Help Can't find a doner replacement pen drive
Posted: January 18th, 2008, 15:19
A customer has asked me to recover important data from a 4gb usb flash drive.
It shows in Windows with device name and size but when I try to access the data Windows asks for me to 'insert disk'.
Software recovery options see the drive but show 0 bytes so can't go any further.
I've tried resoldering but still the same.
Led does NOT flash!
xtal tested OK.
It must be a faulty controller chip, I think.
Controller chip (its a new type for me) is a small rectangular shaped BGA chip. Not really possible to replace without infra red soldering kit. So I have decided the only way is to remove the 2 tsop memory chips with a hot air station and transplant them into a replacement drive.
I have tried to source a new replacement usb drive but can't find one the same. The original point of sale can't help. The one I bought in today looked the same on the outside but internally was VERY different.
Are there any other options or am I stuck?
