You can always unmount in a save way using the console, that said the "safe remove of a device" is under the hood nothing else but un-mounting all mounted partitions of a device.
sudo -s -- 'sync; umount <mounted-folder>'

I found a way to do this in Nautilus, in Ubuntu 12.04, using Gnome desktop (not Unity). There was no "unmount" in the right-click menu. But, there was an icon to the right of the name of the USB hard drive. I clicked it and it did the unmount, and after that 1) "Mount" was in the menu and 2) "Safely remove" worked fine.

Your drive may have suffered from a fault in its flash memory architecture. This sometimes can be resolve by performing a low lever format of the drive.
Usually low-level format utilities may be obtained from the manufacturer, but unfortunately a quick search on Alcor Micro did not reveal any utility downloads. You may nevertheless be able to find such a ...

You can do a Persistent install using Startup disk creator however a Full install has several advantages, it can be upgraded/updated, is more secure, and boots much faster than a Persistent install, also a Persistent install is initially limited to a 4GB persistence) file as it is FAT32. Persistence can be increased by using an ext2 partition named casper-rw ...

Have you tried to change the CMOS options so that the Flash drive is available for booting before everything but the CD drive. You can do this by clicking F2 (on my laptop! Sometimes the Delete or F12 button) as you boot up.
Next, using your keyboard left and right arrows, navigate to Boot and follow the onscreen instructions

First find your USB flash drive's device block - plug in the drive and run dmesg | tail. The device name should be of form sdX.
cryptsetup lukscreate /dev/sdX - this will prompt for a passphrase, create one.
cryptsetup luksOpen crsdX /dev/sdx - this will prompt for the passphrase again.
mkfs.vfat /dev/mapper/crsdX - create the file system
Now you can mount ...

It actually sounds more like an issue with your computer's hardware than an Ubuntu specific issue. Do you have issues with all USB devices, or is it just disk drives?
You could plug something in and use lsusb to check if the device is actually there and unmounted or if it's physically becoming disconnected due to some fault with the USB ports.
You could ...

Open disks from dash, delete the partition that's already on the drive by pressing the - sign, Only if no longer needed.
Create a new EXT4 partition, by clicking the + sign, and format the drive.
Once the partition is created, click on the little wheels to format the drive.

I was having a similar problem. I resolved this by first unmounting the partition via cli:
sudo umount /dev/sdb1 (or whatever your usb is)
Then formatting the partition for ext4 (it cannot be formatted while mounted/in use):
sudo mkfs.ext4 /dev/sdb1
That should do the trick, worked for me.

The Live USB cannot be updated or upgraded. What you have is an image of a DVD inside the USB. You will have to install Ubuntu into another drive to get all the benefits of a full install. The second drive can be another USB drive.See How do I install Ubuntu to a USB key? (without using Startup Disk Creator) for how to do a full install of Ubuntu in an USB ...

This utility will run under Linux.
Multisystem is an awesome tool created by LiveUSB.info, that works
similar to our Windows based MultiBootISOs USB creator, but was
created for use within Linux. It also uses Grub2 instead of Grub
Legacy, and can be run from within Ubuntu Linux to create a Custom
Multiboot UFD containing your favorite Bootable ...

watch out, this may the case why your USB device is not bootable.
Maybe try repartitioning the USB stick?
Did you partition it yourself or left the MBR as it was before install?
In my honest opinion installing livecd on the USB with the startup creator, then burning down the partitions and install

It is normal to get this dialogue when using thunar, as noted here briefly at the Xfce wiki, although it will obviously only be displayed if you have a notification daemon installed. When a filesystem is unmounted any pending data is written and then the device itself can be removed. However, sometimes the filesystem cannot be unmounted if a process is still ...

Try running the unmount command with root permissions from the CLI.
Open a Terminal window with alt+t or by searching for "Terminal" in Finder.
Going off the data you provided about the error, it looks like your HDD is mounted at '/media/My Passport'. To unmount it, run sudo unmount "/media/My Passport". Enter your password when prompted.
If it's not ...

You only mention one storage device type - usb stick. Whenever usb devices don't mount correctly check that you don't have package called usbmount installed. If it is, remove it and life should be back to normal after that (you might need to restart).

Solution 1: Try the Disks program (if you run Ubuntu with a GUI).
(check that the gnome-disk-utility package is installed)
(make sure that udisk2 package is installed)
Hit SUPERA to open the Application Lens and type Disks in the Search Applications field.
(SUPER is probably the key with the Windows icon.)
In Disks you can play with the automount ...

sudo lsusb is the first step. looking in /mnt or /media, or /anywherelse implies the hardware has been mounted. The hardware maybe plugged in but not mounted.
If you see the device listed, then you can look for the /dev/ assignment in dmesg
here is dmesg output of when i just pluged a memory stick in my computer:
[10527.883515] sd 6:0:0:3: [sde] 126912 ...

sudo lsusb will tell you what usb devices Linux detects. Whether a usb storage device mounts, or is detected, are separate issues. sudo lsusb -v will give verbose output, possibly more information than you want if the OS truly doesn't recognize the device.
alternatively, you could compare the lists of devices in /dev before and after plugging in the usb ...

The best software to create a bootable USB from a .iso file for me is multisystem

A "bootable" USB disk requires a "bootable" ISO files to be burned on it.
The litmus test is simple: If burning the said ISO on a DVD would get you a bootable DVD, then any of the methods (like "startup disk creator") to "burn" the ISO on usb would do the trick. But if the ISO would not give you a bootable DVD, then it can NEVER give you a bootable USB, ...

When you install on the external drive, the simplest way to install it would be to make two partitions. First: Make a swap partition. This needs to be >= the amount of physical RAM you have installed to your computer. Second: Make the remaining memory an ext4 linux partition, and set it's mount point to /. Choose the ext4 linux partition and install. Then, ...
