[Q] Corrupt SD Card during Gold Card process

After my "kefuffle" with http://forum.xda-developers.com/showthread.php?p=8484070#post8484070
I had to play around with making multiple gold cards. Unfortunately one of the cards I had to use was my 32gb SanDisk microSD. After editing the hex code during the gold card process my computer failed to read the card. I then proceeded to format the card.
Windows explorer can't format the card in quick or full format mode. I downloaded a third party SD formatter (Philips or something) and ran both a quick format, and a full format on it. After running the SD formatter windows explorer was able to recognise the SD card as having 31gb of spare space. I was able to copy files to the SD card.
As soon as I put it in my Desire, it said random errors like "SD card ready to dismount" and "SD card damaged please format". After formatting the card with the Desire's format tool, the card is recognised and it says there is 31gb free space. I am then able to plug the Desire into the computer and enable "HTC Sync" or "Disk Drive" mode. HTC sync doesn't recognise the SD card, but windows explorer does when it is in disk mode. I am able to copy files to the SD card, although as soon as I eject the phone, the Desire attempts to check the SD card for errors and says the card is damaged.
Surely there is a tool out there I can use? It has the functionality to store files some of the time, surely not all hope is lost? 32GB microSD cards are freakin expensive and I don't want to throw it out...

Get a linux live cd, start GParted and delete every partition on the SD Card. Create a new FAT32 partition and try it again.

Sorry I'm nub, what the hell does that mean?

http://gparted.sourceforge.net/livecd.php
Grab that and burn it to CD/USB/whatever, and use that to delete all of the partitions on your card (plenty of guides online for GParted)

I got that problem too but my 16gb microsd read only 8mb. Can't format. Gparted can read as well.. :'(

I had the same problems with my SD card on my HTC hero... don't panic I solved it with this software...

This is the instruction video that I used to understand what to do and create an ext2 as well...

For me worked like like a charm!

I tried that but it didn't work. I was able to partition it, however once the software had applied the partitions, it showed up as "Unformatted", "Other" and "other". Whereas in the video it showed up as "Fat32", "ext2" and "linux swap".
I tried it in my Desire anyway, and it recognised it, but if you took a picture then connected the SD to the computer as a disk drive, the image taken becomes jumbled (literally). Once ejected from the computer the Desire is unable to mount the SD card properly and says it is in "Read-only" mode. In that state I am unable to eject/format the card.
I haven't tried Gparted yet. Wouldn't that be the same as deleting and creating the partitions?

I see.... I don't know about Gparted, but now that u remind me, also for me it didn't work immediately..
I don't remember what I did exactly but I formatted the sd card 3 or 4 times, after I use the video's method, and I also formatted once with win7 and at the end I formatted it again with the phone..
I did it and suddenly the SD started to work properly..
Now is working perfectly since I've done it and that was 3 weeks ago..

it doesnt work with my MicroSD.. it still shows as 8mb when it should be 16GB!! guess its corrupted like hell..

Tried Gparted...I was able to create a fat32 and ext2 partition (wasn't able to do ext3 or ext4 or linux swap - kept saying "sd possibly corrupt") However still had issues with phone reading it.
I'm just going to take the card back. I've had it a month, but worth a try.

Mystery of disappearing RzR Nandroid and all those MB's

Hi, just a little background first....
I'm sure many of us have already tried out the RzRecovery, which was good, but, for me anyway, had a fatal flaw.......
and left a big legacy when I abandoned it.
The inability to successfully see Nandroid on External SD Card, even though Recovery says it made the backup there, after we choose /sdcard/external_sd as back-up path, and in Recovery it appears to be there, even you can erase it.
However, when you looked with File Manager, like Root Explorer, the Nandroid Backup, and associated folders is nowhere to be seen, as shown below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now, what you would expect to see there is this:
nandroid/GINGERBREAD.XXKK1-BDCSA-20120115-0052//boot.img/system.tar.gz/data.tar.gz/cache.tar.gz/secure.tar.gz
This is the structure of the nandroid under RzRecovery....a nandroid folder, with a sub-folder for each backup, which contains the files boot.img, system.tar.gz, etc, etc.
However, it must be there, you would think, coz RZRecovery can find it, and even use it to restore, and it can be erased, so where is this data on our devices???
I have discovered where exactly RZrecovery was storing this back-up data, but it is not where we expected to find it.
What I did was go to Storage in Settings, and Unmount SD card....thereby disabling the external storage (SD card).........
this is where RzRecovery was supposed to have put my back-up.....but guess what!!!!!!
Look at the Pic with external storage SD Card unmounted on my device:
Still got /sdcard/external_sd
Properties of /sdcard/external_sd showing 402 MB
/sdcard/external_sd showing nandroid folder
Showing GINGERBREAD..... Backup Folder
Finally, Folder showing Backup Files
Now, I stress, above caps were taken when External SD Card was unmounted, disabled.....
So, when I remount External SD Card, all above become invisible on your device, you will not see the nandroid folder.......
and you do not know where that 402 MB has gone!!!!!
I think this is a fundemental flaw in the RzRecovery, regarding the external SD card, and where it stores back-ups supposedly being saved on External SD.....
Instead they are being saved in a folder/directory, on the Internal Storage/SD....and are not visible when the actual External SD is mounted......
this folder has the same name as the name given to the External SD, but it is not the external SD.
Would anyone with more knowledge of Android file system, as it applies to our device, care to comment????
There has to be a way to distinguish between what is a folder, and what is an external SD drive????

