Constipated XDA11s

Hi Good Peoples,
In trouble again. Hoping someone has a few suggestions please.
My XDA was becoming very unstabel and "crapping" itself - symptoms included deciding to reinstall itself with a hard boot and doing other strange software type things.
I bit the bullet and instead of doing (yet another) restore decided to reinstall from scratch in a completely clean fashion.
Right from the start, even before I started to add my data files, even when I was just setting it up, it seemed to be much slower than it used to be to do things.
I have now added all the data and TomTom software and its working properly, but seems to be very blooooodyyyyyy sloooooooooow.
Anyone know if there is a bit of software that can run diagnostics on it to see what the likley problem is?
I have 85MB allocated for programs and most of the data resides on the SD card.

i'm a noob and dont have an sd card but from what i hear sd cards run slower than native memory anyway?
have u tried overclocking using pocket hack master 2006 (personal fave)?
when you flash to wm5 i know thers a way to enter like a bios mode and there r options like clear storage n stuff, have u tried setting all those to yes? and then booting?
as i said imma noob but from what i know those should work
good luck.
*edit* sorry i thought u were using wm5 lol but hey no harm in trying lol. on my b.a wm5 is running atleast as fast as 2003se. I lurv helmi n mamaich n all them gosh they rule lol.

Thanks for the advice but the problem started before I loaded any data onto the XDA or SD card. It was running slow straight after a clean install.

Cause by an application or by a bad memmory
May the crapping is cause of one of the applications you have installed.
May try installing application at a time and observe the performance beofre adding another application. Make sure you reboot the it and try launching the applications.
Also maybe you have a bad SD card, maybe not the whole memmory of the SD may just a part of it thet when an application use it your problem will start to occur, so trying to use another SD may help. But if it is your XDA memmory has the proble even Hard reset wont help, you need to send you unit for repair.

Re: Cause by an application or by a bad memmory
I completely reinstalled the system as it comes and when I was configuring it, prior to adding any data etc, it was running like a dog, and the SD card is new and was not in use at that time. So it sounds like the memory may be stuffed.
Is there any way to check?

run a benchmark n compare the results with other ppls b.a's, if you would like i'll benchmark mine with tcpmp n tell you the results so u can compare.
this will prolly tell u if it is a memory problem

Thanks; a stupid question...... how do I run a benchmarK?

soz took so long to answel i;ve had exams lmao. ahh download tcpmp and benchmark with it, its the best media player and it can benchmark =)

FroYo + ADB App2SD: Goodbye, Kingston microSDHC?

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.

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...

[Q] Run from SD / Non Rooted Desire

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.

[Q] Bluetooth automatically toggles on/off HTC TP2

Ok, so I have the HTC Touch Pro 2 and was running froyo 2.2 (FXR07) and the bluetooth was working fine. It was actually working to route audio to my stereo headphone for listening to my audiobooks! Then, it suddenly stopped working correctly. I started having to manually re-pair the device each time. Shortly after that, it stopped allowing BT to turn on correctly at all. If I check the box to enable bluetooth, it begins cycling back and forth between turning bluetooth on and turning bluetooth off, until I uncheck the box. I tried updating to FFXR07.1 and had the same issue. I tried GBX0A and still had the same issue.
Note, I did carry over my data.img, which I realize I may want to go back and just try from scratch with the raw files and let it make a new data.img, but I will have to gack and try that again later to see.
Anyone got any other bright ideas on this?

This has been answered but I'll answer again. Delete the data.img. if you are switching between builds format the card first. Use titanium backup to backup any apps and info you need formatting is your friend.

re: Bluetooth
Thanks for the suggestion and reply. I did actually go back later and try recreating the data.img file completely. I tried this on both the GBX0A and FXR07.1 to no avail. I'll try formatting the card completely, but I'd like to give that titanium backup a try first. I'm not familiar with this, though and I'll have to see if I can find it and find out how to use it.

I wouldn't even use bluetooth at all yet. Audio routing isn't fully functional yet. Patience is a virtue my friend.

But that's just it...it WAS working fine...for a couple of weeks. Then all of a sudden just stopped working. And I Thought I'd seen in the dev thread where they thought they had it partially working.

In test kernels it works but test kernels use unstable code which can cause more harm than good to your build

So, at the risk of exposing my true ignorance here....what is the appropriate way to format the microSD card? Obviously I can't do it from within Android since that is running from the card. I have downloaded the HP format tool that is listed at the begining of the development thread, but it doesn't seem to detect anything. I'm assuming that it won't format the card while the card is in the phone, right? I'm guessing I've probably got to go dig out (if I can find it) the adapter that will allow me to plug the card directly into my computer, right? Or is there some way to do it from inside the phone with the phone plugged into USB?
Edit: Disregard. I figured out what I was doing wrong. When plugging it in while booted into WinMo, I had neglected to select to use it as a disk drive before. Once I did that, I was able to use either the HP tool or the Windows disk management tool. I used the latter since this one allowed me to set the allocation units to 4k as I had seen suggested elsewhere for performance improvement.

