to ChristineBCW, great input and much appreciated,
You shouldn’t have any worries about PLUS R vs. MINUS R DVDs. PLUS R’s allow for a multi-session disk (backing up files today, then setting the disk aside, coming back in a few days and backing up more files) and there’s some argument that this being a newer ‘standard’, disks are made to a higher quality.
yes, from past info couldnt find real difference between minus-R or plus-R; but if sony recommends the minus-R dvd, and didnt know about the plus-R’s as multi-session discs, and maybe ths why sony prefers the minus-R’s so as the the dvd being dedicated.
USB sticks can be prone to electrostatic issues - death - so I recommend using the formal “Safely Remove USB” options in the lower right corner of your Win screen each time. This terminates electrical current to that USB port, saving both your computer’s USB port AND the memory-stick itself. (Those sticks can be replaced at least - burn out the USB connector in the computer, though… ugh…)
had learned ths some years back from my own mistake and fried a usb drive, didnt know about the risk burning out the usb connector/port, ouch, and so good to understand the cause now, thx.
Is anyone else aware of a USB 3.0 limitation on bootability? I’ve not read this or even considered it - I’d think “the device is either bootable BY the computer’s BIOS setup, or it’s not” and the data-transfer rate (which is primarily the USB 2 vs. 3 distinction) isn’t an issue. But who knows
yes couldnt make sense of ths, though ths is first time having laptop w/ SSD drive built in, and doubt SSD has relevance but dont know; and had to post b/c was odd, i mean if you have usb 3.0 port you use the usb 3.0 connector/flashdrive, but not for recovery, um, what.
using the dvd-R media for recovery appears the safe bet;
though the point made was that laptop users not having built-in optical drives and dont use them now, and the usb flashdrive was the obvious choice for recovery(and optical drives are phasing out); i wouldnt know which, or if just a preference;
and video noted 6.8 gb was the mentioned file size for win7/ or 8 bootable recovery usb drive so he used 8gb, sounds big to me, or error, but i plan to check the file size as burn the recovery dvd(s), o the fun.
again thx very much for assistance,
