IIRC, LBA is a sector index. how can it be 0x2FC2B95F00 if the whole
HDD has 0xAEA87B30 sectors?

dd: /dev/da0: Input/output error
0+0 records in

0 bytes transferred in 0.000318 secs (0 bytes/sec)

(no errors in logs)

if 0x2FC2B95F00 is a byte address,

root@muxx:/home/muxx # dd if=/dev/da0 of=/dev/null bs=512
skip=400645295 count=128
128+0 records in
128+0 records out
65536 bytes transferred in 0.062703 secs (1045183 bytes/sec)

(no errors in logs)

however, I don't see 0x2FC2B95F00 anywhere while dumping with usbdump.

I am quite puzzled. I will try and write the whole partition with
zeroes and large block size in the meantime.
