Hi Bob,

Thought I'd do two posts or it would be too long.

As to your second post - if you look at the second screenshot you sent us, you will see that your Lenovo machine listed your external drive as 58.42gb primary and 16.11gb unallocated.

This means Windows can see and use the 58.42gb partition, and it can see, but not use, the 16.11gb partition. This is normally because the unusable partition has not been formatted in a way that Windows can understand.

The "cure" for this is normally to right click and format the unallocated partition as NTFS, and assign it a drive letter - to create a new usable partition of 16.11gb. The alternative would normally be to extend the 58.42gb partition to the right to incorporate this unallocated space and make the external drive just one big partition.

The reason it shows in Disk Management as less than 80gb in total is that drive manufacturers have a more generous way of measuring GB than operating systems do.

I am not as familiar with Xp , but to see what is going on on your Xp machine, could you please send a screenshot of it's Disk Manangement window

Thanks
