It’s never fun when a hard drive dies, but Synology at least makes it pretty easy to replace a dead drive in your NAS. You can get back up and running without much fuss. Here’s how to do it.
RELATED: What to Do When Your Hard Drive Fails
If you’re in this current situation, hopefully you’re running a RAID setup so that you didn’t lose any data.
If so, that’s one less thing to worry about. Plus, RAID lets you keep your NAS up and running like normal even if one of the hard drives dies, so there’s no rush to replace the drive right away. That said, you do lose some (or all) of your fault tolerance until you can replace the failed hard drive. Replacing it sooner rather than later is ideal.Step One: Identify the Failed Drive
When a hard drive fails, Synology lets you know about it by loudly beeping at you. On top of that, you’ll get warnings about a “degraded” volume.
You can see which hard drive ended up failing by logging into DiskStation Manager and clicking the main menu button in the top-left corner.
Next, open up the “Storage Manager” app.
Then, in the left-hand sidebar, click “HDD/SDD” to show a list of the hard drives and their status.
Next to each drive, you’ll see a green or red status, depending on the state of the drive. When everything is functioning properly, you’ll see “Normal” shown in green next to each drive. But a failed hard drive will display a red “Crashed” or “Failed” status. In my case, the failing hard drive was showing up as “Normal”, but it was buzzing loudly, which is a good sign of a faulty drive in the making.
The disk number will be the drive’s position in the NAS enclosure from left to right. So if “Disk 2” failed, then it’s the second hard drive from the left.
Step Two: Remove and Replace
After determining which hard drive went kaput, you can remove it from the NAS enclosure. You may have to completely shut down your NAS first before removing a hard drive, but most Synology NAS boxes support hot-swapping. In that case, you can leave it powered on and remove and insert hard drives all day long without an issue.
