Maxtor XT-2190 MFM Hard Drive Reading

In an effort to read data from one of these MightyFrames, we are setting up other machines to read these hard drives:

From Al Kossow 8-28-2014:

You should try to figure out how to get block-level dumps of the disks in the

systems that you have.

It would be interesting if the 3B1 disk controller could correctly handle reading

Miniframe disks at the block level, but it's probably safer to try imaging the disks

that you have by finding another MFM disk, installing a system on it from the cart

bits, and copying off the contents either serially or out to tape (likely you're going

to have to fix the rubber roller in them) which could then be read on the Unix box

that you wrote the cart on.

From Al Kossow 9-3-2014:

just a FYI, an alternative once it gets going for a real mfm drive

interesting that it's been tried on a 3B1

(Our note:  We ordered 2 of these boards from David.  We will update this post with the status on our success with it.)

And the Kryoflux tie-in

And sometimes this will cross over into the MFM hard drive reading section:

MFM Hard drive Geometry/History

Devin2277 seems to "Test" a lot of MFM drives for YouTube, and every other drive he can find.

And what's that book he's referring stuff in?

And back to reading now...these guys are really smart:

I used an RLL controller on an MFM drive
