I need help with testdisk.
I've had two 2000 gb disks mounted in a NAS mode RAID Filesystem: ext4
One day there appeared a NTFS partition on both disks. The ext4 Partition was not accessible anymore.
I tried testdisk deeper search. Test disk does not find any ext4 partitions just several hsf+ besides the NTFS one. Unfortunately i do not have the log of the deeper search anymore. One search routine lasts 2 days. I ca do a new one if it helps.
Testdisk can not access the HSF+ partiotions for file listing.
I now tried to restore the mbr but testdisk was not able to do it. This operation also took 2 days. Please find the Log attached.
can anybody help me how I can recover the partition? I also tried photorec, but recovering the stored 1,5 tb would last 200h and the whole folder structure is gone. I am very despered at the moment
