[Q] need help, with app2sd and or partitioning etc

hi Hopefully i am in Right section - not sure what is meant by Not posting a Rom ??
I have a Garmin Nuviphone a50 with android 2.1 , have successfully rooted phone with z4root, I am pretty sure I have partitioned my SD card tried on a mac with EXT-fuse and tried on a windows using mini-partition (as instructions on this site about Partitioning) both ways seem to work -
However here's my problem when i start up Link2SD application it always says :-second Partition not found - /dev/block/mmcblk0p2: - make sure you have 2 partitions both primary .
I partitioned with Fat32 and Ext2 (also tried with Ext3, Ext4 and few others) but always says same with link2sd.
Does anyone know how I can get my apps to SD card or what my problem is or have any suggestions . As i get that message space full so need to move some to SD card (phone supposed to come with 4gb internal memory, i have 16gb SD card also) why is it still full

[SOLVED] Phone's SD card not showing up in My Computer

Hi,
I just bought the Desire S and it comes with an 8GB SD card. When I plug my phone into the computer to browse the SD card, the SD card doesn't show up in My Computer. I've tried USB storage ON and OFF, debugging Mode and nothing works.
When I go to Computer Management -> Disk Management, the SD card shows up as "Unallocated". I cannot assign a drive letter to it as well.
I took the SD card out of the phone and plugged it into the computer using a card reader and it showed up in My Computer and was working fine. I put it back into the phone and plugged the phone to the computer and selected SD card storage option on the phone and I can't browse the SD card any more.
I've already formatted the card as FAT32 using Windows 7 before putting it into the phone.
I can browse the SD card just fine using a file explorer on the phone.
What could be the problem? why isn't the SD card showing up when I plug the phone into the computer?
I'm running MIUI 1.9.30 ROM, but the problem was also present with the original HTC ROM as well.

maybe you should try to format it through phone's settings, even better if you try to use a sense rom

Do you have htc usb drivers on your pc? Not sure if this they are required to browse the sdcard whilst in the phone, but they maybe?

The best you can do, you must format your SD card (all partitions) with your recovery (Ext3 or Ext4).
If you have used 4EXTRecovery or CWM, it's easier. (I prefer 4EXTRecovery )
At the end I think it will be ok

I downloaded the "HTC Sync" tool and installed it but it doesn't recognize the phone probably because MIUI is installed on the phone.
Does anyone else have MIUI installed and managed to get it to work? Or is there some USB drivers I need to install?

But Windows doesn't recognize Ext3 or Ext4, so I still won't be able to browse my SD card on the computer.

Indeed, except if you use Droid Explorer on your PC (you can read all partitions from your phone with).
Except your SD partition who's must be in Fat32, all the parttions must be in Ext3 or Ext4.
That's why I'm write that's you can format your Sd card with your recovery.
For exemple, mine is:
System => ext4 => capacity :549 MB => free: 101MB
data => ext4 => capacity :1156 MB => free: 427MB
cache => ext4 => capacity :142 MB => free: 138MB
sd ext => ext4 => capacity :0 MB MB => free: 0 MB
sdcard => fat32 => capacity :29543 MB => free: 15369MB
In my pc, the only partition that I can read is sdcard

I tried Droid Explorer but it is buggy, incomplete, very slow, and overall crap.
I tried RCMix3D 1.5 ROM with Sense 3.5 and Android 2.3.5, and still the SD card doesn't show up on the computer. I have HTC Sync installed, but it crashes when I plug the phone in.
The SD card is formatted as FAT32.
Is there anything else I can do to browse the SD card on my PC? What did you guys do to get your SD card to show up on the PC for the first time?
Thanks for your help.

Some daft questions:
Did the SD function fine ever, eg with stock ROM when you first got the phone?
Have you tried an alternate SD card in the same phone?
Have you tried a different USB lead?
Have you tried on a different PC?

