Низкоуровневое форматирование дискет
Добавлено: Вс янв 19, 2025 11:41 am
Написал программу для форматирования дискет. Кому надо, пользуйтесь. Форматирование со стандартным размером кластера 512 байт. Пользуйтесь с осторожностью, во время форматирования дискету не извлекать, а также не будет возможности восстановления файлов, дискета будет перезаписана.
