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

if 0x2FC2B95F00 is a byte address,

128+0 records in
128+0 records out

(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.
