Help! o.o

I find myself in a rather perplexing predicament and would appreciate any insight you might be able to offer. My CD/DVD RW drive has seemingly vanished from existence; it is neither recognized by my BIOS nor detected by the operating system. I have already attempted to navigate through the registry to adjust the filters, but to no avail, as there were no upper or lower filters present to modify in the first place. Currently, Windows Explorer shows nothing but a floppy drive and a DVD-ROM—which is merely a placeholder for the missing RW drive. Earlier today, I took the drastic step of reinstalling Windows, yet the situation has only deteriorated. Now, the drive is entirely absent, leaving me with nothing but that persistent, useless floppy drive which continues to show up as installed despite being physically disconnected. As for the DVD-ROM, it has disappeared entirely. To clarify the strangeness of the matter: when I press the physical eject button on the drive, it functions perfectly fine—the tray opens, closes, and even accepts a disc—yet the hardware remains completely invisible to the Device Manager, Explorer, and the BIOS alike. Does anyone have any ideas as to what might be causing such a selective disappearance?
I am currently running Windows 7 Ultimate on a system equipped with 4GB of RAM, utilizing a Sony OptiArc AD-5240S DVD-ROM drive paired with an ECS 945P-A motherboard.

First, check if you can even see it in the BIOS. Do you actually know how to get into the BIOS settings?

That DVD-ROM is probably just some virtual drive from an emulation program like alcohol or Daemon Tools.

It appears I was quite clear in my previous assertion: the drive is nowhere to be found, neither within the BIOS nor recognized by the operating system. I went so far as to perform a complete reinstallation of Windows 7 Ultimate, yet even the DVD-ROM has vanished from existence. It functioned perfectly fine under the old OS, but in this new installation, there is absolutely no trace of it—not in the BIOS, not in the Device Manager, and certainly not in My Computer. How can a piece of hardware simply cease to exist after a software refresh? 😢

Just double-check that the SATA cable hasn't shaken loose, if only to cross one more thing off your list of potential culprits.

I guess I read that pretty fast 😁

Did this just happen out of nowhere, or were you messing around with something first? Is the burner SATA or ATA?

The connection is perfectly secure, seated firmly in both the motherboard and the drive, yet an oddity has emerged: the system is identifying it as a floppy disk. After I attempted to repair the ISO using a Microsoft fix, I decided—perhaps out of pure stubbornness—to disconnect it from the motherboard entirely. Upon reconnecting it, the system immediately began installing a driver... for a floppy drive, of all things. How curious is that?

It happened quite spontaneously; the connectors are SATA.

Maybe just disable the floppy drive in the BIOS and it should stop showing up

Oh, I am well aware of that, truly, haha. My actual concern lies with the CD drive... is it possible that the installation process will simply pivot back to trying to use the floppy drive once I have disabled it in the BIOS?