Anyone at all have any comment....
I think this is important for anyone who made a Nandroid backup using RzRecovery and had the external SD card as the target for storage.......
they could possibly be missing 400MB of space.....and have a dodgy folder on their internal Storage.

I don't use RZRecovery, but in your case I would connect my phone as USB-Storage to the PC and search by size all the internal and external storage.
You can also search for nandroid.

Thanx for answering.
Like you, I no longer use RzR, but I did at first....and was puzzled by the disappearing nandroid on external SD. Which is why I posted my OP.
As for connecting to PC......
I already did that, as confirmation of my findings above.
The internal storage drive did indeed have the /external_sd folder, which had in it the complete nandroid, as described.
When external SD is mounted on your device, these contents cannot be seen, as what appears under the /sdcard/external_sd will be the actual contents of the external SD.
So, this phantom nandroid and it's contents is masked to the user.

[Q] storage problem

Hey Guys,
it's me again haha.
So I have a problem...
I just read this about the memory of our phone:
Vyker said:
There are 3 storage options on this phone...
ROM aka Device Memory = 1GB = Where apps install to.
Internal SD aka USB Storage = 2GB = Extra space
External SD aka SD Card = upto 32gb microSD card.
Click to expand...
Click to collapse
So, I downloaded Backstab and need to download extra data, which are downloaded to SD...
Now I'm getting the message that there isn't enoght memory aviable.
So I looked into the file manager and saw, that all downloads,pictures etc. are saved on the "USB Storage" (→Internal SD).
Now my question is, how I can change the standard storage to "SD Card" (→External SD) , that my downloads, pictures (and of cause the data for Backstab) are saved on my "SD Card" (→External SD), where are 8GB free instead of the 72MB on "USB Storage" (→Internal SD).
Hope you understand what I mean ; my english isn't the best, I know
Thanks in Advance
Julian

I got that same problem when d/l additional data for games, etc.
Any sollution for it?

App 2 SD (move app to SD)
You can find this tool in the android market.
Note not all apps can be moved but this may help.

That app only moves apps from the Device Memory to the internal SD, not to the external one.
If your phone is rooted (if it isn't, I'd advise you too, although I reckon you should first research the pros and cons - and your warranty is voided), you can use ROM Manager to change the default path App2SD puts your apps into, or you can flash a ROM with internal/external memory swap.
Short version: both of these solutions require your phone to be rooted. If it isn't, then my post isn't of any help but there might be someone more knowledgeable out there who actually knows another (better) way to do this.

This is not true.......
App2SD moves Apps to External SD, if you have normal /etc/vold.fstab, with mount points as normal, not swapped.
This App is really just a GUI to do what you can do with native Android Apps 2 SD....and it gives Notification if a d/l App can be moved, i.e. coded by dev.
To actually see what Apps are on External SD, if you have moved them, use Storage Analyser free from Market.
See samples from my phone:

"lightbox_close": "Close",

}
You can clearly see, I hope, Apps which have been moved to External SD, in /sdcard/external_sd/.amdroid_secure.
These Apps were moved with App2SD.
Also, if you look at the pic below, of Settings/Manage applications/On SD card tab.....this shows those Apps which have been moved to External SD, which have a check-mark, e.g. Google+.....you can also see G+ above, clearly in external .android_secure folder
and it also shows those Apps which can be moved, or are coded to by dev.
btw...the USB Storage message on bottom is just information!!
USB Storage or Internal SD, is intended for Storage of Data relating to Apps, Pics, Music, Game Data, etc.
USB, or Internal SD, cannot be used, normally, for Apps, i.e. as in App2SD

I see. I was wrong then. Thank you for the useful post. It turns out I was fooled by the "USB Storage" bar, since it seems to imply they're stored in the internal memory.
But I don't think that'll really solve his problem, as from what I understood, the application data is still stored in the internal SD. So I still think the internal/external swap would be the best solution for him. Specially since he also complains about the pictures and stuff.
Either way, that ended up being an important piece of info for myself, so I thank you again for correcting me.

Thanx Dusk252
You are correct re OP......
if you wish to store loads a game data or photo stuff....
I think that is what the swap was designed for....it will give you potentially 16/32G for this data....I feel you will need a good SD....like at least Class 6....
And Apps can be moved to the smaller Internal SD....which could be good.....
On my last device I needed to use DT's A2SD..with 1G ext-3 partition on SD for Apps.....so this phone is pretty good.....
Just on the OP....it is a pity that most Apps seem to be written with the /mnt/sdcard as default external Storage....
something devs should keep in mind!!!

