Your screen only displays unrecoverable partition.
If you confirm with enter, you'll get to the results.
I'd need a screenshot from Analyse and Deeper Search.
You can stop Quick Search to save time.
The results are important.
Did you use testdisk 64bit?
In case you should use the 32bit-version instead and select Disk instead of physically drive.
A 4 TB disk scan can take time.
If you think your right partition is found and displayed (for example has its label), you can press enter to stop the scan.
Mark that partition and press p to have a try to list your files.
What kind of partition table type uses testdisk?
Intel or EFI GPT.
TestDisk finds it automatically.
Your partition type is FAT32 LBA.
Please explain what did you mean "while alignment"?

Also you can open the file testdisk.log using a wordprocessor like wordpad and copy and paste the content into your next post.

here is Deeper Search results
I get 3 partition all invalid
I choose fat32 lba one
but says cant be recovered
and
Im getting 'no partition found or selected recovery' msg
then I get partition read error all other actions

my hdd was MBR base 4tb primary fat32 partition(not gbt...its speacialty for seagate backupplus )
I was using Paragon Alignment Tool 4.0 Professional for aligment ,inthe middle power-loss

Im trying open log but too big..I will delete the log and start scan with clear one

Would it be possible to use the 32bit version?

Does paragon supports "advanced format" ?
Intel MBR only supports partitions up to 2.2 TB.
Why did you try to align a partition?
Was your disk before working?

As far as I've seen, Deeper Search didn't find your previous partition either.

no I didnt do any format by paragon
its about seagate backup plus hdd case
it let you format MBR fat32 beyond 2.2tb
but if take out of the case and connect direct sata to pc...hdd shows unformated

aligment was my little bro's stupid action...he tought hdd will be faster
it was working perfect before and Im sure it will work perfect if I create a new partition..
but need my old partition and folders back

Until yet, testdisk didn't find any fat32 lba-partition, which would fit to your disk.
Would you be able to create a fat32-partition which would fit exactly like your previous partition?
But don't format it.
Otherwise you'd override your underlying partition.
In this case, you'd be able to diagnose a boot sector and maybe to recover your partition?
If you create an unformatted partition, it would be only written to your partition table in your MBR.
So it doesn't touch any data within your partition which starts by a boot sector.
Otherwise you'd need datarecovery software.

Please let me know.
