dev/sdb

Disk /dev/sdb: 40.0 GB, 40020664320 bytes

now we know that the partition is in /dev/sdb1

http://www.linux-usb.org/USB-guide/x498.html recommends:

mkdir /mnt/usbdisk
mount /mnt/usbdisk


Step 5:
********************************************************
Find your USB disk mounted at:
/mnt/usbdisk


NOTE: I think one needs to unmount before powering down:
umount /mnt/usbdisk
