I solved my problem, which was the same as Silambarasan's: A few days ago, out of the blue, it started happening that every time I booted up Ubuntu I got "Your disk drives are being checked for errors, this may take some time"--which it did, at least 10 minutes. Very annoying. Finally I noticed that every time I did a shutdown, just before the machine turned off, the following messages repeated briefly across the screen: "could not write" "broken pipe".
So that was why it was checking at every bootup: it was having a problem at every shutdown. I googled broken pipe, and someone advised fixing it by doing "sudo apt-get -f install", which would tell me of an error in /var/lib/dpkg/status. I did that command, but it didn't mention any error. It said:
0 upgraded, 0 newly installed, 0 to remove and 569 not upgraded.
I hadn't allowed any updates since installing Ubuntu. All was working fine, so why upset the apple cart? But now it seemed like that might be the problem, so I did the updates. I'm on Ubuntu 10.04, so did as follows:
- System > Administration > Update Manager
- Click the Check button to make sure the package info is as up-to-date as possible.
- Click the Install Updates button.
And voila! I no longer get "Your disk drives are being checked..." when I bring up Ubuntu. Susan Anderson 12-8-12
