Scannerz and Scannerz-Lite can be run on normally configured systems using Mac OS X versions 10.5 (Leopard), 10.6 (Snow Leopard), 10.7 (Lion), 10.8 (Mountain Lion), 10.9 (Mavericks), and 10.10 (Yosemite) using supported Intel or PowerPC processors using drives with SATA, IDE, FireWire, most Thunderbolt, and USB 2.0 (or greater) drive interfaces.  Both Scannerz and Scannerz-Lite are fully capable of handling Core Storage components, including  full volume encryption using File Vault 2 under Lion, Mountain Lion, and Mavericks, and Yosemite, multi-drive/volume virtual volumes using Core Storage, support for Apple RAID, support for most implementations of hardware RAID, and limited support for third party software RAID implementations.
Scannerz and Scannerz-Lite will not support any of the following types of devices:
               1. USB 1.0 or 1.1 devices, because the devices are so slow.
               2. Network drives, because they're too susceptible to network and connection problems
               3. Drives connected via Xsan or SAN, because so few of them are in use on normal systems.
               4. Optical drives of any type, because optical media itself tends to be the problem, not the drive.
               5. Very old hard drives using MFM and many SCSI interfaces, because they're rarely used anymore.
None of these devices should stop Scannerz or Scannerz Lite from operating properly, we've simply decided not to support them.
What is Scannerz?
Scannerz is a hard drive, SSD, and system testing tool. Scannerz uses a much more sophisticated scan technology than other drive testing products commercially available for Macintosh systems. With Scannerz, a user can identify not only bad sectors or blocks on a hard drive or SSD, it can also be used to help identify other problems that often act like drive problems, such as bad SATA or I/O cables.
Scannerz comes in the following three packages:
  1.    Scannerz with Performance Probe 2, Phoenix, and FSE or Mac OS X
  2.    Scannerz with Performance Probe2, Phoenix, andFSE-Lite for Mac OS X
  3.    Scannerz Lite
The Scannerz packages that include FSE or FSE-Lite, Performance Probe, and Phoenix, are referred to as the fully featured versions of the product, whereas Scannerz Lite is a less sophisticated subset of the fully featured version.
With one of the fully featured versions of Scannerz, you can:
  1.    Detect bad sectors/blocks on a hard drive or SSD
  2.    Detect weak sectors on a hard drive
  3.    Automatically diagnose problems with Scannerz new Diagnostics Mode.
  4.    Identify emerging system or drive related performance problems before they become serious
  5.    Isolate external and internal cable problems
  6.    Isolate certain logic board faults associated with the computers I/O subsystem
  7.    Using FSE or FSE-Lite, identify excessive drive access often caused by background (hidden) processes
  8.    Using Phoenix, create emergency boot volumes and do basic drive cloning.
  9.    Using Performance Probe, further isolate performance problems that may mimic drive problems.
All versions of Scannerz were designed to be very, very easy to use. All you need to do to use it is click on the drive or volume you wish to evaluate and start a test. We recommend using Scannerz or Scannerz Lite on a monthly basis so you can identify problems before they become serious, possibly even crashing your system. A comparison of Scannerz and Scannerz Lite features is shown in the lower section of this page.
All versions of Scannerz now have full support for Core Storage volumes available in Lion, Mountain Lion, Mavericks, and Yosemite, as well as full support for Apple RAID and most hardware implemented versions of RAID. All versions can perform tests on multi-drive/volume logical volumes under Mountain Lion, Mavericks, and Yosemite, as well as fully encrypted Core Storage volumes without the need for a remotely mounted drive or bootable volume. As of June 20, 2013, all versions of the fully featured versions of Scannerz (not Scannerz-Lite) come with our operating system tool named Phoenix, which will allow you to create an emergency boot volume to host Scannerz, create independent emergency OS drives, and copy (clone) your volumes.
From Simple Drive Tests, to Complex Troubleshooting, Scannerz Does it All
Scannerz uses the most advanced diagnostics in the world to check your hard drive while being easy to use. Typical users will find the drive evaluation process easy to use and understand. Advanced users will find Scannerz advanced diagnostics configuration and troubleshooting capabilities invaluable. Click HERE to see a tutorial on Scannerz basic operation.

System Requirements
Both Scannerz and Scannerz Lite can detect not only errors, but irregularities. Irregularities often occur when a drive or a subsystem component is in the process of developing problems. Scannerz and Scannerz Lite are the only commercially available tools on the market with this type of detection capability.
The fully featured release of Scannerz performs drive profiling, which can help the user clearly identify and head off problems related to a drive before they become serious by monitoring the historical performance of the drive and generating reports at the end of each test to indicate the current status of the drive. It also has three test modes named  Normal Mode, Diagnostics Mode, and Cursory Mode. Typically, you click on a few buttons to set up a test in Normal Mode, and if Scannerz finds problems or possible developing problems, it quickly evaluates them using Diagnostics Mode. A Diagnostics Mode test is fully configurable allowing the user automatically re-evaluate and thoroughly analyze problems. Both Diagnostics and Cursory mode tests can be manually configured by the user to run customized tests and perform advanced troubleshooting if needed.
Scannerz Lite, on the other hand, is a fairly simple and straightforward tool. It does a test over an entire drive or volume, and when complete it simply informs the user what the status is. There is no option to perform diagnostics or limited scans over suspected problematic regions, there is no logging window, and there is none of the drive profiling and analysis available with the fully featured version of Scannerz. Scannerz Lite provides a quick, easy, and low cost solution for someone that simply wants to ensure their system and drive are operating properly.

A Simple, High Performance User Interface
We opted to design Scannerz with accuracy, capability, and performance in mind at the expense of a more elaborate user interface.  Scannerz can detect both errors and timing irregularities which other products completely miss. Scannerz can automatically diagnose problems that other products can't even detect. If you want the most advanced drive and system testing tool on the market, get Scannerz.
Catch Problems Before they Occur
Scannerz can detect problems that are in the initial phases of development that other products costing three times as much often miss. Why wait for a catastrophic failure to occur if Scannerz can detect the problem before it becomes serious?
Test When You Want To
Scannerz allows you to stop, start, and resume a test when you want to. You don't need to tie your system down for hours on end just to test a drive.
Identify Bottlenecks That Can Act Like Drive Problems
The fully featured versions of Scannerz all come with Performance Probe 2, as well as FSE or FSE-Lite, depending on the package selected. Performance Probe 2 can allow you to observe system activity at a glance and track down many problems, including those that appear to be drive related but aren't. FSE and FSE-Lite are file system event monitors that can expose applications making excessive use of hard drives and SSDs, leading to a host of problems, such as overheating, excessive drive noise, and system bottlenecks.
Use Phoenix for Emergency Testing and Limited Recovery
Phoenix, which now comes with all releases of the fully featured version of Scannerz can extract the core operating system from a working volume and create an emergency boot drive, called a “Phoenix Boot Volume.” This can be used to launch Scannerz for testing in the event the main hard drive has problems, re-install the operating system without the need for media, and clone one volume to another. If a drive is partially damaged but can still be seen by the system, Phoenix can successfully clone off the good files to a good, working volume, leaving the damaged files behind.
