I have extracted the file to my external hard drive and re-conected to the new computer and after starting transfering the file it goes ok... then after waiting with no advancement in the file transfer the message pops out. I have transfered the inbox messages (about 0.5 GB) and had no problems, I followed the steps of doing a clean boot but still dont manages to transfer the file... help please

Hi, Before moving on, I would like to share the following information with you. When you receive semaphore timeout messages, the messages are usually the result of one of the following: 1.A heavy load on the server is causing processes to be delayed from releasing semaphores. 2.A process has crashed while holding a semaphore, causing other processes to block when trying to acquire the semaphore. 3.Deadly embrace, semaphore contention where two tasks are waiting on each other and neither task is able to break the loop. In the simplest case, thread A is trying to get a semaphore which is owned by B, while B is trying to get a different semaphore which is owned by A. More complex combinations are also possible: A wants a semaphore owned by B, who wants a semaphore owned by C, who wants a semaphore owned by A, etc. 4.If a process was to fail to set a semaphore during execution, another process dependent on the semaphore will be blocked awaiting the semaphore. Then, lets confirm the following points: 1. Are you using Windows Easy Transfer? Or just copy it directly? 2. Can you transfer this Outlook file to another known computer? 3. Can you transfer this Outlook file in Safe Mode? 4. Are you using USB cable on external hard drive? Or FireWire cable? If hardware support, could you please try to use another cable to troubleshoot this issue? For your convenience: Run Windows Vista Safe Mode ================================ 1 Detach all unnecessary peripheral devices from your computer, such as printers, scanners and removable storage devices. 2 Restart the computer. 3 Keep pressing the F8 key until the Windows Startup menu appears. 4 Choose Safe Mode, and press Enter. Hope it helps.
