What format are/is the partition/s?
When you last unplugged it, did you safely remove it or did you just yank it out?

One is NTSF, the other one is FAT, and the pen disks all all FAT... I just tried everything on another computer running windows and the all work perfectly, as they did befor installing ubuntu. Sam goes with the DVD player, if I put i cd in it, nothing happens...

Just tried another pendisk that yesterday worked perfectly on my girls laptop, which is running ubuntu, and still nothing happens

When you unplug it, do you safetly remove the device or do you just pull it out?
I suggest you also chkdsk the partitions in Windows to be sure they are ok

leonardo (leox85) said : #5

everything done safely averytime.. but as I said I dont think is a problem due to my HD, since everything worked fine before and still does. It's just the software that does not see anything when I plug it..

Its worth checking, just to be sure

leonardo (leox85) said : #7

Checked it everything fine but still no sign of life forme any drive

When you plug it in, wait 10 seconds and run:

sudo fdisk -l; mount; lsb_release -a; uname -a

What is output?

Thanks

But it still does not see the pen drive

With the Tb USB you can use:

sudo mkdir /media/1Tb; sudo mount /dev/sdc1 /media/1Tb -o rw,user,uid=1000

It should mount it

leonardo (leox85) said : #15

Ok the 1tb disk is now working
but for the 2tb disk this is what it says

Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

as for the usb flash drive is still not seeing any, same with dvd writer

leonardo (leox85) said : #16

Ok I made it for the second HD to work... now just prolems with pendrive and dvd..... Is it possible to change the name I gave to the HD???

I suggest you add an entry for the 1Tb in /etc/fstab to make it mount. I suggest you run:

sudo blkid

and use the UUID of the partition, it will then be used each time.

Can you help with this problem?
