Again, I put this down to leaving the drive running undisturbed, 24/7. That too has lasted incredibly well, with over 80,000 hours of runtime on the clock. During that time, with the exception of a power supply failure, it has never missed a beat.Īt the time of purchase, I replaced the OEM Seagate hard disk drive with a nice Western Digital 2TB Black, 7200RPM. Apart from a couple of years spent in storage, the machine has been left running literally 24/7 since it was new.


I would like to ask for some help relating to a cloning issue, which is doing my head in! But first, some short background: I have a 12-year old Dell OptiPlex 990 SFF, purchased in 2011.
