Windows 10 TP Hiding Hard Drives?

Anyone having trouble with Build 10041 hiding Drives?

Yes. I have a iomega USB 3 drive that windows 10 can't recognize (works on 7, OSX and Arch on the same hardware).

Can anyone use USB attached SCSI in 10? - Windows 10 Forums

Oddly enough, this has to do with my post of a couple days ago, only thing is, it's getting worse!
These are SATA drives that have always been in there.
Thing is though, Build 10041 has never been able to 'find' or install SATA Controller driver, all drives are treated as 'removable'.

I assume you mean it's some third party SATA controller? A Plug-in card?

When the drives are treated as removable, it means two things:

1. You're using AHCI and
2. Your drives are set to "Hot Swappable".

When they're hot swap, it means you can "eject" them, and thus they're treated as removable, even though they're "fixed disk". Many SATA controllers have Hot Swap capabilities.

Nvidia Controller has always been natively supported until Build 10041!?
However, I don't know if it has anything to do with the drives disappearing.

In my case the problem is the MS eXtensible Host Controller driver. The Intel one (in windows 7) works but since Windows 8 Intel don't develop this driver and the MS one doesn't work. I could install the Intel one on 8 but not on 10 (well I can install it but it doesn't work).

They do seem to be updating it though - in 9926 my hard drive failed to work as UAS. Now it fails to work as a virtual SCSI CD drive (for some reason) which is at least a change if not particularly an improvement.

Darn, wish you wouldn't ask questions like that. Here I went looking for my HDDs and couldn't fine any, . . .then I remembered I didn't use HDDs only SDDs. . . . . .sorry had to throw that out there. Just got back home yesterday form the Hospital (Another mini-stroke) and when reading the question it did cause some bite of confusion. . .

you might need to click on the refresh icon, then - if the drive shows up..
right-click on the drive in Disk Management and allocate a letter..
- it should then show up in the "This PC" listing..

PS - look for the HDD/SSD in the lower portion of the interface, it'll be one of those with no drive letter allocated..

I run SSD's for my OS partitions too (hope you feel better Lee) but even though all my Control Panel> Power> settings for sleep, hibernate, etc, everything has All Been Set To Never, but I'll notice after about 5 minutes that I can hear my TB spinner I use only for Storage spin itself down, and notice it'll only start when I go access something that's located on it. It's connected right to the MB SATA 6.0 gb/s ports not usb of course. Doesn't do that on Win7 or 8.
I'll figure it out when necessary, no big deal right now since I know it's something simple, but saw this thread and reminded me of it so I mentioned it as a fwiw, and I never noticed the previous 10 build did this - I don't think so either. I'm running an Intel Desktop Board DZ77BH-55K
