I would like to elaborate on a new feature that we&#8217;ve added in this update. We call it <em>Media Map<\/em>.<\/p>\n<h3 style=\"margin-top: 1.5em;\">Media Map<\/h3>\n<p>&nbsp;<\/p>\n<p>The process of copying data from the source drive is very important in data recovery. But reading every sector of the drive is not always needed and sometimes can be even harmful, especially when condition of the device is getting worse with the lapse of time.<\/p>\n<p>Therefore, it is often reasonable to copy only the appropriate sectors \u2013 those which contain customer&#8217;s data and skip sectors which belong to the free space of the drive. Also it is often useful to manually specify regions which should or should not be copied.<\/p>\n<p>To make this possible, we introduce media map \u2013 the tool which has flexible means specifying sectors to be read.<\/p>\n<h3 style=\"margin-top: 1.5em;\">Filters<\/h3>\n<p>&nbsp;<\/p>\n<p>Media map is specified by a sequence of <em>filters<\/em>. Each filter can be used to include or exclude sectors from the map.<\/p>\n<p>Currently the following filters are available:<\/p>\n<ul>\n<li><strong>Partition table (MBR and EBR-s)<\/strong><br \/>\nThis filter contains sectors which make up a partition table: Master Boot Record and all Extended Boot Records.<\/li>\n<li><strong>Occupied space of partition<\/strong><br \/>\nContains only sectors which belong to files on partition. Deleted files and free space are not included.<\/li>\n<li><strong>All sectors of partition<\/strong><br \/>\nContains all sectors of the partition. This includes all deleted files and free space as well.<\/li>\n<li><strong>Entire disk<\/strong><br \/>\nContains all sectors of the device.<\/li>\n<li><strong>Custom range<\/strong><br \/>\nAllows to specify custom sector range.<\/li>\n<\/ul>\n<p><strong><br \/>\nExample1<\/strong><br \/>\nIt is needed to duplicate a hard drive with two partitions on it with minimum number of read operations. We define the following media map:<br \/>\n<span style=\"color: #666666;\"><br \/>\n<span style=\"background-color: #008800; color: #ffffff;\">(Include)<\/span> Partition table (MBR and EBR-s)<br \/>\n<span style=\"background-color: #008800; color: #ffffff;\">(Include)<\/span> Occupied space of partition0<br \/>\n<span style=\"background-color: #008800; color: #ffffff;\">(Include)<\/span> Occupied space of partition1<br \/>\n<\/span><br \/>\nBy applying this map, only sectors which belong to existent files will be copied. All other sectors will be skipped.<strong><br \/>\n<\/strong><\/p>\n<p><strong>Example2<\/strong><br \/>\nWe need to create an exact copy of source hard drive, but partition #2 does not contain any important data, so we&#8217;d like to skip the area that belongs to it. The following media map can be defined:<span style=\"color: #666666;\"><\/span><\/p>\n<p><span style=\"background-color: #008800; color: #ffffff;\">(Include)<\/span> Entire disk<br \/>\n<span style=\"background-color: #aa7700; color: #ffffff;\">(Exclude)<\/span> <em>All sectors of partition2<\/em><\/p>\n<h3 style=\"margin-top: 1.5em;\">Further development<\/h3>\n<p>Media map is a very flexible tool and we plan to evolve further. New filters which will allow copying by specific disk heads (or specific surfaces) are to be implemented.<\/p>\n<p>If you&#8217;d like to provide feedback or have a technical question, please <a href=\"https:\/\/atola.com\/contact-email?type=1\">contact us<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On September 15th, we have released a new version of Atola Insight Beta.
