Hard Disk Drive
Note: Primary storage is accomplished by an integrated flash circuit. BIOS software in the
MX1 provides an interface layer between the operating system and the hardware. To the
operating system (DOS) and the application software, the flash looks like a small hard
disk drive. The flash drive is still susceptible to many of the same problems as a hard
drive. If the computer is interrupted while writing data to a disk, the disk may become
corrupted. Interruptions include such things as power failure, operator generated power
removal, operator generated reboot or catastrophic software failure (crash).
If you have problems with the hard disk drive, run the DOS CHKDSK utility. CHKDSK analyzes
the directories, files and File Allocation Table (FAT) on the flash disk.
For information on running CHKDSK, refer to the DOS documentation.
If CHKDSK does not report any errors and the hard disk still has problems, contact LXE
Technical Support.
