[Q] Desire Z doesn't read sd card

Hi guys
I have Htc Desire Z was running on Cyanogen 6.1.1, I just got into Rom Manager download a another Cyanogen 6.1.1 and flash on top of it.
Now my phone doesn't read or mount ay sd card( I have try 2 different one).
Go to setting- application the sd card unavailable
Connect to pc just USB debugging only nothing else.
I have try format and partitioning the sd card.
So now I am stuck with that I can't flash another rom and run any app that acquire sd card.
Any one help pls.

That sucks. Maybe a bad flash right off top. Possibly try and reflash if all else fails. Goodluck, I've been using my Droid x lately which is a whole different animal as u know. On my incredible the only time it wouldn't read SD was with a bad flash. Post up if u get it fixed I would be interested to hear how this one turns out. Goodluck

try formatting on the PC and see if it works

I remember when using Windows Mobile, it was always recommended to remove the SD Card and SIM before flashing a new ROM. Not sure why and I haven't read anything along those lines for Android, but just an FYI. I would try re-flashing and go from there.

I couldn't flash or do anything without sd card.
It is totally suck man.
Can anyone know how to flash a rom with adb?

sd card unexpectedly remove

anyway to solve it?

SD card unmounted without you doing anything? What did you do before you encounter such problem? I experience it before.. when after flashing a ROM.. and it occurs.
But as I know flashing ROM can corrupt the SD card. So you may consider to format it.(of course save all the necessary files in it first)

a failing sd card will also cause this, i had a 16gb give up the ghost last week, only realised when i took the card out and put it directly into my computer and it kept un mounting.

It doesn't have to be a bad SD-card though. Android is pretty picky, so even some bad files or something similar might be the cause.
I had the same problem and for me (not everyone though) reforming the card on the pc fixed it.

im using the ota rom as i have not root it.. it failed 5 times in a row today... after restarting the 6th time it worked...

SD card keeps unmounting

Tonight I have been having problems with my SD card, anytime I try and download a file to it, I get the error "SD card unexpectedly removed" and then I can't access the SD card at all until I reboot
Any help appreciated. I'm running miui freshly squeezed with a class 10, 16 GB card

Back up everything you have in your SD card.
I had that same symptom once. After a few reboot I lost the SD card. It became unreadable/unformatted.
So, just in case. Back up your data first.

Cheers, done a bit more digging and its an issue for quite a lot of people. Backed up the card and using the standard 8gb that came with the phone. Ordered a new one too from play.com, as they are in the sale

I had the same problem unexpectedly too the other night. I took the SD card and via a usb adaptor I connected it to my Windows 7 computer. A window popped up asking if I want to scan and fix for errors or continue without scanning. I usually just continued without scanning when connecting my phone directly but this time I let it scan and fix. Low and behold once it finished the scan I tried it again in my phone and it mounted successfully. Ever since then I've had no further problems since either.

This happened to my 16gb mmc. Went on for a couple of months. I ignored it and mounted it manually. It died a couple weeks ago. I had no back up. Devo

Yup, same happened to me, lost everything on the memory card (though I had backups of the important stuff)

Same Problem
Guys i have been experiencing the same problem for some days now.
Found this post here; Was thinking the problem has been solved over here, but you all are reporting your problem.
Any there anyway this problem can be fixed or as most of you mention. The lifespan of the card is getting close.
Or I should just prepare for a new sd card (which am not ready for now).
My Case here is kindda different because when i boot into recovery, the sd card shows up and works fine.
when i boot into android then it cant be found.

???

[Q] Restarting many times dhd after a full restart

Hello,
If I do a full restart,then my dhd restarts itselfs after a couple of minutes for several times over and over again. If I remove the sdcard,there are no problems. If I remove the battery and put it back in together with the sdcard the problem most of the time is solved although I must sometimes repeat the procedure 6 or 7 times before its solved. Anyone has the same problem or a solution?
Thanxx (and sorry for my poor english !!!)

never read or heard something similar. are you using a custom or stock rom? have you tried a different SD card?

I have wiped and reformatted the memorycard and put all back on,but with no result... But I have not tried another memorycard,I will try it the next time... Can it be caused by a program on the memorycard?
Sent from my HTC Desire HD A9191 using XDA

did it happen also when you formated the SD BEFORE (!) putting all programs and stuff back on? i'm not a complete expert in android but for my knowledge i can tell, that of course there can be a problem with stuff which is on the SD. for me it sounds more likely that it is a hardware defect of the SD card or card interface. so i would try it with a fresh formated (on your pc) SD card.

Are you on a custom ROM or a stock ROM? If you're on a stock ROM perhaps you should try changing to a a custom ROM based off an official RUU to isolate problems?
Also maybe try a different SD card that is microSDHC no more than 32GB and Class 10 or lower.

