Windows 10: Can't read data from "RAID" disk on after BIOS change RAID to AHCI

Hey,

I got an old Dell Latitude laptop that I was going to update my HDD on so I removed the old drive (it was an m.2 disk in an adapter in a 2.5" slot). I plugged in my new Samsung 840 which the computer couldn't find so I changed the BIOS setting from RAID to AHCI (Raid is default on Dell..) but still no success.. I then put back the m.2 with adapter in the computer and swapped back from AHCI to RAID but now it wont recognize the HDD at all..

I tried plugging in the 2.5" adapter via an USB-adapter to a computer but nothing.. I tried plugging it in to my Desktop via SATA-cable and I can see that the adapter light turns green as its powered but I get no data.

Any ideas on what to do next or did the change from AHCI to RAID do something?
It's fine if I can't boot on it but it would be good to access the data.

RAID recovery

Heya, usually you need to set your storage configuration in BIOS to AHCI or RAID first.

Switch to RAID in BIOS and than (I only know this for Intel Systems), restart your PC.

At the beginning of the bootsequence you should see an additional screen, with a detail list of RAID drives.

It should list your drive too, if not, than it is not a RAID0 any more.

If it can boot back to your system, you should immediately backup all data you need.

The problem is RAID is a one-way process (at least for Windows).

After you got your backups, reboot and set your BIOS storage settings back to AHCI or RAID1 or whatever you wanted. Than you can format your drive and reinstall the new OS.

Hope this will help you out.

 

Converting SATA to AHCI from RAID

So I should first use Optimize Defaults, then change the registry files and then go into BIOS again and change it from RAID to AHCI?

 

Changinr Raid to AHCI

I don't have Raid! I want to change to AHCI. When I trie normally it won't boot.
