Computer recognize DVD/RW drive as Local disk on win 7 32bit

[President]

System configured as RAID 1 (mirror) and works well until this day. From today DVD/RW Drive Shows Up As Hard Drive! Under conmputer mannagment all drives shows correctly. I tried everything - unninstall, tried diferent DVD/RW drive, tried assign a new letter etc. Nothing does not help to to solve. Maybe you have some ideas?

Hi, Welcome to SevenForums.

Not sure whether this will help resolve your problem but no harm in trying.

Rebuild your icon cache. That is what comes to my mind.

Create a manual System Restore point ( just in case you need to go back ) and then try this.

Hi, Jumanji!
I already tried to do that and no success.

Can you restore your system to a point where it showed alright?

I can not do it. System Restore is turned off. Unfortunately, no choice, installing Windows from scratch. Thank you, Jumanji.

That is good.

Check your motherboard manual to see which SATA ports are driven with the RAID controller.

You may have to perhaps connect your optical drive to some other port.

Keep us posted.

EDIT: Possible explanation: "Your computer’s S-ATA connection must support the ATAPI command set. Some computer motherboards have S-ATA RAID chipsets and/or a BIOS that do not support the ATAPI command set used by optical disc drives. If you are unsure, consult your motherboard manual or vendor web site for compatibility, BIOS versions and BIOS settings."
