I'am using Alphastation 255 for process control . It comes with a 4.3 GB harddisk which is now making terrible noise after many years of operation . I tried backup/image dka100: dka200: to a 18 GB target disk . After completion i tried booting copy by Boot dka200 .
The system goes on a infinite very slow read cycle after normal startup echoes " loading network base image .... ".
Now i tried :

1- An old 4.3 GB harddisk and 8.5 GB harddisk using same command . The copies are good and working . I further tried 40 GB and 73 Harddisks but they have same problem as 18 gb one .

2- I attached not working harddisk copies to my emulator on Win2K3 server and copied it to an image file on local disk . Booting on emulator was no problem. I only get stuck with licenses issues . Rest is working fine .I even tried to restore
one blank 4.3 GB harddisk from emulator image . This copy works fine on Alphastation so copy process on 18/40/73
gb Harddisk is fine . Just they are not booting completely on alphastation.
CAN SOMEBODY IN THE WORLD TELL ME HOW TO USE > 8.58 gb HARDDISKS ON ALPHASTATION 255 AS OLDER MODELS ARE NO MORE AVAILABLE . OLDER HARDDISKS ONLY COMES FROM SCRAP YARD AND THEY DONT WORK FOR LONGER PERIODS ???
