Hard Disk Mounted but cannot record

Hello
Receiver can read internal hard disk and I can see it in Device manager. But after try to record program, I seen this error : " No HDD found or not HDD initialized "
I used FAT32 Format. Now how can I do to resolve problem?

I resolved this problem. Just I removed Hard disk partition and installed without any formatting in receiver. The receiver detected and request me to format it.
