Dual Vista installations, 64bit installation can't see 1st hard drive

Computer: Dell Inspiron 1720, 2.4 Core2Duo, 4GB RAM, 2 internal SATA disks.

1st hard drive, from the factory with Home Premium, single NTFS partition.
2nd hard drive, installed Vista x64 Ultimate, single NTFS partition.

When booting to the 1st drive, Home Premium can see both disks and all
partitions as expected.

However, when booting to Vista x64 from the second disk, it becomes "C:"
and does not even acknowledge the first hard disk is even in the
machine. The only other problem is that the 64-bit installation doesn't
keep the laptop as cool and is noticeably warmer/hotter. Aside from
these 2 issues, Vista 64 runs well.

TIA,
Mike

Run Disk Management in Vista x64. Assign driver letter to the
partition on the first disk drive.
