The preferred embodiments described herein provide a memory device and methods for use therewith. In one preferred embodiment, a method is presented for using a file system to dynamically respond to variability in an indicated minimum number of memory cells of first and second write-once memory devices. In another preferred embodiment, a method for overwriting data in a memory device is described in which an error code is disregarded after a destructive pattern is written. In yet another preferred embodiment, a method is presented in which, after a block of memory has been allocated for a file to be stored in a memory device, available lines in that block are determined. Another preferred embodiment relates to reserving at least one memory cell in a memory device for file structures or file system structures. A memory device is also provided in which file system structures of at least two file systems are stored in the same memory partition. Additionally, methods for permanently preventing modification of data stored in a memory device and for identifying memory cells storing data are disclosed.

Method for identifying memory cells storing replacement data on a memory device

The preferred embodiments described herein provide a memory device and method for reading data stored in a portion of a memory device unreadable by a file system of a host device. In one preferred embodiment, a memory device is provided comprising a first portion that is readable by a file system of a host device and a second portion that is unreadable by the file system of the host device. The first portion stores program code operative to enable the host device to read the second portion. In operation, after the memory device is connected with the host device, the program code is provided to the host device, and the host device reads the data stored in the second portion of the memory device. Other preferred embodiments are provided, and each of the preferred embodiments described herein can be used alone or in combination with one another.
