random system (FreeCOM) crash

issue reported in devel mailing list https://sourceforge.net/p/freedos/mailman/message/37404053/

A random system (FreeCOM) crash that I cannot reproduce (after editing "FDAUTO.BAT" and installing more packages), but it happened constantly from a fresh installation:

REM "Full installation including apps and games"

REM Boot system from harddisk and ensure there is no disc in CD-ROM (D:) drive

C:\>d:
D:\>cd \
 Error reading from drive D: data area: drive not ready
 (A)bort, (R)etry, (F)ail?  [here, press any key]
 CHDIR failed for '\'.

D:\>c:
C:\>dir /w
