摘要： Embodiments of the present invention provide a system, method, and program product for allocating a block of physical storage space on a write surface of a hard disk drive. A computer system maintains a write count for each block on the hard disk drive. After receiving an allocation request, the computer system identifies one or more candidate blocks of storage space on the hard disk drive that can be selected to fulfill the allocation request. The computer system determines an estimated write count and identifies one or more allocated blocks whose write counts are within a specified number of write operations of the estimated write count. The computer system selects a candidate block based, at least in part, on physical proximity of the candidate block to one or more of the allocated blocks whose write counts are within a specified number of write operations of the estimated write count.

摘要： Embodiments of the present invention provide a system, method, and program product for defragmenting files on a hard disk drive. A computer system identifies a plurality of movable blocks on a hard disk drive. The computer system categorizes each of the movable blocks into a category based on the write count of each movable block, wherein the movable blocks categorized into a first category have higher write counts than the movable blocks categorized into a second category. The computer system relocates the movable blocks of the first category to a first group of one or more adjacent tracks, and the computer system relocates the movable blocks of the second category to a second group of one or more adjacent tracks, wherein the first group of one or more adjacent tracks and the second group of one or more adjacent tracks share, at most, one common track.

摘要： A tool for notifying a recipient of an email message, belonging to an email thread, that a recipient address has been added to or dropped from the thread. Address fields of the email message received are compared to the address fields of the most recent prior email message in the thread. Addressed that are determined to be added or dropped are stored in the metadata of the email message received so the added or dropped recipient addresses can be accessed to notify recipients of subsequent emails in the email thread. The metadata of previous email messages in the email thread are accessed to notify the recipient of recipient addresses added or dropped between any two consecutive email messages in the thread.
