Small wonder you're having problems with this. I can't even understand why it compiles, maybe it's a bug, but I can't image that using "done" inside if-statements to close the surrounding loop is legal.

With loops, use either "break" to break out of the loop, or "continue" to start the next iteration.

Aside from that, if the drives in $alldrives are space seperated, you can rewrite your loop to
Code:
for i in $alldrives
do
    ....

Future debugging tips:
  • set -x shows a nice trace on stderr of what is done
  • the -n switch to ksh/bash does a syntax check without running the script

Just verfied on Linux using your snipped of code:
Code:
$ bash -n test.sh
test.sh: line 20: syntax error near unexpected token `done'
test.sh: line 20: `done'
$ ksh -n test.sh
test.sh: syntax error at line 20: `done' unexpected

Replacing your "done"s with "continue"s:
Code:
$ ksh -n test.sh
$ bash -n test.sh

EXECUTE(7)                                                         SQL Commands                                                         EXECUTE(7)

NAME

       EXECUTE - execute a prepared statement

SYNOPSIS

       EXECUTE name [ ( parameter [, ...] ) ]

DESCRIPTION

       EXECUTE  is  used  to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the pre-
       pared statement must have been created by a PREPARE statement executed earlier in the current session.

       If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE
       statement,  or  else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of
       their parameters; the name of a prepared statement must be unique within a database session.

       For more information on the creation and usage of prepared statements, see PREPARE [prepare(7)].

PARAMETERS

       name   The name of the prepared statement to execute.

       parameter
              The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible  with  the
              data type of this parameter, as was determined when the prepared statement was created.

OUTPUTS

       The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE.

EXAMPLES

       Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation.

COMPATIBILITY

       The  SQL  standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a
       somewhat different syntax.
