Hi,

My 3-drive RAID5 array has been working fine until receiving that error yesterday; I can no longer access the drive. Everything looks normal, however in RAID Manager, and under Disk Management in Windows 10, it says 18627.92 GB RAW Healthy (Basic Data Partition).

What is the safest method on attempting to retrieve the data?

Thanks.

From the situation you described, it seems to be a serious damage, and the file system is no longer recognizable.
Perhaps you can only try data recovery software or seek help from a data recovery company.

When you are using a disk array, before you press the power button to shut down the device, every time you need to safely eject the USB device from the computer, or the file system may be at risk to be crashing.

Thanks, I'm running chkdsk /r <drive letter> right now. Fingers crossed...

I was able to fix it with the above command. Took about a day, though.
