[SOLVED] My HDD is not working after changing mobo.

[whiter0se]

So i have upgraded my motherboard to MSI A320M A-PRO and ever since i cant use my hard disk. I was using w7 before mobo upgrade and when i've switched to this new mobo, I've installed Windows 10 but now my hard disk is not working for some reason.

I'm using hdd for storage and ssd for the OS. its being shown on BIOS but when i boot into the Windows and try to initialize the disk, it gives me this error saying: "A device which does not exist was specified" and when i try to see the hdd on Diskpart, its shown as disk 0 and 0 mb of size.

but there's this weird thing happening when i try to switch from AHCI mode to RAID; my hard disk is being shown with its name and actual size without any problem. and of course i can't boot into Windows with RAID mode on XD it says "insert proper boot device". So as u see my problem is very confusing and idk what to do, please help.

You have made a lot of changes and need to go back and start over.

Try the following:

Read first, plan out the upgrade, have everything you need ready.

Go slow and carefully.

Skip RAID - if there is not a specific need for RAID then do not use it.

Also: do ensure that all data is backed up and proven to be recoverable and readable.
