MHDD can't find any disk after 5 years of successful servic

[RPT]

I have been using UBCD (Ultimate Boot CD) bootable from USB drive for many years.
MHDD 4.5 or 4.6 on the same test PC for 3 years, but today MHDD reports "no disks are found".

If using Disk wipe from same bootable UBCD, disk is initialized normally and there is no problem.
Windows is also capable to boot from any HDD but MHDD fails.
There is no other SATA devices just single drive for test attached.
In Bios disks are recognized normally and are set to legacy option.

Any ideas, what might have been happened to PC or UBCD?

Seems that problem solved - something wrong with mobo BIOS and SATA port interaction.
