Can I alter the LBA on the HDD without corruping data


I have an older LG laptop with what I have discovered is a 250Gb hard drive although it shows 137Gb I have upgraded the Bios because I thought that was the problem.

It seems however the supplier originally altered the LBA so the drive is set to 137Gb. LBA = 268,435,455

My Question - Can I alter the LBA to the correct factory value so it reflects 250Gb without corrupting current data ?
Or should I backup all data and then alter the LBA and then format ?

thanks in advance.

  1. What OS and service pack are you running? Versions of Windows prior to XP SP1 don't support disks beyond 137GB.
  2. Thanks for they reply. Right I discovered that also in my browsings. Currently XP SP3
