IO Error on SDcard - G Tablet Q&A, Help & Troubleshooting

Hi,
I am running VEGAN 5.1.1 custom rom + Clemsyn's v 9 kernel. The table seems to work fine when it is not in the sleep mode. But once I let it sit over night, I am not able to get the screen back anymore. I was, however, able to adb to the device. I am seeing a lot of io error in dmesg:
<3>[26759.075985] end_request: I/O error, dev mmcblk3, sector 288
<3>[26759.081599] mmcblk3: error -110 sending status comand

<3>[26759.100399] FAT: FAT read failed (blocknr 33)

Anyone has similar issue?
Thanks,

To add to this. I did repartition my internal storage. I wonder if I need to reformat the /dev/block/mmcblk3p2 using windows? I tried using the parted via CWM but I couldn't find a mkfs for fat32.

pls help..anyone expert?
btw..im using 4gb class 4..tdk brand..

thanks hoping for some coments..
Whats ur partition table? Im also on froyo xxkc1, mmc with two partition, 1st partition as fat32 and 2nd as ext2. Link2sd and darktremore a2sd works great for me. Weird that u had such problem. Maybe theres something wrong with ur partition table

i had that patition also..
i had used mini tool partition in partitioning..
can u help me determine ways wrong..as u can see on scripts id post..
I use dirty trick to enable a2sd on my ace, by using link2sd mount script. What i do is,
1 - backup with cwm incase something goes wrong (actually i need to recover two time as my ace cannot boot twice while attempting this)
2 - install link2sd from market.
3 - start link2sd. It will prompt to reboot to enable its startup script.
4 - reboot.
5 - open link2sd again, now it should work. Try to link any app to test. If it works, unlink that app.
6 - open rootexplorer, edit /system/etc/install-recovery.sh (this is the mount script generated by link2sd earlier).
7 - edit it so it looks like this:
#!/system/bin/sh
#added by link2sd
sleep 5
mount -t ext2 -o rw /dev/block/vold/179:2 /system/sd
mount -t ext2 -o rw /dev/block/mmcblk0p2 /system/sd
8 - reboot ur device manually so the second partition can be mounted on a2sd mountpoint.
9 - open terminal emulator, type:
su
a2sd install
10 - if a2sd script whining about how dangerous it is to install it while second partition is mounted, try to unmount sdcard thru system setting (and obviously dont mount it back) and repeat step no 8 again. If it goes like plan, device should automatically boot.
11 - when it successfully boot, now can use a2sd command like data2sd or cachesdreset. Also can uninstall link2sd because no need for it anymore
Sent from your phone
Btw when editing install-recovery.sh, just edit the "/system/sd" part, thats the most important because it mounts second partition to a2sd recognized mountpoint. U also can modify "sleep 5" line based on ur need. It determine how long ur device should wait before mounting second partition upon booting. Obviously 5 means five seconds
P/s: this only works with froyo, it will never ever works with gingerbread. I also wouldnt be responsible if ur device stuck on boot (happen to me twice when trying to figure out this whole thing), and thats why i said to create backup in step no 1

dude..as i said..link2sd doesnt conect too..
cnt even create link..
just want u to know also that i had been enable the ap2sd but the only prob it dowsnt detect my partition..as u can see in aps2sd cache script..
lalso link2sd cant detect my partition..
what i have frst to do?
btw how to disable aps2sd darktrmor?
When u partitioned ur sdcard, do u create both partition as primary?
Also if u install darktremore a2sd zip package via cwm, try to mount system partition first before installing it because i think it doesnt have proper mount script, resulting in breaking whole a2sd script.

See, thats what i told u earlier.. a2sd script will prompt about how dangerous it is to install it while the partition is mounted. No matter u select y or n, after that ur phone will be messed. Thats what happen to me. If that prompt appear, u should close/kill terminal, unmount sdcard via system setting and try it again.

Dont know about factory reset, maybe it deletes a2sd script, maybe not. Try to run
su
a2sd
And see what the output is. If it said cannot find that command, ur back to square one, need to start from the beginning again

nope, just use ur current installed a2sd.. no need to reinstall it. the problem it that a2sd cannot mount properly. so because now u can use link2sd, just do like what i did, use link2sd mountscript to help a2sd mount to its proper mountpoint
and because u had installed link2sd and confirmed it works, start from step 1 and obviously ignore step 2, 3, 4 and 5

Custom MTD Partitions for the Viewpad (Increase Internal Memory Size)

When looking at the partition table it looks like we can use some storage from /system and /cache to be used for the /data partition. Especially the /cache partion seems quite large.
Anyone tried modifying the MDT partions without bricking the device?

