So I bought a TOSHIBA X300 HDWE140XZSTA 4TB 7200 RPM Hard Drive from Newegg then I proceed to plug it up and all was good. It was displaying in bios info then I decided to install windows 10 onto my SSD. Loading windows 10 I decided to go ahead and format the 4tb there, it formatted successfully. Then I proceeded and installed windows 10 on my SSD. After installation my drive was missing wouldn't display. Restarted PC same issue, restarted went into bios remembered something about AHCI, changed my sata port mode from native IDE to AHCI this was after the windows 10 install, shortly after my Toshiba x300 disappeared from the bios/windows 10 installation screen, I couldn't get it back. I went into my case re connected sata cables and sata power cable, tried different sata cables and sata power cables none worked. It eventually came back last night as detected. I wiped sweat off my face and thought to myself good days work. Was just a bit happy to see the drive being detected any at all. I went to sleep woke up, lo and behold drive no longer in bios, tried to reconnect sata/power cables tried to clear bios tried near damn everything. Drive won't get detected. It gets hot as if it's in use but it just won't get detected. Is this drive dead?
