Fundamentals: Ok, you can flash your drive under DOS using version 1.69 or higher of MTKFLASH. The latest version is v1.80.1. You can download MTKFLASH from a number of websites; it's free. Just ask Google (or any other search engine) for a link.
From the Dangerous Brothers' site here you can download several rpc1 (= region-free) firmware versions for your drive. The files come with a Windows flasher which I wouldn't even attempt to use as your drive is not recognized by your Windows. I'd just extract the bin firmware file and let MTKFLASH play with it.
Procedure: First, in the BIOS - disable the IDE port where your dead drive is connected to. This lets you boot into an OS again (DOS or Windows).
Then, search this forum for MTKFLASH and/or dead drive - you'll find some vital info about MTKFLASH parameters and switches and how to set them when calling up MTKFLASH. Read Marco BTC's first aid kit for the 1004IM - most or all of it should apply to your drive also. I believe it's a sticky.
Third, download MTKFLASH and the firmware you're planning to flash. You could also, by e-mail, ask BTC support for a copy of their DOS flash package (unless I'm mistaken, it will contain MTKFLASH and the current firmware in form of a hex file).
Fourth, reboot into DOS and flash your drive. Good luck.
