Having read the thread, there are three things that come to my mind:
1) Have you tried to read from the disk at block zero, i.e. try something like
dd if=/dev/sda of=/dev/null bs=512 count=1024
This should read half a megabyte from the disk and for your hardisk be
finsihed as soon you release the enter key ...
Errors? and messages in dmsg?
2) The dmesg-output you mailed contains a call-trace about calgary. AFAIK
calgary is a IOmmu. Have you tried to disable it (try something like appending
iommu=none to your kernel commandline).
Have you looked for a bios upgrade? maybe you can get rid of the "broken bios"
messages this way.
3) A long time ago, there was a bios option for bootsector-protection, I've
never tried this, and I also don't have any idea whether linux sees that in
any way. If there is such an option, disable it.
Greetings
