can not write to usb stick, only read

i mounted my usb stick as rw but everytime i try to write to it, it gives me the error,
- Error "Read only file system" creating new folder.

i used to be able to write to a few weeks ago but now i can't.

i mounted it onto /dev/sda4

when i mount it onto /dev/sda
all files with strange filenames come up, like it's corrupt.

i've tried puting all kinds of options in /etc/fstab but still is the same.

/dev/sda4 /mnt/drives/usb_stick vfat rw,user,noauto,umask=000 0 0

the only thing i think it might be is that because i used it on windows, windows did something to it so i can't write to it now.

i wouldnt think that windows would do anything to it to make it not writable...i use usb drives with win and lin all the time without issues...but you might check it to make sure that it isnt corrupt using:

fdisk <device>

and it wouldnt happen to be formatted as NTFS? (although im not too sure that you can even do that in windows)

and just asking, but do you really have 4 partitions on a usb stick?! (i noticed the /dev/sda4)

It sounds like the filesystem is corrupt and so it is being mounted read-only as a precaution. You could unmount it and use the fsck.vfat command to repair it. Since you are using windows as well, you can try repairing it in windows as well.
