SubrosaSoft bietet unter http://www.subrosasoft.com/thestore/product_info.php?products_id=3 den DiskGuardian an: Backup/Restore Create a bootable copy of any operating system from any kind of media. This allows you to create an exact byte-by-byte replicate of any mounted local volume (including OS X startup disks, CD's, DVD's, etc), and a feature to restore these mirrors back to a volume. This uses a fault tolerant copy methods so it can be used to recover data from drives that have hardware faults, such as scratched CD's, or media with faults on it. Volume Repair Repair most hard disk faults. An advanced diagnostic and repair tool which will detect and fix most errors on a volume, and can enable and disable Apple journaling. Apple's new journaled file system keeps a log of the hard disk's main data activity. In the case of a crash or other system failure, the file system can retrieve lost data by consulting the "journal" log, restoring the system to its previous state instead of having to go through the lengthy process of rebuilding it. It is important to note that enabling Journaling can potentially slow disk access time down by up to 10%, but can be preferable in situations where data stability is more important than disk access speed Benchtest A full benchmarking suite. This is a full benchmarking suite with saved results from other Macintosh systems, allowing you to test your system against others. Hardware Integrity Thoroughly test all of a disk's data, and data space. This performs long term speed testing and throughput measuring, it is intended for finding intermittent hardware faults. Surface Scan Test every available part of a disk's surface. This performs a surface scan (reads all blocks) of a volume to ensure that there are no media faults (this works on any local mountable disks, all interfaces (ATA/IDE, FireWire, etc) are supported). Settings Configure DiskGuardian. Configure scheduling for DiskGuardian. Setup your eMail, FTP, or Webserver addresses for the optionally used reporting feature, and edit the display characteristics of DiskGuardian. S.M.A.R.T. is a widely supported standard in IDE hard drives. The technology was created and adopted by the disk industry due to the understanding that most hard drives sometime fail, and that it is usually possible for a drive to be able to predict that it will fail before it does, by monitoring various aspects of itself such as its motor, media heads, spin up time, and other manufacturer-specific parameters. The S.M.A.R.T. software built into DiskGuardian asks the drive's on the computer for their S.M.A.R.T. status every 5 minutes, and alerts you if a problem has been detected. DiskGuardian's version of S.M.A.R.T. (Self Monitoring, Analysis and Reporting Technology) transparently checks the health of your drives from the time your computer starts up, until it shuts down. The S.M.A.R.T. check is always running in the background, and DiskGuardian will be started automatically if a problem is detected. S.M.A.R.T. checking does not affect on the performance of your drive (as may be determined with the "Speed Test" feature in DiskGuardian), and the always-running background helper program that does this checking is very lightweight, and uses very little resources. Genau so interessant ev. CopyCat X unter http://www.subrosasoft.com/thestore/product_info.php?products_id=413 angeblich doppelt so schnell wie Carbon Copy Cloner. Die Teile kosten zwar was, man kann sie downloaden und ich werde sie mal antesten.
