Connecting a mobile phone to eCS?

I have become an ovner of Nokia E51. The phone runs Symbian S60 v. 9.2. Among others, the phone contains a SD memory card which should be reachable by a computer using USB connection (the cable is sold with the phone). There are two USB regimes used by the phone, one of them is a "plain data transfer" when the SD card pretends to be an ordinary mass storage device. The device is FAT16 or FAT32 (I have a FAT16 formatted card).
Winblows reach the card immediately, how else. Apple is able to read the card but not too well (wrong card capacity). eCS detects the card, mounts it as a drive but it is completely unable to operate it.
If I attach the card and run DFSee, I get a warning about "large floppy device" but the card seems to be detected well: capacity is okay, format is FAT16, sector is 512 B as it should be. Except the warning about large floppy device, no errors are reported. But the card has no drive letter even if it should be "drive G:".
What am I doing wrong? What driver I need to access the card? Is there such driver at all? Has someone more experience?

I had to format my E50 under Windows to FAT32. After that it was recognized by OS/2. However, transfer speed is pretty slow...

Hi,

I'm having a Panasonic X800 that runs Smybian S60.
As I have not tried to use it in either other way (USB / card reader) with eCS, I can't tell much about it. I mostly sync it via Bluetooth under windblows... but as I don't have a card reader in any of the machines that run some OS/2 flavor, I could only ask you for patience regarding giving it a try.

I'm not sure how it behaves when using the USB cable. Will try that over the weekend.
I'm pretty sure it should be aesier to put the SD card (w/ adapter if needed) into a card reader to overcome possible pitfalls introduced by the phone's "wrapping" around USB protocols (if these exist). Then again, if you manage to "see" the card but are unable to access it... perhaps it "only" needs to get the LVM info onto it to make eCS able to handle it? Isn't that something like the problems people have with large USB sticks?

-will keep you in the loop anyway-

regards,
Thomas

Thanks you both. I will check the LVM info - supposing I'll be able to access the card from DFSee ;D So far, I only know that I can check the card by DFSee. I didn't dare to manipulate the card because I am completely new in connecting phones to computers ;D
The card isn't big (256 MB). It's a "micro SD" card but I have an adapter (also sold with the phone) to the normal SD card size. Nevertheless, this means getting the card out of the phone. A simpler solutiuon seems to be FAT32.IFS and FAT32 format.
If I understand well then the card should not contain something that must not be lost. In the worst case, I can connect the phone to winblows and format the card from winblows. Am I right?

If your phone is new, probably not. Otherwise you might have copied contacts, music
or pictures to the card.

Yes. If the card is messed up so badly that is no longer recognized by the phone, it
will ask you to reformat it. But at least my E50 will use FAT16 in this case exclusively.

Not knowing about that particular phone, I can say the safest way regardless is to format the card in your phone... with windows being the next safest way. My particular phones (Palm Treo 650 and 680 both) would lose or corrupt data on the card if I formatted it in Windows (using FAT32). Once I formatted it on the phone (which seems to also format it to FAT32 - or so Windows tells me), I had no problems using it on either the phone or Windows.

I am not sure what the difference in the format method is - but there was definitely something different, and others on the Palm forums indicated the same problems and solution.

So... I dont know if that applies to you - but regardless, it is still probably safer to use the phone to format a card (if it has that function) since it should know exactly how it needs the filesystem laid out.

Hi Radek and everybody,
I am more or less in the same situation: I have just bought a second-hand Samsung SGH-E900, and I put a 2Gb micro-SD into it. The card has been formatted by the phone, and Windoze tells me it is FAT32.

OS/2 recognizes the phone with the card in it as a mass-storage device, and mounts it as a normal USB drive, but then can't access it.

DFSee recognizes the drive with the correct capacity, and confirms it is FAT32. If I try to use DFSee to change something on the card (e.g. add LVM info) it operates as if everything was correct, but nothing really happens. It seems DFSee is not really writing on the device.

It's a shame... it would really be nice to be able to use the card from OS/2.

Bye

Chris, have you tried doing all the LVM fixes and what-not from DFSEE under windows to ensure that it actually writes, then try to see if OS/2 is indeed mounting it correctly? The phone may not be pure UMS/MSC compliant.

Robert Deed

This is similar to what happens when you try to mount and ipod in OS/2 =)  except in the case of the ipod LVM trashes the filesystem =)
