QSTN1: Is it necessary to umount sdcard1 before running fsck_msdos?
By doing so seems to break and remove some HomeScreen icons on some OS's where certain Apps have been 'Moved to SDcard'.
QSTN2: Does newer versions of Android OS (ie 5.0.2+) natively and automatically run fsck and fsck_msdos at boot-time on your FAT formatted plugin micro-SD card, or is it an add-on specific from various OEMs?
Most of you are probably very familiar with Windows ChkDsk.exe C: /f to repair damaged/corrupted SDcards.
You may have found that by removing your SDcard from your Android device and running ChkDsk under Windows, that you solved a lag problem with your Android device. By running ChkDsk on your SDcard, maybe prompted for you to 'Convert lost chains to files', and by fixing that, fixed my lag problem.
You may also have found that sometimes that's not enough, and you need to copy your whole SDcard over to a Windows folder, reformat your SDcard as FAT (same as it was before) and copied your data back. That certainly has been the case on one of my older and slower Android 10" tablets that some Apps like 'Screenshot Ultimate Pro' by 'Ice Cold Apps', as great as it is, sometimes corrupts my SDcard when I'm tapping around too fast.
Instead of having to take the SDcard out of my tablet each time I detected this problem, I needed to run fsck_msdos on the tablet itself, so I went through the motions and finally created a HomeScreen icon, where one single click will repair the SDcard and I could then get on with business.
TIP1: I've successfully created a HomeScreen icon using SManager by devwom by placing the following script under a 'scripts' folder I created under the default Home directory of SManager.
I also made sure that the script file had the appropriate (FULL) rights and that under Advanced, I made my 'Scripts' folder, SManager's Home-base.
My preferred location to place shell (.sh) scripts for SManager (Script Manager) by devwom:
/data/data/os.tools.scriptmanager/Scripts/
I used SMWidgets by devwom to create the HomeScreen icon for the script.
#!/system/bin/sh
# scr_FsCk_MsDos_on_MoXT1068_sdcard1.sh
# umount /dev/block/vold/179:65
fsck_msdos -y /dev/block/vold/179:65
echo .........
echo : Done! :
echo .........
NOTE: You can see in the script above, that I've commented out the umount command which seems to work whether or not the SDcard has been dismounted or not.
This is my main question I need answering, as around the traps, I see conflicting reports about dismounting first and I'd rather not have to do that if all works by leaving the SDcard mounted during fsck_msdos.
Thanks.
