On the other hand, whenever a file with a clear archive bit is modified (edited), or copied or moved to a new location, the operating system will set the archive bit on the target file. Typically on a file system that has never been formally backed up, nearly all of the files will have their archive bits set, as there are few applications that ...
The Free Edition (limited to Windows 32-bit Win2000 / XP / 2003) is able to use 'invisible' RAM in the 3.25 to 4 GB 'gap' (if your motherboard has i946 or above chipset) & is also capable of 'saving to hard disk on power down' (so, in theory, allows you to use the RAM disk for Windows XP swap file and survive over a 'Hibernate').
The user may later request an earlier version to be recovered. This also allows data backup programs to archive files currently in use by the file system. Windows Vista also introduced persistent shadow copies for use with System Restore and Previous Versions features. Persistent shadow copies, however, are deleted when an older operating ...
The boot code in the VBR can assume that the BIOS has set up its data structures and interrupts and initialized the hardware. The code should not assume more than 32 KB of memory to be present for fail-safe operation; [1] if it needs more memory it should query INT 12h for it, since other pre-boot code (such as f.e. BIOS extension overlays, encryption systems, or remote bootstrap loaders) may ...
Formatting a disk for use by an operating system and its applications typically involves three different processes. [e]Low-level formatting (i.e., closest to the hardware) marks the surfaces of the disks with markers indicating the start of a recording block (typically today called sector markers) and other information like block CRC to be used later, in normal operations, by the disk ...
Optionally (by adding the /S, for "system" switch), format can also install a Volume Boot Record. With this option, Format writes bootstrap code to the first sector of the volume (and possibly elsewhere as well). Format always writes a BIOS Parameter Block to the first sector, with or without the /S option.
The TRIM command enables an operating system to notify the SSD of pages which no longer contain valid data. For a file deletion operation, the operating system will mark the file's sectors as free for new data, then send a TRIM command to the SSD. After trimming, the SSD will not preserve any contents of the block when writing new data to a ...
Additionally, the file can be edited within Windows using a text editor if the folder view option "Show hidden files and folders" is selected, the folder view option "Hide protected operating system files" is unchecked, and the "Read-only" option is unchecked under the file's properties.
