LBA solves all of CHS's problems. However, there is no reliable way for Linux or Parted to know that you're using LBA, so Parted may give you warnings about cylinders not being aligned, or the BIOS geometry being inconsistent, etc. You can ignore these messages if you are using LBA mode. (Old versions of Parted had problems, which have all been solved).
When your disk is in LBA mode, Parted (and most other programs) will say your CHS geometry is X/255/63 - unless you have switched from CHS to LBA.
