The Check Disk and Format Disk component is a Delphi wrapper around the Windows APIs exported by fmifs.dll, which are used to format fixed or removable disk drives and perform disk checks on Windows NT4 and later. It supports any local disk drive that has been assigned a drive letter by Windows, just like the normal format and check disk tools in Windows.The component may be used to format disks which are not currently in-use, and to verify the file system on any drives, but only fix it on drives that are not in-use. It may be useful for preparing removable backup drives.These fmifs.dll APIs are undocumented by Microsoft, but were reverse engineering by System Internals. The component is is based on the command line Chkdskx and Formatx applications by Mark Russinovich available from his site.Please note that the fmifs.dll APIs are different from most other Windows APIs and are intended to be interactive with the user, rather than passively accepting input and providing simple output. Specifically, they return progress information that is nornmally seen in a Windows dialog or in a command line window, showing the steps being taken and reporting any errors or corruption found. This component attempts to parse the messages and provide simple return information. A demo program illustrates the use of all the functions. |
