Norton Abrasives 8 manual Disk Access Errors

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.
