This page gives low-level information about your current drive, and all
real drives in your system.
INFOPLUS will read the boot sector of the current drive. This gives
information about that drive:
Media: The type of drive (RAMdisks may show up as anything.)
Sectors/cluster: The number of sectors that make up a cluster, the unit
that DOS allocates disk space in.
Bytes/sector: How big those sectors are.
Reserved sectors: How many sectors are set aside for special use.
FATs: File Allocation Tables. DOS uses these tables to keep track of which
clusters are currently in use, free, or bad. Most disks have 2.
Sectors/FAT: How many sectors are needed to hold all the FAT information
for each copy of the FAT.
Root directory entries: How many files can be put in the root directory of
the disk. Hard drives usually have 512.
Heads: How many read/write heads are on the disk.
Total sectors: The number of sectors on the drive.
Sectors/track: How many sectors are are on a track. In other words, the
number of pie wedges.
OEM name: A string that is usually in the boot record. Tells which version
of DOS formatted the disk.
Extended boot record: DOS 4 and newer supports an extended record that
contains the volume lable, the serial number, and a
FAT type string.
For each physical drive in the system, you can <DnArw> to get information
on all the drives. Most of the information is the same as the above, with
some extra information:
DPB valid: This lets you know if this information is any good.
Device header: The address of the driver for this disk.
Root directory sector: The sector where the root directory begins.
