(Personally I usually perform these tests 2-3 times, test some drives even for a week in 24/7 mode, just to confirm that they are *really* perfect before putting any kind of sensitive data on them).Īs the repeated test showed absolutely no slowness, no darker blocks - and also the other tests also passed, I'd be comfortable to use the drive. Personally I'd do exactly what you did: repeat the test, just to verify if I see the same problem, the same areas slower - or not. I mean that if some operations used on a difference device which may shared the bandwidth (for example a different USB drive if this one also connected on the USB line) then the bandwidth may be shared between the devices and this may caused that some areas seemed slower during the test. I suspect the generic slowness may be caused by some other activity of the system which may affected the performance indirectly, without accessing this particular hard disk. As the drive was unmounted during the test, it is not accessed by the OS (or any other software running) so they should not cause troubles in the measuring of the performance. > drive at any point, so it shouldn't be affecting testing speed, correct? > If the drive was unmounted during testing, that should mean that the computer isn't accessing the 1.) What does the first Reinitialize disk surface test result mean?
