Upgraded to 12.04 & my 2nd hardrive doesn't appear anymore

[Ed W.]

I upgraded to 12.04 LTS and installed the updates, but my second hard drive doesn't appear anymore. How make it appear? Its not listed under Devices like my other hdd. But it does appear in the Bios.

hi ! Ed W.

Do you mean to say that the 2nd hard drive does not even appear in the file manager ?
How do you want the drive to mount - manually on demand, or automount on startup ?
Please provide the output of terminal codes:

sudo fdisk -lu
sudo blkid
cat /etc/fstab

and we will see what we can do.

just try'n to help

Bashing-om,

Yes, the 2nd hdd doesn't appear in the file manager. And I'd like to mount it on demand. Thanks for the help.

If you do not see your Windows' partition in ubuntu's file manager, there is a problem we will have to explore:





Using the File Manager

For those using a desktop version of Ubuntu, or one of its offical derivatives, the easiest and quickest way of mounting NTFS or FAT32 partitions is from the file manager: Nautilus in Ubuntu, Thunar in Xubuntu, Dolphin in Kubuntu and PCManFM in Lubuntu. Simply look in the left pane of the file manager for the partition you wish to mount and click on it - it will be mounted and its contents will show up in the main pane. Partitions show with their labels if labelled, or their size if not.
Unless you require your Windows partition - or a NTFS/FAT32 partition for data shared with Windows - mounted every time you boot up for one of the reasons given below, mounting from the file manager in this way should suffice.

In your "fdisk" output the header info for "sda" is not present, I would like to see it; Merely for verification reasons - I am surprised to only see one partition on that first disk - sda ->NTFS Windows -. The second disk - sdb -> ext4 (Linux) - contains your ubuntu installation.

Post complete output of terminal code:

sudo fdisk -lu

everything will come up rosy
