Inconsistent trouble with SD card writing - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I bought a SanDisk 8GB class 2 micro SDHC card and I noticed that
it behaves strangely in the SG.
When writing larger amounts of data (100s of MBs) I get write errors.
When eg copying from internal SD (/sdcard) to external (/sdcard/sd) with
a filemanager or a backup program.
When connected with USB to a Win7 computer I can verify the disk or do a low level format, no problems. When I copy large amounts of data however, the SG hangs and I must reboot it.
When I put the card in an adapter and mount it on a Win7 or Linux system then I can hammer it with data transfers and all goes well.
So it is SG related and I'm using the stock firmware.
Bad contacts in the SG are unlikely, because once the data is written in the adapter it can be read without issues in the SG and the same contacts are used for writing and reading.
Looks like a driver problem to me.
Anyone else had these kinds of problems?

I have exactly the same problem with a sandisk 4gb class 2. I did not find a solution yet

I have that problem. I believe its got to do with how much power the sgs drains from usb port. I fixed my problem with a powered usb hub. So try that, it fixed alot of usb connection porblems too.

I have the same problems on SG 3

Cannot Read 8gb micro sdhc card on pc

my computer sees this as an external drive but still says insert disk in drive d? some colleagfues say the pc cannot read that size of the card and requires a bios update????? any ideas what they are talking about and how i fix this problem
Thanks in advance
Hi tubzy,
I'm new to this topic, but I think you'll need a SDHC compatible card reader.
In the linked thread is a solution I think.

no solution still
hi eda-one
sorry this still is no soluton - i do hae the latest sandisk with the card reader and once all this gear is connected to the pc it says...please insert a disk in drive f??
even though the disk is in the usb card reader
did you try format it?
If you have used the card on an 'oldish' PC without the latest BIOS or Windows updates installed it may not be SDHC compatible even using a card reader.
You can also get a situation where formatting using the standard Windows formatter or even just writing files to it from your PC will corrupt its filing system.
There are various utilities available on SD manfacturers sites for formatting and recovery.
Check out the 'Formatting and Read/Write check util in the OEM section here and download the latest drivers for your reader whilst there.

Hope this helps.
Hi and thank you
HI
Even after trying this it still doe s not work,
I have downloaded the utility and attempted to run it but it says no usb found even though it can vonnect to a usb pen drive?? any ideas ??
thank you
I had that same problem when I first got my 4 Gb SDHC card and it was because I didn't connect the card reader directly to a USB port, instead I was using an external USB port. When I put it in to an onboard one, even though all of mine are on the back of my computer, it started working.
8gb card
Hi and thanks for your response.
i am sorry but can you please clarify what you mean to be onboard usb port. Is this the sockets where you normally connect any usb device eg a mouse to a computer or do you mean i have to take the computer apart and do it a motherboard level?
I am not very technical and apologise in advance if it sounds a silly question.
I bought the damn thing and was hoping it would and should work from out of the cardboard package. I can see this on the my computer as an external drive but when clcikcing on it it says insert disk
if the disk was faulty it would not work on the phone but on the phone it says 7.5 gb available and have stored some data there. So i think it it is a case of the pc not being able to read the card and from there i dont know what the problem is.
Any further light on this subject would really be appreciated

You have it right about what I meant. I did mean the sockets where you connect any USB device. You don't need to take your computer apart or anything. If that's what you are already doing then it's possible that the reader that you got with the card may just be faulty.
Not knowing what adapter you are using is a problem. I had similar problems with my first SDHC card and finally went to a local office supply store (Staples) and bought a "Sandisk MobileMate+ USB Memory Card Reader" for $15. It is a memory stick sized device and it accepts the SDHC MicroSD cards directly in it's slot. This works great on any PC so far.
It just may be the reader.
thanks!
This is a nightmare on elm street scenario.
I have finally tracked it to a faulty card reader, so i purchased another one. This one works and we have another problem - cannot copy data file path is too deep???????????
I am openeing another thread for that
Thanks to every1 for trying various solutions
I'm guessing you got a bad card..which is going to happen a lot with these high-cap cards, at least for a while. I am assuming you are using the small, plastic USB reader that came with the 8 gb card....that plugs directly into a USB socket? If not...I can tell you right now..the "older" adapters will NOT work with 4/6/8 gb cards. By this, i mean the adapter/reader that usually comes with the cards in the package. Also, it may sound silly..but make SURE you didnt, or are not, forcing the card into the phone/reader backwards...i know it's silly, but it's damn easy to do..and it usually trashes the card. My 8 gb just got in tonight...and it's working like a champ. I'm guessing you got a bad card. best of luck.
This is crazy. My phone reads the card just fine, but the card readers I have do not work period. 8G SDHC

