Put new 160gb hard drive in but only reads 127gb.Read somewhere SP 1 will fix problem.Downloaded SP 2 then 3. Should I delete SP 2,3 and reinstall SP 1.

To hard disk manufacturers, a gigabyte is 1000 x 1000 x 1000 bytes. To operating system developers, it is 1024 x 1024 x 1024 = 1073741824 bytes. That makes 160000000000 bytes = 149GB. Some of the remainder (149 - 127) is made up of file system overhead: these are the data that provide the "scaffolding" for user data to be written on the disk. However, that's 22 GB and it seems a bit too large to account for just overhead. I don't know where the rest goes.

No, you shouldn't remove later SPs. Your BIOS may limit the HD size or the HD may have a size limiting jumper. Once you solve that, keep in mind that XP usually won't make a FAT partition bigger than about 27GB [?] without making a fuss. ===================================== If at first you don't succeed, you're about average.
