Лучшие программы для восстановления BAD-блоков жесткого диска

BAD-блоки — логически или физически неисправные сектора жестких дисков, чтение или запись информации на которые невозможна или затруднена. Возникают бэд блоки по различным причинам — из-за неосторожной транспортировки винчестера, сбоев подачи электроэнергии на устройство, внутренних ошибок управляющей платы/программы, естественного износа поверхности диска и т.д.

Можно ли восстановить BAD-блоки жесткого диска?

В некоторых случаях BAD-блоки могут быть восстановлены специализированными утилитами. Если же сектора повреждены физически, то восстановить их программно невозможно. В этом случае применяется метод переназначения адреса сектора. На каждом винчестере имеется специально выделенная область для подобных мероприятий. Пока эта область остается свободной, ее можно использовать вместо поврежденных секторов.

Таким образом, для восстановления BAD-блоков должно быть соблюдено одно из двух условий — либо неисправность носит логический характер, либо на диске имеется служебное пространство для переназначения бэд-блока. Но следует иметь в виду, что не всегда удается «вылечить» бэд-блоки, т.к. многое зависит от конструктивных особенностей винчестера, функциональности его встроенного программного обеспечения и множества других факторов.

Рассмотрим наиболее распространенные утилиты, позволяющие с некоторой вероятностью восстановить битые сектора жестких дисков.

Victoria HDD

В качестве опций такого сканирования в Victoria HDD предусмотрена возможность восстановления (Refresh), полного стирания (Erase) или перераспределения (Remap) битого сектора. Первая опция помогает устранить логические ошибки, вторая и третья — физические и не устраняемые (без уничтожения информации) программные неисправности.

Пользоваться программой достаточно просто:

Среди плюсов и особенностей программы Victoria HDD выделим:

HDD Regenerator

HDD Regenerator достаточно узкоспециализированная утилита, решающая одну единственную задачу — обнаружение и исправление BAD-блоков.

Пользоваться программой относительно просто:

Приведенная выше инструкция запускает сканирование поверхности жесткого диска с опцией восстановления бэд-блоков, начиная с самого первого сектора. Доступны и другие режимы работы.

Минусы программы HDD Regenerator:

Disk Revival

Программа Disk Revival позиционируется автором как инструмент для блокировки «почти» битых и/или медленных секторов жесткого диска. Т.е., по сути, утилита не восстанавливает бед-блоки, а «консервирует» их. Сразу отметим, что утилита не справляется с физическими неисправностями секторов, потому выше и было использовано выражение «почти битые» блоки. Тем не менее, подобные секторы зачастую помечаются (той же Victoria, например) как битые. И именно с такими — «не совсем» битыми — блоками и работает Disk Revival.

В целом процесс исправления программой медленных секторов можно считать восстановлением жесткого диска, т.к. имеющиеся на нем неисправные участки более не будут использоваться, а, значит, и исчезнут все связанные с наличием таких блоков проблемы.

Пользоваться программой Disk Revival достаточно просто:

Утилита Disk Revival обнаружит все медленные сектора на диске и заполнит их произвольными данными. Другими словами, бэд-блоки блокируются на уровне файловой системы.

Плюсы программы Disk Revival:

Минусы Disk Revival:

DiskGenius

Исправление проблем с бэд-блоками производится программой DiskGenius примерно также, как это делает утилита Disk Revival.

Положительные качества DiskGenius:

К минусам DiskGenius можно отнести:

Все рассмотренные выше программы предназначены для работы в среде Windows (если не брать в расчет загрузочные версии Victoria и DiskGenius). Утилита MHDD не работает из операционной системы (Windows-версия хоть и существует, но с ее запуском обычно возникают всевозможные проблемы). Программа первоначально создавалась и в данный момент развивается в качестве загрузочного ПО для тестирования, диагностики и восстановления жестких дисков.

Наибольшую сложность у новичков вызывает процесс запуска MHDD, всегда начинающийся с создания загрузочной флешки или диска. Здесь этот процесс мы не будем рассматривать, а приведем ссылки для скачивания необходимых файлов:

Далее останется загрузить компьютер с вновь созданной флешки и выполнить несколько простых шагов по восстановлению BAD-блоков винчестера:

О плюсах и минусах MHDD судить сложно, т.к. программа в одном случае идеально справляется со своей задачей, в других — даже не определяет жесткий диск. Здесь многое зависит от модели винчестера и конфигурации материнской платы.

То, что в процессе работы с винчестерами не используются всевозможные системные драйверы и прочее посредническое программное обеспечение (т.е. работа с накопителем происходит практически напрямую), делает MHDD очень быстрым и безошибочным средством, чего нельзя сказать о любых утилитах, запускающихся из-под Windows.
