A pretty expensive (Samsung) USB-drive I have causes weird errors. The problem might be a computer I have connected it to (this computer's SSD broke down in a similar way) but to rule out that it is this USB stick that is broken I would like to perform a hardware test on it. How can I do that on a Mac?

    Sorry, I should have mentioned that. Yes I have "Erased" it using DU but as far as I know that doesn't include a "quality check", it just writes a new partition table.

Open the Terminal.app in Applications/Utilities.



Cut and paste this inside to install Brew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"



Install e2fsprogs with brew:
brew install e2fsprogs



Type diskutil list to find your device (/dev/diskX)



Run badblocks on your device: (replace the X with your device number)



/usr/local/Cellar/e2fsprogs/1.44.3/sbin/badblocks -v /dev/diskX

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
