Installation direction ---------------------- The drive may be installed in one of 6 orientations, that is on any of its facets. Inclination from vertical should be less than 5*. Mounting screws --------------- Either side or underside mounting may be used. Standard drive use M3 screws but some special models and US versions use 6/32 UNC. Screws should not protrude from the drive frame by more than 3mm or damage may occur. Mounting Screws: M3 x 5mm#6/32 UNC, M3 x 5mm#6/32 UNC Frame clearance --------------- There should be a gap of at least 2.5mm between the drive and the system mounting frame on all sides to provide for adequate air flow. Grounding --------- The M29xx series drives use Magneto-Resistive (MR) heads and therefore require special handling considerations. Users must ensure that the DE casing is NEVER shorted to the computer system's Frame or DC Ground.

Fujitsu's latest technology, the MR (Magneto-resistive) head technology, has made it possible to store 3.1 gigabytes on the M2909 as well as 2.1 gigabytes on the M2903 and M2915. Advanced Technologies --------------------- The adoption of the MR head, PR4ML (Partial Response class 4 Maximum Likelihood) and 8,9 encoding/decoding enables the storage of much more data than was previously possible. MR technology employs separate read/write transducers, which allows MR drives to store nearly 300 megabits per square inch. PR4ML increases drive performance by allowing more data to be recorded on each track and sustained reads at 6.8 megabytes per second for the M2903 and M2909, and 8.7 megabytes per second for the M2915. 8,9 encoding/decoding code results in improved signal strength. Together, these technologies realise recording densities as high as 75,535 bpi for the M2903 and M2909, and 71,627 bpi for the M2915. Track density is also as high as 3,553 tpi, leading to large storage capacity, and with advanced "On the fly ECC" error correction technology, makes the M2903, M2909 and M2915 ideal for workstations, servers, disk arrays, minicomputers and mainframes. Rapid Rotational Speed ---------------------- The 3 gigabytes storage capacity model M2909 and the 2 gigabytes storage capacity model M2903 and the 2 gigabytes storage capacity model M2903 achieve a rapid rotational speed of 5,400 rpm and provides a fast positioning time of 2.0 milliseconds track-to-track, 10.5 milliseconds average and 22 milliseconds maximum, including settling time. As for 2 gigabytes storage capacity range, Fujitsu provides the performance-focused model M2915 in addition to the M2903. The M2915 achieves a more rapid rotational speed of 7,200 rpm and provides a fast positioning time of 2.0 milliseconds track-to-track, 9.8 milliseconds average and 21 milliseconds maximum, including settling time. The M2915 is especially suitable for client server, video-on-demand and transaction-processing applications. Various Models with SCSI-2 I/F ------------------------------ The M2903, M2909 and M2915 provide both fast narrow SCSI-2 and fast wide SCSI-2 interfaces. In each interface, single-ended or differential can be selected. Furthermore, models with various types of sector sizes can be chosen from, and a dual-port feature is available dependant on the user's requirements.

Any media defects that occur once the drive is installed should be marked as such by the operating system. Consult the system documentation for details of any defect management schemes available.
