  • Then the cmos battery is probably in a Dallas DS1287 or similar chip. There are hacks to replace the battery itself with a CR2032 holder, but it requires drilling into the chip.

    I bought a DS12887+ to replace it, and socketed it in case it would need replacement again in the future (in another 30 years? :)). But if you want to go this route look up what chip is compatible with the exact one you have.


  • No, the reason it doesn’t work is that IDE to USB adapters don’t support pre-LBA HDDs. These old disks are all CHS-addressed.

    I wanted to take images of such disks. I ended up managing to boot an ancient version of Knoppix from a CD (just booting it was a nightmare) and then using dd_rescue to clone it to a file on a CF card connected vi a CF-to-IDE adapter.

    Edit: oh, drive powers off when usb is connected? Might be that the adapter doesn’t offer enough power, but if you could get around this you would inevitably run into the problem I describe above.
