controller has been changed, (5) the BIOS has been upgraded, (6) the BIOS LBA
setting has been changed, or (7) there is a partition table virus present on the hard
disk.
In most instances, you should resolve the problem as explained in “Resolving
Partition Table Errors” on page 114. You can also use a virus scanning program
to remove any partition table virus. Data loss is possible if the number of heads or
sectors per track has changed since you first created your partitions.
#117 Partition’s drive letter cannot be identified
Under OS/2, PartitionMagic must be able to find the drive letter for each partition
before modifications can be made. There are various reasons why OS/2 might not
be able to find a drive letter for each partition. For example, a driver on your
system may change the drive letters from their defaults, or your partitions may
not have serial numbers.
You may also see this error when running PartitionMagic under Windows.
The solution is to run PartitionMagic from DOS or from MS-DOS mode (in
Windows 95 or Windows 98). When PartitionMagic runs from DOS or from
MS-DOS mode, it does not need to be able to find the drive letter for each
partition. Thus, if the problem indicated by this error message is the only
problem, PartitionMagic can run successfully.
#120 The logical drive chain is incompatible
This error occurs under some operating systems when logical partitions are not
chained together in the expected order. DOS, OS/2, Windows 95, Windows 98,
and Windows NT require that logical partitions be chained together in ascending
order. Some other operating systems do not require this. For example, some
versions of the Linux FDISK utility chain logical partitions together in the order
they are created. This error message identifies a very dangerous situation; using
the DOS FDISK in this situation can cause loss of one or more partitions.
For solutions to this problem, see the instructions in “Resolving Partition Table
Errors” on page 114. If you decide to back up your data and recreate your
partitions, you may have to use the same partitioning program that you used to
create the partitions in order to delete them. Norton recommends recreating the
partitions with DOS FDISK or PartitionMagic.
#121 The first sector of the drive cannot be read
The first sector of the hard disk (cylinder 0, head 0, sector 1) contains the master
boot record (MBR) and the primary partition table. PartitionMagic cannot make
changes to this hard disk because an error occurred when it read the first sector.
See error #50 for information on resolving this error.
