Re: USB hard drive - external...

Because of mindless "fiddling" by me, I have had to do a complete reinstall
of LinuxMint upon my Desktop computer. Fortunately I had a backup, on an
external USB hard drive, including hidden folders of the major programmes I
use.

The reinstall was successful but for some reason the computer will not read
the USB HD. It did before without me having to do anything especially
"Linuxie". I have unplugged and plugged in the drive both at the drive and
the computer connections, without success. The hard drive light is on.

I have searched Google for "mounting external usb drive" but without
success.

If I go into a terminal and type lsusb i get

zed@zed-desktop ~ $ lsusb
Bus 002 Device 004: ID 058f:6387 Alcor Micro Corp. Transcend JetFlash 110
USB 2.0 Flash Drive (2GB)
Bus 002 Device 003: ID 05e3:0702 Genesys Logic, Inc. USB 2.0 IDE Adapter
Bus 002 Device 002: ID 03f0:2f17 Hewlett-Packard Bus 002 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000 zed@zed-desktop ~ $

if that is any use. All I can recognise is the usb flash drive and HP
printer. I presume that the USB 2.0 IDE Adapter is what allows the other
USB devices to register. The external hard drive doesn't appear.

So, your mission, should you choose to accept it, is to tell this
floundering geriatric what other avenues are open to him to solve this
problem.

Install a "proper" distribution?! ;-)

Plug in the hard drive, give it a few seconds, then do 'dmesg' - that should scroll loads of log stuff up your screen, but it's the last few lines you're interested in. It should register that a USB device has been plugged in. It should also say something about the nature of that device. Ideally, it should say it's attaching it to a scsi port.

So you know what you're looking for, this is what i get, when i plug in an ext3 formatted external hdd:

As you can see, it ends up by mounting /dev/sdb1. That's probably gnome's auto mount system doing its thing.

See what happens when you do the same. If you can't get enough information from it to work out what to do, post *the relevant bits* here.

Regards from New Zealand on a very cold Friday evening, with gale force
winds and torrential rain expected from midday tomorrow :-(

I'm glad to hear that! It's lovely here at the moment. I'm off for a swim in the river estuary soon! The only reason i'm gloating is because i normally live in Aus and the weather here is usually worse than it is there! ;-)
