 + 
 +<code> 
 +# Change from this 
 +1?DEVICE=C:\FDOS\BIN\JEMMEX.EXE NOEMS X=TEST I=TEST NOVME NOINVLPG 
 +# to this

 +==== Dealing with unable to read hard disk error ==== 
 + 
 +When you use ''fdisk'' to partition the drive, it will initially ask you if you want to use large disks and format with FAT32. If you choose YES, you might end up getting errors when it tries to read the disk later. To solve this, choose NO when it asks you if you want to use extended disks. This will only use FAT16, whicht will limit you to 2GB max disk sizes. However, you can create one primary DOS partition of 2GB and then create an extended partition with numerous 2GB logical partitions. This way you can have an ''E:\'', ''F:\'', ''G:\'', ''H:\\'', etc, each of 2GB.
