Hi Mattis, all I can contribute here are german IS/M Manuals of my P8000 which state, that this IS/M is compatible to ISIS II 4.1. Most likely, this IS/M is just a copy of IS/M + modifications to the specific hardware. No idea how helpful german text is to you though But that is all I have

OK, detatching the power cord of the disk from my PC while running FreeBSD and reattaching it also brings up error code 4 on the next access. This does not happen with other drives. So it must be some sort of initialisation the OS or BIOS does which readies up the drive. Oliver Lehmann <l

OK, I just got my Logic Analysator and traced the communication on my PC while forcing it to do PIO instead of DMA. I then changed my AVR code to do the exact same commands and nearly the same timings and... nothing changed - the drive still responds with error code 0x04 after the read sector

Hi, I knew ST-251-0, ST-251-1 drives for ST506. Some time ago I've got a ST-251 labled "MLC-1". Does someone knows what the MLC stands for? What is different to the other ST-251 variants? It looks like a regular ST506 drive. Oliver
