Bug: Can only see first 4 partitions on USB drive, 5th partition not seen


I was wondering why I can only see the first 4 partitions on my USB drive, and not the 5th partiton. Is there anything that can be done so that it can see it, as I need to access the data on it.

Thanks in advance.

All my partitions were logical at the time of the first post. I stumbles upon something while googling that theres a 5 partition limit. So I changed one of the logicials into a primary and I can now see all 5 partitions. Which raises another question… why only 5 partitions?