Speed of SD slot?

I am upgrading from XDA Exec to the Vario III and I was going to buy a memory card at the same time. Does anybody know which class the SD slot is? I am hoping it is nice and fast and supports the ultr high speed cards.
Thanks
Allan
I have a cheap card that I got with the phone and a more expensive one (Sandisk UltraII)
Personally, with the Kaiser, I can't tell any difference between the two. Not when transferring files to/from my computer and not when using the actual device.
However if I compare the two cards in my cardreader on my computer there is a world of difference. (The UltraII being roughly 6 times as fast as the generic one I got with the phone.)
I don't know if it's just my phone or ROM but to me it doesn't seem as if the Kaiser can actually utilize the extra speed at all.
Of course, the Kaiser having an utterly slow USB connection doesn't really help either so maybe there is a difference when it comes to usage on the actual device. If so I just haven't noticed yet as the only transfer heavy stuff I do if pushing files to and from my computer which (I guess) might be hempered by the USB connection.
I'm using Kingston microSDHC class 4 card and in phone it is just so slow as generic ones, but in USB reader it's fast like hell

[Q] USB write problem

Hi,
I am having problems with writing files SD card mounted as drive on HTC Velocity.
The phone often but randomly loses connection but only when copying large amounts of data. (mostly lots of small files)
Both SD card and Internal phone memory drives are lost.
I need to unplug/replug usb cable to restore drive.
When copying files, they randomly pause for a few seconds at different point and then continue then suddenly drive is lost. It appears as though HTC velocity has some other process running that interferes with copy process.
I have tried:
copying from different PC using different USB cables.
Tested SD card in SD card reader directly plugged into PC.
The SD card is Adata 32G UHS.
Any ideas on what more I can do to troubleshoot this?
Are there log files on phone that I can view?
Thanks

Could be a problem with the micro usb port on the phone. Check for any dust or debri or any bent pins.
I don't believe it is physical - read is ok
Write to internal storage is ok as well.
I have checked pins and all looks ok.
Also swapped with 16G SD card that was working in HD2 - same issue.
Still having issues writing.
Is there a legacy USB mode similar to some earlier HTC models or other settings I can change?
Any other ideas please?
Thanks
Solved
Did a factory reset and seems to have resolved the issue.
Wipe all data from data/sd card.
Suspect there was something installed that was causing SD card connections to stall when writing.
If I will update if I figure out the cause

SD card issue

Dear community,
I'm expecting a problem with my SD card: I can no longer mount it on my windows pc using my usb-microusb data cable.
I tried with different ROMs and different data cables of course
The SD card seems to be oddly fine. My phone recognizes it and my notebook SD card slot as well. I performed a check disk via Windows 7 and everything seems to be just fine. The charger seems to be working as usual. The only thing is that I can no longer see the proper notification when I plug the phone to the notebook.
Does anyone know what wrong with my device?
Thank you in advance for your help. Cheers, Aldo.

[Q] i9001 Writecache

Copying something via USB Cable from the PC to my External Class 10 16gb card is excruciatingly slow, under 1Mb/s. Copying from the card is reaching 8Mb/s or more. I figure windows 7's Writecacheing is to blame, anyone know how i could disable this? Windows says that it can't due to some setting within the device...
On a side note i am using the latest CM9 from Arco...
