How to see a disk's remapped sector list?

I have a disk that I don't trust anymore since it reported
at least 2
sector read errors. However they seem to be gone now, so I
suspect the
sectors got remapped. Is there a way that I can get this
info from the
disk? It is a SATA disk:

wd0 at atabus0 drive 0: <Maxtor 6Y250M0>
wd0: drive supports 16-sector PIO transfers, LBA48
addressing
wd0: 233 GB, 486344 cyl, 16 head, 63 sec, 512 bytes/sect x
490234752 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6
(Ultra/133)
wd0(viaide0:0:0): using PIO mode 4, Ultra-DMA mode 6
(Ultra/133) (using
DMA)

The errors are logged in the SMART error log.

(the command 'dkctl badsector list' seemed promising at
first but turned
out to be different)

I don't know of a way to get the list, but smart can report
the number of
remapped sectors (atactl smart status)

I have been trying to find more ways, but no luck so far.
According to
the smart status, the error went away without leaving a
trace (in the
form of a remapped block) apart from a couple of entries in
the error
log. I'm suspicious about the disk, anyway.
