Rotating the cable probably won't harm your drive, since the harddrive (fortunately) has circuitry that protects the electronics from this failure. (The protection is needed simply because you CAN connect it wrongly (do it on a PC and it won't boot either)).
There are typically a few things to try (they are in the order of how likely they are):
* Drive Partitioned? Take your WB3.0 disks and get hold of HDTOOLBOX. Divide your harddrives in to at least two partitions:
- "workbench" (at least 20 Megabytes),
partition device name: dh0
bootable
- "work" (the rest)
partition device name: dh1:
not bootable
* Drive formatted? Format the "Workbench" & "Work" partitions. (later copy the contents of a workbench disk onto the partition "Workbench". Later again copy the contents of the other disks into their respective folders (eg.: the contents of the fonts disk into "Workbench:fonts")
* Is the drive set as master? Somewhere on the harddrive there are jumpers, with which you can tell the controller how to handle this drive. If the drive is set as C/S (cable select) or slave it won't work. Cure? somewhere on the harddrive there is a diagram of how to set the jumpers (it varies greatly from drive to drive)
* Defective cable? Try another cable. Borrow one from a friend. Cure? Get another cable or try to solder it.
* Defective drive? Try your drive on another Amiga. Careful with this one: I have destroyed a controller on my A4000 due to a defective drive (this is however an unlikely event :-) ) Cure? Return the drive and get another!
* Unsufficient power? This highly unlikely, unless you also have installed an acceleratorboard. The power consumption could then possibly be so high that after spinup the system can't handle it. Cure? Another powersupply.
* Defective controller on motherboard of your Amiga? Try using a friends working drive, from a working system. Cure? Another Amiga motherboard! (This i almost impossible that it could be the trouble in your case since your Amiga is capable of booting up)
Hope this helps.
Cheers and good luck
