In this photo you should see 4 Discs. Only 3 are recognized. Besides the 60 Gb SSD (B & C) and the 1 Tb HDD (D) there is another 1 Tb sata2 HDD attached also, but is not displayed for whatever reason... HD Tune shows the HDD, but no letter is assigned to it. A month ago there were no problems and the HDD would quickly appear in My Computer. I am dull founded. I inserted another drive - another SSD instead of HDD - same result. I changed AHCI to IDE - nothing. I formatted the HDD in Windows setup to NTFS - same nothing. Obviously it is not a hardware problem as both the SSD and HDD are independently not recognized, something is messed up with Windows, i have no clue what!!! Windows search is enabled.
