Hi,
Hope someone can help me. I recently bought a 160G HD and partition into
100G / 60G. I use it as an external drive, and when i use it on my XP Pro
laptop with SP2, i can only see the 100G portion. I tried to use it on a Win
2000 and XP Pro SP2 desktop, they both can see the 2 partition. Any idea why
my laptop cannot see the 60G? Thank

kaka
 
Hook the drive up to the laptop. Once it's recognized, do
start->run->diskmgmt.msc[enter]. In the graphics area at the bottom, locate
the external drive. Does it show a an unmounted partition?
 
It's possible the laptop is not capable of seeing partitions that extend
beyond the 137GB limit. There are several factors for the OS to see drives
larger than 137GB:
1) WinXP SP1/SP2 or Win2k SP3/SP4
2) BIOS must support 48-bit LBA
3) I/O controller must support 48-bit LBA

I'm assuming this is connects via USB, so that would rule out #3, and you
state you have XP SP2 on the Laptop - so the only caveat could be #2 - try
the manufacturer's web site an see if a BIOS upgrade is available for the
Laptop model. Other than it plain old not being assigned as Walter stated,
there's not much left.
