Finally!The Win instalation interface from the usb win 10 boot media recognized the HDD and allowed to format the partitions from that drive among which was a recovery partion.That recovery partition, probably, prevented the new installed OS on the SSD to recognize the HDD, because from the 4 partition existing on the HDD, only after I formated that particular one, the new OS recognized the HDD. I tried after each action of formatting one of the partitions to see if somethings changed and only from that point the HDD appeared. So, if somebody else faces the same problem, consider this way of solving the issue and it will, probably, spare many hours of your time. Probably! Thank you, Vic384, for you time and support! Have a nice life!
Hello! On my XPS One 2720, my original 32 GB Samsung msata cache SSD crushed a few months ago, and I replaced it just now, with a 250 GB Samsung 860 Evo msata SSD, and I installed on this one, first the Win 8.1, and then, upgraded to Win 10, without deleting the other 2 TB HDD, that had the initial Win 10 installed on it. From the first installation, the BIOS recognized the original HDD as SATA 1, with all its atributes, name and size, but the Win 8.1 did not, and the same was the situation with Win 10. The SATA mode is in AHCI, and I changed it like this before Win 8.1 installation, and there is also a ATA option listed. When prompted to install the Win 8.1, from a Dell boot media, there was no option to install on the original HDD and the Disk 0 was the new msata SSD. The Win 10 works well, from the msata SSD, but I can not use the HDD due to not being recognized after Windows is loaded. The system first boot is Window managed. How can I regain use of the 2 TB HDD, as a storage drive? Thank you!
