If you've connected an HDD or SSD to your ROCK's internal SATA connector, RoonOS must format it before you can store music on it. This guide shows you how to format the drive in the RoonOS Web Administration Interface.

RoonOS 3.0 brings a redesigned Web Administration Interface to ROCK installed in UEFI mode on a supported Intel NUC. A ROCK installed in legacy BIOS mode can't run RoonOS 3.0, so it stays on RoonOS 2.x with the original interface. Please see Formatting on ROCK in Legacy BIOS Mode below.

Format the Drive on RoonOS 3.0

1. Open the RoonOS Web Administration Interface.
2. Click the Storage tab.
3. Find Internal Music Storage. The drive connected to your ROCK's internal SATA connector is listed here. Until it's formatted, it shows Unavailable.

If Internal Music Storage doesn't appear on the Storage tab, your ROCK hasn't detected the drive. Please power down your ROCK and re-check the drive's SATA and power connections.

Formatting permanently erases everything on the internal music storage drive, and it can't be undone. Your Roon database and settings aren't affected.

4. Click Format.
5. In the Format Internal Storage? window, click Format to confirm.

6. Wait while the drive formats. A progress bar shows while it runs, and it can take a few minutes. Roon stops while the drive formats, so you can't play music until it finishes.

7. When the message Internal storage disk formatted successfully. appears, click OK.

The Internal Music Storage card now shows Ready, along with the drive's capacity, model, and a usage bar.

On any ROCK, it's normal for the available capacity to be slightly less than the drive's advertised size.

If formatting doesn't finish

• The drive is still in use: please reboot your ROCK from the Power menu in the top right corner, then try formatting again.
• The page loses its connection: your ROCK's IP address may have changed. In Roon, go to Settings > Setup, click Find next to Find Roon OS, and click your ROCK's new IP address to open the RoonOS Web Administration Interface again.

Formatting on ROCK in Legacy BIOS Mode

These steps also apply to a ROCK in UEFI mode that isn't on RoonOS 3.0 yet.

1. Open the RoonOS Web Administration Interface.
2. Find the Internal Music Storage section. If it's missing, your ROCK hasn't detected the drive.

3. Click Format next to your drive. Roon isn't usable while the drive formats, which can take up to 10 minutes, depending on the drive's size and speed.
4. When formatting finishes, the Internal Music Storage section shows that the drive is formatted.
