I have external HD with 2 partitions:
one is 180 Gb - Mac formatted
the other is 70Gb - PC formatted (FAT32)


The problem is that when I plug this 250 Gb into Mac , only Mac partition is visible.
PC formatted partition does not appear at all.
The funny thing is that Mac is able to display any USB thumb drives (Fat32formatted) for Windows but not the external Fat32formatted HD.

I've been told that tat I have to buy some programs that may help but being a student on limited budget I can afford to spend money just for experiment.

Is there some way to make this external HD (LaCie) to display both its Mac and PC partitions on Mac computer running on OS X 10.6?

Thanks for any good idea!

Go to your device manager and inspect the details of the drive. See if it registers any errors.

you shouldn't have any problems with the FAT32 part showing up on the mac

The only limitations for FAT32, (and this isn't limited to macs), is file no bigger then 3.9gb, (depending on how you look @ it, remember, i megabytes 1024bytes, not 1000, and the limitation is 4095mb. which windows will show as about 3.9), no bigger then 2tb, (again, about 1.8 really), partitions, (not your problem obviously), and the volume name must be CAPS and no longer then 11Characters.

you might have to mount the drive before you can use it, but i'm not sure how to do that on a mac, (very limited exposure to them), but i'm sure if you google it, it'll give you instructions

The other option is there are software you can install that wil let your windows machine read the HFS+ partition that your MAC uses, (MacDrive was mentioned in my quick search), and format the drive to HFS+ completely.

(it doesn't work the otherway round, as NTFS is a propriety file system, (so a Windows only sort of thing). the mac should READ the NTFS part, but wont be able to write to it. HFS+ is a linux file format, so by nature open source.)
