I have two usb sticks,both are recognized automatically but when I try to write or copy files to either it comes up with error saying I do not have permission to copy to this destination folder.I have changed the permissions in properties but it will not let me to change the permissions for the actual usb stick. What can I do?

EDIT: USB stick info from comments:

Solaris Disk /dev/sdb: 2065 MB, 2065694720 64 heads, 8 sectors/track, 7880 cylinders, total 4034560 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18 Device Boot Start End Blocks Id System /dev/sdb1 * 32 4034559 2017264 6

sudo fdisk -l

will tell you what's mounted. Then run:

sudo chmod 666 /dev/sdY

where sdY is the device assignment for your USB drive.That will allow you to read and write.

  • Do you know what I can do? – user172503 Jul 19 '13 at 09:36
  • Not really, nothing you posted is about a usb stick. – wojox Jul 19 '13 at 13:06
  • Hi, I am sorry but I thought it was, since I believed that what I posted was the results was the result of fdisk -l. If these are not the correct results, does this mean anything to you. /dev/sdb1 on /media/usb0 type vfat (rw,noexec,nodev,sync,noatime,nodiratime) deprima@deprima-K53U:/media/usb0/Google$ – user172503 Jul 19 '13 at 14:03
  • this doesnt work its not this simple – Philip Rego Apr 23 '20 at 19:20

Depends on how you have formated the USB drive.. often they are fat32, and if so, not that many things to setup.

if you format at extX then you and simply use chmod and chown to set permission and owner

edit: I see that from a comment above it looks like it has fat16 format. so it does not support file permissions.

see here for a way to mount it using different permissions
