Where is the support page and user manual for this enclosure? How do you check the status of the RAID array? How do you check the status of the disks? How do you check the status of the rebuilding of the RAID array? What do the LED's tell us? What do the beeps mean? There's no support for this device.

The user manual has absolutely no troubleshooting information.

Also, what is large mode?

Large mode is one of the RAID modes supported by the MAIWO 4 Bay RAID Enclosure, alongside modes like RAID 0, 1, 3, 5, 10, Clone, and Normal.

New, not even 90 days old. RAID 5 setup and working fine. Random beep heard and now all of my files and folders are gone. Enclosure shows 3 of 4 drive LED's lit, I assume indicating an issue with 1 drive. WHERE ARE MY FILES?

Please contact MAIWO Customer Service, they will offer you a replacement or refund.

Brand new purchase, less than 90 days old. Unit beeped and only 3 of 4 LEDs for Drives lit. RAID 5. OS shows no files or folders on the logical disk????

New disk needs to format or repartition first

2 drives inserted, only one drive shows up. And it beeps non-stop? There is no documentation about the beeping.

first set your desired raid mode,then press"reset" for 3 seconds. Before operation please backup the date in your disk.

I have two of these, When I try to set it up all it does is beep. I have tried resetting the mode to normal first as directed. Documentation is awful and there is no support number ?

Set your wanted raid mode first, then press"reset" for 3 sconds, please contact our customer service, they will help you further.

how do you use the HDMI port by app ?

The HDMI port works as a passthrough from the USB-C connection from your source PC.
