Support for memory cards of more of 2Gb
It already does some time was in this entrance the compatibility of the Palm with cards SD about more 1Gb, and in relation to this it exists a program of Dimitry Grinberg that eliminates some limitations of the less recent models. But before speaking of him, I am going to explain which are the causes of these problems with cards of great capacity.
Cards SD, like the hard disks or the diskettes, have to have their space of storage distributed with a certain “format” (of the word to format there) to be able to keep data in them. Many file systems exist (formats) like are FAT, NTFS, and outside the world Windows EXT2, EXT3, ReiserFS, XFS, JFS and more than I have not tried. Nevertheless, the format used normally in cards SD is solely FAT (File Allocation Table).
FAT has in fact variant, according to the bits that use to direccionar the files. Although FAT12 was first, FAT16 is the one that has lasted to the present time. He is the one that used the MSDOS and at the moment still it is used in cards SD. The problem is in which the maximum size of a system of files FAT16 is of 1Gb (although other 2 sources even say that and 4Gb). Over this maximum size, we have to use FAT32, and here the problem comes: the Palm previous to the Lifedrive only supports FAT16 (to exception it seems to be of the T5). The conclusion is that these apparatuses will not recognize a card SD of 4Gb or more. The Palm that yes can use these greater cards, is T5? , Lifedrive, T|Later Xs and, since they bring installed to driver for FAT32.
We must be resigned to at the most use cards of 1 or 2Gb in our Palm? Then apparently no. As it said at the beginning of this post, Dimitry has extracted driver for FAT32 of the Lifedrive, it has modified and it so that it can work in another Palm older. Its unloading is gratuitous, and you can unload puncturing here it directly.
This program is gratuitous, but it does not guarantee anything either: in models of Palm it will work and in another no, it is question to try. By Internet the experiences of other users with this subject can be found. Thus it seems that Tungsten supports it to T3, when without these drivers, only could use cards of 2Gb at the most, and to only read them. Also it happens that, when using FAT32 chunk larger that FAT16, the access to the card is faster, to sizes still supported without driver. This still more makes interesting try this to driver. It is more, a better general design of driver seems to be the cause that the cards formatted with FAT16 tanbién read more express.
From driver of Dimitry, and with a little more hackeo, also one has obtained that a card of 1Gb works in a Zodiac. They speak of it in this forum and the file is here for unloading. The same seems to have done, but for Treo 650, although this already requires to make a ROM customized, with the risk that it entails. For the users of a UX it also seems to have a specific version.
A warning for navigators. Taken care of much with formatting with FAT32 unique card SD that you have, and soon doing hard reset. You consider that, when doing this reset, flock everything what you have installed in the Palm including driver, so until you do not return it to install, you will not be able to read that card again. And finally: in order to install these drivers we must copy the first file to the memory card, and there to the ram. To do hotsync direct to the ram will not work. Luck with the tests.

Thus it is, from the T5 supports to cards of 2gb maximums. hopefully these memories empiezen to lower of price… almost are worth half than palm! : s
by the way, the PAdict program is brilliant for which we are studying Japanese. salu2
Hello Carlos,
the memories of Palm have guarantee to work or in the Palm, but I use a normal one of Kingston of 512Mb and goes equal of or. If you can prove it first, is a good option to buy one of normal mark.
With respect to the PAdict it is a program that recommended Israel in ZonaPDA, I cannot remain I with his credit
Greetings. If somebody had patience and servicialidad to explain to me step by step how to modify the ROM of Treo 650 to incorporate the FAT32, since I was inicianto the process but it gave fear me because I read that an error can damage the Treo650 permanently. Perhaps somebody has done that it successfully can share with me the process step by step. Perhaps it can write to me to the E-Mai on the matter: melvinru@ racsa.co.cr
Beforehand, THOUSAND THANKS.
Excellent… I do not have a card of 1GB that way but I believe that perhaps it is worth the pain to install it for the moment at which one arrives at my hands…
Aid please! Then I have copied the patch to the PDA as she is indicated, I have a Zire 31 and after putting the card of 2GB she follows without recognizing it and therefore I cannot format it. What is necessary to do exactly? Thanks.
Little more I can decirte. To the people who work to him it seems that with copying it to the Palm already it is enough. To that not like and my E2, it does not seem to have adjustment. It is only question of the model. Surely Zire 31 is not compatible.
There is an option, that is to change to certain attributes of the file using for example the manager of Filez archives:
- To change “creator YOU GO” to the value that has file FATFS.
- To change “version YOU GO” to the value that has file FATFS.
- To activate the attribute “Backup” as it is file FATFS.
And perhaps to renombrar the file that you finish installing to FATFS, to supplant the original one.
The explanation is at the end of this page:

Thank you very much Marks. It follows without working to me but the intention is what counts:), by the sight model 31 is not compatible with the patch. I have a card of 2Gb and I cannot use it, arggg.
Good, again thanks and enhorabuena by the Web!
It goes, I feel that it has not worked to you. it either did not work me in the E2, so at the moment I remain with the card of 512Mb that I have, that gives much of himself.
And thanks for the spirits
