Attach Problem To New Sql Server

I cannot attach mdf files which i have substituted and reloaded  sQl 2000 and 2005 after formatting my pc
both of the sales gives error
mdfs which i formatted and attached without any problem, now make a fuss
i thought that there may be problems with my files and i attached from my elder substitutes or from any other sample which i
had downloaded from net,  but still i have the same warning
i have formatted my pc several times and tested them
for instance i tried to load only the sQl 2000 and to attach the mdfs which i have generated with sQl2000
in case there is a superposition  but i still have the same warning

do you have any idea ??

the error message is below;
