Hi! I'm using Acronis True Image Workstation 9.1 to create images of some old disks in equipments running old Unix systems in order to backup those disks and, when needed, replace them with other disks with the same image. I'm using Acronis because it seems the best product available to do this kind of things. The problem with these backups is that the disks are small (6 Gb, 10 Gb), so, when I'll need to substitute one of these disks with a new one, it will be bigger (the smallest availabe in market nowadays). I had success migrating 10 GB disks to 20 Gb disks of the same label and a 40 Gb disk of other label. I did many tests with different kind of disks and no problem was found. I made images of the 10 Gb disk and then pass them to bigger disks, put them on the system and everything run as it should. My problem is to make the same thing with 6 GB disks Fujitsu MHK2060AT. I make the image, pass to a 10, 20 or 40 GB disks of other labels (Toshiba and Seagate) and when I put the new disk on the system, it doesn't run properly. The system starts briefly but then I have error messages from the Unix system and it reboots. OM panic: srmount - not a valid root erro 0 OM: incident send incident_om_panic error -7 SM: pppSmInit() DM ppp task unreachable: error=-7 SM warning: cannot attach ppp interfaces. It's strange because the disks should have the same information, sector by sector, but there's something that's not the same because the system fails to read something (this never happened with the disk of 10 Gb). I compared the sectors in the two disks with Acronis PartitionExpert (the original and the one that got the image) and they were exacly the same. Disk 1: -> partition1 - 0x63 (Unix) Total size: 5.593 Gb First physical Sector: 1 (cyl. 0, head 0, sec. 2) Last Physical Sector: 11,728,395 (cyl 730, head 14, sec. 63) Total physical sectors: 11,728,394 Block Size: 512 bytes -> partition2 - 0x62 (Unknown(62)) Total size: 2.307 Mb First physical Sector: 11,728,395 (cyl. 730, head 15, sec. 12) Last Physical Sector: 11,733,120 (cyl 730, head 89, sec. 63) Total physical sectors: 4,725 Block Size: 512 bytes The second disk (the one who got the image) has exactly the same structure. The only difference is that has unallocated space in the end, because it's bigger. I also compared the two disks with Acronis Disk Editor and the paratition table was the same. When I saw the fisrt sectors in hexadecimal, everything was equal, too. But something must be wrong somewhere in the disk. Any help? Does anybody have any idea? It would be very appreciated. Thanks for your attention.
