I recently received a ThinkPad 755CE where the seller told me it needed a HDD replacement, because it died (those old IBM DHAA-2540), replaced with a spare Toshiba MK1301MAV (1.3GB) which had similar dimensions, the ThinkPad detected it.
Formatted and transfered the system (format c:/s) to the HDD, then copy Windows95 install files, using rawdisk access trick with VirtualBox.
ThinkPad detected it but no boot. Put a Windows 95 boot floppy disk to the ThinkPad and booted, i can access the drive and even i installed Windows 95 from it! no data errors whatsoever through the installation, but the ThinkPad BIOS still refuses to boot from thath hard disk after the installation.
What i'm could doing wrong?, i read in this forum those IBM DHAA had some proprietary IDE extensions for the ThinkPad for corporate security (AKA vendor lock-in) that prevent any other brand of HDD to work, i could be wrong, tried with slightly more recent models of IBM HDDs (DMCA, DTNA and DDLA) and nope, some of them suffers the same problem or the BIOS outputs 00174 error.
