RAWDISK.SYS v1.1 is available by anonymous ftp from: ftp.uni-duisburg.de: /pub/pc/misc/rawdsk11.zip login: anonymous, password: e-mail address Version 1.1 of RAWDISK.SYS (raw disk device driver for DOS) fixes the following two bugs: 1. DR-DOS's CHKDSK complains about an illegal drive for RAWDISK.DRV. 2. Successful restore of a backup was prevented by version 1.0 under certain circumstances: if the program you use for restore (ie that writes to the disk via RAWDISK.SYS) wrote an updated directory entry first before reading the FAT to get the available bytes on the drive, RAWDISK.SYS returned a virtual FAT indicating a full drive. This prevented successful restore. Both bugs are fixed. BTW, RAWDISK.SYS is a DOS device driver, that maps an arbitrary portion of a harddisk (given by a start- and endcylinder) onto a logical DOS drive. The HD area is accessed (read or written) through a regular DOS file. Logical drive administration areas (bootsector, FAT and rootdirectory) are totally virtual, hence no additional HD space is required. sorry for the inconvenience, Juergen -- Juergen Prang | prang@du9ds4.fb9dv.uni-duisburg.de University of Duisburg |******************************************** Electrical Engineering | Logic is a systematic method of coming Dept. of Dataprocessing | to the wrong conclusion with confidence
