Hi, I probably wasn't quite clear with that question.
I intended to confirm that, as I understand it, getting the boot image downloaded to a USB thumb-drive per your linked site should, like I suppose would be the case always in such an operation, mean that the USB is formatted in the procedure and, though not "ruined", still, by the process, anything on the thumb-drive at the time the download is executed is going to have been erased in a prior format procedure just before the download is executed.
This is a key factor since, lately, I'm finding many of my archived text documents (created using Apache Open Office 4) to be corrupted to the point of being no longer accessible in any legible form--as some here might know it, the dreaded full pages of "####".
I can devote an entire thumb-drive exclusively to the purpose of booting a Linux distribution. It's just that, in creating one, I don't want to inadvertently lose still more documents in a archive set which is rapidly diminishing by attrition of something seriously out of order with Apache Open Office.
thanks, once again. I hope this clarifies my query because, probably tomorrow--too little time left today to launch such a download--I'll proceed to it and, with some luck, get the bootable image onto a thumb-drive which opens the distribution.
cheers, Russ
