Whot Maximum miniSD card cen u use in Treo 750 ?
i use 2GB card
will 4GB work ? (i think WM6 support miniSDHC aka 4GB+ )

I use a 4Gb Sandisk Micro SDHC (w/ adapter) on my Treo 750v running WM6 VFN ROM. It works perfectly.
But couldn't make it works under WM5 ROM.
HTH

Just purchased a 4G mini SDHC card to use in my 750 (after I install WM6 Rom). I can't get my XP computer to recognize that it is there. (Vista capable newer Gateway) The adapter will work OK with my 1GB card just fine. Do I need an upgrade for my desktop computer so it will recognize the HC part of the SD card before I can upgrade my mobile device or did I get a bad 4GB card ?? (I think it is a Panasonic).......
Any help would be greatly appreciated

If you understand portuguese, you can reade more info on my fórum in THIS LINK.
If you dont, can at least download the XP update HERE
On my note running WinXP works well

You need a SDHC adapter for your home computer to read the 4GIG MINI-SD card.
I had to buy a SDHC card reader/writer so my home PC will recognize the 4 GIG MIN-SD card.

Sandisk 2gb Micro SD :-(
Sandisk offers a micro SD card 2gb with adapters for mini SD and SD. My Treo 750 (WM6) does not recognise that card. An old 512MB card works perfectly but capacity is 90% used by TomTom. Sandisk card seems to be ok, it is usable with Windows XP and Linux.

Funny... I'm using the 2GB MicroSD from Sandisk with the adapter and it works fine on WM6 Aussie. Never tried the other ROMs, tho. It also worked under WM5, but after sleep it wouldn't recognize the card until I reinserted it.

WM6 2.23 same result
Obviously Treo 750 does not support all 2GB cards.

Not for me. In my 750 I'm using a 8Gb MicroSDHC (of SanDisck) with a Mini adaptors (previously I used it on my T650 with SD adaptor) and it work correctly.

wow You can back-up your PC HDD (or zip files)

Yessss, 8Gb it's wonderful, so I've not problem to decide what insert in it. Expecially with music now I can insert all I want.
I bought it to use with my camera (with support SDHC) and meantime with my T650 previously and now with T750.
But now I'm waiting for the 16 or 32 (as soon as in came in market and at low price) !!!

I just got my 8GB micro-sd sdhc card that I ordered from eBay, popped it into mini-sd adapter, put it all in the phone, and it works GREAT!!!
Mind you, this is a generic brand from China (the seller was located in Hong Kong or that's at least where the chip came from) and it works!
Here is the guy's eBay store:
http://stores.ebay.com/YES-E-GOGO
I ended up getting mine for $12.56 - free shipping!

does anyone have problems with their mini sd card where the sd is not recognized by the device after some time and must be reinserted?

problems with sdhc disappering after standby mode
yup i got this prob on my wm5 750. happened after install of sdhc.cab from this forum, but i read 4gb cards no prob. thinkin of updating to wm 6.1 and be done with it. otherwise might try some registry stuff from general--->hacking--->sdhc somtin somethin somthin. sorry cant remeber exact thread.

I use a sandisk 16gb micro sd with mini sd adapter - didn work with wm5 but works perfectly with wm6.1.

Palm Treo 750 and SDHC
Actually Treo 750 work with any micro and mini SD card - the only need is to download the sdhc driver for WM 5 and higher as like it is needed for many other devices who have hardware support for SDHC cards. You only have to plug the synchro-cable then wait until it connects with PC via activesync 4.5, copy the SDHC.cab to the device (understand the corresponding PDA or MDA ) doubleclick the cab and wait till the installation progress notifies about succesfull instalation and confirm reset of the os. After that your device should be able to recognize the SDHC card (regardless the capacity or type (understand the brand and micro or mini) ) and then you should be able to format it, and use as you wish. At least with my TREO 750it works

it will work but you gotta have installed the SDHC.cab (contains SDHC driver ), cause most devices with WM 5 and 6 need this. Since TREO 750 has hardware support for SDHC cards the only need is the SDHC driver. In my TREO it works fine (i had 4gb SDHC and now I have 16 GB and NO problem )

Sandisk MicroSD Adaptor Problems

Hi,
I recently bought a SanDisk 4 Gig microSD. My former phone (a Hermes with WM 6.0) was able to read the card and show its capacity correctly.
However, when i insert the card into its SD adaptor to use on my desktop or laptop computer, both systems were not able to detect the card.
What should be the problem: is it the microSD, adaptor or my computer systems ?
thanks in advance..

