laptop hdd low level software recommendations

hi guys,
what is the best low level format software for a hitachi hdd?
ps. never done a low level on a laptop done on norm. desktop pcs.

 

If normal (high level) hard disk formatting is required, you can use DOS FDISK command to first erase and create partitions and then use FORMAT. It is also a good idea when you hard disk becomes inaccessible to see if it is just the system files that are corrupted. Most of the time, it is the case. SYS will do the job of replacing system files. Therefore, low level format is always of LAST RESORT when you encounter HDD problems.
