Hi,
I am using dopod 818pro. But whenever i use a 4gb(mainly kingstone SD memory card) memory card, it shows, "no memory card installed". But i can use 2gb memory card (any brand).
My config is as follows-
windows mobile 6.1 professional
processor- OMAP850-195MHz
memory- 50.02 mb
ROM version- 7.0.0.7 WWE
ROM DATE- 7/5/8
RADIO VERSION- 02.19.21
RAM size-64mb
So please help me to use 4 GB memory card.
SDHC
The HTC prophet doesn't support SDHC cards (over 2 Gig)!
i'm using non sdhc 4gb card from transcend. make sure your card is not sdhc...
oh yes, but you still need a driver
hey man, if you have a normal SD card with 4GB, it still will not just work ,you needed a driver of some sort, sorry, I had it, but changed my computer some months ago. Maybe someone else has it?
do you?? i just put the card in & my prophet recongnised it.
SD
I used to have MMC and I thought the disable power management would resolve my problem of getting my files disappearing from the card if the path 2 or more folders deep, but when I changed the card to a normal SD (2GB), I had the same problems happening sometimes (but not as frequently as before), but I'm getting another (harder) problem now. I'm saying harder because this seems to be very hard to track because it happens when it wants!!
sometimes the card works for several days without any issue, but sometimes I get a blank card. even though when I look at the status I see the used space and the free space, but when I open it with resco or file explorer it's just blank.
and I even got a worse problem (fortunately it happened only one time yet). since I set the ie and opera cash to the card, these programs created their temp folder on the card again, but everything else was totally erased! I used a recovery software to get my data back!!
as I said, it happened once, but the usual problem is I just see nothing on the card until I shut down, and boot my prophet again. and sometimes it doesn't work until I do this several times.
I think I've looked everywhere to find a solution for my problem, but I didn't find any real solution for it. I've tried several roms, several cards, always getting the same problem. I don't think it's a hardware issue because of its nature. I mean how could it be a hardware issue if the data disappears without even touching my phone? if there is a hardware issue I don't think the card would be recognized at all! or (at least) it won't be recognized after I move it (causing the weak or loose contacts - if any - to disconnect) however, I don't think it's true, because the contacts are clean and tight, and like all HTC devices, the SD slot is high quality.
if anyone can offer a real solution to my problem, then I'll say he/she is the one who enabled me get the full of my HTC Prophet!
So thank you in advance. whoever you are!
Windows Phone 7 represents a radical leap in the way the filesystem is presented to the user compared to WinMo. No longer will the user be able to access the true, underlying filesystem in any direct way - the OS will abstract the file system to a single view of all files - making no distinction between files stored on internal flash, or removable storage, or even striped across both similar to RAID0. The file system functions as a Virtual Unified Storage system.
WP7 will support SD cards, but the functionality is different now. The user data is striped across the SD card and the internal storage. This results in functionality similar to RAID0 - if a member disk is pulled from the set, the entire set ceases to function. Similarly, in WP7, if an SD card is pulled from a deployed device, the device will go into a "reduced functionality" mode - where you are only able to make emergency calls. Upon re-inserting the SD, the data is restored and the system functions normally as it would before the card was pulled. If the card or its data is not available (got corrupted, lost, eaten) - The phone must be "hard reset" to restore full functionality and all user data will be lost.
My guess is this was at least partly done as a method to lock down the security of marketplace apps.
I can see some advantages in this, in that it doesn't matter to a user whether it's on the memory card or on device, but will this completely screw up using the device as a USB storage device?
Thanks for the info! Would this have similar benefits of raid0 (increased performance w/sd card)? I guess if you want to upgrade your card it sounds like you'll have to give it a hard reset. That sounds like it could be a bit of an issue for many users. I wonder if, while it may allow support for an sd card, they may eventually only support non-removable cards because of that?
Makes me wonder why bother then? We all know that sd/micro/minis have a tendancy to corrupt after a year or so (depending on use) so surely its bloody pointless??
Just rely on the internal storage like iphone etc.

I'd rather have it user removable such that it can be upgraded\expanded.
Also, if the card isn't constantly removed\inserted and is of a decent quality, then it'll probably last the life of the phone.

I think that this is just a new requirement, and OEMs had been developing devices with SD cards, so it accomodates this fact.

But which is more reliable? built-in memory like iphone or SD cards?
For those of you interested in why they would want to use a MicroSD card inside the device instead of just soldering a flash chip on the board and the issues that can come with MicroSD, here's a great blog post on the topic.
because... of course we can all "simply" solder a flash chip on the PCB...

I was referring to the manufacturers. Read that blog post by a very, very, smart guy (he hacked the original xbox) and it will make sense.
Removable storage??
What do you mean removable storage? Last I heard it was all non removable?

