#45 CRC error in data
When PartitionMagic or any other program reads information off of a hard
disk, it checks the CRC (cyclic redundancy check) information contained in
each sector. If it performs a CRC test and the result is different from the
value stored on that sector, there is a CRC error. This usually means one of
two things.
• The file being read has become corrupted by some other means.
• A sector used in the file’s storage has become bad and corrupted
that part of the stored file.
The solution is to do a surface test to make sure any bad sectors are marked as
bad, then reinstall the software involved to ensure that files on the system are not
corrupted. You may also want to try running PartitionMagic with an /IRE switch.
#48 Sector not found
This error can be reported when a given sector cannot be read or written to.
There are many possible causes.
If you are encountering this error, make sure that your BIOS supports the
operating system and hard disk on the system. Also run a thorough ScanDisk on
the drive to prevent data from being written to bad sectors.
#49 Write fault
#50 Read fault
(The following information applies to errors 49 and 50.)
PartitionMagic is unable to write to/read from a specific sector on the hard disk.
Possible causes include:
• If your PC beeps or displays a black box in the middle of the screen, virus
protection is enabled in your computer’s BIOS. Disable virus or boot sector
protection in the BIOS.
• A virus protection application (which may be a TSR or DLL program) is in
use. Disable the application before using PartitionMagic.
• There is a bad sector on the hard disk (this is usually the case only with older
hard disks). Run ScanDisk on the hard disk to perform a surface scan to verify
the existence of bad sectors. If your drive has bad sectors, we recommend you
replace it.
• You have set up disk mirroring with PC-Tools. Disable the disk mirroring
option.
