This software is a powerful and comprehensive tool for testing disk drives and NetWare partitions on Novell NetWare. Download an evaluation release supporting testing of the first 1000 MB or purchase a copy with no disk testing size restrictions.

Key Features:

  • Complete disk testing.
  • Multiple types of disk tests.
  • Supports various I/O block sizes.
  • Displays sequential and random I/O disk performance.
  • Extensive analysis feature including bit-walking.
  • Supports automatic HotFixing of defecting sectors.
  • NetWare Partition Verify detects areas of the partition that are already Hotfixed and verifies the HotFixed areas instead of the original sectors.
  • Detects errors in the System Data Area of a NetWare partition.
  • Displays NWPA and DSK drive details.
  • NetWare 3.x, 4.x, 5.x and 6.x.

This software runs as an NLM on a NetWare server. For NetWare 3.x and 4.x servers, both the NWIO (DSK) and NWPA (HAM) device driver interfaces are supported. For NetWare 5.x and 6.x, only the NWPA (HAM) interface is supported.

An option is provided to automatically HotFix defecting sectors. When media errors are detected, the sector will be replaced with a spare HotFix block.

The System Data Area is a very important part of the NetWare partition. If bad sectors are discovered in this area of the partition, the entire partition will fail in the future. This software will detect errors in this area, giving you advance notice that the disk drive needs to be replaced.

Various verify methods are supported:

  1. Read-Only sequential verify. This method performs a read only sequential scan of the disk drive. Various block sizes are supported from 1 sector to 512 sectors per I/O. No data is written to the drive. This method is also a quick method to determine the read performance of a disk drive.
  2. Read-Only random verify. This method performs a read only random scan of the disk drive. The software generates a random number that is used to determine the sector to read. Various block sizes are supported from 1 sector to 512 sectors per I/O. No data is written to the drive. This method is also a quick method to determine the random I/O performance of a disk drive.
  3. Read-Write sequential verify. This method verifies that data can be written to a disk drive and then read back. A data pattern that is unique to each sector is written to the disk and then compared on read back. Various block sizes are supported from 1 sector to 512 sectors per I/O. For this verify mode an option is to perform an extensive verify which writes multiple data patterns to the disk drive. This includes performing a bit-walk data pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions, volumes and data on the disk drive.
  4. Read-Write random verify. This method verifies that the data can be written to a disk drive and then read back. The software generates a random number that is used to determine the sector to write / read. Various block sizes are supported from 1 sector to 512 sectors per I/O. For this verify mode an option is to perform an extensive verify which writes multiple data patterns to the disk drive. This includes performing a bit-walk data pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions, volumes and data on the disk drive.
