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

The errors are logged in the SMART error log.

(the command 'dkctl badsector list' seemed promising at first but turned
