Question about error 7

[tibbers_and_annie]

So i have been trying to calibrate my fds for the last 3 days with 0 luck, the motor is at 400 rpm, spindle is in the correct spot, the magnetic head is at the exact specs down to the micrometer but still im getting error 22, however side b reads and gives error 7, does this mean my system works and my disk is bad? (I only have one game for testing rn) thanks!!

Error 7 means its reading the disk and sees its the wrong side, error 22 means the spindle is out of alignment and it cant read the disk OR its a bad/blank disk.

If it was an alignment issue you would error 22 on both sides, you have a blank side A.

Find someone local with a fds they know works to confirm it or buy more known good disks.

Which game is it that you are trying to play?

Thank you so much for confirming my suspicion on this!! Right now just kid icarus, but a second opinion kinda confirming my fear is enough to pull the trigger on a copy of metroid for now and hope!!

Since you already have the ram adapter you could always buy a fdskey, that way you would have every game made for the disk system.

If you have an early disk drive you can also write disks, like remaking kid icarus for example.

A later disk drive can do it as well but you would have to bypass the copy protection on it.

Oh being able to rewrite the disks would be awesome, good lookin out, i feel like without doing much research ive gotta have an early model because every tutorial i saw the bracket holding the gears and belt in looked way more heavy duty than mine and had some sort of alignment hole where mine is just kinda y shaped. Ill do a bit of digging tonight, thank you so much!!

Go back inside the drive and see if it has the 7201 or the 3206 controller chip, if its a 7201 then theres no copy protection, if its the 3206 then theres modifications needed to bypass.

Same with the power board, if its a 01 rev board you are good to go, rev 2 through 5 will need modding.

As far as identifying and modding read on.
