[hard disk failure] Partitions size incorrect

[soundlord]

I let my enclosure fall yesterday and now this 3To drive is messed up :{
If I remember right there were 3 partitions in btrfs and now they are displayed as fdisk -l tells: 128Go 83 Linux, 128Go 83 Linux and 100Go HPFS/NTFS/exFat...

I never took a picture of the partitions so I can't remember the start/end of each partitions :{

I got lot of works saved on this drive and I would try to recover the most of the datas but I don't know how to proceed...

[soundlord]

I tried testdisk but it seems all the filesystems are damaged... and this application looks inappropriated
Using btrfs check on all the supposed Btrfs partitions seems to do nothing... except output "No valid btrfs found on /sde1 etc..."

I did a mistake using mke2fs... I used -v instead of -n... on /dev/sde1

It seems the sizes of the three partitions given by "fdisk -l" indicates the room left of each partition before this hard disk fall... (offline from 60 cm)

When the unexpected happens I need to recover from backups: There Is No Such Thing As Back-Up Overkill!

I use to but this time it was VERY unexpected ^^

I'm using Recovery Explorer Standard... 19 hours to scan the whole disk... hope it will find some files ^^

Each partitions were initialy about 1 To.
It seems that the size of each partitions here are corresponding to the room left (approximatively) on each partitions.

Why don't you include the line with the command when you copy/paste from the terminal in between the CODE tags. It is only one line, not much of an effort isn't it? Now we have some output but we do not know why it is there!

This seems so difficult to understand for many that I will give an example. Not

5.3.18-150300.59.63-default

but

henk@boven:~> uname -r
5.3.18-150300.59.63-default

When that what is posted in post #6 above is the output of some fdisk command, it looks like an DOS partitioned mass storage device of 2.7 TiB, having three partitions, that follow each other without holes, of 128G, 128G and 93.3G.
Together ~349.3 G. So the rest is unpartitioned. Looks not abnormal at all.

Sorry for the lazy caracter of the output...

Yes I did a fdisk -l, and for now... testdisk recovered a partition (600 Go) at least.
I think if I go deeper I would recover the whole harddisk... with some losses undoubtabily...

I have now two usb devices moving datas at a 30 Mb/s speed :{ it will take hours to move the datas.

Once done... I will try again on the partitions detected by testdisk and try a deep search on the first partition that contained the "most important" datas as well as the one currently backed up.
The third partition contained some movies I think... it is not very important if I loose the partition.

These datas returned after testdisk wrote the partition table is more accurate with the reality before the external disk fall.

You better stop acting in panic. That will not help you with any recovery.

Now you used QUOTE tags instead of CODE tags.
