Failure read_big medium error

Unable to install PCBSD 0.7.5 x86 on my pc with brand new 60gb hard drive. Keeo getting the error message " Failure read_big medium error asc=0x00 ascq=0x00 error=4(aborted)" etc, etc...........

I've formatted the HD to one large partition. When I boot from the cd I burnt I get to the install option but then get the error messages.

Freebsd installed OK.

Any ideas?

Cheers

it was the same to me but i've solved it (although still havent managed to install pcbsd :evil: but for different reason). try to burn the cd at a lower speed (i hope u burned it to a cd-rw). for example first i burned it at 10x, then a newer drive recognised it no problem, but an older one gave me the message above. then i burned it at 4x, after that it was ok. now i only have problems while partitioning...

Let me know if this fixes the problem.

Boot the install CD, then go to shell prompt.

Mount your root partition

# mount /dev/ad0s1a /mnt

cd over to /mnt/boot

edit the file loader.conf

Remove the line that contains ata.enable=1

Unmount /mnt and reboot. Does it fix the problem?

Thanks for great effort, Kris!

This problem is confirmed by FreeBSD ATA driver developers. They decided to turn ATAPI DMA off on FreeBSD 5.4 boot disk... Sad, but it's true. Certainly, DVDs are VERY slow on my EliteGroup i-Buddie (Transmeta Crusoe 5600 + ALi M5229 PCI Bus Master IDE + Sony DVD/CDRW CRX830E), but the only way to start booting and to work later is to turn that DMA off...
