Hi, i've been having a problem with my hard drive, i have 3 hard drives. 1 is a SSD which has no issues, i then have 2, 1 TB HDD's , currently have both connected but only use 1. My main hdd is the one i have issues with. sometimes i start up my pc and it says its not connected etc etc, usually i would restart my pc a few times and it will find it and my pc will run fine, other times my pc starts up fine like i has for the past 3 weeks with no issues but suddenly back to the same problem i keep restarting unplugging etc and still nothing. i have 3 Sata cables and they all work for my SSD no problem so im not sure wether i should bother trying new ones? i did have the HDD's given to me 1 i think was new as i had to format etc but the one i have problems with has been used but im unsure of how much use it as had. hopeufully someone can help me because this hdd is driving me crazy!
