[Solved] CM in WD SATA adapter: Where is the drive?

[W. H. Heydt]

Two issues, really.

1. How does one locate the attached drive? Neither lsusb nor df sees it.

Code: Select all

pi@raspberrypi:~ $ df
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/root        3661568 880560   2606876  26% /
devtmpfs          218416      0    218416   0% /dev
tmpfs             222688      0    222688   0% /dev/shm
tmpfs             222688   4528    218160   3% /run

2. mkfs documentation is...less than crystal clear. Other than specifying "-t ext4" and the drive (once I find out how to locate it), what other parameters are actually needed, and how does one determine the values to use? Or would I be better off not worrying about making a file system on the drive and just using "dd" to copy the root file system from an SD card onto the drive?

Have you tried

Code: Select all

lsblk

It lists all block devices.

Code: Select all

pi@raspi3b:~$ lsblk
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda           8:0    1 14.9G  0 disk
mmcblk0     179:0    0 14.9G  0 disk
├─mmcblk0p1 179:1    0   60M  0 part /boot
└─mmcblk0p2 179:2    0 14.9G  0 part /

Thanks a bunch! It stands out there....

I think I got confused because, when one is flashing the eMMC, the CM looks like /dev/sda and the partitions are /dev.sda1 and /dev/sda2.

Next step...get root onto the SSD...
