 Although every effort has been made to ensure that HDCPM works properly, there is a chance of hard disk data corruption in case of a stray bug in the code. So make a backup of your hard disk before installing and trying out the ROM. I'll not be held responsible for any data loss or damage to your hard disk.<br />

-HDCPM is not FAT aware. It utilizes code to search in the root directory of a FAT formatted medium in order to find the CP/M image files. Then it finds the LBA of the first sector of each file and passes it to the CP/M hard disk driver. The CP/M hard disk driver doesn't know anything about FAT or image files. It accesses the image file as if it was a real hard disk. It works on the sector level with LBA addressing so it expects the 'hard disk' to be a continuous block of sectors.<br />

 A CP/M image file can easily become fragmented during its creation, especially if the hard disk is nearly full. I advice you to create/copy your CP/M image files to your FAT formatted hard disk/partition while it is still empty. [https://www.cpcwiki.eu/index.php/Albireo Albireo] incorporates a file management IC that performs FAT file system operations and handles fragmented files properly. In such case fragmented image files is not a problem. HDCPM will never fragment a CP/M image file.<br />

 You can also create one or more partitions in order to format them to [http://www.seasip.info/Cpm/format31.html CP/M-80] and use them exclusively for CP/M. In such case you must make sure that the size of the partition is big enough to accommodate your file system.<br />

 HDCPM can't be used to partition your hard disk. In order to create partitions you must connect the hard disk to a modern computer and use its partitioning utility.<br />
 Use the command |HDDEF to find the exact length of the file system/partition. When you have created the partition use the HDMGR.COM utility in order to format it.<br />
