1. What does it do below and is it normal - is it IPfire code that
asks computer to read from CD-ROM drive - even though Ipfire is booting
from a USB drive?
1.1 To me it looks like its trying to read or write something
from some blocks from CD-Rom drive. But why does it try to do so?
1.2 And, where exactly does the command come from that asks
that it should read/write from those specific blocks?
1.3 Does that command come from BIOS specifically that it shoudl read/write
those specific blocks?
1.4 What data or file names do these blocks below contain?

1.5 If this is some media error (bad block) - why does it happen on
more than 6 different new USB flash drives? And why that place/area all the time?

"sr 1:0:0:0: [sr0] unaligned transfer"
2.1 From where to where is this transfer happening from?
2.2 Is the transfer happening from the computer and out to/thru network or internet?
3. What does this command do?

4. How many bytes or kb is 1 "logical block"?
(when i check with gparted it reports in "sectors" and not "blocks")
5. What is the purpose of this 2-line command below? Is it normal that this
is done? If so, why?
