Hard drives wont mount - and Disk Utility can be accessed from DVD but won't format

[insanerr]

After hours of work, finally got the iAtkos 7 dvd booting up (I have had a successful install on a previous system) - I used "busratio=31 -v", however I noticed that during the verbose boot I could see that it was saying;

 

disk 0 s1 cannot mount

disk 0 s2 cannot mount

etc (from memory, not exactly like that)

 

But i didn't think anything of it.

 

Then when i went in to format my fat32 partition to HFS Journalled disk utility wouldn't do it, and then i tried mounting the other drives, and none of them would mount. Tried doing the repair thing, no luck.

 

Even trying to mount a drive from the same hdd i used in my last systems install didnt work.

 

My setup is

160gb: Win7, Leopard, Blank Space

1tb: my data

 

I have tried in ahci and ide modes.

 

 

Any help would be most appreciated - ;)

Its because you're using MBR not GUID. I don't reccomend GUID as it is incompatible with Window$ and some linuxes. Try my guide here.

Many thanks - worked 100%.

My problem was that I was using acronis to format it to fat32 rather than gparted to format to hfs+.
