|TestDisk did not detect bad HDD.|
My OS is Windows 7. ASUS M4A785-M MB, 1 Seagate external HDD and 2 Seagate internal HDDs. Use 1 for OS and program files and 2nd for files, photos, and all documents.
2nd HDD is not detected in boot process or disk management. It does not show in BIOS either. It's as though it does not exist. Since the disappearance of 2nd HDD, boot process seems to be slower than normal. Have tried "seagate tools" and other things; including TestDisk. Nothing seems to recognize the 2nd HDD.
