Appendix B: Troubleshooting118
access. To solve the problem, modify your CONFIG.SYS file by commenting the
EMM386 line. For more information about memory requirements, see
“PartitionMagic System Requirements” on page 4.
The DOS PartitionMagic executable requires a minimum of 585 KB of memory
in the first 640 KB of the computer’s address space (conventional memory) and 8
MB of total memory. For possible solutions if you have insufficient conventional
memory, see “Freeing Memory to Run PartitionMagic under DOS” on page 110.
You may be able to resolve this problem by rebooting to an A: prompt, typing
LOCK_C:, and running PartitionMagic from the rescue disks.
#8 Could not allocate/deallocate DOS real mode memory
The DOS PartitionMagic executable running under DOS, Windows 3.x,
Windows 95, and Windows 98 requires some memory in the first 1 MB of the
computer’s address space (PartitionMagic uses a DOS extender). If not enough
memory is available, PartitionMagic cannot access the hard disk. For possible
solutions, see “Freeing Memory to Run PartitionMagic under DOS” on page 110.
#27 Cannot lock drive
Under multitasking operating systems such as Windows 95, PartitionMagic must
lock a partition before it can safely modify it. If the hard disk contains files that
are in use by another process, PartitionMagic cannot lock the partition.
#29 Cannot lock a locked drive
Verify that the partitions you are attempting to modify are not on a locked hard
disk.
#34 The Beta version is no longer safe to use
Norton occasionally releases beta versions and evaluation versions of
PartitionMagic. Both versions are not as safe as release versions; therefore,
Norton builds an expiration date into each version. After a predetermined test
period, the beta or evaluation version no longer functions.
Disk Access Errors (40–56)
Errors in the 40–56 number range indicate that accessing your disk is not possible, and
often result from hardware problems. Some problems may have simple solutions; for
others, the only solution may be replacing the hard disk. When possible, PartitionMagic
detects major errors before any changes have been made so you can back up your data
before replacing the hard disk.