Have you tried another USB cabel?
Swyped from my Desire S

[Solved]
I found out what the problem was. After having a look at My computer -> Properties -> Device Manager, I found that two of the USB Controllers were not working properly and the SD card was detected as an "Unknown Device".
I uninstalled HTC Sync, fast boot drivers, and anything related to Android or HTC from my computer.
I then uninstalled the USB controller drivers by right-clicking on each and selecting Uninstall, and the same for the "Unknown Device". After a restart Windows started scanning for drivers for these devices and they started working perfectly again.
The SD card now shows up in My Computer when I plug the phone in, without the help of any HTC drivers.
I hope that helps others who come across this problem. Thanks to everyone who tried to help me with this problem. I appreciate your help guys.

i had that too.... i formatted it wiht my desire hd and it worked

Great to hear that this is resolved.
Best to edit your opening post #1 (using Advanced edit) and prefix the title of the post with [SOLVED] so as to note it's resolved.

[Q] SD card won't mount - Have I bricked it?

Hi guys.
Almost total noob here - not quite, but still.
I have a Pico/Explorer.
I rooted, flashed CWM 5.05, then a MIUI ROM.. all worked well. Then I wanted to try the new Triumph HD ROM. Initiall install was succesful.
I partitioned my SD card with 1024 ext3 and a swap of 128Mb
Wiped, installed ROM, no problems.
I didn't see that int2ext was supported (by command line, apparently) so I tried installing mount2sd from the play store.
After enabling everything in that app, I rebooted.
Phone became stuck on lock screen.. would not respond to any touches or buttons. But the UI updated when the battery got low, made a noise on low battery etc, and the time was updated.
I booted into recovery to test the buttons, all work fine. I checked my partition log and it said various errors like could not find this or that mount point.
I partitioned again, this time is was extremely slow. I put the SD card into my mac to add the images, but it wasn't found.
Now when I partition it does it really quick - on inspecting the log, it says "err: /dev/block/mmcblk0 does not exist!"
I can't mount the /sdcard or the /sd-ext in recovery.
Have I f!cked my SD card or my device?
Thanks for any help.

Connect your sd-card to pc using card reader if it shows sd-card then ok
If it not show ur sd-card then run minitool partition wizard
And find the sd-card there and format it and delete the sd-ext partition and re-create it using recovery
And never use two memory script at one time
Before using the another memory script remove the previous one

little pico

Thanks dude.
When I plug it in with a USB card reader, the SD card doesn't show - in minitool or anywhere else at all.
I think it's dead. Will have to buy a new one.
I will be careful with overclocking in future
Thanks again.

Put your card in the phone and boot into recovery.. Then mounts/storage and try to mount usb storage when connected to pc.. If the mem card shows up in your pc then try putting the card in a non android phone and delete the partitions.. Even my sd card didn't show up in a card reader.. But it showed up when I used a non android phone..

make sure your sd card is usable - connect it to PC and check if it is being read. If yes, then continue. If no, then replace it.
Backup your entire SD card.
Delete all partitions and make one single partition using the Minitool Partition Wizard. Once done, try partitioning with the Recovery. this way you can ensure max compatibility.
And btw, only use swap if you are using Swapper, and only if your ROM supports it. Not all ROM support swapping. I recommend you to set swap to 0, our Pico is capable enough to run flawlessly without swap.
Once done, Factory Reset, Wipe Cache, flash your rom again and after one reboot flash mounts2sd or int2ext. Never use two scripts at a time.

same problem
It happened only with Triumph ROM for me no matter what i do the doesn't mount when i connect via usb tethering to my pc..I had to reboot into recovery for the memory card to show up in the pc..Can any one help me on this?
I never installed any secondary memory script..Just flashed the latest Triumph version after a superwipe....
The memory card never shows up on the pc but only in recovery..

format using minitool partion
format using minitool partion it'll fix sd card errors

[Q] MicroSD problem

My Pico stopped recognizing the microSD card. Can't view it nor formatting, nothing. Under Windows, Linux, Android recovery... I was using 2.3.5 with Link2sd and now my 8GB card showing up 30 megs and it seems to be locked for some reason (like locked SD card by the lock. but microSD doesn't have any locks) Please help me, what can I do? Could you reccomend someone who can help me with it?
I know that I removed card without releasing it properly from phone... I had some important files there :/

Have u try using windows disk management to see the drive is present or not?
If a partition was corrupted or missing, most of the time it won't be shown on my computer

I tried everything on a pc. Windows shows unformated 30megs sd card, Minitool Partition wizard shows it: http://i.imgur.com/wRLzSmU.jpg
Linux and GParted pretty much the same. I can't format it under pc to get the previous 8GB size...

Go to control panel->administrative tools->computer management
Try formatting from the disk management section!