There is a problem reading some SD memory cards in Windows XP and in Vista - are you running Vista or XP or.......?
MSKB article http://support.microsoft.com/kb/939772/en-us gives more information for Vista users.
MSKB article http://support.microsoft.com/kb/921413/en-us gives more information for XP users.
Hopefully one of those will help you

It's probably your SD reader; it needs different firmware to read SDHC. When you bought your SanDisk, you should have gotten a USB-based reader that has the right firmware. Use it -- it will work.

actually, it didn't come with a card reader...it came with an adaptor: should there be a separate driver for the adaptor too? here is the URL of the product:
http://www.amazon.com/SanDisk-Micro...6?ie=UTF8&s=electronics&qid=1191048055&sr=8-7

Definetely problem with the reader. MicroSDHC needs a special reader that usually come with the card.
I bought SanDisk 4GB and I got the reader for free. It works fine with my XP (and fast).

if your in the us there is a great compactthumb drive styled reader at compusa fo 10 bucks. iforget the brand but its a major brand. works fantastic. i got it for the same issue you have

Is it the Iogear brand
please, is this the one:

Cannot Read 8gb micro sdhc card on pc

hi folks
this is my first post and any help would be appreciated...
i have a mda vario 3 and am trying to install software on the sdhc card 8gb by sandisak.
my computer sees this as an external drive but still says insert disk in drive d? some colleagfues say the pc cannot read that size of the card and requires a bios update????? any ideas what they are talking about and how i fix this problem
Thanks in advance

Hi tubzy,
I'm new to this topic, but I think you'll need a SDHC compatible card reader.
In the linked thread is a solution I think.

Bye
EDA-One

no solution still
hi eda-one
sorry this still is no soluton - i do hae the latest sandisk with the card reader and once all this gear is connected to the pc it says...please insert a disk in drive f??
even though the disk is in the usb card reader

did you try format it?

If you have used the card on an 'oldish' PC without the latest BIOS or Windows updates installed it may not be SDHC compatible even using a card reader.
You can also get a situation where formatting using the standard Windows formatter or even just writing files to it from your PC will corrupt its filing system.
There are various utilities available on SD manfacturers sites for formatting and recovery.
Check out the 'Formatting and Read/Write check util in the OEM section here and download the latest drivers for your reader whilst there.

Hope this helps.

Hi and thank you
HI
Even after trying this it still doe s not work,
I have downloaded the utility and attempted to run it but it says no usb found even though it can vonnect to a usb pen drive?? any ideas ??
thank you

I had that same problem when I first got my 4 Gb SDHC card and it was because I didn't connect the card reader directly to a USB port, instead I was using an external USB port. When I put it in to an onboard one, even though all of mine are on the back of my computer, it started working.

8gb card
Hi and thanks for your response.
i am sorry but can you please clarify what you mean to be onboard usb port. Is this the sockets where you normally connect any usb device eg a mouse to a computer or do you mean i have to take the computer apart and do it a motherboard level?
I am not very technical and apologise in advance if it sounds a silly question.
I bought the damn thing and was hoping it would and should work from out of the cardboard package. I can see this on the my computer as an external drive but when clcikcing on it it says insert disk
if the disk was faulty it would not work on the phone but on the phone it says 7.5 gb available and have stored some data there. So i think it it is a case of the pc not being able to read the card and from there i dont know what the problem is.
Any further light on this subject would really be appreciated

You have it right about what I meant. I did mean the sockets where you connect any USB device. You don't need to take your computer apart or anything. If that's what you are already doing then it's possible that the reader that you got with the card may just be faulty.

Not knowing what adapter you are using is a problem. I had similar problems with my first SDHC card and finally went to a local office supply store (Staples) and bought a "Sandisk MobileMate+ USB Memory Card Reader" for $15. It is a memory stick sized device and it accepts the SDHC MicroSD cards directly in it's slot. This works great on any PC so far.
It just may be the reader.

thanks!
This is a nightmare on elm street scenario.
I have finally tracked it to a faulty card reader, so i purchased another one. This one works and we have another problem - cannot copy data file path is too deep???????????
I am openeing another thread for that
Thanks to every1 for trying various solutions

I'm guessing you got a bad card..which is going to happen a lot with these high-cap cards, at least for a while. I am assuming you are using the small, plastic USB reader that came with the 8 gb card....that plugs directly into a USB socket? If not...I can tell you right now..the "older" adapters will NOT work with 4/6/8 gb cards. By this, i mean the adapter/reader that usually comes with the cards in the package. Also, it may sound silly..but make SURE you didnt, or are not, forcing the card into the phone/reader backwards...i know it's silly, but it's damn easy to do..and it usually trashes the card. My 8 gb just got in tonight...and it's working like a champ. I'm guessing you got a bad card. best of luck.

