how to do a fsck on a linux filesystem

You need to have utils-linux installed to do fsck.

Unmount your device, then do :
fsck -y /dev/sdb1

Note : depending on your device, it may be anything from sdb1 to sdbx. The flag -y is added to have your filesystem corrected automatically.
Do another pass to have a confirmation that your filesystem is cleaned.

To check your hard drive, you need to use a portable OS, such as Puppy or Dog, because it must be unmounted to do a fsck.

Thanks for the info!

In every version of Puppy I have used.
fsck is built in.

Simply do this:

File system check at terminal
Drive has to be unmounted.
Drive id to reflect what drive to check

Code: Select all

e2fsck /dev/sda1

To see options enter e2fsck in terminal.

root# e2fsck
Usage: e2fsck [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
[-I inode_buffer_blocks] [-P process_inode_size]
[-l|-L bad_blocks_file] [-C fd] [-j external_journal]
[-E extended-options] device

Emergency help:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume "yes" to all questions
-c Check for bad blocks and add them to the badblock list
-f Force checking even if filesystem is marked clean
-v Be verbose
-b superblock Use alternative superblock
-B blocksize Force blocksize when looking for superblock
-j external_journal Set location of the external journal
-l bad_blocks_file Add to badblocks list
-L bad_blocks_file Set badblocks list

The flag -y is added to have your filesystem corrected automatically.

NEVER let anything happen automatically to your system without making a backup first!
