- #1 [阿福], 19-11-11 21:51我部Mybook 4TB USB HDD突然死亡,我覺得係control board 問題,內裡data唔重要,唔想用高價去recover。睇youtube有教換control board同transfer firmware,想買黎試下自己換提高下知識。ebay可以買到,想知香港有冇得賣。
- #2 [呀金], 19-11-11 22:02買同型號pcb,換番舊板嘅firmware上去,成功機會很高。
不過我未試過。 - #3 [cornercube], 19-11-11 22:18我以前試過,
兩個同型號,
就咁 齋換塊好板落去 唔work...

唔怪之得.
Thanks! - #6 [alexanderkoo], 19-11-12 06:23How to open a sealed WD external HD?

- #8 [alexanderkoo], 19-11-12 06:52Mybook is 3.5" which can be opened easily. My passport is 2.5" which can't be opened.

- #10 [阿福], 19-11-14 19:29原來淘寶有得賣,仲好平。
- #11 [alexanderkoo], 19-11-15 07:37But you don't buy a brand new one to get the PCB board for swopping, do you? More than a decade ago, bought a used one at $50 for swopping, fortunately, successful.(no swopping of eprom) PCB board alone can be found on Ebay(must need the same model no. and with closer serial no). Not cheap at all.
There are other problems associated with a HD, such as click of death, corruption of boot sector. If can be read during POST, chance of PCB failure is low. I did open up a HD to swop the pen but not successful.(could not read)
The simplest fault is pen being stuck on platter especially power off whilst reading, simply open up, rotate the platter counter-clockwise and let the pen park once again. No fees but should clean up the platter with isopropyl alcohol and blow off all dust. Just for experimentation.(assuming total loss for unimportant data)

- #13 [純情小花], 19-11-15 08:04保安太強,我唔建意私人用 WD 外置 HDD,DIY 會冇咁煩。
- #14 [alexanderkoo], 19-11-15 09:06佢塊死人版有hardware encryption
Is it inside the Eprom which is modified upon utilization, hence needs swopping? No other components I can think of to store memory.
Got a de-soldering gun(may not be applicable) and a thermostat controlled soldering iron, I have confidence in desoldering/re-soldering the 8 legged eprom. Much easier for SMD, just build up a pool of flux to remove the component as quickly as possible.(someone uses a looped wire for even heating but a bit clumsy) Use a plier as heatsink.
最後修改時間: 2019-11-15 09:06:48 - #15 [阿福], 19-11-15 11:42encryption係由USB-SATA轉接板做,我覺得隻碟轉速好似唔足夠,淘寶三十幾元一塊,control board只係換firmware chip, 值得買黎玩下。
- #16 [alexanderkoo], 19-11-15 13:11Simply connect SATA direct after taking out the HD casing.
- #17 [阿福], 19-11-15 13:41#16
it won't work that way because the data is encrypted by the USB-SATA bridge board. - 返回 ...
