I HAVE SOLVED MY GALAXY Y ERROR, but before that let me tell you the solutions that I had tried that did not work for me:
The error did not occur on my original memory card but when I switch to a Kingston 8GB Class 4 the error started. My co-worker uses the same phone and switch to the same mem card and also experiencing the error since changing it.
At first i didn't mind the error but when i rooted my phone to extend my internal memory by partitioning my micro sd the problem became a big impact on linked apps on my sd card so started asking solutions to google.
Sorry for the long introduction, this what I have tried to my phone:
1) Updating my firmware - DID NOT WORK
2) resetting my phone to factory settings and formatting my sd card inside the phone - DID NOT WORK
3) Using SD-Booster and tried setting the cache to different numbers 1024, 2048 and 4096 -DID NOT WORK
There 1 option left that I have read on 1 of the forums that works
CHANGING MY MICRO SD CARD- IT WORKS (YEHEY)
someone said that TRANSCEND and SAN DISK is very much compatible for android forums so I have tried it.
I bought TRANSCEND 8GB CLASS 10 ULTIMATE - REALLY WORKS AND I ALSO TRIED PARTITIONING IT AND WORKS PERFECTLY FINE.
The conclusion here is some of the android phones are not compatible to some micro sd card.
Hope it helps
tell me if it works for you... please indicate your memory card so we can know what brand is not compatible for android phone especially Samsung Galaxy Y
