two external HD

[gustavo halperin <ggh.develop@gmail.com>]

Hello

I have one external HD of 40MB with two fat32 partitions and one ext3 
partition.
Today I bought another external HD, but now of 80MG and I create there 
four Primary Partitions of 20MG each one.

If I work with only one external HD, every think is OK, but when I try 
to use both external HD together always the small HD hang and then I 
only can mount it again if I unmount the Big HD.

I don't remember if the partitions in the Small HD were extensions or 
Primary Partitions, I also don't know if it is important.

Can any one see the problem of work with these two HD at the same time ??

 Thank very much,
