Hi,

I just try debricking WDL with 3Tb hard drive. I connected to UART port on board and may use console.

I boot board by tftp/nfs using run net_nfs command.

I use stock kernel image from apnc-021009-124-20111113.deb

But this kernel by some reason not determine sector size of my hard drive.

This is part of my output where we see that disc recgnized as 2Tb device:

…

I restored partitions except /dev/sda4 and booted it from hard disk too but after boot i see in dmesg same error…

so it means there must be some more configurations done for 3Tb drive.

Thanks

Can you provide good instructions for everyone how to connect their MyBook Live to the computer using the UART?  I am assuming there is a voltage level conversion curcuit between the board and the computer’s RS-232 port?

I know it means opening up the case.

Hi, so UART connection need soldering.

Pinout i got there  http://mybookworld.wikidot.com/wd-mybook-live-uart

I used http://foxlx.acmesystems.it/?id=106 this UART to RS232 convertor but You may find other UART to USB solutions on ebay for 4-5$.

Now I looking somebody who can give to me content of their /boot directory as tar archive…

I suppose that WD stock firmare kernel from rootfs.img isnot support 3T drives. They may use for production other kernel version or some flags to boot kernel with Block Layer 2T+ patch enabled…
