unusable.

I have a Dell D420 laptop with the ZIF interface and uses a 1.8" PATA
drive. I purchased a Kingspec 16GB SSD and installed it. The BIOS
recogonizes the drive. I am using the USB image to boot in verbose mode.
Upon boot the disk is recognized by FreeBSD 9.0 as follows (sorry for any
typos as i am reading this off the console):
ada0 at ata0 bus 0 scbus0 target 0 lun 0
ada0: <KingSpec KSD-ZF18.6-016MS 20120202> ATA-7 device
ada0: Serial number...
ada0: 100.0000MB/s transfers (UDMA5, PIO 512bytes)
Then i see these errors
(ada0:ata0:0:0:0): ATA status error
.....READ_DMA. ACB: c8 ....
.....CAM status: ATA status error
.....ATA status: 51 (DRDY SERV ERR), error: 84 (ICRC ABRT)
.....RES: 51 .....
As a result the disk is rendered unusable and i cannot write (partition) to
it. I did test the drive with a linux boot disk and i was able to format
it.
So my question is how can i make this drive work? Do i need to pass
something to the kernel at boot to lower the speed of the drive. Maybe to
UDMA66? Any help will be really appreciated.
