Windows XP hibernating taking too long

My Windows XP machine suddenly started taking very long time to hibernate. It was working fine and I was puzzled with the situation. I had not installed and apps and suspected virus infection.

But then I remembered disabling "Enable write caching on the disk' for my hard-disk few days ago. I enabled the option. Bingo. Problem solved.

Steps:

1. Right click on My Computer -> select 'Properties'
2. Select the 'Hardware' tab from the Pop-up window.
3. Select 'Device Manager' and from the 'Disk drives', right click your hard-disk -> select 'Properties'.
4. In the 'Policies' tab, check the 'Enable write caching on the disk' and click OK.
