Windows 10: Secondary HDD not showing

I got HP 15ay-543tu with windows 10 ver.1909 installed in it

I istalled a new ssd with os in it to the main os boot space. And my older HDD as in DVD reader with caddy

First few days it works fine, but suddenly it stopped showing in windows explorer, disk managment, device management and even in BIOS

I don't know how it happend and even im running low on disk space

Even my older hdd is running on other pc and laptops with same caddy and other hdd with same caddy on my system but not mine

When i plug it in on SATA DVD my screen also goes balnk nd nothing shows up on it.

voice of running disk also comes but it shows no where

Help choosing a secondary HDD

I have a Samsung SSD 850 Pro 256GB SATA (love this thing) as a boot drive and a 1TB Toshiba HDD for storage and every thing else. I need a bigger secondary HDD. Is there an advantage to a hybrid drive like the Seagate FireCuda as a secondary drive? Any suggestions?

Thanks in advance.

 

Secondary HDD showing up under "Safely remove hardware and eject media"

Windows 10 Home 64 bit. Asus P8Z77-V mobo. Intel i7 3770K cpu. Primary SSD 500GB 850 Evo. Secondary HDD 500GB Seagate 7200RPM.

I went into the mobo bios and tried to fix this. When I went into the SATA settings the secondary HDD wasn't even listed there. And the "hot plug" functionality was already disabled for everything. I'm not sure what the deal is with that. I'd prefer not
to have to go into the registry and mess with things.

Secondary HDD not found by Optimize and Defrag

Hello,

Upgraded to Win10 a few weeks ago. I have a 240G primary SSD (C and 1TB internal secondary HDD (E, plus a 1TB external USB backup drive (J. I wanted to determine why the internal 1TB HDD seems to have some 'missing' space so I opened Optimize Drives.
But Optimize Drives only lists the SSD (C, USB drive (J and a System Reserved drive. It doesn't list the internal 1TB HDD.

So far my searches have turned up problems where extra drives aren't recognized at all, but mine works fine for everything else (I've moved Libraries there, created system images there, it shows in Explorer, etc.)

Edit: Device Manager indicates no issues with the drive. I've also right-clicked from Explorer > Properties > Tools > Optimize, and the list is still missing this drive.

Can anyone explain this or provide a solution?

Thank you!
