Hi , Has anybody experience with making a hard drive Image ? I have an old SCSI drive with very old NT and OS/2 installed on it and I want just to have a backup of this drive so that I can recover it any time. I wanna track by track backup i.e. exact image of hard drive with OS/2's boot manager and everything else. I've connected another (BIG) IDE drive to the computer, installed FreeBSD and executed dd like below "dd if=/dev/da0 of=/backups/scsi.img" At the end of execution dd has reported exactly the correct number of blocks copied. Each block is 512 bytes by default. 2109840 blocks in and the same amount out. Fdisk reports 2109839 for number of sectors on that SCSI drive and it is ok cause the numbering of sectors begins from 0 (I think on SCSI drive one sector is 512bytes). The question is whether I'll get the same bootable SCSI drive (with that old NT and OS/2 ) when I later execute dd if=/backups/scsi.img of=/dev/da0 ? Please I need your opinion cause I am in doubth.
