[xuanguang]

I use another SD card which has 8.0.3 x64 system too boot my pc, and the disk (1TB,whose volume name is WD1TB) used in 8.0.2 system, but I forget to use import volume, and do wrong ----- use creat volume, name it WD1T...............and I can't see my data any more.........
I changed the old SD card which has 8.03 x86 system too boot, and it warned me that the volume status not well, I can't see any data............so I change the volume name to WD1TB,but the volume status still wrong..............
How can I do?Can I refind my data?Almost 1TB data............................:(:(:(:(:(:(:(:(

You created a new pool over top of your original pool. This destroys the old pool. Unfortunately, you have lost your original data. It is gone.