This is crazy. My phone reads the card just fine, but the card readers I have do not work period. 8G SDHC

Diamond CAN READ external SD cards!

According to HTC service manual http://forum.xda-developers.com/showthread.php?t=410653 (picture attached) there are somewere an Y cable and SD card reader !!!!

Till now we just proved the existence of a working SD card reader-cable connected.
Special reader? Special Cable? According with HTC service manual no special software is needed, so the solution is in the HW

MAKE A SMALL Diamond like microsd card reader?
people get some entrepreneurial spirit 3 million diamonds are going to be sold
know some manufacturer which can make it for $10 a piece and you sell it for $49, YOU SELL 250K, YOU MADE over $10 MILLION, theres a life.
or VIEW THIS! http://www.tca-inc.net/usbmatousbbf.html and http://www.bizrate.com/memorycards/oid796436093.html
will that work?

Another USB reader
Check this out.

Nice prices, altough shipping will be put on the price.

I almost hate to ask, but has anyone actually tried plugging in a card reader or USB drive?

If someone managed to cram the features of the smart cable into the space made by the extended battery back cover, we'll have a neat little extension to the phone

Bringing up an old topic.... But just for the info here it is:
I worked with it many times. It can read the SD card but only in special conditions. You cannot use it as a USB host and read-write files etc.
The cable is a special cable so don't bother look for a ready made one commercially.
Regards!

i think its purpose is for service only

I think the SD Card reader in the picture is simply a USB OTG Bridge that can transfer data to USB client devices.
Here is a similar product:
http://www.everythingusb.com/sima_hitch_usb-101.html

Forget hitch, the reader is a plain card reader.
And yes it is used for servicing only.
I could go into further details later if you want or even show how to build one.

Is there something useful here?

if that's a plain card reader, it means the Diamond is an USB host or OTG device, right?
if that's true, we could provide an external 5v power to the card reader, and connect card reader's D+ and D- pins to Diamond to get it work, right? ... is it required to connect the both sides' Vcc and Gnd pins? Or, maybe the external power is not required?
thanks,

It will only work for servicing purposes. Nothing else. About the connections you are right.

I see. So it's useless for the rest of us.

Sandisk ultra dual drive

Hello all! I have bought dual flash drive by Sandisk, size 64gb. For some reason when I connect the device I cannot use it, and when I try to set it to MTP, it "jumps" right back to reverse charge. I have unrooted stock ROM and would like to keep it that way if possible. I have tried usb debugging, and formatted the device.
Help please.
Thanks in advance!

Try to format sd card in reader with HP USB Disk Storage Format Tool. Google for it. I'm using same sd card moded to use with 2 sim cards and it works fine (with more than 50GB of data occupied). Or maybe the card died

Please notice that it's not a card but a flash drive.

From SanDisk page:
64GB and 128GB Dual USB Drives come preformatted in exFat file system and certain mobile devices do not support exFat. In this case please format the drive in Fat32 file system.

Weirdly P9 is not listen in compatibility page even when P8 and P7 is... but I often use OTG drives with my P9, from cheap sd card reader for 3$(with microUSB so I use usb-c dongle...) to even external SSD is working with it, so lack of OTG support is not a problem.

It's not the cover. Will formatting it to fat32 won't affect the size of the flash drive I can use? And Is there a way to format it with unrooted phone? Because I will not be at home for the next few weeks.

nope, formating just change file system/algorithms of how files are stored in drive. But you need to remember that 64GB drive will have just about 59-62GB of REAL size, its because of difference between how the manufacturer calculates capacity (decimal-based) compared to how a computer calculates it (binary-based).
And you dont do formating on phone but on PC:
1. just plug it to PC.
2. backup files if you have any on it.
3. right click on that dive in "My Computer".
7. select format -> Quick format
8. select FAT32 and then hit format.
9. done.

Thank you for your answer. I know to format through a computer, I just won't be near one for the next few weeks. What file system should I format into?

umm... I mentioned that 2 times: Fat32 format :]

It should be fine if it's in Reverse charging. In my case, I'm using a USB-C to USB (female) adapter (check Google if you can find one). It works fine, my P9 can even read the contents of my 1TB external hard drive. Probably something wrong with the USB-C part of the flash drive itself?