Is there anything which indicates how large of an SD card WP7 can use? Apparently initially phones will only come with 8 GB of memory, and that on an internal card. That seems way too small if you wanted to store music and videos.Would it concievably be possible, as soon as you bought the phone, before anything additional is loaded, to pull the card, copy everything to a 32 GB card and reinsert it?

8GB is the minimum spec. There will certainly be devices with larger amounts of storage. It should support at least 32GB.
How is this a performance benefit if most consumer SDs are rated Class 2 (i.e dog slow) and many people prefer to be able to swap cards at will? Class 6 cards are usually pretty expensive, and swapping SD cards on-the-fly is not uncommon...

WM7 phones will have an external storage card slot but it will become apart of the internal drive and not be used in the since of what we currently use it. when an external sd is inserted it is formatted to becomes part of the main internal drive something like a raid system so if you pull out the sd card phone will not boot until you put it back in, and i do believe this is also the same if you replace the card you might have to hard reset to get the phone to work.
A fred has a test device with 40g (8 internal and a 32g SD card)
You can access the filesystem with the "Remote Tools Framework" along with a filesystem plugin that wraps the Sirep services.
The sirep background services must be running on the device. Unfortunately these need to be flashed in or inserted via imageupdate.
Sirep is the sucesssor of rapi. Some tools include wpget, wpput, wprun etc.

So, that being said.
Whilst Its a well known fact that "external media" such as Micro SD cards will not be user accessable, would it be possible to manually replace the cards?
For example, if a user dared to dismantle his/her device to access the card.
Then remove it, copy the partition on there to a larger piece of media, extend the partition to fill the card & then place that back before re-constructing the rest of the device.
Do you know if that could work, or are there measures put into place which prevent this? I guess some manufacturers may glue cards in, but that can be got around. I mean software wise, would doing this mess up the opperation of the device?
If that wouldnt work, then how about simply replacing the card & doing a hard reset? Any idea if it would simply accomodate the new card?
Im just trying to think of work-arounds as I know many people will be dissapointed with the variety of 8GB devices out there.