Well I hope you enjoy xdandroid I don't use bluetooth ever so the feature isn't a big deal for me. Everything I need works and I'm relatively happy with it.

[Q] Media files randomly disappear when connected as usb disk mode.

I havent yet found any solutions to this problem and decided to ask here.
This happens at only Sense based roms!
When I connect my phone as usb disk drive to pc and than back %90 of the time my media files randomly disappear. Many of my music files gone missing and my selected rimgtone / alarm etc mp3 also returns to defaults. Videos photos randonly hidden from system as well.
The files are there but android os cant access them. Only way is using an app like SDRescan this solves the problem until I connect the phone again to transfer files...
Please I have tried everything from formatting the sdcard with fat32 again to searching for .nomedia hidden files etc etc. No solution worked yet.
Again only Sense roms do this. I used MIUI and CM7 too they didnt have this behaviour I never loose any files like this.
Extra info: My phone went to service and mainboard changed and the same thing is happeneing so I have no reason to belive it is about the phone.
Only Suspect: SDCard. (The default one that comes with the phone) But it is not really a strong suspect. Cause it works in other roms.
Anyone has any solution? This is driving me crazy and I want to use my phone with Andoroid revolution HD rom.
Any help is appreciated.

123 hits and noone has any idea?

Could be something related to mediaserver...Nothing comes in mind as I'm playing paintball right now. Does this happen on all sense ROM's, (2.x - 3.x) or ARHD in particular?
Sent from my DZ.

Oh god an answer finally!
Ok this is my history with Desire Z:
bought phone:
Stock Froyo -problem
upgrade:
Stock Gingerbread - problem
rooted:
CM7 : no problem
MIUI (bulletproof) : no problem
lets try sense again after a long time!:
Revolution HD Rom: Problem again!!!
BTW I am not a noob. I have prepared an s-off/root and custom rom guide for the most popular forum in my country and helped a lot of people to root their desire z's.
Running ARevoHD rom with swap and supercharge with out any other problems at the moment.
But this stupid bug is driving me crazy. I gotto run SDrescan app after every time I use my sdcard as a disk.

Eh, sorry for not replying earlier, just came back.
Now, the behaviour you explain is odd. Have you tried logcat and see if there's any relevant output? I'd look for "Mediaserver" first. By the way, have you tried plugging the phone to another computer? I'd try that too.

The behaviour I told you isnt very uncommon. Many people have this problem. HTC answer it by saying "format your sdcard" some people says it fixed theirs. But my problem still goes on. Also I dont know where to and how to look with logcat. This happens when I choose DISK mode when connected with usb. And than when you go back to normal mode mp3's are gone until you rescan.

I cant believe I am the only one having these issues here.

Shameless bump

What brand card do you have? And remember, XDA is not your Tech Support site.

Yeah sometimes I forget this is a developer "only" forum and the residents are usually elite and unforgiving people and not to be disturbed by petty questions of "15 year old boys".
Excuse me for my question and thank you for your help.
I wont be disturbing the forum again.
BTW before the flames:
I respect all the developers here for whom I am very grateful of and I get triple the fun from my Desire Z by the works of them. Thank you.

People come in, they read it, but have no idea how to fix your problem, so they don't reply.
There could be a problem with the rom, where it doesn't mount the card properly. Also what OS are you running, and how do you unplug the phone? Many people ignore the saftey removal warning for flash drives an other devices, but sometimes it could be the culprit. Next time make sure you go through the process to safely remove hardware and xee if it happens again (On Windows, right click the little icon in the bottom right to safely remove, and on mac, drag the 'drive' to the trash bin (which changes to an eject button)

Nothing is changed how I remove my phone from USB. I tried everything and it seems unrelated how I unplug.
Because this happens when I change my phone from disk mode to charge mode even.
ALWAYS the same MP3's are lost I am sure because I change my ringtone to same mp3 everytime and when this happens that ringtone disappears from music player and I cant choose it from ringtone setup screen. So until I rescan my sdcard with an app I cant seem to see those mp3's. There is nothing wrong with MP3's too.
I am not sure if the problem is my SDcard or the general Sense based roms. I am truely lost in this case.
It never happens if I dont connect it to usb and change to disk mode.
My theory :
Somehow the mediaserver who archives the media files forgets half of my files when lost connecttion to sdcard. I dont know why or how.

i used to have the same problem, but it disappeared by it self i don't know how, try formatting it

Oh as I said in my original message I formatted my SD card with fat 32 system and this didnt work at all. I will try again but it is frustrating to backup gigabytes of data froma slow card meh
It is good that I am not the only one I hope to find some reasonable solution to this.
