Hi

Can anyone please help.

Just received a new USB 2 750gb external hard drive to replace my current 60gb HD that the PI is booting from.

I first tried to just plug in both HD into the PI (both had Y power cables so expected power to be no issue) but the PI just crashed.

Removed both HD and plugged both into my lubuntu netbook and did a simple dd of=/dev/ ...... if ... etc and cloned the 60 to the 750. All went ok. The netbook after a reboot sees the same files on both.

Plugged in the 750 to the PI but no boot up. As I'm headless I changed the /boot/ back to root=/dev/mmcblk0p2 PI now starts but no files found or anything.

As I've got a spare OS on a 2Gb different card I tried that - boots as normal but the PI can't seem to find the new HD.

Any ideas ?????

Thanks.

Think I've fixed it. Completely deleted all partitions on the netbook and reformatted to EXT4. Now the PI at least sees it. Just going to do dd copy again and see what happens.

Thanks for reading.

Another update - seems that the PI just doesn't like the "Sonnics" branded external hard drives from amazon.

Bus 001 Device 004: ID 14cd:6116 Super Top M6116 SATA Bridge

Removed the hard drive and put inside another caddy (different chipset) and now the 750 Gb shows perfectly.

Managed to clone my old 60gb onto it and its booting as normal.

Only problem now is I can't get it to use the full 750 space. Last time a sudo resize2fs /dev/sda1 worked but not now ?

xbian@Raspberry ~ $ sudo resize2fs /dev/sda1
resize2fs 1.42.5 (29-Jul-2012)
Filesystem at /dev/sda1 is mounted on /; on-line resizing required
old_desc_blocks = 4, new_desc_blocks = 44
resize2fs: Permission denied to resize filesystem

Any ideas ?

is the fs ext3/4 or ext2?

It was ext4. Got sick of messing so just wiped the whole partition table in lubuntu and dd a new xbian install on top and resized as before. Worked this time.
