We don't care about what u say ,Primus84 asks what size USB drive needed for Lion so?
No it came with no media. I guess the rationale is if I have to do a restore it'll have to be done via the Internet. In my case I just want a copy of the install so I can do it from a USB key if I ever have to restore.
Just saw this app today called Lion DeskMaker that automates the process and says it will work with a 4GB USB key. Have not tried the app myself.
So I'm going to try a different method to get my hands on the .dmg file. Hooked up an external USB drive enclosure to the Mini. Rebooted the Mini and held down the Command and R keys. Told recovery to install Lion on the USB enclosure. Once download completes I'll let it auto reboot and old down the Option key to bootnback into OSX on the Mini hard drive. From there I should be able to find the .dmg Lion install file on the USB enclosure. We'll see.
I just tried this app with a 4GB usb key and it failed. Gave some Finder error: connection couldn't be found, or something like that, if I recall correctly.
