I am not really sure how this happened, but the nas sounds like it is always writing a disk right now and nothing is in use. I accessed it the other day and wrote something to it, but that finished up as normal. Now it just keeps clicking away and beeping every 35 seconds or so. I have no idea how to diagnose it. The resource manager seems super basic and it says nothing is being written. I restarted it one time, but it just got right back into the clicking. Is there a way to reset it without rewriting all the data?

A "beep" sound indicates a system malfunction alarm, while a "click" sound suggests possible head reset/physical damage. Do not attempt to "reset" the system: The "reset" you mentioned refers to reinstalling the TOS system. In the case of physical hard drive damage, this will corrupt RAID information, making data completely unrecoverable. What you need to do now is log in to the TOS desktop, go to Storage Management > Disks > Disk Logs, and check for any records of disk disconnections.

Use the SMART tool to perform a disk check.

1. Log in to the TOS desktop.

2. Go to Control Panel > Storage Management > Hard Drives.

3. Select the target hard drive and click "SMART Check".

4. Click "Create Task", select the check type (Quick/Full) and schedule the time.

View SMART Information
In the Control Panel > Storage Management > Hard Drives list, after selecting the hard drive, its "Health Status" and key SMART attributes (such as temperature and power-on time) will be displayed on the right. Click "Details" to view the complete SMART report.

Pay attention to the following three fields:
Reallocated_Sector_Ct
Current_Pending_Sector
Raw_Read_Error_Rate / Seek_Error_Rate

Thank you. That is a step in the right direction. the clicking is that clicking it makes when it is writing a disk, i am sure you know the sound. but ya i guess the beep is bad. maybe it just keeps trying to write something and fails. i dont know. so it is saying hdd2 is abnormal. i ran a smart test on it and here are the outputs

soooo, thats what i got. do i just need a new hard drive in there? Can it run on three drives in the meantime? can i put everything into those three drives while i reformat the abnormal one? they arent that old. a year and a half maybe.

Based on the SMART information, this hard drive is at risk of failure; please replace it promptly. If you have created a TRAID array, you can replace the current hard drive with one that is 12TB or larger.

Thank you. So just to be certain here. I do have it in TRAID, so i can just turn it off and pop it out, no worries? there is no procedure i need to follow for this?

When you need to replace a failed hard drive or expand the array with a larger capacity drive, you must use the "RAID Repair" function of the TOS system to ensure data security and array integrity. Direct hot-swapping or arbitrary replacement is not supported in TRAID mode.

When a hard drive in the array fails, and TOS prompts "RAID Degradation" and beeps, you need to replace the failed drive.
