3 drives showing failed after repalcing bad drive. WD Sharespace

ok looking for some help here as I have replaced a bad drive (#4) with a brand new one and since I have booted up the unit again the 3 drives that were still working and showing data prior to the reboot are now showing as failed.

this unit is running raid 5.

Did you insert all hard drives in their original slots? Did you replace the faulty unit with a certified (Compatible) hard drive unit, or did you use a different one?

never removed the other 3 drives and replaced with the exact same WD Drive.

is there a way to console in and force a remount of the raid so I don’t lose my Data as the whole point of a raid 5 is prevent this type of data loss due to a single drive fail.
