My problem: a partition and its files disappeared unbeknownst to me, most likely after updating from 12.10 to 13.04 (though not sure).

Before Ubuntu 12.10 I was running Windows 7, with a hard drive of 250 GB partitioned in two: drive C and drive D. The former for system files, the latter for personal files. I formatted the C drive and installed Ubuntu 12.10 onto it from a Live CD. Afterwards, drive D and its files were available under an icon in the launcher, similar to the one that appears after connecting a USB stick or an external hard drive. The drive was also available through a folder in home\media.

The first moment I noticed it gone was after the update to Ubuntu 13.04. It's gone. I have done nothing I can think of to trigger it. I ran multiple searches on the entire filesystem querying filenames I surefire knew were on that partition, with no result.

Anyone can help?

EDIT 1: release upgrade was done via the default software updater from within Ubuntu 12.10

EDIT 2: Output from sudo fdisk -l via terminal:

From the output of requested commmands we can see that your Windows partitions had accidentally been repartitioned.

In case you have no backup data you will have to

Stop using the drive

then follow the answer to this question to recover your data:

Thank you for your help. Is there any way I could notify Ubuntu developers about this obvious "glitch"? I mean, during the upgrade I have been in no way prompted that repartitioning would take place. All I did was click "Yes" in a window that asked "There is version 13.04 available. Do you want to upgrade?". I think there should be at least a mention (if not a downright red flashing banner) that data may be lost. –  porcoazurro May 6 '13 at 19:57
    
You may report a bug - likely against "ubuntu-release-upgrader-core" –  Takkat May 6 '13 at 21:49
