Computer info: HP Vectra VL420 MT WinXP Home SP2 LBA on Intel Pentium 4 CPU 2.00 GHz HP System board A08 Chipset: Intel i845 Rev: A3 Southbridge: Intel 82801BA (1CH2) BIOS: American Megatrends, Inc. Version: JA.01.07US Graphic Interface Version: AGP version 2.0 Intel(R) 82801BA Bus Master IDE Controller SD RAM 512 MB PC133 NTFS (did I miss anything?) I appologize in advance for the long read. This computer came with only a 10GB Seagate drive. It has less than 300MB left of unused memory, so I tried installing a 250GB Maxtor. It is only recognized as 30GB in the BIOS. I don't understand this because I have WinXP SP2 and LBA is enabled in the BIOS - Not only that, but I have another 300GB Seagate that I want to install as a slave (I had previously installed this one as a slave to the 10GB but had the same problem with only 64GB being recognized. I don't understand why my BIOS isn't recognizing it at it's full capacity since I have the latest version of BIOS and LBA is indeed enabled (I thought SP2 was supposed to correct this problem). My hope is that someone out there can walk me through this step by step (from erasing the disk to installation) because I've been working on this thing all day long and nothing I've tried seems to work. The 10GB drive has to go. I want to install the 250GB drive as my master, copy the 10GB drive to it (I have Casper XP 3.0 for this purpose), and then install the 300GB drive as my slave. Both the 250 and 300 GB drives have data on them, but I'm not worried about losing it in the partitioning & formatting. Can someone help me? Pleeeeeeeeeeease??
