Hi folks,

FC5_64

Just install an USB enclosure (ATA HD)

# fdisk -l
did not find it.

Please advise how to get it installed. TIA

What does lsusb say?

Do dmesg or udevmonitor show any action when it's plugged in?

Are you sure the hard drive is working and formatted?

Hi David the H.

Tks for your advice.

Problem solved after running

# fdisk /dev/sdb
to remove partition.

Then ran
# mke2fs -j /dev/sdb

Now the USB enclosure can be detected whenever plugin

# cp /home/satimis/enclosure.txt /media/disk/
# ls /media/disk/

Code:

enclosure.txt  lost+found

It is now ok

As user
$ cp enclosure.txt /media/disk/

Code:

cp: cannot create regular file `/media/disk/enclosure.txt': Permission denied

I can't copy file on the USB enclosure but I can read it.

Where can I set the permission. TIA

Glad to hear you got it working.

Permissions can be set during mounting or in /etc/fstab, usually by adding the 'user' option. But if you use automounting, it probably will require placing options somewhere else, and I'm not sure what you'd need to do.

(That's one current annoyance with Linux; there's no single, standard way to automount devices right now.)

lsusb is part of usbutils. At least that's the package name under Debian.

You'll only have udevmonitor if you're using udev, which most recent systems do, but older ones may not. It can only be run as root by default in any case (/usr/sbin/udevmonitor). When running, it displays what's happening as you add or remove devices and the /dev entries that get created or removed in response.

I'll use the USB enclosure as portatble storage device on WindowsPC and LinuxPC, but having not figured out following points;

1) FAT32 is running on My WindowsPC, therefore I'm prepared to format USB enclosure as FAT32 system. However can files on ext2/ext3 system be copied/edited on FAT32 system?

2) Can I run following commands to format the enclosure without going to WindowPC?

Code:

# mkfs.vfat -F 32 /dev/sdb

TIA

I have the package installed.

# lsusb

Code:

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 002: ID 045e:00b9 Microsoft Corp. Wireless Optical Mouse 3.0

About "udevmonitor"
# which udevmonitor

Code:

/usr/sbin/udevmonitor

It is already running.

# udevmonitor

Code:

udevmonitor prints the received event from the kernel [UEVENT]
and the event which udev sends out after rule processing [UDEV]
-

It only hung here.

# udevmonitor --env

Code:

udevmonitor prints the received event from the kernel [UEVENT]
and the event which udev sends out after rule processing [UDEV]
-

It also hung here

Others noted with tks.