Hey Guys,
thanks for careing about my problem
But I don't understand how I can swap the internal/external :S
could you please explain it to me.
Thanks in advance
JuLiian.

You have too ways of doing that (technically, three). But please understand before trying any of this that your phone must be rooted!
1. Manually edit the /etc/vold.fstab file (non-recommended unless you can find a good tutorial specifically for Galaxy W, since different devices might have different mount points. I wasn't able to find one, but my research took me 2 min so you might be able to find one.)
2. Replace your vold.fstab file with an already edited one. Here's a nice tutorial on how to do it.
3. Flash a custom ROM which already has this tweak. Like this one, for example.

backstab is gameloft ryt? y not try this http://forum.xda-developers.com/showthread.php?t=1091455 it work on asphalt adrenaline and dungeon hunter, what it does is it changes the file path of the data, so that your data can be save on your external_sd, just follow the steps there, hope that helps
edit: ow sorry that link is for LG but i find one for samsung like: "Auto_Patch_APK_for_Samsung_by_Duero__include_Java_" just search for it

1. If you want to install apps on the sd card you can create a partition in your sd card which will be treated like internal memory. Check this out http://forum.xda-developers.com/showthread.php?t=1397120
2. RAM is a completly diffrent thing, you can't increase it, it is the temporary memory and it doesn't act like the normal memory, you can equivilate this to your pc, the numer of programs you can keep running at the same time is set by your RAM but sd card memory is what you refer to as hard disk memory.

I have installed link2sd card through whch I am able to store apps to my sd card but they are still storing app data to internal memory.
Can I move that app data to external card? so that it will release more space and I will able to story more apps.

When creating the link make sure to check "Link lib files", this will link data too.

It asks you this if you do it manually, otherwise ther is an option in settings wich allows you to choose what it will link. So there check "Link lib files".

How big the second partition should be so it is enough to link all your apps?

SD card corruption issue on Lineage OS 14.1 on Harpia Moto G4 Play XT1602

It's been a while since I had been using Lineage OS on my Moto G4 Play and apart from losing VoLTE, everything seemed to work fine EXCEPT my external SD card. On my stock ROM, i had my Sandisk 32 GB Class 10 card formatted as internal storage and it worked flawlessly.
I did the same in Lineage OS but everytime, after a month or even few weeks, the SD card gets permanently corrupted. First time it happened, I thought it was the SD card issue, got a brand new one on RMA. Happened the second time, again got a new one and this is the third time it has happened. I find it really hard to believe that cards which were brand new got totally fried up 3 times as a coincidence or fate.
I think, there is either some problem with the OS itself or the phone. XDA folks, help me out. I feel ashamed sending the card for a third RMA.

To my experience we have better stability when using SD as portable storage. And it's easier to repair using a PC.

The solution I found is.
1- have rooted phone 2- enable usb debugging 3- format sd card from Android options as portable . 4- format sdcard as fat32 or ext4. (Fat32 preferably- most recommended) 5) Check sdcard current format with app called disk info . Avoid NTFS format ( this could be the reason it's not formatting as internal storage, Android doesn't support NTFS as internal , and works bad with it as portable) Inside the app check the path of your sdcard.
Download app2sd from somewhere.
use the Partition tool ( as adoptable) inside to create 2nd partitions as vext4
Choose adoptable option and create 2nd Partition as ext4 ( it will actually create a virtual ext4 partition)
choose how much size in each Partition Partition 1 will be internal . Partiion 2 will be external.
So give more than 50% size to 1st Partition this way you might avoid more problems
Press create, you're done.
This method persists for me after reboots.
Thank me from your prayers if it helps.
Details --> go check storage & usb or use disk info to see your new expanded storage size with your new unmounted virtual disk and smile. This new Partition can only use installed apps, but you can't browse it's contents through your Android usb & storage options ( since it's virtual and we're tricking the fuse encryption config) If you actually want to browse this new virtual internal Partition and access it's contents you will have to see the path through disk info APK and access it with root file manager like Total Commander.
Also Do a chkdsk /f from Windows on the sdcard or chkdsk /r to see if the problem is the sdcard or try it in another Android Phone as internal. If it doesn't work in other phones then you know it's the card malfunctioning and not the phone.
This is the dumb error preventing you/us from having persistent storage.

This is how it looks after applying solution.
That phone came with 16gb storage. Now I added 16gb more with this method , for 32gb total
- Partition 1 with 13gb as virtual internal and Partition 2 as portable with 3 gb remaining. (The virtual Partition cannot be seen, it says 3gb/16gb when actually it should say 0gb/13gb) It's cause I managed to bypassed this encryption
