I have written code for decades, and I never ever read data off of a device, unless it was a serial communication, bit by bit…
I see advertising for various products saying bit-level copy, bit-stream copy, specially for data storage devices - not data communication.
How do they copy bit level?
And, what benefit is to a forensic investigator that each bit is individually copied, instead of copying a whole block and verifying a whole block?
Or, am I just too picky about the use of "bit-level"?
😯 Or am I just too old?
For disks, sectors are like bits. These are the lowest level of data.
With SIM Cards we can use bit nibbler (but they are invasive) to search for every bit in files whether logical or not.
A GSM SIM can take about 9-hours and a 3G USIM can take 26-hours, dependent on memory size.
When I read "bit" from a technical vendor, for a technical product I think of a bit as a single off/on 0/1 item; not as "one bit of the stuff" as in one part of…
Even streaming internal data is by bus width, which is never a single bit.
Are bit nibblers actually read individual bits?
I believe what they are trying to get at is this…. If all the bytes match up, all the bits match up… If the smallest amount you can read is a sector, then you have 512 matching bytes (all being well) and 4096 matching bits…
It is not possible to read individual bits from modern HDD's, more data is read and processed in order to provide you with your individual bit…
