Are there any Disk Managers compatible with Linux?

[The Foxes]

To Whom It May Concern 

     I am a newcomer to Linux and looking forward to using it, 
but my Western Digital 2.1 GB Hard Drive requires the 
Ontrack Disk Manager to run properly (my CMOS only 
handles hard drives up to 528 MB).  Is there a disk manager 
that will run under Linux?  Any assistance on this matter will 
be greatly appreciated!!  Thanks so much. 

                                                     Sincerely, 
                                                       Mark Fox
