    Some user experienced SD removed unexpectly after updating there phone so i made this thread. Commonly problem ito sa Galaxy Y.


    1. ROOT your phone

    2. Install and open Root Explorer

    3. Edit files in the folder/ sys/devices/virtual/bdi/179: 0/read_ahead_kb by pressing and holding the read_ahead_kb then choose open in text editor.

    note: Other phones don't have 179:0.. but is ok 179:8

    4. Replace the numbers in it from the default (128KB) to 1024 / 2048 / 4096 (according to taste max = 4096) and then save and exit.

    3. read_ahead_kb Navigate the file again and select the permissions or hide tick marks on the User -> Write.

    Hi andre,,

    Sadly i've done the steps you gave here.. but after saving it,, the file read_ahead_kb keeps on changing back to 128kb by itself. and the error keeps coming back.

    effective ba syo yang steps andre? Any tips?

    -rooted Samsung galaxy Y
    -used root explorer as you instructed. Edited the "read_ahead_kb" with 1024 and then i save and exits.
    -navigated again on the file "read_ahead_kb" and choose permission and i uncheck the box - "write".
    then i exit the root explorer. After sometime when my fone auto locks when i open the lock screen the error notification is back again. >.<

    I'll try SD Card Speed Boost (1.0).apk hope it will work.. T_T

    Reformatting to FAT32 doesn't solve the problem for me.

    turn off phone when it is totally off

    press the volume up + the square button + open botton
    then choose wipe cache partition and wipe data/factory reset

    backup your messages, contacts, all applications and games before doing this because this will make the phone like brand new.

    Before mentioning this you should warn the members that factory reset will erase everything
    I.e. messages, contacts, all applications and games and make the phone as new it was.

    Latest firmware update available in Kies for Indian users, DDKK1, Kernel version, Build # GINGERBREAD.DDKK1.

    I updated yesterday almost 24 hours now, now I am not having the problem of "SD card removed unexpectedly" after that update. Though we have to watch for some more time and hope this is a solution to the problem.

    there is only one solution 4 the SD card problem.... just go to samsung service center and explain them the problem... they will do boot format and update the firmware.....
    mostly this problem occurs if u update ur mobile with the speed less than 10mbps....so its better to get update from samsung service center... and its 100% free of cost till 1 year from the purchase date.

    What I would suggest is to try downloading sd booster app if you have rooted your phone and set the cache value to 2024 or something that works best for you I have used 2024 and have yet not seen this problem again so hope it works for you all also. I also don't know if increasing sd cache limit has helped me get rid of this problem our something else so really can't say if it will work for you'll. Do let me know if it works .
