I have copied entire hard disk with Windows XP on it to the new hard disk. I used the Partition Wizard CD from Paragon to do it. I disconnected the old hard disk from the system and booted computer. It went well and I am using it now. My computer is in stand by 24 h and on the morning I have found the Windows error message: "Wrong (or incorrect) partition ID". Nothing more! When I clicked it away (the only thing I could do) I get another Windows error message: Can't open/write file. Nothing more! When I booted computer from partition wizard CD the Windows XP partition was unallocated! I tried to recover partition and the wizard found the old partition and data but when I choose to make recovery it shows me again that the partition is unallocated! I am a little afraid and will know what is the correct partition ID and how to change the partition ID? And why the Partition Wizard says that partition is unallocated when Windows XP says it is and computer boot from it and I use it now? And why the Partition Wizard says that it can recover the partition and doesn't do it when I order it. Please help me but instruct me as a newbie I am.
