This just bricked two v59 hitachi drives of mine too,
Same thing, flash seemed to work, used connectivity kit, and after a reboot windows cant see the drive, it wont eject, and def wont work in an xbox.
Hey.. I had that problem and here's what U can try after using that buggy version of the flasher..
1- Turn the xbox on
2- Open the DVD tray
3- With the tray Opened, Remove the power cable from back of 360
4- Replug the Power Cable
5- Make sure the Sata cable is connected to PC and turn 360 on with Tray still opened
( without any Wire trick, connectivity kit Switch , etc..) It will get into ModeB due to
the firmware ModeB tweak flashed with the buggy flasher
6- Now, open Device manager and do a "Scan for hardware changes" and if u're lucky enough
winXP should detects it.
If U have it detected by winXP , be sure to use GaryOPA latest pack Xtreme v1.3 and flash the drive with it.
I used it and it rescued the drive by patching the correct Sectors & checking the flashed Firmware.
I reviewed GaryOPA's way of checking and patching the FW and this is really the best way to do it,
Greetings to GaryOPA for his excellent job in writing this package Xtreme 1.3, when someone want's
to help others by creating a batch file or a Windows Application,the first thing to consider is that the
process is doing exactly what it was meant for without any errors,because some situations cannot
afford foolish errors,and the GUI or the windows Front-End is the last thing to take care off...
