chkdsk and disk dismount
i was attempting to run a chkdsk on a 199GB drive and it is giving me a message which states:
Drive has to be dismounted before running chkdsk.
Is it safe to run a chkdsk? or can i easily bring the disk back online after the chkdsk is done?

It is better to backup your important data first. There is a risk of data loss when the chkdsk fix your harddisk.

Especially in the topic:
/x : Use with NTFS only. Forces the volume to dismount first, if necessary. All open handles to the drive are invalidated. /x also includes the functionality of /f.
Chkdsk corrects disk errors only if you specify the /f command-line option. Chkdsk must be able to lock the drive to correct errors. Because repairs usually change a disk's file allocation table and sometimes cause a loss of data.

it was the right one.
It should say something like "ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID". Would you like to force a dismount on this volume? <Y/N> so select Y
If programs or drivers maintain an open handle (EG: you have a file open on the drive) to the disk, chkdsk will not run until it has exclusive access to the drive.
