TestDisk can recover deleted files especially if the file was not fragmented and the clusters have not been reused. There are two file recovery mechanisms in the TestDisk package: [2] TestDisk proper uses knowledge of the filesystem structure to perform "undelete". PhotoRec is a "file carver". It does not need any knowledge of the file system ...
Windows File Recovery is a command-line software utility from Microsoft to recover deleted files. [1] [2] It is freely available for Windows 10 version 2004 (May 2020 Update) and later from the Microsoft Store. [3] Windows File Recovery can recover files from a local hard disk drive (HDD), USB flash drive, or memory card such as an SD card.
Although both technologies are similar, 32-bit disk access was introduced with Windows 3.1 and file access with Windows for Workgroups 3.11. 32-bit file access provided a 32-bit code path for Windows to directly access the disk bus by intercepting the MS-DOS Int 21H services while remaining in 386 protected mode and at CPU speeds, rather than ...
It bypassed MS-DOS and directly accessed the disk, either via the BIOS or (preferably) 32-bit disk access (Windows-native protected mode disk drivers). This feature was a backport from the then-unreleased Windows 95, as suggested by Microsoft's advertisements for Windows for Workgroups 3.11 ("the 32-bit file system from our Chicago project").
Thus, Windows 11 is the first consumer version of Windows not to support 32-bit processors (although Windows Server 2008 R2 is the first version of Windows Server to not support them). [148] [149] The minimum RAM and storage requirements were also increased; Windows 11 now requires at least 4 GB of RAM and 64 GB of storage. [150]
On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk). The Windows Server version of CHKDSK is RAID-aware and can fully recover data in bad sectors of a disk in a RAID-1 or RAID-5 array if other disks in the set are intact. [11]
Recuva (/ r ɪ ˈ k ʌ v ə /) [2] is an undeletion program for Windows, developed by Piriform Software. It is able to undelete files that have been marked as deleted ; the operating system marks the areas of the disk in which they were stored as free space. [ 3 ]
In Windows Vista, Windows 7 and Windows 10, System File Checker is integrated with Windows Resource Protection (WRP), which protects registry keys and folders as well as critical system files. Under Windows Vista, sfc.exe can be used to check specific folder paths, including the Windows folder and the boot folder.
