2x hdd mediasonic raid1 shows raw data

#1 Post by throwaway88 »

I have a mediasonic 2-bay raid enclosure with 2 6TB harddrives inside that are GPT and RAID 1. Windows detects the RAID and individual disks as raw data. I tried running Testdisk and the partition seems fine but shows MS Data. Structure shows Ok and the partition is there.

How do I get Windows to read these harddrives again? I went to T: change type, but then I'm not sure what options to choose as there's about 30 different choices. First option is MS data, after selecting that it shows NTFS. Should I just hit the write button? How do I fix this issue?

Why "but MS Data"?
Structure shows Ok and the partition is there.
Use the "p"-key to list files inside the partion. There is a reason your windows is unable to read it. What is the file system used?

Unreadable drives rarely get readable but changing the partition type. "MS Data" is good. By selecting NTFS you would enforce MBR and therefore change the partition table type. That won't solve your problem and could create new ones.
