Hi,

i have an alienware x17 R1 with 2TB raid 0 ssd.

i recently had a problem with my alienware were i had « no boot device found » because of some error on my ssd. In order to fix that i tried to reset my pc to factory settings but i couldn’t succed so i ended up removing raid on my ssd from the bios.

From there i tried to boot on some usb key that had windows on it but had error 0x80070057 and couldn’t remove any partition or create any. (i still had 2TO displayed on the windows recovery and on diskpart aswell at that point).

from there i used the command prompt and selected the main disk that had 2TO displayed and cleaned it with diskpart. I rebooted my pc and could install windows but now i only have 1TO displayed instead of 2TO. Only one ssd is showing no matter what software (same in the BIOS) i use and even when i try to reset my pc again.

i tried to change my ssd position to see if they had a problem (unplung one and let the other, switch their position). And it seems like both of them have 1TO with same things on it but i can’t have my 2TO back and can’t recreate the raid again.

i probably messed up by removing the raid thing in the bios and i’m getting out of ideas on how i could fix that so if anyone has a similar experience or some clues on how to fix this please help me. If you need more informations please let me know.

• the storage is still set to raid on in the bios and if i change it, i have no access to my pc.
• both ssd seems to work if i unplug the other one
• i have access to my pc
• I used every dell tool to diagnostic my pc and they find no errors

Thank you for reading and for help
