It seems that you consider me as a young dumb newbie, which is totally wrong ... I've been playing with PCs since my first 386SX25 in July 1992 and its DOS/WIN 3.0 combo ...Between bulk and retail there really isn't any difference when it comes to the drive itself. The only difference:
Bulk: drive only
Retail: drive+ that cyberlink media suite disc.
That's it. Mechanically they're identical.
I know perfectly what is the difference between RETAIL and BULK, because of my computer experience but also because I've been working in a reseller shop for several years ... !!!
So, can you please stop considering me like a young dumb newbie ??? Thanks in advance !!
