Retrieving data from damaged HDD

[Adit]

Hello,
I have a PC to partition.
I used Partion Magic 8 per share in the HDD 2.At some point, everything is planted and now the PC does not start more ... It is 1 HDD Maxtor 250Gb by PATA133.
I tried to connect to another computer through an external BOX but I say "Unable to access." Su gestione disco, mi dice "Disco non allocato".On disk management, I said "Disco is not allocated."
I tried with some programs such as "file recovery" or even partion magic but I can not see any files ...
If you could tell me if there is a way to retrieve the data?
Thank you

If you find a CD of Acronis Disk Director Suite 10, show with that. Make sure that operations heavy on the partitions without first making a copy of data security ....
