You are well within any limits with 500GB, a practical maximum for a bootable volume is something like 2TB in Windows XP which is about four times your new hard drive. The only thing I would suggest is consider having a Windows/Software and a separate Data partition for user data. That could be quite handy if you re-build frequently for whatever reason because you could keep the data in place and configure Windows to work with it. Regards.

With the impending fitting of a 500GB HD into my laptop, I wondered if XP has any optimum sizes for NTFS partitions on the main disk? I should be using partition magic to sort it all out once it is fitted, so partition sizes can be decided and adjusted as required. If there is an optimum size that XP likes to use then it might be worth setting it up that way from the start. Any comments welcomed.
