My arc cannot recognize formatted SD cards, help? - Xperia Arc Q&A, Help & Troubleshooting

I've tested two sandisk class 4 SD cards.
If I format it to fat32 and partition the space(to use link2SD), my phone refuses to use the SD card and says it's not there. I use minitools for partition and the official SD card maker software for formating. I did everything by the book and tried multiple options(different labels, ntfs, ext2, etc.)
A fresh, unallocated space card works perfectly fine however.
My phone is rooted and unlocked bootloader running softMIUI rom with a modfied power saving blend kernel.
Please help! This is confusing the hell out of me.

Was looking at your post and I decided to grab a few of my MicroSD card 1gb, 2gb, 4gb, 8gb and 16gb....
I formated all of them on windows .... right click format, all default settings... Fat32. These are MicroSD cards that have had information on them... they all run fin on my arc. All different brands.
This leads me to believe that there's possibly either something wrong with the MsD card or the reader on the phone.

Solved it
Did this:
Changed the partition id to this:
"0*06 fat16,greater than 32 mb"
and made the second partition fat32 as well.
Removed the 100mb linux swap file partition I created....not sure if that was necessary.

2gb cards wont regonize

Greetz people!
My problem is that my Herm200 wont regonize 2gb micro sd cards. Ive tried with SanDisk 2gb (not ultraII) and Kingston 2gb card. I use my Kingston 1gb card with no problems and have tried Kingston 512mb card also with no problems.
Ive tried formatting with fat and fat32.
Any ideas?
And im running Schap's 3.57a rom, wich is a great rom by the way. I tried the SanDisk card with other roms too, so i dont think the problem is related to the rom.
Dumb questions first - can a PC card reader access the card? If so, what filesystem is the card formatted in? Can't remember what it needs to be (FAT or FAT32) but if the PC can read it, format it to each until the phone can read it.
Yes card reader can read both of the 2gb card's (i have them both here) and i have tried fat and fat32 systems.
Strange since the Newer ROMs support 4GB cards the only thing I can think of is try playing with the card while its in pushing it agenst the contacts or pop the battery out and push the contacts down a little so it makes the card fit snug. I have no problems and never had with my 2GB scandisk SD card. also search the threads there was lots of reported problems before with SD cards but most of that was fixed with the new ROMs

Help!, I can't partition my empty Micro SDHC card!

Hi forum!
I've tried the Galaxy S lag fix and it worked perfect, but when i wanted to try out the fix with the ext4 file system i suddenly can't create partitions on my SD card anymore.
I'm using Paragon Partition Magic 11, and i can see and delete the partition on my the SD card, the data is now shown as 16gb unallocated, but when i try to create new partitions i get a strange error:
The disk already contains four primary partitions. Basic hard disks can contain only four primary partitions, including extended ones.
Click to expand...
Click to collapse
But i deleted all the partitions in Paragon?!
Windows Disk Manager can't delete or format the partition.
I'm using a Kingston 16gb class 10 Micro SDHC card, but i have also tried with an older Nokia 1gb Micro SDHC card with the same error.
Hope somebody can help...
I've made a discovery of my own...
It seems that even though Paragon deletes the partition on my SD card, it's not really gone.
After deleting the partition "successfully", i take the card out and put it in again... Paragon still sees a 16gb Fat32 Partition.
Windows Disk Management can also see a 16gb Partition, but it can't delete it.
Any suggestions?
I can't even format the SD Card

