Okay, I loaded a couple of HP Museum's CD ROM images onto the SD card and checked it on the 49g+. Here's the data on the SD card:
On XP: used space - 1,335,754,752 Bytes
free space - 695,173,120 Bytes
On 49g+ free space - 678,720 KB
File Manager
After adding a third subdirectory of data to the SD card:
On XP: used space - 1,375,830,016 Bytes
free space - 655,097,856 Bytes
On 49g+ free space - 639,584 KB
File Manager
In both cases of the File Manager, I could see the subdirectories listed. This shows that the 49g+ can see all 2 Gigabytes of the SD card, it's just not coming up with the correct numbers in the File Manager display. That's a minor display bug but hardware/firmware is accessing all 2GB.
Final note, I do have a 50g with firmware 2.09 and it shows the same results. Hopefully a new version of firmware for both the 49g+ and the 50 g will correct this bug.
