DX4000 HDD issue

Dear all,
I have problem with Sentinel DX4000, he sometimes reposts wrong HDD (everytime the same place - even with new HDD), when I put out the HDD and then put it back, it works and start recovering…any idea why Sentinel is doing this?

Thank you in advance

If you still have the old hard drive I would try to slave it in a windows pc and run a S.M.A.R.T. test on it. Something like crystallmark. If it does not report bad then it may be the connectors in the box. If it does show bad then the new drive may be questionable.

wrong hard drive or bad/missing?
You might try that new drive enabler download if it says wrong
