Select each MS Data entry and use "P: List files". Do not use left/right arrows at all. Only use up/down arrow keys to navigate partitions and look for files. For each partition that has familiar files, not down start/end/size and continue to the next MS Data partition till you have looked at all MS data entries.

Did you look at the other thread/discussion where Testdisk and Gdisk are used with the steps to recreate the GPT and check each entry? If not, please take a look.
This looks like the best candidate

i dont know wt to do up to this step..
After 'd' and '4' do a 'w' for write, and then 'y' to confirm it has been deleted. Use 'p' to print and check that there is no GPT 4.
It still has partition 4 in memory, so you cannot pick an overlapping first sector.
Thanks,
then i should type in 196718600 for the first sector and 343476224 for the last?
am i correct?
