So I have been getting frustrated with the small sizes of micro SD cards and how volatile they are, so i was estatic that i could boot from an HDD...until i tried it 3 separate times over 2 weeks and it didnt work once.
the first time i followed all of the instructions in Magpi # 50 and got stuck when i couldn't execute the "sudo chroot /mnt/target" command. after running around all over the internet trying to find out why the 'chroot' command wont work, no dice, so i formatted the HDD and reinstalled the os (Raspbian, newest edition) on the card.
then i tried the adafruit tuturial ( https://learn.adafruit.com/external-drive-as-raspberry-pi-root/overview ). that didnt work either.
so last night i reformatted the drive and reinstalled raspbian, and refollowed the MagPi # instructions again this eavning. it went well, no errors, but when i shut down and ejected the card, than rebooted, the pi behaved like the time when i was a 16 year old noob who forgot to unzip NOOBs before i installed in on the card.
so what gives? i set the OPT fuse bit and got the correct message, etc.
right now i am using a 1 TB Seagate Pipeline HD 2 (SN #: 5V1XZK3 ) connected to a StarTech USB 2.0-IDE/SATA (PN #: USB2SATAIDE )
