This drive has two mode, Drive mode 1 and 2, for this operation. Drive mode 1 ------------ Select drive mode 1 when the function of the connected controller satisfies following two items. - Read or Write operation instruction after Drive Select must be issued after confirming Seek Complete signal from the drive. - Drive Select signal must be turned off when the drive is not accessed even if only one drive is connected. For this mode, the drive renews the compensation data after Drive Select signal becomes false. During this opertion, Seek Complete signal is false. Then the controller changes Drive Select signal to true, and teh read and write operation is executed after Seek Complete signal becomes true. Drive mode 2 ------------ When the controller does not have the the function of Drive mode 1, the drive detects the renewal requirement for the positioning compensation data, waits specific time, and stops sending data on MFM RD Daa Line and Index signal (because the controller that causes the serious time out error to count the Index signal is available to use). After that, the drive performs the internal seek for renewing the positioning compensation data, returns the original cylinder and resumes the transmission of Read signal and Index signal. ********************************************************************** I N S T A L L ********************************************************************** FUJITSU M2225D2/M2226D2/M2227D2 OEM MANUAL 41FH5021E-05 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | x x | | | | | | +------x------x-------+ | +-----+ +-----+ | +-+------x--x-------+-+ +--+ +--+ | xx | | x x | +---x--------x----+ x x The drive may be installed as figure above. In this case, installation horizontal rate shall be within 20 degrees. However, when inclines as the disk side comes lower side, installation horizontal rate shall be within 5 degrees. Never install PCA on the Top !!! Ambient temperature ------------------- The operating temperature range of the drive is specified at a dis- tance of 3 cm from the drive. The operating temperature should not exceed 45*C with considering cooling air flow. To satisfy above condition, the base surface temperature under the Ready condition should not exceed 60*C. The PCA should be cooled especially with proper air circulation in the cabinet. Cable requirements ------------------ The total control cable length in a multi-drive connection should not exceed 6m.

AC line noise ------------- To eliminate AC line noise, a noise filter of the specifications given below should be incorporated in the AC input terminal of the drive power supply. Attenuation characteristics: 40 dB or grater at 10MHz Circuit configuration: T type Media error ----------- Cylinder 0, Head 0 7 are defect free. The number of defect in the M222XD2 are as follows: M2225D2 ..... max. 25 M2226D2 ..... max. 38 M2227D2 ..... max. 51 Mean Time Between Failures (MTBF) --------------------------------- The estimated MTBF of this drive during its life time is 30,000 hours after an initial 3-month period. Mean Time To Repair ------------------- MTTR is the average time taken by well-trained service mechanic to diagnose and repair a unit malfunction. This drive is designed for a MTTR of 30 minutes or less. Service life ------------ Overhaul of this drive is not required for the first five year. Power loss ---------- Integrity of the data on the disk is guaranteed against all forms of abnormal DC power failure except a power failure during writing. Write Precompensation --------------------- Write precompensation is not necessary.
