A 6 year old Hitachi drive has done very well IMO. The one I purchased failed in less than 18 months.
It would be worth doing a smart check on the drive. You need to work out whether the drive has failed or whether the issue is a windows boot issue. The white screen seems odd because when windows cannot boot it is usually black. It might be worth getting the Hitachi drive checking software and testing the drive on another PC. They might do a dos bootable CD/flash program which can test the drive. Seagate do make such a utility so Hitachi might also make one.
I did have something similar myself but in my case I got what looked a little like an off white texture like canvas which displayed before the windows welcome screen. It did not stop my PC from booting. Finding something which can check the boot block to make sure it is standard and a valid windows 10 boot block as some malware can write to the boot block. You might need to do that on another PC with a booting windows. It could of damaged the partition table which would also cause the PC to not boot. See whether you can access the drive and list the files on another PC.
