Всё больше в моду входят твёрдотельные накопители информации, по-простому — SSD диски (англ. Solid-State Drive). Технический прогресс делает их всё более доступными для рядового пользователя, а производители всё увереннее заявляют об их надёжности. Преимущества SSD очевидны. Первое, что замечаешь после замены обычно жёсткого диска (НЖМД, англ. HDD) на SSD — скорость загрузки операционной системы и скорость запуска программ. Я в восторге от работы SSD.
Нет ничего вечного. Мой SSD не проработал и полгода. На днях просто завис компьютер. Намертво завис — в прямом смысле этого слова. После попытки его перезагрузить выскочила ошибка загрузки — типа, операционная система не найдена. Вот так я впервые увидел, как погибает SSD. Он просто перестал работать. Без никаких предвестников. Я несколько раз видел, как гибнут обычные HDD. Обычно предвестниками скорой гибели являются ошибки чтения/записи, устройство начинает издавать необычные звуки и т.д. Здесь же всё произошло без предварительных симптомов — в один момент. Опишу, как выглядит эта гибель в операционной системе Linux.
Первым делом подключил SSD через USB/SATA конвертер к работающему компьютеру.
Вот что увидел в dmesg в течение 30 секунд (спойлер):

Возможно, там не часы, а какие-то свои единицы измерения. Но и Power_Cycle_Count – количество циклов включения/выключения цифра 48169692 нереальная.
Использую утилиту cfdisk. cfdisk /dev/sdb — предлагает выбрать тип используемой таблицы разделов. У меня был dos:
Можно было бы попробовать его сейчас разметить, но в душе ещё теплится надежда восстановить информацию, по-этому, для начала, попробую использую TestDisk. TestDisk начинает сканировать. На 3-ем секторе пауза, затем сканирование продолжается. Программа завершает свою работу:
Смотрю dmesg — за время работы TestDisk высыпались ошибки (спойлер):

так же безрезультатно.
Анализируя ошибки dmesg, делаю вывод, что SSD отключается при попытке обращения к нему, о чём свидетельствуют строчки:

[ 2237.145182] usb 1-2: USB disconnect, device number 6все последующие ошибки — ошибки обращения к несуществующему устройству.
Надо попробовать подключить устройство к SATA, без посредников.

Да уж… не густо. И с паяльником не залезешь.
В заключение несколько советов/мыслей вслух:
Все пользователи компьютеров делятся на две группы: кто ещё не делает бекапы и кто уже делает бекапы. (есть разные версии этой поговорки).
- Регулярно делайте резервные копии важной информации. Приобретите внешний накопитель и периодически сохраняйте на нём информацию, которую будет жаль потерять. Каждый сам решит, что ему дорого.
- Используйте HDD, как дополнительный носитель. Не храните всё на SSD. Конёк SSD — скорость. Нет смысла хранить на нём архивы фильмов/музыки/фотографий. Используйте для хранения «больших и долгих данных» HDD.
- Максимально используйте SSD для системного раздела и файла подкачки (swap). Это значительно ускорит работу системы. Если носитель информации выйдет из строя — систему и программы всегда можно переустановить, это не занимает много времени. Я никогда не делаю резервную копию системного диска. Единственное, что сохраняю в резервной копии — каталог /etc. Всё остальное устанавливается и скачивается за несколько команд (я использую Linux. В случае использования другой операционной системы ситуация может быть иной)
- Подумайте об использовании RAID. В моём компьютере стоит дополнительно HDD-накопитель на 2ТБ. После этого случая я купил новый SSD на 120ГБ, из них отдал ~50ГБ под систему (/ — корневой раздел), остальное под раздел /home. На HDD создал раздел идентичного размера с SSD /home и объединил их оба в RAID-1 (зеркалирование) при помощи mdadm, а оставшееся место HDD примонтировал в /home/<username>/media. В итоге вся информация о конфигурации пользовательских программ хранится на RAID, а “большие долгие данные” в каталоге media.
- Возможно, есть смысл купить сразу два идентичных SSD и объединить их в RAID с зеркалированием. Скорость обращения упадёт незначительно, а сохранность данных повысится.
Спасибо, если дочитали до конца.
Не забывайте делать резервные копии.
