On Linux, I'm used to accessing e.g. HDD data through lsblk. However, sharing my WD HDD external drive with Linux on my chromebook (appears under /mnt/chromeos/externals/) lsblk or lshw will not yield any results. Why is that? How does ChromeOS provide access to these external hard drives for the linux environment?
Background:
The 1 TB WD HDD is most likely SATA, however, when trying to analyse it through smartctl (smartmontools), I get an "inappropriate ioctl" error when specifying -d ata, and prior an "unable to detect device type" error when not manually specifying a type. I suspect this has to do with how chromeOS mounts the shared folders (from the chromeOS filesystem) to be accessible to linux.
This has been asked as a separate question: https://unix.stackexchange.com/questions/743791/chromeos-to-linux-shared-hdd-not-recognized-device-type-for-smartctl
In sum, please be so kind and help me understand the chromeOS Linux integration better. Thank you so much! :-)
Update:
findmnt yields this as only detail regarding the mounts where the "shared files" (chromeOS to linux) are mounted:
+-/mnt/chromeos 9p
+-/mnt/external tmpfs