Sony tablet S 16 GB - real capacity

Hi,
My Sony tablet S 16GB does, according to settings -> storage, has this much memory:
Internal storage (USB storage) - Total space 8.92 GB
Internal storage - Total space 3.94 GB
it makes total of 12.86 GB
If I take in count trick with not multiplying Bytes with 1024 but with 1000, I come to 16 GB = 14.9 real GB (which tablet should show).
So, minimum of capacity tablet should report is 14.9 GB (which I think is a chip trick that shouldn't be used) but it shows 12.86 GB which is significantly less.
Where is the rest of the memory?
Where's the rest 3,14 GB (or at least 2.04 GB)?
You have to consider that there are some hidden mountpoints for the system. Maybe the following output of the df command clarifies something:
Filesystem Size Used Free Blksize
/dev 370M 64K 370M 4096
/configs 1M 44K 1M 2048
/mnt/asec 370M 0K 370M 4096
/mnt/obb 370M 0K 370M 4096
/system 377M 256M 121M 4096
/datapp 377M 122M 255M 4096
/data 3G 723M 3G 4096
/cache 503M 8M 495M 4096
/log 15M 13M 2M 4096
/mnt/sdcard 8G 2G 6G 4096
There is /mnt/secure/asec as well but I couldn't determine the size because I don't have root access.
When you use 8.92 GiB for 8G and 3.94 GiB for 3G, you're getting close to the 16 GB. (15551 MiB)
thank you
I see it's (probably) 16GB (ISO Giga, not computer Giga) but they locked a lot of it for system use.
Next thing I could find out is that it has dual core processor but one core is only for system update?
sony still should of gave us 16GB regardless how much goes towards the rom.

Maybe. In general, the storage number always relates to the amount of actual physical storage is included in the device. User-accessible storage is a whole different deal and liable to change.
Even my iPhone, a claimed 16GB has only 13.6 (ISO) Gig of storage available, a big drop as well. Every system since OSes and applications started taking up non-trivial amounts of storage has reported the physical storage, not the user-available.

Microsd Card Read-Only Issue: DD read-only file system

My micro sd card seems to not be working at all.
Have been googling this problem for about a good 2 weeks now.
Reason this happened: was installing a ROM on phone, and I have no idea what happened.
Weird enough though, I was listening to music randomly one night no problem. Morning after I had some blank/unsupported fiel system error on sd card.
Tried many things:
fdisk (gave bad file descriptor error)
DD (read-only file system)
Disk management in windows (shows up, but no options availble. Won't even let me format.)
Device Manager in Windows says I need to troubleshoot USB MASS Storage (Using Microsd card adapter), troubleshoot to no avail.
Diskpart in windows
ChkDsk in Windows as well

[Q] Moto E has so many Unused Memory(4GB free space)!!!

There are many unused partitions in Moto E like mnt/fuse , mnt/obb , mnt/asec which are empty all the time. Each is of almost 500 MB . that's 1500 MB staying useless. There are many partitions that are unused. here is a list of 'em.
UNUSED PARTITIONS :
/MNT/FUSE ---------- 454MB
/MNT/OBB ----------- 454 MB
/MNT/ASEC ---------- 454 MB
/DEV ------------ 454 MB (128 kb USED)
/SYS/FS/CGROUP ------- 454 MB (12 kb USED)
/cache ------------ 447 MB (11 MB used)
/firmware ---------- 62.4 MB (43 MB USED)
/STORAGE/EMULATED ------ 456 MB (0 Bytes USED).
ANYONE WHO KNOWS CAN SHARE THEIR THOUGHTS AND OPINIONS !! THAT"S ALMOST 3-4 GB unused !!
Unfortunately, it's likely that many of those don't represent "real" memory. /dev and /sys in particular are virtual partitions. I'm guessing that the ones under /mnt are as well. I'm pretty sure /cache, /firmware, and /storage represent actual physical memory though.
