You can provided you have added validation rules or apex code to detect the duplicates in your org. There is no in built dup detection feature available.
Natively, Data Loader does not offer a de-dupe feature that would error out duplicate records when you insert data in SFDC using the data loader. You may want to use the Unique field property to define one of the key fields in your object as Unique, so that when you are inserting data into this object, the system identifies duplicate entries into this field. However, this will only work based upon how the data has been prepared, and may not be a full-proof solution.
There are a host of tools and apps available on the AppExchange that you can explore for preventing duplicate data being entered into SFDC. Some are free while some are paid (of course the paid ones will have additional capabilities)
Do you mean preventing duplicates on the basis of a particular field value? I' afraid this can't be done through dataloader. What you can do is to create a trigger or validation rule to perform the de-dupe check on the basis of that field value.

Good luck!
