PCB failures (Such as Toshiba PCB G4311A<\/b>) affect thousands of hard drives every year and often result in permanent data loss. A hard drive may suddenly fail to power on, and a computer may not detect that it is plugged in. Some failed hard drives will also show up in computer BIOS with incorrect brand\/model information. PCB failures can also cause physical issues such as read\/write head failures, and many PCB failure symptoms overlap with the symptoms of other physical hard drive issues.<\/p>\n
Some emails from customers of Toshiba PCB G4311A failures are listed below, along with tips for replacing & repairing.<\/p>\n
Q: Toshiba MQ04UBF001 G4330A PCB<\/b><\/p>\n
Hello everybody I have an external USB 30 Toshiba drive 1 TB MQ04UBF100 with PCB G4330A Customer said he drop it The drive is clicking and not recognized (not even by Disk management) We went ahead and replace the PCB for a SATA compatible G4311A (thanks to you guys!) The ROM chip was also replaced We also got an exact match for a donor drive (an external USB 30 Toshiba drive 1 TB MQ04UBF100 with PCB G4330A) for head replacement- The hard drive doesn’t click anymore, the MRT application <\/p>\n
Q: TOSHIBA G4330A PCB REPLACEMENT<\/b><\/p>\n
forums, including this ( Toshiba MQ04UBF001 G4330A PCB , among others), I have not yet reached a conclusion from what I learnt, I think about two possible solutions 1) Replace the PCB For either USB or SATA compatible PCB (G4330A -> G4311A, USB to SATA, took from here Toshiba USB to SATA Guide ) The point is that I’m not sure wether it is plug and play, or it requires further manipulation as some posts suggest If PCB replacement is a simple issue, then I would go for this solution <\/p>\n
To repair a failure board, the simple way is swapping the failure board with a replacement board. Donor boards on HardDriveParts.com are listed below:<\/p>\n
