The Orb Drive is a 3.5-inch removable-hard-disk drive introduced by Castlewood Systems in 1999. Its original capacity is 2.2 GB. A later version of the drive was introduced in 2001 with a capacity of 5.7 GB. ==2.2 GB drive specifications== This removable-disk drive is far quieter in operation than its contemporary, the 2 GB Iomega Jaz, and incorporates several notable and quite novel features: * For ease of working with an SCSI interface, the SCSI identity could be altered simply with a screwdriver. A recessed control located under the unit allowed one of four settings (0; 4; 5 or 6). * Unlike its rivals, the Orb has a protective cover over the front of the unit, completely encasing the data disk. Closure of the cover allows air to be purged for reading and writing operations. A button located at the centre of the front panel raises the cover for insertion or removal of a disk as shown in the picture on the right (97 mm wide × 103 mm high × 7 mm deep). Disks are fed into the front of the drive and pressed down lightly to engage them with the drive mechanism. Seconds afterwards the lid would flip back down. * The Orb is encased completely in smoked transparent plastic through which the power/activity light shines (steady green/flashing amber or flashing red) as disks are loaded, tested and unloaded. It is also possible to follow movements of the read and write mechanism through the top panel at the rear of the unit. Orb disks were made in Malaysia and Thailand and formatted for Macintosh or IBM compatibles. Disks arrived in a transparent plastic protective case which was shrink-wrapped and enclosed in a cardboard slip case. The drive, Model ORB2SE00, was made in Thailand and the power adapter Model 777-052000S-KF in China. It is compatible with what were then the contemporary PC and Mac hardware and operating systems viz: Intel Pentium, AMD K6, Cyrix MMX, iMac and Bondi-blue Power Macintosh G3, G4+, Windows 98 and Mac OS 8.5.1 with firmware update 1.1 et seq and Mac OS 8.6 onwards. During the Orb drive's general period of relevance, two different SCSI/USB adapter configurations were provided by Castlewood: # The first uses two adapters, one to connect the drive's female HD50 "SCSI IN" socket to a female DB25 socket into which a male DB25 plug to USB cable attached; # The second is Castlewood's own adapter "The ORB USB Smart Cable" Part Number 88205-001 made in Taiwan (Male HD50 SCSI to USB). This single unit has two manually operated locking pins to keep it firmly connected. The attached USB cable has a clear transparent cover incorporating eight toroidal ceramic surge suppressing magnets close to the adapter. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Castlewood Orb Drive」の詳細全文を読む スポンサード リンク
