Just being curious - i´m struggling with the "Hotplug"- MethodJust being curious - i´m struggling with the "Hotplug"- Method in combination with an rather old USB IDE Enclosure (i suppose its from the early XP Times). Things i´ve done so far: While the XBOX HDD (WD80 with 10GB) is attached to it, things get extremely worse on my W7/Linux-PC. Its shown in the Device Manager/Drives as WD80, but not via WMIC, so Tools wont´t find the HDD at all. Hdparm (here /dev/sdc) would not resume and stalls the entire System. W7/Linux won´t shut down as long the Enclose is attached, neither does the PC boot (BIOS ginves me a B4 error, means USB Hotplug error). As soon as i power off the Enclosure/remove it, things will resume. Same happens when the drive is unlocked by the XBOX and hotswapped. But every other IDE drive in the Enclosure works fine. I understand that ATA Security could probably stall that old the Microcontroller in the Enclosure (somehow a 7.5 MHz RISC Controller), but i think as soon the drive is unlocked, this shouldn´t be a problem at all. -Or- the MC somehow resets the HDD again before it tries to obtain the drive data and the HDD is falling back to the point where ATA Security gets in Place, but i think the controller might have at least the ability to read out the drive data (Brand, Name etc) . Of course the Enclosure has always power while Hotswapping. Removing the jumper on the HDD (from Cable Select to Master) doesn´t do it. I got the Key for the HDD via my logic analyzer and its I2C Protocol Analyzer (Key has to be tried out). If things get completely worse, i could try to program an MC by myself and attach the drive to it in order to unlock it via Serial Commands (and remove the lock permanently, as well lock it again). But i think thats too much work. Done a AVR IDE/FAT32-Driver more than fifteen years ago (of course sources are lost by now), but somehow i won´t fiddle around again for only one purpose. I have another Seagate Spare IDE drive with 20 GB, which i could fit in the XBOX and try it to lock via the enclosure (if it does accept the command), but idk where or where to obtain the neccessary OS-files (including Softmod and the ability to connect to the XBOX via LAN/FTP, as well as a driver, wchih allows Access to a USB-Stick attached to a mechanically modified controller port). I understand that there have to be at least two Partition, C and E, but idk which FS (xfat?) etc. Any help is greatly appreciated ! Best regards Stef
