Awsome stuff!

Thanks!

AFAIK the Maxtor XT8760S has that same head bumper that also likes to fall apart and allow the heads to fly off the platters.

Yeah, being the same chassis I'm sure of that. Unfortunately, the capacitor damage means it won't matter at all.

ExcelStor still exists as a company but no longer makes drives. They had a big contract with Iomega to make REV disk packs.

Interesting! I did not know that. What do they do now?

@bobjoe2827 Ай бұрын

On that SA-604 the failure is the front board (specifically the microprocessor is bad) so it should be an easy swap. The bottom board originally had a bad peripheral driver chip (for the spindle brake) that I fixed by grounding the Y input on that chip.

Interesting! Well, I have an entire spare drive from which to get that board.

It's actually not CM but SM as it is in Cyrillic.

Interesting, I did not know that. Is that the same for the EC5300? I wonder if that would make it easier to search for these drives.

@@TheDiskMaster Yes as they are both Bulgarian drives. It does help considerably to use Cyrillic characters when searching for data on them.

Wow you really have great luck finding Shugart drives, how many do you own at this point? Also you got two more 8" drives? You went from having none to having I think about four at this point? That is incredible! I hope you are able to eventually do something with them, as far as I know there are no videos of those drives actually in action. Might as well get the rest of the Q2000 series you are already halfway there at this point : ))

Four plus the 62PC, which has 8 inch platters in a non standard form factor. Unfortunately the Q2010 is hideously rare and people like to overcharge for the rest of the Q2000 series. I will probably never own a Q2020 or Q2080 at this rate. On the bright side, I have sourced a high current 24 volt supply which should be strong enough to run these drives.

@@TheDiskMaster Even the 62PC you think will be able to eventually spin? That is one of the coolest finds yet I think, I still can't believe you got a 62PC! Annoying that IBM made it a proprietary form factor though, but they seemed to like to do stuff like that for their hardware. I've never seen a Q2010 for sale and wonder how many of those are left. The prices that people want are indeed really high. Maybe eventually you can get the rest of them since you might be one of the very few people that have the knowledge and equipment to eventually do something with them. Glad to hear you have sourced a 24 volt supply! I look forward to seeing what eventually happens with everything!

@@cdos9186When the 62PC was introduced, there was no standard form factor or interface for drives. It was also intended to simply be a component of a larger unit, the IBM 3350 Direct Access Storage Device, which itself was only an external storage device for a mainframe. I know it will eventually spin because the spindle is just driven by a large 240V motor. It requires no control to operate at all. If the motor works and the belt is good, it will spin. Whether or not it will ever do anything else is unlikely. The Q2010 is just a single platter Q2000 drive. The Q2020 being two, Q2030 three, and Q2040 four. I think the Q2080 is somewhat different, though. Unless the others show up for dirt cheap, I probably will not even bother giving them a second look.

@@TheDiskMaster It is neat to think about if anything is stored on that drive, it is just a matter of accessing it but that probably isn't possible with how much work it would require to do. That stuff all seems long forgotten about and abandoned sadly. Would be really cool to hear it at least spin even if the actuator may never move again... Given they are all the same drives with less or more platters, that does make sense. I would be happy to at least see one of them work and the condition it is in when you do get it going. That certainly is a project though given how those also have those annoying rubber bumpers that will jam the actuator in place...at least the electronics are there for the actuator and heads so it will have a chance at going again and seeing what shape the drive is in mechanically and internally : ))

@@cdos9186Unfortunately, like I said, the Q2040 has severe damage to the control board. I am still seeking out a replacement. I doubt anything significant is stored on the 62PC, and even if there were, it would take a lifetime to actually retrieve and decipher it. It's just the mechanical portion of a mainframe storage unit - I don't have hardly any of the electronics that go with it.
