How to recover data after repartitioning a disk?

Question

Hard disks

Good day.
Today I bought myself an SSD drive, installed a system on it, partially software, and decided to merge partitions on old disks.
I did it all through the Minitool Partition Wizard. I
repartitioned, read all the pop-up windows, after I made sure that there were no warnings about a possible loss of data, I started partitioning.
I marked it, I go to "This Computer" and I observe blank disks that were occupied with information before re-partitioning.
Please tell me how it happened and is it possible to roll everything back?

Answer 1

With simple formatting, you don't need to restore the "info", at first it's easier to restore the previous markup, because it's much faster, even a quick scan of deleted files.
And for this there are Akronis and Paragon.

Answer 2

You formatted an old disk. That is, you have 1 old disk, it had several partitions. You demolished them and returned the disk to the 1st partition. It is necessary to restore the information most likely already with programs for recovery. For example, the most popular Recuva, R-studio. Restore necessarily on ANOTHER disk !!!!!!!!!
