DSKANA DSK1:/C 

ENTER

As mentioned above, you need to use the /L or /E option to find the location of any file errors DSKANA
detects. The /C option is discussed in the next section.

To see the list of DSKANA options, type 

DSKANA 

ENTER

 without a device name.

The CHECK Option and Automatic Backups

At times, you may want to have DSKANA examine a disk without rewriting the bitmap, especially when
using a scheduled backup method which runs DSKANA automatically before your backup.

The reason for this is simple: if anyone on your computer leaves a file open on the device DSKANA is
checking, DSKANA doesn't know the file is open. So, it doesn’t take the open file into account when it
rewrites the bitmap. When the person returns in the morning and writes the file to the disk, it causes a
bitmap error. This could corrupt the disk, causing you to lose data.

To run DSKANA without rewriting the bitmap, use the /C option. You see DSKANA's normal display
when you use /C, except for the [

Rewriting BITMAP

] message.
