Does the system use the space on the hard disk which has never been written on, before over-writing the deleted files?

Suppose the total capacity of the hard disk is 1 TB but the user always uses about 500 GB. While allocating new space, does the system give preference to the never used space or overwrites deleted files on the disk?
If it is the first case, can deleted files still remain on the hard disk for years?

    That depends on the type of filesystem in use.

  • Deleted files can indeed remain on the hard disk for years, as to how the file system allocates space for new files I' not sure, but it's possible that it also depends on the type of storage. With a spinning HDD it will probably be advantageous to just use the free space nearest to the current position of the read/write head, irrespective of whether it's a never used block or if it belonged to a deleted file.

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...
