Is that out of courtesy, like not turning off the telly when someone is mid-sentence?I know but,ive never done that either eg computers, phones etc. As long as its not doing anything it's always been ok. I wouldn't pull it if the car were playing a track on the usb. Would stop it first!
FYI, any USB flash drive, Hard-drive, etc can be removed from any device without damage to the files they contain if the drive is formatted as either FAT, FAT32 or exFAT.Does anyone know how to safely disconnect a USB zip drive either after playing music from it of after transferring files onto the internal storage ?
