2011 on Windows 7 appears to hang on calculating remaining time
Running Windows 7 Enterprise on HP 8540p laptop. 300GB HD w/37GB used. Backing up to an IEEE 1394 external drive. Similar backups on an XP machine with Acronis 8 ran about 45 minutes. Now, the machine sit for about 30 minutes apparently calculating backup time. Can anyone suggest why this may be happening? Thanks

Pat,
Thanks for your reply. I found some forum and KB articles which led me to alter the disk policy to optimize for performance. The backup is now running at about the same speed as on XP. Odd, since I think the default settings are the same. Maye that's just IEEE and W7, as you say. I haven't tried USB yet.
Here is a snip of the procedure I used from another thread:
I spent a week trying to solve why my partition backup to an external hard drive was extremely slow (estimated 9 days for approx 475 GB on the drive) and I finally found the answer.
(fyi the answer was NOT applying the lastest snapapi drivers)
I found this by googling and it reduced the time from 9 days to 8 hours and the backup completed successfully. Hope this helps. --------------------------------------------------------------------------------------------------------------------------------
The default Windows settings for FireWire-connected drives can reduce your External drive performance by as much as 90%. This problem is easily corrected, just follow these instructions:
1. Open "My Computer" or "Computer" from your (Start) Menu or Button.
2. Right-click the external Hard disk drive from the list and select "properties"
3. Click the "Hardware" tab.
4. Highlight the drive your having problems with from the drive list and click on "Properties".
5. Click on the “Policies” tab.
6. You will see two radio buttons - "Optimize for quick removal" and "optimize for performance".
7. If not selected, select "Optimize for performance" and click on "OK". If running Vista or Windows 7 also check "enable write caching on the disk".
8. Click on "OK" and exit.
Lighting speeds should now be reached.
This problem can affect XP, Vista or Windows 7. It may improve performance for any drive connected via FireWire.

Good catch. You should experiment with regular USB 2.0. I couldn't get my 1394b disk to run at the full speed and typically got a transfer rate about 13-15MB/s whereas I can see low twenties with USB
