I am a new subscriber, and am not sure if this belongs in the forum. I recently replaced my HD with a 250GB SATA disk, and reinstalled my distribution copy of WinXP/Pro. Since my distribution is prior to SP1, it isn't recognizing more that the 28-bit limit of 137GB. I modified my registry to EnableBigLba to 0x0000001, and used the DISKPART RESCAN command. Now the disk shows the whole disk, but I am wondering if anyone has the sequence of commands in DISKPART to either 1) Extend my primary partition, or 2) to create another partition (or Volume?). Thanks.
