Hi:

Here is another way.

IF NOT IsDiskin("a:")
= MESSAGEBOX("Drive 'A:' not available")
ENDIF

FUNCTION IsDiskIn
LPARAMETERS tcDrive
*
* Defines from Winbase.h
*
#DEFINE SEM_FAILCRITICALERRORS 0x0001
#DEFINE SEM_NOGPFFAULTERRORBOX 0x0002
#DEFINE SEM_NOALIGNMENTFAULTEXCEPT 0x0004
#DEFINE SEM_NOOPENFILEERRORBOX 0x8000

*
* SetErrorMode determines whether the system handles serious errors
* or whether the program handles them
*
DECLARE INTEGER SetErrorMode IN win32api INTEGER

*
* Declare local variables
*
LOCAL lnResult,llIsDisIn,lcDrive

*
* Initilize
*
llIsDisIn = .F.
lnResult = 0
lcDrive = tcDrive

*
* Turn off critical errors
*
lnResult = SetErrorMode(SEM_FAILCRITICALERRORS)

*
* Check and see if the disk is in
*
IF DISKSPACE(lcDrive) = -1
llIsDisIn = .F.
ELSE
llIsDisIn = .T.
ENDIF

*
* Reset the thing the way we found them
*
lnResult = SetErrorMode(lnResult)

*
* Return the result
*
RETURN llIsDisIn
ENDFUNC
HTH,
