Tested it now with my smarthone as a disk drive and an usb stick too - wasn't able to reproduce it either. Seems like it is the external usb hdd the only thing to behave this way, it is a Western Digital "My Passport" drive, FWIW.
If it is the disk itself behaving incorrectly, then sorry for having wasted your time. I upload the video anyway. [...] I have had a look at dmesg before and after the "safely remove" action: This is how it has been automounted after being plugged: [11589.657577] usb 2-1.1: USB disconnect, address 16 [11595.790837] usb 2-1.1: new high speed USB device using ehci_hcd and address 17 [11596.532849] scsi18 : usb-storage 2-1.1:1.0 [11597.529850] scsi 18:0:0:0: Direct-Access WD My Passport 0730 1015 PQ: 0 ANSI: 6 [11597.530710] scsi 18:0:0:1: Enclosure WD SES Device 1015 PQ: 0 ANSI: 6 [11597.531795] sd 18:0:0:0: Attached scsi generic sg2 type 0 [11597.532129] ses 18:0:0:1: Attached Enclosure device [11597.532403] ses 18:0:0:1: Attached scsi generic sg3 type 13 [11601.976202] sd 18:0:0:0: [sdb] 1953458176 512-byte logical blocks: (1.00 TB/931 GiB) [11601.977162] sd 18:0:0:0: [sdb] Write Protect is off [11601.977168] sd 18:0:0:0: [sdb] Mode Sense: 47 00 10 08 [11601.978908] sd 18:0:0:0: [sdb] No Caching mode page present [11601.978913] sd 18:0:0:0: [sdb] Assuming drive cache: write through [11601.983144] sd 18:0:0:0: [sdb] No Caching mode page present [11601.983151] sd 18:0:0:0: [sdb] Assuming drive cache: write through [11601.992038] sdb: sdb1 sdb2 sdb3 [11601.996446] sd 18:0:0:0: [sdb] No Caching mode page present [11601.996453] sd 18:0:0:0: [sdb] Assuming drive cache: write through [11601.996458] sd 18:0:0:0: [sdb] Attached SCSI disk [11602.868941] EXT4-fs (sdb3): mounted filesystem with ordered data mode.

Opts: (null) as far as I see it gets at the new automount a new usb address? Can it be that the drive after unmount somehow reinitializes itself presenting itself as another device, or is being recognized as a new device and this is why re-automounted? ** Attachment added: "recordmydesktop output, mplayer plays it alright." https://bugs.launchpad.net/ubuntu/+source/unity/+bug/748151/+attachment/1970456/+files/out.ogv -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/748151 Title: "Safely Remove" USB drive works great, but is remounted immediately -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
