Default Media error... are there any way to help this?

I have the following partitions on /dev/sd0:

Code:
$ mount | grep sd0
/dev/sd0a on / type ffs (local, noatime, softdep)
/dev/sd0d on /usr type ffs (local, noatime, nodev, softdep)
And I am constantly getting errors from it in xconsole, for a few days:

Code:
sd0(umass0:1:0): Check Condition (error 0x70) on opcode 0x28
    SENSE KEY: Media Error
         INFO: 0x14dce8 (VALID flag on)
     ASC/ASCQ: Medium Format Corrupted
sd0(umass0:1:0): Check Condition (error 0x70) on opcode 0x28
    SENSE KEY: Media Error
         INFO: 0x14dce8 (VALID flag on)
     ASC/ASCQ: Medium Format Corrupted
The computer is still running, but I am afraid that it won't boot up next time it had to be turn off or reboot.

sd0 is 1 Gig in size by the way, so I've found myself an old CompactFlash (sd1) card in a used camera that is also 1 Gig... which I think my computer can boot from.

So I did a `fdisk -iy sd1`, and then create appropiate disk labels in sd1, newfs the two partitions, and did a dump and restore from sd0:

Code:

So yea I feel panic at this stage, the boot partition doesn't seem to be fully back up... as far as I recall though, /usr/xobj are there because I had recompiled Xorg in the past, it is just source code and since it is already compiled, those xobj errors can be safely ignore for now, for the purpose of being able to reboot into the Compact Flash anyway?

Regardless, I still proceed to install boot blocks in the new root:

Code:
# cd /mnt/root/                                                                
# /usr/mdec/installboot -v /mnt/root/boot /usr/mdec/biosboot sd1               
boot: /mnt/root/boot
proto: /usr/mdec/biosboot
device: /dev/rsd1c
/usr/mdec/biosboot: entry point 0
proto bootblock size 512
/mnt/root/boot is 3 blocks x 16384 bytes
fs block shift 2; part offset 63; inode block 24, offset 4904
using MBR partition 3: type 166 (0xa6) offset 63 (0x3f)
# umount /dev/sd1d                                                             
# umount /dev/sd1a
Can anyone see what might I have missed? Or if this new CompactFlash will be able to boot at all? (Assuming my computer's hardware/BIOS supports booting from USB Flash devices, I plan to attach the CompactFlash to a USB adapter.)

BTW sd0 is not the only disk I have on the computer, so it is not OpenBSD installed on just 1 GB of space... the full output of mount is as follows:

Code:
/dev/sd0a on / type ffs (local, noatime, softdep)
/dev/wd1h on /backup type ffs (local, nodev, noexec, nosuid, softdep)
/dev/wd0h on /home type ffs (local, nodev, nosuid, softdep)
/dev/wd2j on /img type ffs (local, nodev, noexec, nosuid, softdep)
/dev/wd2d on /tmp type ffs (local, noatime, nodev, noexec, nosuid, softdep)
/dev/sd0d on /usr type ffs (local, noatime, nodev, softdep)
/dev/wd2i on /usr/local type ffs (local, noatime, nodev, nosuid, softdep)
/dev/wd2f on /usr/ports type ffs (local, noatime, nodev, nosuid, softdep)
