Low-Level Format internal error

I am trying to do a low-level format to my HD.
The program show this message:

Code:: Current date and time: 03/02/2008 13:18:42 Hard Disk Low Level Format Tool 2.36 build 1181; http://hddguru.com Device details for HDS722540VLAT20 V31OA60A [41,17 Gbytes] Details are unavailable: Internal error. Please post this problem on http://forum.hddguru.com

Can I do a low level format anyway? Are there some risk?

I give more information:

Code:: BUS: ATA MODEL: HDS722540VLAT20 FIRMWARE: V31OA60A Serial Number: The program shows blank... LBA: 80418240 SIZE: 41.17 GB SPEED: 7200 RPM CHS:16383/16/63

And finally, I show you the SMART attributes screen showed by the program:
