First time post...
I received a Zeki Quad Core tablet for Christmas and, while I have been pleased with the performance, I am not pleased with the lack of available memory. I bought a 32Gb micro SD card which I thought would help, but apparently the way Android manages memory that wasn't the full solution. After several attempts to fix this (e.g. modify the vold file), I came across Link2SD which seemed to solve the problem. I now have quite a few apps loaded on my device, and no noticeable slowdown (I made sure the micro SD card was a class 10).
However my dilemma...more of an annoyance. The device boots up fine, but whenever it goes to sleep (either because I don't swipe the lock to open up the device, or the amount of time has elapsed with no activity), when I wake it back up, three things can happen:
-- The device works normally. This seems to be the least frequent result.
-- Several apps suddenly crash (you get the "Unfortunately" message). You still have functionality, but it's limited.
-- The black screen of death. This seems to be the most common.
I can only think that it's Link2SD contributing to what the issue is because the external SD card may not yet be activated. I do see in the upper left corner when I start the device "Preparing SD Card" or something to that effect. So I am wondering if waking the device up something is trying to access the card because Link2SD now has an app linked to it and it's not ready, causing the app to fail (and subsequently the device), or otherwise.
I can tell you that none of the system apps have been moved. I do not have the paid version of Link2SD (although I am considering it if it can remedy the problem by moving obb data or such...). If anyone has experienced similar problems, or there is a solution known, please let me know.
Thanks.
Hi there,
The best place to receive an relevant answer is to ask directly on the developer thread from here:
[APP][1.6+] Link2SD
Also please see this guides:

Is anyone running into a problem with apps that have been moved to sdcard just disappearing? Most of the time I see little green droid icons all over my launcher (ADW), and lots of missing apps in the app drawer. I can reboot several times and eventually all show up.
I'm running ee4_debloated-v421 / 0730_charge_voodoo kernel / sdcard_patch. Am on my second handset (first one had a clicky button go dead). The earlier handset occasionally did the same thing.
I presume the sdcard is the culprit, as it is the common element. But I have popped it out, run fdisk and defrag all with no errors.
Any theories??
I had this happen when I first got my charge. How I fixed it was I took the SDCard out of my phone and put it into my flash media reader, and then did a full format using HP's Format tool with default device settings. It took a long time to do the full format, but after doing so, I didn't have any more issues with apps disappearing that were installed to the SDCard.
Full format, huh... (gulp) well it's certainly worth a try! I'll report back.
Thanks,
Larry

I know when the phone first came out, there were several users with SDCard problems. I'm not sure how others fixed them, but a full format and a half hour or so fixed mine
Well, I'm disappointed to report that the problem did not disappear :-( Could it be the contents? I copied *everything* from the card before full formatting with the HP tool (which tooks hours as you said), then copied it all back. Same result... if I reboot enough times it will come up with all apps showing.
I've ordered a Class 10 card. Plan to use the HP tool on it straight away. What else would you recommend? Maybe move all the apps back to the phone? Would you start from a fresh load of the ROM?
Many thanks,
Larry

I know that DroidXcon over in the Android Central forums advises NOT to move apps over to the SDcard because of problems like you have experienced...the higher (class) speed card may help. I've noticed that on my stock class 2 card when I view a subdirectory that contains large wallpaper files using QuickPic or Gallery, the thumbnails will often "time out" and not display towards the end of the list unless I refresh the listing several times. I would assume it is for the same reason that recording video to the class 2 card will time out after a few minutes.
Good luck with the Class 10 card...keep us posted!!!
Well, the Class 10 arrived in time to try again, so formatted with HP Utility and copied all the saved files over. Same behavior.
If it's the sheer quantity of apps on the SD card and there is a timeout involved, that might explain it! Reformatting the card would effectively defrag it which would speed it up, perhaps explaining imnuts' observation. And if reading in all those apps at startup is not I/O bound but maybe CPU bound, that would explain my experience.
I'm going to try moving apps back to the phone just to see.
Wow, this is persistent. Moved all the apps from SD back to phone using TiB, which seemed to hang sometimes. Tried different access methods with no clear winner. Anyway, after a reboot, the situation was unchanged. Unreal.
So I am starting from scratch with a freshly-formatted Class10 card, a full data/cache wipe, and a new ROM: GummyChargedFE1.9.1. Haven't had a problem yet, but haven't restored anything to SD either. Proceeding cautiously.
Ok, I'm converted. GummyChargedFE1.9.1 solved this problem. Everything seems to run better. Added the V6 SuperCharger thing which tweaks minfree levels and much more, and the combination runs extremely well.
Biggest problem for me is that I'm satisfied... spent the last two years trying to get my "original" Droid to run well, then got the Charge, started over. What do I do for an encore?
Fast Boot option may be the culprit
In case anyone is following this old thread ...
I did not need to install a new ROM
CUT TO THE SOLUTION BELOW -- SEARCH FOR ////
Some (not all) of my apps moved to SD (all by Titanium Backup Pro) have begun to disappear and (sometimes) reappear without warning after I began to add and delete large Virtual Machines created in QEMU from my 16GB SanDisc class 10 microSD card on my HTC Droid Incredible running rooted stock Verizon Android Froyo 2.2.3. I know this thread is far from my phone's "home base", but from what I can tell this problem with disappearing apps located on an sdcard is NOT determined by hardware or even Android version.
I also happen to use LauncherPro by Federico Carnales instead of the built-in HTC Sense launcher. I noted elsewhere on XDA that a user had suggested that because at least some (maybe all) launchers start before the SD Card that this may be a problem, especially if changes are made to the sdcard that the launcher did not perform, or was not active during their performance by other apps such as Titanium Backup. That fits my situation, because I unmounted the SD, physically removed it to a PC, and added/deleted large VM files to save (lots) of time. No problems of this sort before I did this, so there must be some connection.
I noted that other users have tried reformatting SD, substituting different brands of SD, using newer/older SD etc. None of these reliably helped. So I skipped these options.
//// The (simple!) solution I tried that SEEMS to work (only time will tell!) is buried in the main Android Settings (accessed from the Menu button while in Home screen). Under "Applications" there is a setting "Fast Boot" that I checked long ago and forgot about (it seemed like a good thing to do at the time). The text warns "Turn off to use some Market apps" (that shows the age of my 2-yr old used phone and Android OS -- ohmygosh!-- because it refers to Market rather than Google Play Store!) Anyway, I unchecked the option and rebooted the phone.
Yes, it took a bit longer to boot (maybe a whole minute!), but after waiting about another minute ALL my home screen apps had normal icons and loaded properly. Titanium Backup Pro batch scenarios confirmed there were no apps in a forced uninstalled state (i.e. I had not done the deed, the system somehow had done it or at least rendered the apps "invisible" to Titanium, which decided they needed reinstallation).
The only odd behaviour was that auto brightness was turned off after I unchecked Fast Boot and rebooted. Going into Android Settings > Display and rechecking "auto brightness" took care of that. No other oddities or strange behaviours thus far (but it has only been about an hour).
I will report back here on this thread only (Samsung Fascinate > Fascinate Q&A > What just happend? apps on sdcard) if anything else requires reporting. Silence implies success!

Yes, I've read the threads. I've done the search.
I have an HTC Aria running liberated FR008.
It's been working brilliantly for as long as I can remember but the error popped up "Couldn't install on USB storage or SD".
There is no "smdl2tmp1.asec" file on my phone, never was that I can tell. That is not related to the problem.
Yesterday, at great expense of time, I removed everything from the 16GB SD card, reformatted it, and put it all back (about 12GB worth of data). This did not fix the problem.
One thing that may be related, I recently was running into the issue of not having enough space, so I moved the dalvik cache to SD using "a2sd cachetosd" or whaver the command is. HTC Aria having limited space for apps is a known major problem that I was trying to fix. Is this related? I don't know. I did this before it began having this new error.
Someone has to know a legit fix for this issue. There is 1.65GB of free space on my SD card and 34.48MB on the internal storage. There should be more than enough space to do updates.
What's the scoop? can someone help?
Anyone have a hint on this? My search ninja skills on the net are not giving me any answers.
Continuing the theme of one hand clapping:
I found for a couple of apps that could not update due to this problem, they happened to be apps installed on the SD. I moved them back to the phone and they updated successfully. I have not attempted to move them back to the SD.
Perhaps this data point aids in diagnosing this issue. If this proves to be a consistent pattern, then I will just apply this work around as long as I have space on the phone to move apps over one at a time and update them that way. Even though the solution to this bug doesn't seem to be at hand, perhaps this is a work around.
Ive had a weird problem the last day or so, when I reboot my device, apps mysteriously go missing. Each time I reboot, like 5 or 6 different apps disappear. This only happens to SD card apps though. This started happening a few days ago but yesterday it got alot worse AFTER I had reformatted my card. Could there be something wrong with my SD card? The apps still appear to be installed in "manage applications" but they look like "com.aac.cachemate.demo" as the name of the app, instead of "Cachemate" and etc...?
did you use link2sd ?
com....whatever in manage applications usually means, that the apk file is missing, while the application data is present
the mess as described, can be seen if your ext partition is mounted too late ...
nadlabak has some fix about it
https://github.com/nadlabak/android...mmit/e5b9b3195687e04af7a7929f8637e77e1efae9a1
but i can't remember where is part of setting the property, after checking and mounting the whole card ...

I did not, I used the standard apps2sd built into CM6. Every time I reboot, different apps are missing and then some come back that were missing the time before...They all still appear in manage applications though so they might be intact but I'm not sure if all are, they show up with the default generic android icon, and weird names. "mobi.mgeek.tunnybrowser." (Dolphin Browser) and "net.flixter.android" (Flixter) etc...The storage sizes of the missing apps appear to be different then they are supposed to be. (Maybe)
(This might have something to do with it) Yesterday for hours (before I reformatted) the phone was stuck at "Preparing SD card, checking for errors" so I went online and followed the suggestion an xda member who suggested in another thread to delete the "fsck_msdos" file from "system /bin" which disables the SD card check to see if the SD card has been properly mounted and checked. It seemed to fix my other SD card issue for the rest of the day. could this be related?
Just share my experience , when I was in 2.1 , I used link2sd , and if I boot without sdcard , all my linked apps will happen like that , I think maybe this is the same case as apps2sd . So , what I do is just uninstalled all those apps , and reinstalled some of it ( it's quite annoying to reinstall over 100 apps ) . As you said , all those apps remained as it's package name , so I'm kinda sure our case is almost the same . But when I was in 2.2 , once I booted with sdcard inserted , but after boot completed , all my user apps dissapear , yes , ALL . But anyway , after scan for sdcard problem in OR , all my apps recovered , with no force close , just like nothing happen during the last boot . So also , try to scan for sdcard problem in OR .
It says my card is mounted (about half of my sd card apps show up) but when I bring up the gallery, it says "SD card unmounted or not present." When I try to unmount it in settings, it never unmounts, I just click "unmount" and nothing happens....

It sounds like you have corruption in your sdcard filesystem. I would take your sdcard out, put it directly into a Windows PC and run chkdsk (alternately fsck.msdos on a linux PC).

Ok I will run a chkdsk when I get some time to sit down at the computer later. I think it probably is corruption.

SD card fixed with error checking in windows!! Thanks!
Fast Boot option may be the culprit
The advice about checking SD card on Windows or Linux sounds good and I will keep it in mind, but I did not need to fix this sort of problem. I am not familiar with CyanogenMod (CM) in any version, but if it has a fast boot option, read on...

