I have a Toshiba satellite A-200 laptop with a Vista OS on it with 4 NTFS partitions
(C:) Vista (D:) Entertainment (E:) Work (F:) Sources
and I wanted to start using Ubuntu instead. So I tried it first from the live CD and everything was OK and all the partitions were shown and working and so I decided to install Ubuntu to replace Vista on the (C:) drive. After I did that I can no longer find my folders and files on the (D:), (E:), (F:) partitions and the only file system that is shown is one 198 GB although my HDD is 320 GB.
I can't access the lost data on the remaining 120 GB which I hope is still there and not totally lost
I am now working from the live CD but I am unable to install testdisk. Can I recover the Vista partitions by the product recovery CD to get my laptop back to the factory settings? Can I recover the NTFS partitions using a recovery program for Windows or will that make the problem worse?
I need these data badly as I don't have a backup for them.
