leech Posted June 1, 2020 Share Posted June 1, 2020 Last time I tried to power mine up there was a spark and a piece popped off. Figured I would try to replace it and see if the drive would work again... Problem is it kind of burned and I couldn't read it anyhow. But here is the part that popped off, i believe it was a surface mount resistor. Quote Link to comment Share on other sites More sharing options...
Mehridian Sanders Posted June 1, 2020 Share Posted June 1, 2020 I will look through my collection and see if I have one. Sorry to hear about the fireworks ? . Quote Link to comment Share on other sites More sharing options...

I am just happy the TT didn't smoke too! I actually don't remember if this drive is my original Mega STe drive or not, because I swear that one died so it would no longer spin up. This one spins up, but then sparks and it won't detect. Quote Link to comment Share on other sites More sharing options...
MasterMotorola Posted June 1, 2020 Share Posted June 1, 2020 I wonder if it may be possible to remove the harddrive platers and transplant them into a working drive of the same type. This way you won't lose the data stored on them. 1 Quote Link to comment Share on other sites More sharing options...

So many of them show as untested and are 100 bucks on ebay though... Quote Link to comment Share on other sites More sharing options...

leech Posted June 5, 2020 Author Share Posted June 5, 2020 Ha, is there literally no number on either of those? Wonder if someone has the schematics or can measure that? Quote Link to comment Share on other sites More sharing options...

I was looking over the board, its an odd technology assortment. Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted June 5, 2020 Share Posted June 5, 2020 Possible that it is just so called resistor fuse - so very small value resistor. I had failure like this on my ST 157 (was with Mega STE) - burned down. After examining I replaced it with fuse and it worked. I need to dig out that drive (did not use it over 10 years) to see position of that component . Probably tomorrow .. Quote Link to comment Share on other sites More sharing options...

But here is the part that popped off, i believe it was a surface mount resistor. This is only a smoothing ceramic capacitor, I´m pretty sure it´s standard - 100nF (or 0.1uF) in 1206 package. I´m pretty sure that the issue is forced by a defect tantaluum capacitor right to the blown part. Tantaluum´s are well known for short circuits, smoke and sparks after years of non-usage, specially in 12 volt rails of harddrives and other stuff which draws relative high current when powered up. So replace the blown cap and the tantaluum right from the blown part also! General: It´s a good idea to set the "motor delay" jumper if the drive support this (search for datasheet). When power comes in, the high current draw is delayed and this prevents from this behaviour often. It´s not a cure-all, but I´ve done this since 10 years and since then no old harddrive went defect immediately after powering on. Quote Link to comment Share on other sites More sharing options...

I checked over my HDD's Only have stuff from the Apple II and Early Quantum Drives. I am sorry. Quote Link to comment Share on other sites More sharing options...
