>Description:
SATA Host Controller A-173 ST-Lab
BIOS Ver. 8.4.84 

SATA Hard Disk Model - SAMSUNG HD250HJ
PC motherboard details - A-Trend ATC-5000 PCI 2.1 P1 200MHz BIOS ver. 1.0.08a (latest aveilable)
No built-in SATA ports 

This HDD works fine in SATA controller in my desktop PC, and I verify it surface - no read errors at all

When I try to install FreeBSD or even after install I got error message:

ad6:FAILURE - device detached
g_vfs_done():ad6s1f[WRITE(offset=38007275520, length=131072)]error = 6
/usr: got error 6 while accessing filesystem
panic: softdep_deallocate_dependencies: unrecovered I/O error
cpuid = 0
Uptime: 2m18s
Physical memory: 243 MB
Dumping 58 MB:unknown: timeout waiting to issue command
unknown: error issuing WRITE_DMA command


** DUMP FAILED (ERROR 5) **
Automatic reboot in 15 seconds - press any key on the console to abort

and after reboot it writes :
 
ad6:FAILURE - device detached
g_vfs_done():ad6s1f[READ(offset=99435380736, length=16384)]error = 6
g_vfs_done():ad6s1f[WRITE(offset=385406976, length=2048)]error = 6
/usr: got error 6 while accessing filesystem
panic: softdep_deallocate_dependencies: unrecovered I/O error
cpuid = 0
Uptime: 2m18s
Physical memory: 243 MB
Dumping 58 MB:unknown: timeout waiting to issue command
unknown: error issuing WRITE_DMA command

and reboots every 2 minutes after runs FSCK with different offset and lenght.

And finally it writes DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

What can I do?
