Is my hard disk failing?

On my Dell Mini, Ubuntu 10.04 Lucid Lynx has this Disk Utility program (palimpset) that keeps saying I have 200+ bad blocks on the disk, but also that the hard disk is "healthy".  Apparently this is a problem with that program.  Instead, install gsmartcontrol from Synaptic and use that to check out the SMART status of your hard disk.  That shows my disk actually has had no bad blocks, which agrees with what the disk utility from Windows 7 says (the name of this utility escapes me at this time).
