SD card problem (so slow) - JAMin, XDA Neo, S200 General

Hi everybody,
I have a problem with my sd card.
I have a 4Gb transcend 150x card in my G4 prophet (s200) and reading is so slow.
Here i post a benchmark done by sktools:
Storage Card (write) : 31.75 Kb/sec
Storage Card (read) : 798.18 Kb/sec
I think reading time is so slow.
I have spanish qtek rom 2.20 and test was done using sktools 3.1.1
I have formated the sd in fat32 using computer sd card reader, but nothing goes better.
Any ideas on how to fix it?
Thanks in advance.

umm this is just a thought but have you checked the partition?
thats usually the end of most problems regarding SD cards.

What do you mean whith checking the partition?
I have formated the card twice one with panasonic formater
Best.

no check and rebuild the partition, formatting wont do much if the partition is corupted.
get something called Partition manager you can get a demo version that will do it. use your card reader and delete the active partition (remember to get your info off it first) then reinstall the partition format and mount the card.
see if that helps

Thanks very much, it seems that partition is ok and i also tried another memory card with the same results.
Could you please do the same test and tell me your results, rom version and memory brand and size.
Best.

Toshiba / Kingston 512M SD has compatible problem with XDA2?

My Kingston 512M SD (toshiba OEM) seems not compatible with XDA2.
The writing speed is slow (compare to lexar), and the machine always can't read the data on the SD. Sometimes the data on the card became read only. However the card works perfectly on my digital cam and card read.
Anyone got a Toshiba or Kingston 512M SD can test for me?
I had the same problem w/ my new 512 Mb Kinston SD card too.
My solution was to re-format the SD card this way:
FAT
16K blocks
Don't use FAT32 as that slows things down IMHO.
YMMV
-Jim
Thanks :lol: .
It seems perform a lot better with FAT16 and 16K blocks.
I think there must a bug in the OS because O2 never test SD card above 256M.
I've got a viking 512MB SD card from www.ebuyer.co.uk and it works fine.
Can I check how it is formated?
If you got a card reader, I think you can check it in the windows.
Use the command prompt , type "chkdsk X:" (x = your card reader's drive letter) and you can see the block size and the file system of the card.

Maximun SD card size

Hi
I bought my wife an XDA II a while ago on ebay -- all works fine but....
.... it's working on a 256mb SD card.
I now have a spare 1G and 2G SD card and trying to use them --- and they will not write or format
message ranges from "write protected" to "device in use" to "write failed"
Any ideas? - are they too new? are they too big, or do I need a special format program.
Cheers
Mike
I asked qtek about the maximum SD-card size. They said 2Gb, so I bought that. It is a 150x fast card. It works fine! Would like to have a 4Gb thou!
I have had no problems with my other SD-cards either (512kb and 1Gb). (All of them had been used in cameras before, no extra formatting needed).
Thanks for your reply, I will try a soft reset and then try again
Nothing I do works.
I have even tried Panasonic SDFormatter incase it's the formatting.
All errors so far this time say that the card is write protected - but it's not
Mmmmm
I've got it ...
Checked all the messages about SD cards and one suggested a fix.
It's physical - I just need a label over the write protect switch
also remember to format teh card from your pc in a card reader, and dont format as fat32, it must be fat16 or just fat, my m1000 hates fat32 and wont let me reformat or read the card.

Corrupt SD-Card 2 Gb

hello,
i copied in the morning some folders into sdcard via.. card reader...
then i went off with the card..
on the way.. i found out.. my sd card was empty somehow..
i softresetted, nothing fixed it..
when i refresh and view all files.. i see only strange characters and strange folder names..
and the sizes all together looks like 50 GB.
but in fact the pda tells me.. there is only 1,7 GB free instead 1,9 GB..
my sd card is 150x Adata 2 GB..
how can i fix this .. please help me out.. i dun wanna reformat this card, as i have important files on it.
yup you are the proud owner of a broken partition (very common with Fat16 and mobile devices)
from expereince ive found it happens alot with Fat16 and lots and lots of files (like those found in many of the better games or if you have alot loaded onto the card)
my recomendation is to get to a card reader and get some partition management software ( i like the trial version of Partition manager) and rebuild the partition on the card.
let me know how you go,
You can try downloading PC Inspector File Recovery, and running it on the card. It's freeware, and should work well given your card is formatted with an older filesystem.

You'll likely have to reformat your card, but at least you'll get your files back. If you do have to reformat, and your device supports FAT32, please format your card in FAT32 instead. It has a higher "tolerance" against this sort of failure.

Click to expand...
Click to collapse
mmmk with a broken partition you wont have alot of luck recovering file clusters, at the very least you will recover things that look like file.001, file.002, etc as most recovery programs will recover pure clusters regardless on data.
and yes Fat 32 is good but you will still get partition faults if you load too many files onto the card.

Unable to format SD Card

Since upgrade to MCR 2.9 rom i have been unable to format my SD card. I had an 8gb class6 card formatted to fat32 when inserted says the card is blank and doesn't format the card, same with a new 2gb card.
any one got any ideas??
im still running MCR 2.8 and i seem to have the same problem. i am unable to format my sd card.
Hi,I have same problem after updated to modaco 3.1,I can unmount the sdcard,but after I click format nothing happenes,and I cannot install ra-recovery,maybe because a first problem...
Anybody know how to solve it?
Same problem here... i tried everything. im pretty sure this card is dead. It was a samsung and happened after i used iSyncr and removed it not "safely" -
Try to format the card with windows, trough your phone or, if i't not working, with another reader, like a camera or a sdcard reader.
Use this software to format it:
http://download.cnet.com/Partition-Wizard-Home-Edition/3000-2094_4-10962200.html
Do a FULL format not a quick one. After you finish, format the sd card again with android and create your ext.2 partition if necessary.
Let me know
