I changed the computer and try to use my old 200 Seagate IDE NTFS at the new vista computer. When I connected the IDE disk, I saw it at Bios and also at the computer management in dynamic form.
Unfortunately, I converted the dynamic disk to basic disk w/o back up.

Now disk wants to be formated when I try to acces from "My computer" in every computer I connect to.

Is there a way to recover data.
would you please be specific more that saying try this software, maybe it helps.

I am sure someone has faced this problem and I would like to hear if there is an exact solution..
Thank you in advance for all..
