I have accidentally deleted a folder with approx. 10GB of data, it didn't really finished the entire removing process as it had been running extremely slow. I cancelled the process after it has running like 10min, but I can clearly see from the status bar that it didn't really do anything. The folder has gone though
Late on I've found out that disk# 1 is dead, and disk#2 with massive of bad sectors, so I cloned disk# 2 to another good HDD and use it to rebuild the RAID system with disk# 3 in R-Studio. Apparently it doesn't work due to unsupported file system issue (I guess). I have tried UFS explorer too, without avail
I then plug this 2 HDDs back to Thecus box and yes I see all data without problem, but not the one I have deleted accidentally .
