I've been struggling for quite a while now with a two year old Vantec NexStar HX4 4drive enclosure.
I'm using its USB 3 interface on an "House Brand" i5 Intel tower system (16gb ram) that also includes 2, 2TB internal HDDs, a 2TB WD Passport external HDD and a USB printer.
The drive bay worked fine initially, probably with less of a load back then, but then started to fail to "hook up" the HX4 drives. I first had it populated with three 1T Seagate 7200rpm drives and one 500gb Seagate.
It would cycle through several rounds of lighting up the drive indicators (in order, top down) then they'd all shut off... then start up again and cycle through the powering up... many times. Sometimes it would settle down... mostly I'd just turn it off, unplug the USB connection, reboot and start over. Hit or miss success. After long sessions of run time, shutting down the PC would often leave the HX4 drives still spinning instead of shutting down, as it is supposed to do.
I've recently updated the HX4 by changing out the 1TB drives with 2TB Toshibas and keeping one 1TB Seagate. I was hoping that this might make the HX4 happy. Not so much. At best it will see 3 out of 4 drives. I've checked the drives for viability, one at a time, and they are easily mounted by the controller.
I'm thinking, for no particular reason, that my base machine is unable to manage all the USB load that I'm asking it to carry... but am at a loss as to how to prove it or whip it into shape. That or this particular drive bay is less than up to the task of managing this load.
Before I fix the problem by replacing the base system I thought I'd lay this out for the pros to comment. Any insights are appreciated.
FWIW, I record and edit live music. I've been doing it basically 120 dates a year for the past 10 years and I have a lot of files. Without turning my hobby into an exercise in backup management and archiving to DVD, I continue to keep them handy. I do have some cloud backup started but it's not enough to cover this system entirely.
