Many of you have encountered Hitachi HCCxxxx locked drives which were previously used?in DVR. Those HDDs have different label with Elsil logo which is pasted above?original Hitachi. If you connect such drive to PC it won’t be recognised via standart device manager…
你們中很多人都遇到過在DVR中使用的日立HCCxxxx的硬盤驅(qū)動器。這些硬盤和原來的硬盤具有不同,在原來的日立的標簽上被貼上elsil標志。如果你把這樣的驅(qū)動器連接到PC上，它就不會通過標準的設備管理器來識別，下來我們一起來看一下這種日立硬盤數(shù)據(jù)恢復應該怎么進行。
Now we want to consider one of such examples and explain how to return it to normal conditions.
現(xiàn)在我們想演示其中的一個例子，并演示如何將其返回到正常情況。
At the moment we have faced only 3 models which were locked by Elsil:
目前我們面臨的只有3款，被Elsil鎖住的型號：
- HCC543216A7A380 – ?5432A7 ?160Gb
- HCC543225A7A380 – 5432A7 ?250Gb
- HCC545016B9A300 – 5450B9 ?160Gb
First 2 examples are related to Hitachi IBM-ARM architecture and last one is IBM.?Solution for all variants is similar but we will show both examples!
前兩個例子與日立IBM的arm架構有關，最后一個是IBM。所有變體的解決方案都是相似的，但是我們將展示兩個示例！
- Lets take a look HCC543216A7A380 firstly.
我們先來看看HCC543216A7A380。
After Power On drive is spinning well and quickly going?Ready state but utility can’t be started due the error message:
上電驅(qū)動器旋轉(zhuǎn)后，快速進入就緒狀態(tài)，但由于錯誤消息無法啟動實用程序：
Techno ?mode key....................................... ?: Error Error switching to techno mode
But drive initializes with correct ID. It means that SA is available and most probably not damaged!
但驅(qū)動器使用正確的ID初始化。 這意味著SA是可用的，并且可能沒有被損壞！
May appear that drive is locked by Password setting, but ?it’s not. To check it we can open universal utility:
可能會顯示驅(qū)動器被密碼設置鎖定，但它不是。為了檢查它，我們可以打開通用工具:
We suggest that drive is healthy and has no password so what is wrong? Answer is simple – inside NV-RAM there is a ‘locking flag’ which prevents normal HDD initialization thus?to unlock it we need to find this point and fix it. But how if utility even?can’t be open?
Here are the steps:
以下是步驟：
1) Unscrew PCB from HDA and connect to PC-3000. Wait until it goes DRD DSC and start ‘PCB only mode’:
2) Perform Rom and NV-RAM backup:
3) Open NV-RAM via HEX editor, press CTRL G and go to 0x0D7E?offset?then?change 04 ? 00
4) Save changes and write this new NV-RAM (Work with NV-RAM ? Writing NV-RAM)
5) Repower the drive, restart the Utility and enjoy. HDD is initializing correctly?for now with full User Area access (if there is no other problems of course)…
Don’t forget to perform full SA backup!
2. For?HCC545016B9A300 solution is similar with?2 differences only:
對于HCC545016B9A300解決方案類似，僅有2個不同的地方：
1) To operate with this drive or its PCB you should?use IBM (not IBM-ARM) utility and ‘Custom families’
2) ‘Locking flag’ is located??by another offset here. So when NV-RAM is saved and opened?press CTRL G and go to 0x001A?then change 0C 08 ? 04 00
Other steps are the same.
其他步驟是相同的。
It’s simple! Isn’t it? This is one of good examples when a few bytes can completely change drives behaviour and save your day also!