Ok, the next time the problem occurs,I will try another sdcard. I'll keep your posted. I use the stock latest rom. The problem occurd after the last update with the sense. Also I went back to factory settings but after a while I had the same problem.

I figured out there's something wrong with the android_secure map on the sd card. If I remove this or empty it,there is no problem...so I reinstalled all of my apps back and moved it to the android._secure map like before...but after that I get the same problem after a cold restart. Can it caused by an app that is in the android_secure map ? If I get reboots after the cold restart, I take out the sd card and after a while when the phone is active,I mount it back again,that sometimes seems to work... Any ideas? Are there known apps that can cause problems with starting the dhd ?

Your English was fine.....and I have somewhat of the same problem. I gave my Desire HD to a daughter after buying another phone. The DHD worked perfectly for 18 months but when she put in her simm card it turns off completely and I have to manually turn it back on. However, if I have the dhd plugged into the charger it won't turn off. I have done a complete factory reset and wiped all the data off my SD card and all of my memory and it still turns off everytime, EXCEPT when the charger is on. Anyone?

I had the same problem. Tried formatting SD card and returning the data, then tried ANOTHER SD card with same data and it still rebooted. I found that problem is in android_secure folder and if I remove a couple of apps from there it boots OK. I thing that DHD has a limit on apps installed on SD card, because if I have too many apps on SD card it reboots like this. My understanding is that, after booting (this is only educated guess) it reads a list of apps installed on SD card, and it there are too many apps it just reboots. Really. Has nothing to do WHICH apps there are. Happened to me on 2 different DHDs. I have like 260 apps total, all the games on SD card. Dunno, I could be wrong, but when I removed like 3-4 apps from "secure" folder it started working. If I put them back, it reboots. Tried several times with different apps....

Thanx for the reaction...but the problem occured after the last sense update... And I have approximately about 220 apps installed. Any idea of limit number off apps ? Then I can try it...

My big problem
I Have This Problem in My desire HD with sense 3.5 too.
I have 16GB Class10 SDcard
I Don't Install any APP in my SD!
When I changed My DHD With My Friend's DHD (steel with my own sdcard) ,My Phone Problem is fixed , BUT in my Friend DHD (With My 16GB SDCARD), This problem occurred !!!
Both Of The DHDs Roms is ARHD 7.0.4
I Have This Problem In all sense 3,5 roms!!
This Problem is not for kerel or tweek or ...
DO You Think The SD Card Couse This Problem??
For ex This Problem is Not For CPU , OverClocking or UV !!?
PLZ HELP
(Sry With My Poor EN)
.

I think the problem is caused by the latest sense update...because the problem started at that point. But if you mount the sd card after restarting and waited 10 minutes,then it works most of the times. I now use holo launcher and stopped the sense...but I didn't try the cold restart so I don't know if this is solution...?

I too had problems with constant loop-rebooting after upgrading and it appears a HUGE BUG was introduced in the official Gingerbread OS ...
Check this link out, see how many hundred of others have this reboot bug, and add your two-pence:
http://code.google.com/p/android/issues/detail?id=25563
There does however appear to be a fix for those with rooted phones, simply install LINK2SD, it runs a boot-up script and allows you to save/link all your apps on SD card in a 2nd seperate partition (ideally use format ext4 for this partition) and makes the phone believe these are all installed on the local data space ..

Ah,thats the problem..so its not related to the sense but to android itself...
But I don't understand if so many people have this problem,why it takes so long to get a decent solution without routing the device ?
Anyway,we know what it is...for the moment I don't power off my dhd.

Sd card not detected

Hi everyone
I have a problem with my Sd card not properly being seen by any Rom at the moment. I noticed it when I flashed the new virtuous sense 4 Rom, as I couldn't view any of my pictures in the gallery and also no music can be found in any music app.
I decided to return to my backed up Rom which was runny suprise and the same problem occurred even though I had no issues before back up. I also tried a couple of others too.
I always full wipe between roms and just wondered why this has happened, have I pressed something in recovery or is my Sd card faulty? I can view my old photos by using my file explorer and selecting view with gallery and also listen to music this way also by using the native music player.
Any advice would be handy before I buy a new Sd card and start all over again.
In settings/storage it still tells me how much space I have on the Sd card so I'm not sure what's happend.
Hope someone can help. Thanks in advance.

I posted a solution for this in another thread, it seems that this is a repeated question.
For those of you that encounter problems of having trouble finding your gallery and music, but yet those files are still in you SD card
Follow instructions below:
1. Plug your phone to your PC
2. Use the search function on your PC and search your SD card for ".nomedia"
3. Delete all
4. Reboot your phone
TADA!!!

Hi
Thanks for the info but didn't help. I searched and deleted all .nomedia files then reboot but no luck

Heck, I don't know. Did you make a backup of your whole sd card, format it, then transfer everything back?
Are there any .nomedia files in the sd card?
