I have a case Qnap 4 drives , (customer says Raid5)
3TBx4 Drives (Says there is 9 TB capacity)
Axcidentaly resetted and writed some data over on it after reset.
Its working good. But new data around 500 gb after reset.
I have cloned all 4 disks to 4TBx4 drives
%100 and there were no bad sector.
They don't allow to use Qnap device.
I have never worked on Raid and Nas.
Chcked drives in Hex
1 and 2nd drive look same
3 and 4th drives look same
Data look not encrypted.
He need whatever we recover in this drive. So it was working automaticaly backing up day bay day, New data comes after 6 days period. They could see 6 days data before reset
Tried with Rstudio, UFS DMDE. But couldnt go far. I could find some small files . But couldnt rebuild as in Qnap device.
Its Urgent case. Could be remoote support if anyone wana help
I need advices
