hi, i have a sandisk 512MB Pro Dua memory card i use in my phone.

 

i have never had a problem with this. i just put it in the usb card adapter then it comes up.....

 

now i have a 4GB sony card. this doesnt come up when plugged in. it sometimes come up if i have it in and do a full reboot.

 

the 512 come up as 'system:/media/sdb1' or media/disk

 

i hate to say this but in desperation i used winxp.... i feel sick

it worked fine here swapping quite happily, so...... im back using windoze just to put stuff on my memory card?

 

 

can anybody help?

:wall:

Noticed only the other day that sometimes 4GB USB sticks cause problems, and it's not necessarily related to Linux, also happens in Windows. I hear they require special software? :unsure:

I don't think the filesystem has something to do... and if you format the "big" one as FAT16 you have to create two partitions (2 GB is the size limit for FAT16). You can also format it as NTFS and use ntfs-3g, but IMO NTFS on a pendrive is an overkill.

Do you have "dosfstools" package installed?

urpmq dosfstools

I don't have a 4GB pendrive to check Ian's tip (mine is 2GB), but I do have a 4GB memory card on my Sony digicam, formatted as FAT32, and I can mount it just fine... either with digikam/ptp or via konqueror/usb_storage. So, if the above is happening, it must be random...

yes i do have dosfstools installed?

 

im still at a loss. ive reformatted my card and as you said cant have one partition on a 4GB card unless fat32

 

 

i cleared the card and allowed the phones internal auto formatting to take place and it does it as fat32

 

so as it is im flitting between xp and linux just for my memcard?

 

all help is much appreciated......

No need to switch to windows to use memcard but i will give you an advise based on my problems with usb sticks.

 

Reboot into windows and format the card with default values,meaning,dont touch in any settings in the windows gui to format the card.

 

Works like a charm for me and it is the only way i could find to put usb stick/memcard to work in windows and linux.

The card would be formated as fat32 with 4 Gb file limit size...seems enough dont you?

If i format any card/usb stick i have in linux,linux always recognise the drive but windows not.....weird :wall:

 

Cheers....
