Can we use the 8gb sd card from Trascend on the 700wx?

I'm dying to order this....Just need to know if it works first

I thought there were even problems with some 4GB cards not working... an 8GB one has less chance of working.

But, I don't know from personal experience...

The 8gig card uses SHDC, which the Treo 700wx does not support. I believe WM5 does not have the driver for it.

The 700p has a hacked driver (see XDA-Developers for that one).

I use a 4gig SD card without issues in my Treo.

I also use a 4gb sd w/ no probs @ all....I was just high hoping to condense my cards...I also use a 2gb & an old 1gb....Be nice to toss'em (aka sell) & use 1

Hmm so I wonder how hard it would be to hack a driver for wm5

From what I read on TreoCentral and XDA, it's not the inability to hack the driver, it is the absence of one. Only the Palm OS has a driver. I think us WM users are out of luck for the time being.

How about speed of SD card? What's the fastest the 700wx will go? I don't want to buy a card that is like 120x and have the Treo only write/read at 60x. Anyone know?

I'm kinda new at the whole SD card thing, I do know that 2GB are not really 2GB... so, I just got a 2GB Trascend card for $12, is it normal that it shows available 1.87GB? The number just seemed a little off.

Thanks...

It is about right. There are two things that make it looking less as the capacity indicated. One is the "accounting" standard. In computing world binary is the standard so 1 MB is really 2 ^ 20 or 1024 * 1024 = 1,048,576 bytes but manufacturers often use 1,000,000 bytes to denote 1 MB in the name of "simplicity". The OS displays the size in binary term so it will be about 5% less at the beginning.

The second impacts to the size is the formating. In WM5, mostly formatted in FAT or FAT16, which uses a small portion for the addressing table and any portion that can not be rounded up by binary addressing will be discarded as well.

Cool! Thanks for the explanation!

Yeah I did notice I lost like 2MB after I formatted the card on the device!

Ok, when I read this a few things went through my head, so I searched on Google and found some answers.

First is it possible that there is a Windows CE driver/files available that could be used):

Second, because of the size limitations (Fat vs Fat 32, reading higher than 2GB or 4GB, why couldn't the cards be partitioned to be read as 4 x 2GB:

Any thoughts?
