Checking a disk
The third-party utility EFICHK.EFI is useful for checking some basic statistics of a
disk. The output will be similar to Figure 4-6.

Deleting the disk content
There are situations when it is necessary to delete the contents of the disk. For
example, you want to install an operating system on a disk that was previously
used in a non-EFI system (that is, with a disk with a standard Master Boot
Record (MBR) or you want to delete a partition that is reserved and cannot be
deleted by other means (for example, a Microsoft Reserved Partition—see
“Microsoft Reserved Partition” on page 137).
Tip: If you need to perform a low-level format of the disk, use the LSI
Configuration utility, which is described in “EFI tips and tricks” on page 102.
