I have tried what you said and it works! After a few days of fight :) I had a new u-boot in NAND, and correct rootfs on HDD but I still had WarheadSE "magic bytes" in first sectors of disk and whenever I plug disk pogo runs with old u-boot and debian didn't started. I wiped out first sectors, created new partition and all went well. BTW Thanks for keeping alive my pogo with dby azraleus - uBoot
Some time ago @shv published http://pogoplug.cwsurf.de/ox820-sata-uboot.tar.gz which is needed (if I understand it correctly) to make bootable SATA drive with debian. Unfortunately, I found that this link is no longer valid. Does anyone have this archive and would be so kind and publish it again? I'm trying to resurrect my old Pogoplug V3 Classic with recipe from this thread.by azraleus - uBoot