Sorry for opening up old thread. My HDC Note3 clone phone having the same/similar issue. The phone have 8G ROM which partition into 2 different name, internal phone (1G) and SD card (5G). Whatever Apps that I install on the SD card will disappear from home menu every-time I re-boot using the power button. However, it it still there when the phone do their own reboot due to something
I try unchecked "Fast Boot" but disappearing act still happen. Any suggestion to resolve the issue?
I have some problems with my SD card on a THL T100s running a custom Kitkat 4.4.2 ROM.
I recently noticed that Android didn't see my SD anymore. I thought it was corrupted, so I put in on my pc and fixed file system and all. It didn't work. I tried with another SD, formatted it, but Android either didn't see the card at all, or say it was empty/corrupted. Then i booted into TWRP recovery mode to see if it was some software misconfiguration issue. TWRP saw the SD, so I rebooted and finally Android could read the card. Then something very strange started to happen. In a minute or so, my file explorer that previously could read and write on the SD, showed an empty folder instead, and no read or write operations could be performed anymore. Whenever I reboot, sometimes TWRP and/or Android can read/write on the SD card, sometimes not, and when it does it stops in a few minutes. Unmounting and remounting the SD from Settings->Memory result in a "Empty/Corrupted SD card" notification. I even hopelessly tried to wipe cache and dalvik cache (resulting in an annoying "Upgrading Android" at every boot)
I tried to logcat since boot, but honestly I spent all day long trying to figuring out what happens to no avail. I'm no expert and the logcats are huge: filtering only errors, or "sdcard1", "Volume", "Vold*" (which seemed to be related to the sdcard) didn't help me. I'm afraid it is a harware failure and that I can't do much about it.
Can anyone help me to search for the right things in logcats or has anyone else have an idea about what might happen? Any other suggestions?
I'll post a logcat if necessary but even filtering them out there are several hundreds if not thousands rows.
Thanks.
Hi
Welcome to XDA Assist.

Though ,you are pretty much right . vold service manages SD card and volumes mounted such a SD card. And most probably your hardware is failing . Or the slot can't read the card properly.
A good way is to clean the contacts with isopropyl alcohol or some other cleaner. Dab some on tissue and clean it gently. You can also use a pencil eraser to clean contacts gently.
If you have any other issues ,you can sign up on forums and post in general Q/A
http://forum.xda-developers.com/android/help
Have a good day !
Just to add to this, Google has decided to limit sd card access in KitKat and Lollipop. You can also seek an app on Google Play called Sdfix which may be resolve the issue you are having. Also contact the developers of the custom ROMs you are using to see if they incorporated the known fix in their ROMs.
Thanks for the replies. I'll try to clean the contacts though they look pretty clean to me. I know about new Android restrictions, but I have root and the right permissions set. Previously it worked indeed.
I'm sure it probably is hardware related since a few days ago I had the phone repaired due to a broken micro USB port, and now sometimes even the camera can't connect. Perhaps the phone had been mounted incorrectly. I tried to dismantle it myself, but I can't see anything strange or out of place. A little pressure near the camera seemed to solve that problem. The micro SD slot isn't anywhere near the micro USB one, so this seemed strange to me. I hope the repairman didn't solder any circuitry it shouldn't.
If I don't solve with the cleaning I'll bring the phone back to him to see if he can handle that.
Thanks again
Hi All,
I got a new S8 Plus this past Friday. Nice phone, but after spending a few days with it, it seems to have some issues.
The SD card seems to mount and unmount randomly. I have a few apps that are on my SD card and every now and then I just get the gray android generic "App Not Available" icon in place of the correct app icon. Then eventually it may show up again, or it may take a reboot to show up again.
The other thing (more annoying to me) is that the phone randomly reboots without error. No heat, no other issues that I can find, just a complete reboot. Again, there is no app that seems to do it, no excessive (or any noticiable heat at all for that matter). Just a reboot. I know it does it overnight as well because I can check the system up time, and I can also tell because I have iris scanning set up and after a reboot you have to plug in your pin number no matter what.
FYI - I called Samsung and they had me clear my cache and reboot to safe mode. Other than that, they did nothing else, said to watch it. And did not indicate anyone else was experiencing this.
Just wanted to know if anyone else is experiencing this.
Thank you!
A lot of folks are experiencing this, myself included. Try moving any apps you have put on your SD card to back to internal storage, that stopped the random reboots for me. I've removed my SD card for now, hoping a software fix is possible. If this "SD Card Monitor" app is correct my card mounts/unmounts 100+ times per day, even when sitting untouched on my desk!
