GPT Partition Inaccessible

#1 Post by walter » 06 Dec 2018, 01:42

Good, I write with the hope of help, I have 2 discs on my pc and the largest of three teras was corrupted I do not know why, this is divided into three partitions, call 1, 2, 3, get back the 2 and the 3 which I intend to endorse the other disk but scandisk refuses to recover the 1 claiming that the file table is corrupt, I have dealt with other programs but I could not, if I try to access it, it tells me to format it, it has a tera that partition, I can not find the way to recover it and I do not know if there are other more powerful tools, I have used MiniTool Partition lite, partition magic, the hiren I have not tried yet another one called EaseUS, you can help me ... thanks

I attached what to testdisk took more than three days to perform, I am wrong with the record, it is 3 Teras but it comes out as a much smaller one.
Should I give partition 1 for lost?
Something else that can be done to recover that partition
Thanks in advance

Run TestDisk, Advanced, select the partition "2" (your first NTFS partition), Boot, RebuildBS, List.
If you can see your files, choose Write, confirm, Quit and restart your computer.
Please post the testdisk.log file content if it doesn't work.
