Hello, I have the same problem (referring to the original post) under 12.04 LTS with Nautilus 3.4.2 and a 2GB Kingston USB stick.
Copying via console and thunar (which I installed for testing) went fine. dmesg shows nothing strange, i.e. [18395.837494] usb 2-1.2: new high-speed USB device number 11 using ehci_hcd [18395.933263] scsi14 : usb-storage 2-1.2:1.0 [18396.932891] scsi 14:0:0:0: Direct-Access Kingston DataTraveler 2.0 PMAP PQ: 0 ANSI: 0 CCS [18396.934224] sd 14:0:0:0: Attached scsi generic sg2 type 0 [18397.773851] sd 14:0:0:0: [sdb] 4030464 512-byte logical blocks: (2.06 GB/1.92 GiB) [18397.774426] sd 14:0:0:0: [sdb] Write Protect is off [18397.774437] sd 14:0:0:0: [sdb] Mode Sense: 23 00 00 00 [18397.775093] sd 14:0:0:0: [sdb] No Caching mode page present [18397.775103] sd 14:0:0:0: [sdb] Assuming drive cache: write through [18397.778319] sd 14:0:0:0: [sdb] No Caching mode page present [18397.778330] sd 14:0:0:0: [sdb] Assuming drive cache: write through [18397.779229] sdb: sdb1 [18397.781520] sd 14:0:0:0: [sdb] No Caching mode page present [18397.781532] sd 14:0:0:0: [sdb] Assuming drive cache: write through [18397.781542] sd 14:0:0:0: [sdb] Attached SCSI removable disk so far, so bad... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021375 Title: Nautilus says the USB stick is read only when it is not To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1021375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
