Please boot entirely from Ubuntu live install cd and select to try Ubuntu try to access to your partitions from it...

sorry that's not worked because it showing like as entire hard disk as only 3 partitions one is dev/sda of 100MB and dev/sda1 of 32GB and dev/sda2 of reaming 124GB under external
thank you for your valuable effort to fix this problem

please keep trying thank you very much

If you are installed Ubuntu using wubi is better to refer to Wubi group...

You've created dynamic drives under Windows. If you look at the fdisk output (which uses the MBR partition table) it can only see 4 partitions and they're all marked SFS.
BLKID doesn't seem to have a problem identifying them... but it uses a different technique than fdisk.

I'd say it's extremely dangerous to be running an OS that isn't aware of the underlying partitions. It works because the partition containing Wubi exists (that's visible to you under /host) and it can see the others that correspond to a physical partition in the MBR partition table, but it's not aware of the dynamic partitions on top of these.

So I'd stop using Wubi, and consider getting rid of dynamic partitions and instead create an extended partition and mutliple logical partitions within that. This is visible from both Windows and Linxu. Dynamic volumes are (as far as I know) entirely a Windows construct (proprietary) and don't play well with other OSes.
Alternatively maybe LVM can be seen by both Windows and Linux.

Hope that helps.
