Does XDA already have campany partners in developing SD Bluetooth card accessories?
all sd bluetooth cards i've seen use sd-IO and xda1 dont support that
hi all..
just a quick question...
im getting a microSD card 8 gigs, and will be using it only for my kaiser.. now i dont know if i should get a sdhc or a normal card ? whats the differenc on the pda?
thanx

There are some 4 GB microSD that are not microSDHC.
8 GB ones are microSDHC.
I'm using a sandisk 8 GB microSDHC in my Cruise and everything is fine
On you exact question : what is the difference I know that SD is using Fat FS and SDHC Fat32 FS. There might be other differences, but I don't know what they are.
Did you check the wiki? I'm sure this had to have been covered before
microSD and sdhc
"sdhc" is a standard for microsd/minisd and sd for sizes larger than 2GB. Thus all 4GB and 8GB (and 16GB and 32GB) cards will be "sdhc" to work.
Or if you are talking about an adapter that takes a microsd and converts it into a standard SD, you would of course require a sdhc adapter. Whether you need one will depend on you, using activesync to transfer large files is painfully slow so putting the 8GB microsd in an adapter and putting that directly in your laptop/desktop can be much more efficient.
I use softick's card export to mount the kaiser drive directly on my desktop and can easily transfer larger files efficiently.

SDHC - secure digital high capacity
i don't know what's the difference between sd and sdhc (besides capacity), but there is some difference. however, device specification shows what it supports and kaiser supports sdhc
SD officially doesn't support more then 2GB. There are some out of spec 4GB ones, but they don't work in all devices as it's not an official format. To allow for greater capacity the addressing system has been changed in SDHC, along with the default format now being FAT32 instead of FAT16, and the reader/device must support that to be able to access SDHC cards. Some old readers won't read them for example.
So for 8GB you have no choice, 8GB SD cards don't exist.
But SDHC works like a charm in the Kaiser
EDIT: BTW while we're at it... does somebody else have some performance experience with the SanDisk 8GB microSDHC?
It's a class 4 card, so if we believe the specs this should mean 4-6MB/s write speed.
Now the other day I've bought a little Kingston set with a 2GB microSD, micro to mini and micro to SD adapter and tiny keyring USB microSD reader. The idea was to use the USB reader and supplied card as a USB key always on my keyring, while the adapters would be appreciated spares as I always manage to lose them...
The added benefit over a standard USB key being that I can swap the cards with the phone if I need to transfer large files.
So naturally I've put the 8GB card in the reader and started transferring some files to check the performance. Now that's where it becomes odd... I was getting sustained 14-15MB/s writes on the card! I'm not complaining at all of course, but it just seems rather strange nowadays that something exceeds the rated specs that much when everyone is battling for performance!
I've triple-checked with several large files, purposedly unplugged the USB reader right after the copy ended to be sure there wasn't some caching going on, but no, the files were always readable and complete...
Impressive, I've never seen such performance from either a SD card, let alone a card reader that often are slower than the cards... Even my good and fast USB key is slower than this topping at about 11MB/s...
The SDHC speed classes are pretty obscure though, the 4MB/s are supposed to be a minimum under some precise conditions...
Mny PC SD Card readers are not SDHC compatable, so you'll need to mount them via the Kaiser/Tilt/Vario via Active Sync.
Well one compnay here has 3 different 8g microSD cards..
one is 40eur - 8G normal
one is 43eur - 8G ultra II
one is 53eur - 8G sdhc
so still, which one will be faster in the pda?
i have a SD card reader that supports sdhc, so its no problem getting one of them, just want to know if the card sdhc will be slower in the pda couse of the secure stuff?
Normally, the 16GB micro sd card should be in stores this month.
If you have the time and money, I suggest you wait a bit longer and get one of those...
speed of the sd depends on it's class rating:
What is Class Speed Rating?
The SD Association has created and defined 3 speed
classes to help you identify speed and performance
capabilities/minimum requirements of SD/SDHC,
miniSD/miniSDHC, and microSD/microSDHC cards and
the host products. The SD Speed Class Ratings specify
a minimum sustained write speed for
SDHC/miniSDHC/microSDHC cards (Class 2: 2 MB/s;
Class 4: 4 MB/s; Class 6: 6 MB/s*).

You most likely won't be seeing a difference. PDAs are usually not capable of accessing a card at more than a couple MB/s, way less that what cards are capable of.
ok thanx... so cheaper / better
maybe ill wait for those 16g, if the phone will support it...
now im using card for navigation (need 2 gig), for pictures (cca 500megs), for Mp3s (cca 1 giga) guess 8g is more then enoug anyway ....
will get the cheapest, hopefully it will be readable on all sd readers
thanx everyone.

As said before, 8GB SD cards do NOT exist. Even if not noted by the vendor, any 8GB card will be SDHC, and will require a SDHC-compatible reader.
For my Polaris i'm using this one : http://www.amazon.fr/Sandisk-Carte-...2?ie=UTF8&s=electronics&qid=1215248577&sr=8-2
Works good. Transfer rate is not too bad.
is the internal sd card removable, like a micro sdhc, but inside the phone itself, or is it a nand chip of some sort.
It's some kinda of NAND chip that is soldered on the mainboard.
sounds like you have sd card failure.. is this an i9000m.. very common
i have a international version, and the phone works normal, it's just that in the file folder it states sd card , so I was wodering if it's a removable card, just like some of the new windows 7 phone.
thanks
iv put a 32gb card into my 8gb handset and ever time i put music onto my phone (drag and drop and doing it with kies) some of the music works and some go into a folder "LOST.DIR" with alien writing and sometimes the ones that do work have got 3/4 songs as one but play at 3 times the speed
Help Plz Anyone
new problem
i now know its not the file or a bug coz iv tryed with a 8gb the same music files just drag and drop and they work fine tryed again to the 32gb card and some of the files are messed up again
the 32gb card info:-
micro sd hc class 10(in a c) 32gb
the 8gb card info:-
sandisk micro sd hc 4(in a c) 8gb
Ok, maybe this is a stupid question, but can I plug in an SD from Z5c or Z1c, with data (pics and music)?
Yes, it will work. When first plugging it in it might give an option to use it as internal storage or external / removable storage. Select it as removable storage as using it as internal sometimes requires a full format of the SD card.
Thank you. I used the SD card from my Z1c, no problem. My new 256gSD is coming in the next couple of days. I'll wait to transfer all pics and music from previous devices. Might need the laptop for that...
