Hard Drive now RAW format on a Storage Spaces pool drive. Happened during Reboot.

Thanks in advance.

I recently upgraded my storage spaces and increased my storage size. I added an 18tb drive to an existing storage space. During this process I increased my storage space size (logical) to 80TB. I have 5X 18tb hard drives. The drives are set to parity, since the information on the hard drives are valuable to me.

I was able to use the additional space and load it with files. I then rebooted the computer. The computer had a new USB drive attached to it as well. (during the reboot)

After rebooting the PC, the entire 60TB drive was set to RAW instead of NTSF. I am currently running a CMD CHKSDK to repair it. (1.5 days in).The CMD prompt reads the drive as NTSF. I am able to see it in windows, but it no longer has the drive name. Just E:. It is named properly in CMD CHKSDK.

I SUSPECT i made the drive too big logically? Is there a way to fix this ? I desperately want the data, but don't know how to proceed. The only option I get is to format the drive.

  1. Is there a way to slowly take the data off that drive?
  2. Is there a way to fix this in windows?