From what I've heard, the last option there, with forcing a hard reset is likely to be the only one that works, but it should work. OEMs may well glue down the microSD cards though.
I think quite a few devices will be using microSD cards internally, as it lets you release 3 versions of a device with different storage sizes very easily (just slot in an 8GB, 16GB or 32GB uSD card and release it).
I also doubt there will be many only 8GB devices. I know we've only seen leaks of 8GB devices, but it makes sense to test on slightly cheaper hardware, and make sure the OS works on the bare minimum of hardware.
Good eveneing dear community
I realize that FroYo was a major leap forward for quite a few of us, especially those limited in phone storage (I'm talking about Nexus One and Desire owners in particular). However, I think there is something seriously wrong with those App2SD capabilities.
I recently got the impression that moving applications to SD storage is killing SD cards too fast. Just after the first official FroYo OTA, I discovered and used the posibility to force move applications to SD storage using ADB shell. The result was that virtually any application could be moved out of the phone's internal storage. So far, so good.
But considering that we get updates from the market every few hours, SD cards are under much more pressure now than they were designed to, aren't they? I'm saying this, because in the exact same configuration I mentioned above, my cards keep dying. Before the OTA, I bought an expensive class 10 Kingston microSDHC card and the performance was indeed remarkable. However, after the OTA and my ADB stunt, my card would get mounted as read-only every few days now. In addition to that, I can't run any applications on the card anymore and the entire system becomes unstable. Unmounting the card using the Android system settings is not possible and neither is formatting. Instead, my phone would sometimes reboot. At first I thought this was a problem with my Kingston SD.
When I ran some tests and did the same things with the official 4 GB card that shipped with my phone as well as with another 8 GB card that came with an older Nokia phone of mine I realized that it wasn't a problem specific to my Kingston card. All of them showed the exact same behavior. This is not just annoying, it also causes data loss, which in my case is unnacceptable!
Has anybody experienced the same? Is this a problem of Android 2.2 or is it just the way microSDHC works? What, besides mounting said damaged cards in a Laptop in attempt fix, can we do about it?
Thank you for any suggestions.
My next phone must have at least 8 GB of internal storage...
Define "dying".
If by dying you mean Android reports there's something wrong with your card, then more likely the problem is software-related rather than the SD being overused.
I got the "your card is fubar" message from my phone but it was as a result of me damaging the file system with a sketchy file manager app. I put it in my computer, did a scandisk. This found the problem, fixed it, I put it back in my phone, voila, perfect again.
Or your problem might be related to the method you're forcibly moving the apps to your SD card. Since you're doing it with ADB rather than through the operating system itself, it's possible apps are corrupting your card's file system as a result of not realizing where they're located. Just a guess.
In any case, SD cards don't (and won't) die from the sort of use you're describing. What might be harmful is storing frequently-used cache on your SD card, but that's not something that you're doing.
Keep in mind that SD cards are intended to be used in cameras, camcorders, etc, and these things write a lot more frequently and aggressively to the card than a little app storage here and there.
I'm not exactly an expert but I'm definitely what I'd call an enthusiast, and let me tell you with certainty: you really have nothing to worry about. Your problem is most likely a software (or related file system issue) or else caused by a one-in-a-thousand random hardware defect. Android, or more specifically, app to SD, isn't a problem.
Maybe you've heard of solid state drives for computers, these are becoming more common. I use one in fact. They operate using technology similar to SD card storage and if ANYTHING was going to stress these things, it would be running a whole computer off them, temp files and all.
Finally, if you're still a little afraid, let me remind you that in fact your phone itself uses the same kind of flash storage as an SD card. Every phone, MP3 player, and similar device does. So in a sense, if wearing out your storage is a concern for you, isn't it better to wear out a replaceable SD card than your phone's irreplaceable internal storage?
----
So now assuming you trust me that there's nothing to worry about, I would suggest you stop forcibly moving apps to your SD card as a possible long-term solution. If you stop getting card problems, you know what the problem was. Since this means you'll run low on storage, I'd then suggest you install a custom OS that allows you to force-move apps from within Android itself, such as Cyanogenmod.
I've been using this mod since it came out and have had no problems. As mentioned above it must be software related to your phone.
Sent from my HTC Desire
Thank you so much for calming me down. I just got the impression that my cards are toast. However, as long as there is a possibility to fix this using my laptop, I'm on the good side.
I disabled that ADB stunt, let's look what the next few days bring.
Just an idea: if your phone (or the sd slot, for that matter) would be somehow messed up, wouldn't that show the same symptoms? It would even explain why _every_ card acts that way. Maybe it's a bad contact in the slot, who knows...
I have followed the steps found elsewhere on this site to allow almost any app to run from SD. I have seen cautionary notes about unmounting the SD card and the potential nasty effects it can have. (Including how touchdown even cautions against moving the DB to the SD card).
Under what conditions could I unmount my SD car. I know that connecting to my PC and choosing to connect as disk drive. What about using HTC sync?
If I do unmount the SD card is there any precautions that I can take to avoid corrupting theses apps or DB (Force close before connecting)
Next in a much more general question. Is it possible that whith a future release of Android OS that all apps, widgets and data can be run from SD card regardless of whether root access is required or not. Or is more of a core functionality that will always prevent some apps from running from the SD.
Appreciate any and all replies.
Come on guys a little help here
Please I have seen that this group is filled with Brainiacs that could answer this question in their sleep.
I know that it is a noob question but I did research it first before posting it.
Anything from anyone would be helpful
I use Froyo A2SD, and have never had a problem. I certainly don't do anything special.
On your second question, it won't be a problem in the future because the hardware is better specified. If you look at the Desire Z and HD they have way more app space in the first place, rendering any form of A2SD obsolete.
Regards,
Dave
Thanks Dave!
Dave,
First off thanks for the reply.
1. Do you ever use HTC sync yourself? Also it should be noted that I ran the modification to force apps to run from the SD not just the ones that are market approved ones. Again the worrying note from Touchdown about corrupting the DB
2. Actually want I meant was will the phone we have (Desire) manage run from SD better with any future software updates. It is disappointing to have an 8Gb card and not be able to load up with tons of apps.
As much as I would like to update my phone that is not an option for me as I have had the phone less than 2 months.
The issue is quite an unique one i may recall. Because, i googled all my way over time fetching if i could get any similar issue to solve my self up seemingly.
The story:
1) What's working:
I can make calls, save contacts, modify settings, add alarms, use internet for browsing, etc.
2) What's not working:
I cannot take pictures, install apps, auto sync of google account doesnt show up, cannot download anything, etc.
What is my phone loaded with: Its a note 2 indian version and has 16gb internal and 16gb sandisk external class 10 card.
The verge : The point here is, there is about 8gb of data in sandisk memory card and also 5gb already occupied by personal files in phone memory. But i come up being showed nothing, infact not even the apps i installed. The stock apps all are there but no other app shows up and stock apps have their memory values as 0.00B in there app info page when i open it. So weird problem. The 16gb memory card when taken out and installed in othersamsung phone works like a charm by also showing what the files are inside it. When i connected my note 2 to pc, i tried to get it recognised by kies but it says "unsupported device alert" so waste of using kies over it. Now another thing, this is very weird to myself as i never saw anything like this happen to anyphone of mine. As i connect this note 2 to my pc through samsung data cable, i see the phone's storage information way to constraint. I have attached a snapshot of the storage blocks window taken from my laptop screen. If anybody understand what this memory picture suggests. please let me know. Anythings else if required, feel free to mention, i will prepare update it here. I find this error first of it's kind for note 2.
If anybody got any idea on what this problem is, please guide me for which i would be truly thankful to you.
Not even one reply?
Please guys, somebody help (-_-)
