The cd/dvd player I used in the SME server is IDE - it is not normally there, I just connected it for the installation, so it will be removed as soon as I collect courage enough to add the second hard drive (
red fish eggs - identical to the one where sme is installed).
I have done a lenghty memory check on the server without finding errors.... the cpu seems to run ok.... I even updated the bios... live cds seemed to work ok. I did run some hard drive checks with UBCD - no errors and also erased the partitions that seemed to have got there, which might actually have been what rectified the install problems.
I still imagine that the former hard drives started to give up due to age (they were made in December 2010) which was what made me get new disks and reinstall. So the rest of the hardware might be ok.
Why the installation was so troublesome I have no clue.
Or maybe I am just too lazy to - well what? I do actually have another motherboard and cpu both still boxed, exactly the same as those running the SME server, so not changing to those might be lazyness....
Anyway, when it looked darkest with this installatiion I started to contemplate to get a ready made NAS... but now I imagine that I'll stick to this setup.
