I just finished upgrading to Windows 10 from Windows 7 by installing a new SSD as the primary disk and was planning to use the previous primary HHD as a third HHD for data storage. This PC also has had a third TB HDD that contains my music library. My initial plan was to set up the new storage config with the SSD as primary, the TB music drive as a second drive, and the previous W7 drive as the third drive for storage/file transfer so I daisy chained them in that order on the power cable. Before connecting D2 and D3 I booted the new SSD with W10 alone to check the install and was all good. After connecting D2 and D3 the machine wanted to boot to W7. I expected Windows 10 to rename the slave drives. ?? Long story short, after trying adding drives one at a time and changing the order I am at the following place: Win10 boots fine with the previous primary drive now renamed G: but the TB drive throws off this 3rd Slave Hard Disk error and Win10 does not see it. Ironically, this disk is newest in the PC and has not been used all that much since I made network changes about a year ago and can't use the network to play music through the house currently. I do use the disk to play music in the room where it resides and it worked perfectly just before the install. Does this seem like a HDD failure or have I missed doing something? Thanks for your thoughts.
