Hitachi manufactures most other drives with a PROM chip for the firmware (programmable ONCE).
The drives manufactured with PROM's can NOT be flashed. No how, NO WAY. Doesn't matter how many times you try, won't work, because a PROM can only be written to once.
This is like the difference between a CD-R and a CD-RW.
Why do they use a PROM instead of an EEPROM for most drives?
Simple...it saves them a few pennies per drive because the PROM costs less!!!

所以我看能更新我HP OEM 7K100的機會是非常slim了..= = 雖然都是"同樣的firmware",但是有些是EEPROM(多次更新,DIY可以),有些則為PROM(一次更新,出廠時)
So the final word is...let's pray!!! XD