[Q] Ext3 on 16gb SD Card

Hello.
I have bought a new SD Card (kingston 16gb Class4).
I had a lot of problems with ext3 make. By Gparted it have errors.
I have readed this topic.
Can I repair my SD Card?
Sry for my english.
How are you connecting the card? Via a card reader or still in the phone? If it's still in the phone make sure you are in recovery and not booted in to android.
I made it by card reader. Formatting and partitioning by recovery - errors.
Have you tried erasing all the partitions and creating them again? What happens if you click the 'Repair' button?
I've always done my partitioning with my card in the phone, connected to my PC while in recovery and used Minitool Partition Wizard for Windows (this software was suggested in a thread I read a while ago) and never had any problems.
There is also the possibility of the card having a hardware problem, so you might need to swap it under warranty.
yes, first i have erased all partitions (deleted)
On repair ext - error, fat32 works fine.
first make an extended partition for your fat32 and inside that a primary fat32.
The unallocated space make it ext3

shouldn't both partitions be primary (no extended ones)?
erase everything 1st keep it unformatted then create fat32 primary then ext primary (optional linuxs swap) this is what i have done when installed miui rom data2ext
i suggest you dont use that card reader try through the cell....
I have tried a lot of methods - ext still no works.

Where did you get the card from?
Stupid question but two of my friends bought cheap (fake) cards from eBay and both had problems with them, either the card kept losing data or they go errors loading from the card due to the poor quality. In which case you need to spend a little more and get a proper card from amazon on a high street retailer.
If not then as suggested use try formatting and partitioning the card through the recovery on your phone, most of the up-to-date recoveries can do this and it's the easiest way to get the card ass needed for a2sd etc. if it still doesn't work then take the card back it's probably faulty.
I bought this card too and even though I had no issues formatting the card I do have speed issues with it. I've been in contact with Kingston and they're looking into it. My writing speed is 1.6Mb/s....
But now a tip for you, I couldn't use Gparted since it's Live CD wont start my monitors. So I downloaded Easeus Partition Master. Very easy to use and it worked perfect.
Start with your Fat32 partition and then your Ext partition.
You can find the program here: http://download.cnet.com/Easeus-Partition-Master-Home-Edition/3000-2248_4-10863346.html

[Q] Help with EasyUS Partition Master?

I am trying to convert my 64gb micro SDHC card to FAT32 but i really dont wanna mess it up. when i go to format it, it asks for a cluster size, what is that??
Mine came formatted as exFAT and I decided to use it that way. It works in the phone but the recoveries will not read it.
You might try SD Formatter. It is specifically designed to format SD cards and others have reported using it to format 64GB cards.

[Q] 32gb sd card issues. Missing files after partitioning 2nd ext.

Ok so. At first I thought it was the 32gb card I bought on ebay so I just returned it and bought another class 10 32gb adata card from another seller. This time I did a surface scan and chkdsk ahead of time to make sure everything checked out before I started using it. So as one partition as fat32, everything works fine, md5's verify successfully for nandroids after backing them up to external sd. Until I go to partition the sd card for fat32, and ext4, ext3, fat32 (tried every format). Tried mini partition, easus and Gparted outside of windows. Minitool shows it as "other" format when I try to partition the second ext4 partition. (which is odd)
After I do that, the fat32 begins to not show files that are copied to it. I noticed this while doing a routine nandroid through recovery, then when checking the cwmr folder on the external 32gb card, the files aren't there. NOW after reformatting and testing again, I'm getting the nandroids to show up, but the md5 verification fails.
I'm not sure on what the issue is. I just want to have a damn ext4 partition for mounts2sd.
Is there *anything* I can do further to verify if the card is in fact faulty aside from a surface scan test? Or is that sufficient?
Could it be my phone's sd card reader?
Could the kernel's "usb fast charge" enabled cause an issue?
I'm on the stock latest tmobile-samsung firmware, rooted.
Using stable kernel:
[KERNEL][3.0.90][Tiberius 4.1.2 T989UVMC6][Hercules]
Just to be sure I understand this correctly you want 2 partitions on an SD card? I would not recommend this personally as SD cards are not really designed for that...
But I could be misunderstanding you...

Yeah, so I can have a script for mounts2sd use the ext4 partition to install apps to.
However, I'm looking for the sure fire way to test your SD to see if it's faulty or not. Is a surface scan test enough? Is there more?
I guess it's gotta be the card.. Just thought it was odd that it happened with two brand new 32gb sd cards from separate sellers.
Just put in my 8gb and everything works fine, md5's match and everything...
Oh well, return time!
