How does an operating system react when it tries to read or write to a bad stripe?
When the operating system attempts to write to a portion (a stripe) of a logical drive that has an entry in the BST, the write fails and an error code is returned to the operating system. Some operating systems can handle the error by using a write/reassign command that will write the data to another area of the logical drive. The new data will be stored at another location of the drive, but the BST is not changed. When the operating system attempts to read from a portion (a stripe) of a logical drive that has an entry in the BST, the read fails and an error code is returned to the operating system. There is no operating system recovery, since the data is lost. Each operating system will react differently when bad stripes entries occur. It is not possible for Adaptec to identify which files are located within a blocked stripe. This fact may lead to varying operating system behaviors. If the blocked file is a data file, the operating system will likely complain that it cannot find or ca
