A while back I bought a pack of 3 SanDisk Cruzer Facet[1] 8GB pen drives
at a bargain price of £9.99 from PC World. I thought they'd come in handy
as usb bootable drives for stuff such as this. Unfortunately, it turns
out I was completely wrong. :-(
They're absolutely fine for storing data but, as far as unetbootin is
concerned, they fail to show up in its usb mass storage drive list (win2k
OS at the time - it's the same story regardless of host OS as it happens).
However, I did notice one oddity about them in win2k's explorer view
(the "My Computer" window). They appear just like an external hard drive,
complete with the same characteristics, rather than as typical flash
media. You'd think making a "HDD-look-a-like" 'bootable' would be a doddle
but the usual flash media tools designed to make usb flash media drives
bootable just can't handle this implementation of flash media based
storage drive.
I daresay there should be a way to make such media bootable by using
more conventional tools designed for disk drives (HDDs and FDDs) rather
than flash media but I've never gotten round to figuring how to implement
this using the iso boot images most flash media tools can utilise with
ease to create bootable flash media from.
[1] I also happen to own an 8GB Cruzer Blade pen drive which behaves just
like all the other 'normal' flash based pen drives I've ever owned from
64MB[2] and up (IOW, no problems using it with Unetbootin).
[2] The same 64MB SD card I once used to boot FreeNAS-generic-pc-0.64
through to FreeNAS-amd64-embedded-0.7.2.4919 from (Mar 2006 to Apr 2010).
After that I was forced to squander a 512MB SD card on this duty, then it
became 1GB and then 2GB. I think the current card (NAS4Free - the renamed
version of the original, still ongoing FreeNAS project) is an 8GB one. I
think I skipped the 4GB stage when the in place image upgrade process
claimed the 2GB SD card I was using had insufficient capacity.
I was forced to go through a rather messy clean install to another
bootable usb drive from which to *install* N4F onto the final working
boot media I'd be using to allow subsequent image updates to be applied
without any such let or hindrance as I had suffered with the 2GB SD card
(which, btw, was well less than half filled at the time). I didn't want
to reach the stage of "Insufficient space to perform the image upgrade"
any time soon, hence the jump from 2GB straight to 8GB.
Aside from the possible issue of those Kingston DataTraveller 16GB G4
thumb drives being differently implemented from the more usual mass
storage format expected by Unetbootin (or whatever built in "create a
bootable flash media drive from an ISO image" utilty you're currently
struggling with), I'd say 16GB is a wiser choice than my own 8GB one.
