Windows 10 Boot Takes 20+ Minutes After Adding Internal Hard Drive

[kent.linkletter]

I am running Windows 10 on an Asus Maximus VII Formula motherboard with 16GB of memory. I have a 450 SanDisk SSD with Windows installed and a 4TB Seagate ST4000DM005-2DP166 internal drive partitioned equally into drives D, E and F. I have decided to add an 8 TB Seagate ST8000DM005-2EH112 Hard drive to provide lots of space for local backups. Without the new hard drive, the system takes about 3 minutes to get through the Windows logo and white circle phase to boot. Once I add the hard drive, it goes to an average of 20 minutes to boot. This is not really acceptable. Once it boots, it seems to run just fine.

Any suggestions on what might be wrong or how I can trouble shoot this? Thanks

did you try to partition the 8 tb drive since you use a 4 tb also with so system have to check 12 tb of drive and the os ssd are you shure your board could handle a 8 tb hdd.

In the end, I believe that my motherboard is defective. It has both ASMedia and Intel SATA controllers. I have found that I cannot get it to recognize any drives on the ASMedia controllers. In addition, there is SATAEXPRESS support on both controllers and these don't seem to work on either one. I think it is time to replace the motherboard. For now, I have disabled all ports that are not actually in use and have disabled the ASMedia controller. Thanks for getting back to me.

let hope it is only the board issue oops something come to my mind check board manual if there is not a settings that disable some port if you use asmedia or in intel .
