Hi , i have a asustor 7010 with 6 x 8 TB under RAID 5 , but now the drive 6 failed and become incessible .

You can replace the bad disk with a new disk with size >= the original size.

However, it's abnormal for volume size = 0 and free space = 0. Normally you can still access data without problems even if one disk failed (RAID-5). Where did you see the information? You may post the picture here. And did you run out of volume space?

1) did a bad block scan of 6 of the HDD and only the nos 6 HDD have bad block.
2) inserted the same size and same brand seagate new hdd to tray 6 but the Asustor did not rebuild the drive?
3) Yes , aday before it failed bal space is around 600GB free space and start to delete many unused video files ,but during that time it hang and after restart , only can login and see the folder still there but not able to go in to read any files.
4) Now the Vol 1 show total space=Zero and free=Zero

There should be more failures in your volume. Your volume shows "inaccessible" which means not in degrade mode. Normally RAID-5 volume will show inaccessible status when 2 or more disk failures. But you said only one failed disk... It could be one disk failure plus some others. Not sure what's the problem without detailed logs. I think you should send a support request to asustor directly. https://support.asustor.com/
