What size SD card can the Sony PRS-505 hold?

[Hop-frog]

I looked through the manual, but cannot find the specifications. Does the Sony PRS-505 hold fulls-size 24 mm SD cards, 20 mm miniSD cards, or 15 mm microSD cards?

Is there a limit to how large the SD card or the Memory Stick Duo card can be? Can it handle 32, 64, and 128 GB cards?

IIRC they originally claimed support for up to 2GB cards (full size SD), but according to our Wiki folks have used it successfully with 16GB SD and 8GB Memory Stick Duo...

memory expansion: SDHC (tested to 16GB) card slot and Sony Memory stick Duo slot (tested to 8GB).

Also from the Wiki...

5. SD Card, which the manual claims supports up to 2GB cards, while field reports claim capacities up to 4GB are supported. With firmware update, SDHC up to at least 8GB has been verified to work, but you must format the media with 64K clusters for reliable data access. DOS/Windows: FORMAT /FS:FAT32 /A:64K Linux: mkfs.vfat -F32 -s 128
6. Sony Memory Stick Pro Duo, which the manual claims supports up to 8GB cards. (8GB cards have been verified to work.) Note that this will not take Memory Stick cards, or Memory Stick Pro cards.
Every connector is standard, and it works as you would expect on any generic device.
There is some confusion over the card slots for SD and MSPD cards The PRS-505 (is different from the PRS-500 because it) can use both card slots and the internal memory (210.0MB) at the same time. That allows for over 10GB of storage in the reader.
When plugged into any PC with a USB port, the PRS-505 works as both a SD and a MSPD card reader/writer. The internal memory is also available as a drive letter.

It may work okay with bigger cards, but due to the age of the device it may be harder to find any data on that.

I did not know this forum had a Wiki. Thanks for the help!
