Thread: Ideas for how to make IDE drive write-able

  1. #1

    Default Ideas for how to make IDE drive write-able

    I have a Cordata PPC (8086 portable)...It has a Seagate ST-238 20MB hard drive. I can't format the drive or write to the drive in any way. Not sure of the reason, looking for a manual or a guess as to how to break through this write protection. I came upon a similar problem once when I had a Tandy SX-100 from a Hallmark store that was write protected (it was a public computer in the store for making greeting cards). There is a bank of switches inside the chassis 1-2-3 ON, 4-5-6 OFF.

    If I find the answer I will post an update.

    So you can read from the drive, right? BTW, it's not an IDE drive but rather an MFM/RLL drive.

    oops yes mfm! a ST-238

    It could very well be the drive is bad, but a lot of Norton/Spinrite work came up nothing.

    What's the controller? Does it have a custom ROM?

    The way we'd do it in the old days is to put a bit of tape over pin 6 on the 34-conductor edge connector. It then became impossible to write to the drive.

    Out of curiosity do you have an MFM cable you can swap out?

    But can you read from it? Does it have a good partition on it? Without a partition neither Norton nor Spinrite can access it. When you said you can't format it above, did you mean LLF? If not, you should try to LLF it.

    Yeah, check the cable first.

    Below is a photo I took in 2009 (pointing out pin 1 orientation on an ST-225 to someone).
    Understandably, I am in the "check the cable first" camp.
