Windows 10: Why does Win10 not recognize2 of my disk drives?

My system has 4 disk drives: 128GB SSD boot drive, 500 GB HDD data drive, 1 TB HDD data drive, and a 64GB SSD work/temp drive. This is how it looks in Win7:





X: is the SSD where I have placed My Documents and Temp files.

To boot Wini10 I replaced my C: drive with a new 128GB SSD and did a clean install of Win10 on it. I had 2 immediate problems: I could not activate Win10, and Win10 did not see 2 of my disk drives. With the help of someone here I was able to get my Win10 activated, but the system still will not see 2 of my drives. Here is what Win10 looks like:





As you can see, Win10 sees all 4 drives, but for some reason it says D: is not accessible, and it does not give Disk3 (what is my X: in Win7) a drive letter - so it is inaccessible too.

Needless to say all drives work fine under Win7, so it is not clear to me what the problem might be.

Another peculiar issue is that when I switch boot drives and go back to booting from Win7 the system goes through a complete CHKDSK on all 3 of my non-boot drives. This sugggests that WIn10 is doing something to the drives that Win7 does not like. I'm a bit reluctant to keep switching between 7 & 10 because I'm concerned that I might lose a drive if the CHKDSK function fouls up or has some sort of problem.

USB Connection showing "Fixed Disk" rather than "Removable Disk"

I re-installed Win10, and connected my GPS via USB, and the Win10 OS still categorizes the device as a "Local Fixed Disk". When connected to my Surface Pro3 running Win10, the GPS is categorized as a "Removable Device".

I then used the suggestions in Method 1 and Method 2, and the device drivers were installed in compatibility mode (Win7). Again, the Win10 environment sees the USB GPS device as a "Local Fixed Disc" rather than a "Removable Disk".

Why is it that my Win10 Surface Pro3 coming from Win8 sees the USB device as a removable disk and my Win10 desktop PC coming from Win7 defines it as a local fixed disk? I don't believe this is a Garmin problem.

 

System reserved is created on non-system drive

Hi, I installed Win10 on my HDD (C (that's Disk 0 in Disk Management) but the System Reserved partition is on my other Disk 1 (picture bellow). When I ran installation I selected this HDD as the one where Win10 should be installed but still SR is on the
other disk.

How can I move System Reserved to Disk 0 and merge partitions in Disk 1? Also why did Win10 put System Reserved to a disk which is not bootable?
