i've been wondering why my computer does this, but i got a new SeaGate HDD (2TB) and it's properly attached and all, but it still keeps unmounting itself.
there are a few files i put on there (movies, music, etc) and it works just fine. now, whenever i want to install a game to it (D: drive btw) or clean it/degrag. or do ANYTHIng with it, it, it unmounts and no longer appears in my list of storages. the only way to mount it again is to re-boot the computer. It's probably a bad sata cable/connection, but i need still need advice.
