External harddisks not recognized when switching on the harddisks 1 to 12 seconds after the PC, OK otherwise....
Attached to my Asus PC (running Win 8.1) is an USB case holding 4 hard disks (JBOD).
When I switch on the harddisks first, and then the PC, the hard disks are recognized.
When I switch on the PC first and the hard disks later, the hard disks are not seen (even when waiting for hours) - unless I wait for about 12 seconds to switch on the disks, then they are seen.
What does cause this behavior, is it a BIOS issue?

What happens when you just disconnect and reconnect the USB cable?

What are you saying? That, if you boot your computer at 1:00:00, the hard disks are recognized if you turn them on before 1:00:00 or after 1:00:12, but not between 1:00:00 and 1:00:12?

@Scott, yes, exactly. If they are already turned on when the PC is switched on, the case's disk access LEDs are beginning to blink quite quickly, a matter of maybe 2 seconds. The PC is a fast Intel i7. If the case is turned on about 12 seconds after the PC, the LEDs begin to flash quite immediately. Turning it on anywhere between 1 and less than these 12 seconds: no hard disks available, no matter how long I wait.

4 disk USB raids are always slow to start - What you are experiencing is normal.
No, what I mean is this: the hard disks will never be recognized, when they are switched on within the 12 seconds time window. I can wait for hours, they won't be seen. - Also, they are not organized as a RAID, but are simply JBOD.
