I am entirely new to Ubuntu. I installed v14.04 LTS on the C drive of a functional PC which has a working D drive containing data. Ubuntu does not recognise it. I have looked at similar requests for help but have not yet succeeded in solving the problem. My partitions search produced this:

   11        0    1048575 sr0
      11        1    1048575 sr1
       8        0  312571224 sda
       8        1  309686272 sda1
       8        2          1 sda2
       8        5    2882560 sda5

What does this tell me and what can I do, please?

The result of sudo fdisk -l was:

Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes

/dev/sda5       619376640   625141759     2882560   82  Linux swap / Solaris

SOLVED after a fashion. There was no power to the drive! Presumably dislodged by replacing case. Ubuntu did not read it when powered up, so loaded drive into a dock on a Windows PC, reformatted it, Ubuntu now reads it OK. Will soon have to ask a new question about how to create a home network sharing Ubuntu and Windows. If only instructions were clear for us oldies! Many thanks for your help on this one.

  • What is the output of: sudo fdisk -l – Malachi Sep 28 '16 at 19:18
  • It shows one hard-drive sda with about 160GB capacity. The drive is divided in three partitions. sda1 has a size of about 158.5GB. sda2 seems to be an extended partition which contains sda5. sda5 has a size of about 1.5GB. Use another command to show drives. Run sudo fdisk -l in terminal and paste output into your question to be sure, I don't know which command you did use. – mook765 Sep 28 '16 at 19:20

    If you had a second physical drive it would show up in your fdisk output as /dev/sdb since this is not the case I can only conclude that your "D" drive was actually a partition rather than a physical drive and you mistakenly overwrote it when you installed. You are likely to be able to recover much of the data with ubuntu however.
