gparted, Under the 'Device/Attempt data rescue' dropdown can attempt to
find things.  Don't think it can recover, but it can mount them so you
can copy off.

Backing up a bit, first let me explain a bit about the icon (or at
least, what I think you're talking about)

So, some systems, when they detect a mountable partition, will put an
icon on the desktop that allows you to click (double-click?  whatever)
it and get the partition mounted.

A partition which is already mounted is, by definition, not mountable
(slight white lie).  So, that same system (should) remove the icon since
the partition is not mountable.

So, that's why the icon goes away when you mount it manually.

So, don't let that distract you from the major quest, which I believe is
to make the partition 'work normally'.

First, when you mount it from the command line, do you get a warning of
some kind?

If not, type 'mount |less' (or, if you just mounted say /dev/sdb1, say
'mount | grep sdb1') and find your device - does it say ro or rw
somewhere?  RO means read-only, RW means read-write. I'm guessing your
device will show RO and not RW.

(here's my /dev/sdb2, mounted normally:

/dev/sdb2 on /home type ext4 (rw,relatime,errors=remount-ro)

Note the rw.  Mounted 'badly' would be:

/dev/sdb2 on /home type ext4 (ro,relatime,errors=remount-ro)

Before you proceed, I highly recommend doing an image backup of the
device.  If you have space on your hard disk, do the following unmount
the partition (again, let's say it is /dev/sdb1), then make the image
copy: dd if=/dev/sdb | gzip > my.device.backup.dd.gz

This uses DD (HIGHLY recommend you check out ddrescue as a better
alternative!!!!!) to copy, bit-for-bit, everything on the device
/dev/sdb (note the whole device, not the partition.  You can also copy
just the partition, which may be useful for other things, by using the
partition (/dev/sdb1) instead of the device).  By not giving dd an 'of='
argument it sends the data to standard output, which you then compress
and put into the backup file.  If the worst happens and your recovery
efforts destroy the data on the device, you can restore it.  One reason
for ALSO saving just the partition is that you can create a partition
somewhere on a disk and write that partition image there...

Ok, so you've got your backup.  You can try fsck and whatever else
(someone says that 'disk drill press kit' can do wonders, I have not
tried it myself) to try to fix the problem.  A lot depends upon what
mount said when you mounted it manually.

Worst case, copy all the files off the device.  Make sure everything is
there...  then either get a new drive and put the data on it, or
reformat the old one.  I tend to keep old drives in that state laying
around, but then if you did the image backup with dd you have, in
effect, the original device just without the hardware...

Hopefully enough of that made sense to get you going!
