Trying to format an old HDD to put in another computer. But i keep getting the error like.. "cant format because programs being used by this HDD." Ive removed the HDD and my computer still boots up!! so IDK whats holding it up? it doesnt have my OS on it and it wont format! Ive tried changing the paging file through system properties and virtual memory. Still will not let me format this drive. PLUS when i try CMD DiskPart program... and type LIST DISK.. the window just closes after flashing a list thats empty. PLEASE HELP!
