All this year I've been using a lexar 1gb memory stick pro with the memory stick pro driver

Anyway its just not enough for me, i need a 4g, I look at it like this [1g 1/2] for music [1g 1/2] for movies and [1gb] for apps. Anyway will a 4gb memory stick pro from any company work with my clie with the memory stick pro driver like the 1gb I always thought it would but then I saw all this stuff about fat 16 and 32 drivers I don't know what they are so could somebody kindly explain it to me.

Thank you

If anyone could help me now that would be nice since I'm planing on getting it this week.

This has been talked about many times before. And it's very device specific. If your "Clie" is a TH-55, there are some pretty severe limitations if you go for 4Gb sticks. You'd need a special driver found in these forums and you'll loose the use of the DSP chip when using the card for music. So it really affect your battery life. If you have an older clie, not many folks here would have the answer.

I have an NX7ov whats the drivers name?

I don't know about that model of the Clie's line. Here is a link to one of the various threads about the FAT32 driver for Clie's. http://www.1src.com/forums/showthread.php?t=93297&highlight=fat32+driver
They talk a little about some of the limitations with the driver. But I'm sure there are other threads that may address your specific model. Search the forums on "FAT32 Driver", and page through the threads to see what info is out there. That's how I found the one link above.

Best of Luck!

As of Palm OS 4, Palm added VFS (Virtual File System) support. VFS allows Palm Os devices to use expansion cards that are seen as removable media drives, formatted with the MS-DOS FAT file system. The original cards were formatted as FAT16. Recent cards are formatted as FAT32. The difference is in the size of the volume supported.

The smallest unit of space that can be read or written in one operation on a drive is the cluster. Each cluster must have a unique address. FAT16 uses a 16 bit address for each cluster. A 16 bit address yields 65,536 (2 to the 16th power) possible addresses. The maximum size of a cluster in a FAT file system is 64KB. 65,536 x 64KB = 2GB, so the largest size a drive can be when formatted as FAT16 is 2GB. PalmOS devices included a FAT16 driver called FATFS.PRC as part of the OS to read expansion cards in that format.

When Microsoft needed to support drives larger than 2GB with Windows, they went to a format called FAT32, which uses a 32 bit address. This provides a volume that can be up to two terabytes in size, though in practice, no drive is that large. (Windows NT, @K, XP and Vista use a different file system called NTFS, which isn't relevant here.)

When Palm introduced the Lifedrive, with a 4GB micro hard drive for storage, they had to use FAT32 to support the 4GB size, and had to create a FAT32 driver to read that larger volume. The driver was subsequently added to the T5, Treo 650/680/700p, and the TX.

Dmitry Grinberg ripped the driver from the LifeDrive and patched it to run other OS5 devices, and that's what folks are talking about. Tehre is apparently a further patched version that will work on some Clies, but there are caveats to using it. See the thread pointed to in other messages here for details.

Thank you so a 4gb wouldn't work with me with out the driver I guess, 1 question does every app read the driver and use the MS as it normally would?

1 question does every app read the driver and use the MS as it normally would?I use SD cards rather than sticks, but it shouldn't matter. The CS, SD, SM, and MS are hardware. FAT16/FAT32 are file systems. The circuitry in the PDA handles the hardware access. The driver handles the file system. I'd be very surprised if anything had a problem reading the card. Applications don't read the card. Palm OS does, through the driver. When the app needs data read from or written to the card, it uses Palm OS VFS calls to do it, and the OS handles it through the FAT driver.

Ok but what is this I hear about the built in apps not working with the MS?

Ok but what is this I hear about the built in apps not working with the MS?Which built-in apps? I don't run a Clie, and haven't heard that, so I don't know.

Like I said, apps that can use data on the card at all go through the Palm OS VFS facility to do it. VFS is a high level generic interface providing calls to create, open, read, write, close and delete files and directories on a card. VFS doesn't care what kind of card it is. It can be CF, SM, SD, or MS. The circuitry in the card slot and on the card hides that detail. VFS also doesn't know about file systems. It expects to talk to a driver that does. That's what the FATFS.PRC file in ROM is for. (If you install the FAT32 driver, it goes into RAM as FATFS.PRC. If the file exists in ROM and RAM, Palm OS uses the one in RAM.)

This will be true if the app is third party or built in, as long as it is "VFS aware" in the first place.

If the built-in apps you are talking about are the standard PIM apps -- Address Book, Datebook, Memopad, etc. -- those aren't VFS aware, and don't use a card, be it CF, SM, SD, or MS. Their data must reside in RAM. This is true for every Palm OS based system I am aware of.

You know, I think ill just buy a 2gb and with my 1gb I can do something like put my music on my 1g and put apps and movies on the 2gb, it just seems like theirs way too many problems with 4gbs and Clies,

Thanks for your help, but to clear everything up if I walk into a store a 2gb would work right away with what I already have, right?

FAT16 handles volumes up to 2GB in size. It's going beyond 2GB that requires shifting to the FAT32 driver.
