The Pi external storage mount script silently ran wipefs and mkfs.ext4 when a single USB disk was not recognised as an Umbrel data drive. Require explicit opt-in before formatting and block foreign filesystems. Fixes getumbrel#1956 Co-authored-by: Cursor <cursoragent@cursor.com>
Skip the Pi boot data-disk script unless umbrel-allow-external-format is set. Enable umbreld external storage on Raspberry Pi, install ntfs-3g on arm64, and exclude disks already used as the Umbrel data volume at /mnt/data.

Poll vcgencmd throttled state and kernel under-voltage / I/O error logs while external storage is mounted on Raspberry Pi. Automatically unmount affected drives and notify the user to use powered USB. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
When external USB storage is mounted on Raspberry Pi under Files → External, power-related failures (board undervoltage, kernel warnings, storage I/O errors) can corrupt data if writes continue.
This PR adds a background monitor that detects those conditions and safely unmounts external drives, then notifies the user to use a powered USB hub or a drive with its own power supply.
Depends on:

Raspberry Pi USB ports supply limited current. Large HDDs without external power often cause:
