213MB SCSI hard disk.
Jumper Settings
J1 is the fifty pin scsi connector with pin 50 at the outside and pin 2 close to JP6. Jumper JP6 at the back of the drive between J1 and J3 looks like: 9 7 5 3 1 + + + + o + + + + o 10 8 6 4 2 This is how it is shipped from the factory. ++ indicates jumped, oo indicates open. Since you say that all of these are open, this is your problem: 9/10 determines Motor start with power - no wonder nothing is happening 7/8 determines parity - odd parity enabled is the default 5/6 determines bit 2 of the SCSI ID 3/4 determines bit 1 of the SCSI ID 1/2 determines bit 0 of the SCSI ID That is, it is shipped from the factory as SCSI ID 6. +--------+----------+-------+-------+-------+ |SCSI ID | Priority | 5 & 6 | 3 & 4 | 1 & 2 | | | | (MSB) | | (LSB) | +--------+----------+-------+-------+-------+ | 0 | Lowest |OPEN |OPEN |OPEN | | 1 | . |OPEN |OPEN |CLOSED | | 2 | . |OPEN |CLOSED |OPEN | | 3 | . |OPEN |CLOSED |CLOSED | | 4 | . |CLOSED |OPEN |OPEN | | 5 | . |CLOSED |OPEN |CLOSED | |x 6 | . |CLOSED |CLOSED |OPEN | | 7 | Highest |CLOSED |CLOSED |CLOSED | +--------+----------+-------+-------+-------+ The terminating resistors are the three eight-pin packs U40 through U42. These must be oriented with the dot towards J3 for the disk drive to work properly (assuming the drive is terminating the scsi chain) Jumper JP9, near JP6 and oriented at right angles, determines whether the bus is single-ended or differential. For signal-ended signaling, jump 3/4 and leave the others open. For differential, do the reverse. On the other LXT drives, 340/437/535, this jumper is called JP7. This will get you going. Here is a little information about the drive: Capacity Unformatted: per drive 248 MB per surface 35.4 MB Capacity formatted: per drive 212,703,232 per surface 30,386,176 Average Latency: 8.3ms Seek time: (ms) single track read 3.0 (other LXT drives are 2.5) single track write 3.0 average seek 15 (437/535 drives are 12ms) average seek to read 15 average seek to write 15 full stroke 30 SCSI overhead 0.5ms SCSI Transfer rate Buffer to host Asynchronous 5MB/s Synchronous 5MB/s Buffer Size 32K (other LXT drives have 128K) Cylinders per zone Sectors per Track formatted disk data rates: Physical Logical Physical Logical Zone 1 1.69MB/s 220 214 56 55 2 1.60MB/s 220 219 53 52 3 1.47MB/s 220 219 49 48 4 1.32MB/s 220 219 45 44 5 1.23MB/s 220 219 41 40 6 1.01MB/s 220 219 34 33 Tracks per zone are 1505 in zone 1 and 1533 in all others.
