     Do you see a message that says WDCTL_RST failed?  If so, then
this a known problem and there are already multiple PRs for it.
If not, then you need to provide more information, such as a dmesg
(at least a snippet showing the hard drive part) of when it fails
and when it succeeds.  As is, you haven't provided enough information
to even have any idea what the problem is, much less diagnose and
repair it.
