The same problem with similar IDE Seagate HDD: 

ad0: <ST3160023A/3.06> ATA-6 disk at ata0-master
ad0: 152627MB (312581808 sectors), 310101 C, 16 H, 63 S, 512 B
[...]
ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=10<NID_NOT_FOUND> 
LBA=268435455

It had 312581808 sectors, but failed at >= 268435455 :

bash-2.05b# dd if=/dev/ad0 of=/dev/null bs=512 skip=268435453
dd: /dev/ad0: Input/output error
2+0 records in
2+0 records out
1024 bytes transferred in 0.163827 secs (6250 bytes/sec)

bash-2.05b# dd if=/dev/ad0 of=/dev/null bs=512 skip=268435454
dd: /dev/ad0: Input/output error

bash-2.05b# dd if=/dev/ad0 of=/dev/null bs=512 skip=268435455
dd: /dev/ad0: Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 0.149888 secs (0 bytes/sec)


Decreasing the 48-bit LBA threshold by 1 really helped:

bash-2.05b# dd if=/dev/ad0 bs=512 skip=312581808
0+0 records in
0+0 records out
0 bytes transferred in 0.000088 secs (0 bytes/sec)

bash-2.05b# dd if=/dev/ad0 bs=512 skip=312581807
1+0 records in
1+0 records out
512 bytes transferred in 0.019809 secs (25847 bytes/sec)
