I am new to the forum and thought I would share my experience with adding a hard drive to a Megafile 44 (MF44)
I scoured the forums and found vague instructions, incomplete instructions and instructions that were downright wrong.
This setup even works with a Megafile 30 (MF30) as the first HD in the chain. An additional option could be to use a SCSI to SD adapter and put an SD card as the second Hard Drive instead of a real Hard Drive. I think I am going to try this.
This is not a screw by screw description because if you are willing to open your MF44, then you know how to accomplish everything in my explanation.
1.Open your MF44 and remove the shielding. You will notice there are two 50 pin headers one of which the SyQuest 44 (SQ44) is plugged into. The other one is empty.
2.You will also notice there is a bracket that seems to be specifically made for adding a hard drive along with an additional power plug and an activity light plug for a HD. If your HD power connector comes straight out of the back your drive, it may not fit when attached to the bracket. I also tried a 90 degree power extension and it was still too large to fit. So, I zip tied the HD to the bracket, seems solid enough. I believe removing the power socket and soldering a "power extension tail" directly to the Hard drive may work. I have not tried this.
3.Make sure that the SQ44 drive is set to drive Unit 0 and the HD you are using is set to unit 1. There is nothing else to do with the SQ44 drive. Leave it where it is.
4.Remove the mounting bracket from the chassis and mount the HD to the bracket, but do not mount the bracket back to the chassis yet.
5.With an additional 50 pin ribbon cable, attach it to the HD and the empty 50 pin header, pin 1 to pin 1 of course.
6.Connect the power and the activity light cable if your hard drive has pins for it. It is not necessary to connect the activity light cable for this set up to work.
7.Mount the bracket to the chassis (If your HD power connector comes straight out of the back your drive, it may not fit when attached to the bracket. see #2 above) replace the shielding, screw the case back together.
8.There are dip switches on the bottom of the MF44, turn 1 off, turn 2 on and turn 3 off.
I used HDDriver 10.03 and both drives show up. You can also test before putting everything back together to make sure the drive you are using does not have parity enabled. It will not show up if parity is enabled.
