Because of smaller platter(s), mobile HDDs generally have lower capacity than their greater desktop counterparts.

Such large platters were never used with microprocessor-based systems. Hard Disk Drive Definition They were still able to read and write the 720K diskettes, by slowing down the drives; and 360K disks by skipping tracks. The circuit board model 25136-* (where * is a revision number apparently) has a large IC in the center of the board which is PARALLEL to the 50-pin cable edge connector. Would be interesting to see some stats since, as you mentioned, they are pretty rare.

Typically, some of an HDD's capacity is unavailable to the user because it is used by the file system and the computer operating system, and possibly inbuilt redundancy for error correction the hard drive has 350gb of video and nothing else on it. Traditional HDDs have a couple of other factors that impact performance, such as the time it takes for the reader to position itself to read data from or write data to http://windowsrefund.org/hard-drive/3-hard-drives.php DJ Baby Boy 12:10 PM - 1 November, 2012 Millz right now I'm runnin two 1tb Scorpio blue internal raid 0 for 2tb and they are running great in both of
