    Hi, I connected my windows removable disk to my colleague's mac to transfer some data. Accidentally her system started a time machine backup on my removable disk. Although we stopped it during middle of the process, now my disk is no longer recognizable in windows and all I can see under a mac system is her backup file.

    The process took a very short time. I wonder if it has deleted everything. Is there any chance I can get the overwritten data back? They are very important to me.

    Besides, is it a common problem of time machine backup? It is too dangerous for the removable disks.

    Accidentally? She would have had to actually reformat the drive to use it with time machine.

    Assuming your drive wasn't already HFS+ (which I'm sure it wasn't), then unfortunately your drive has been reformatted.

    Maybe talk to a professional recovery firm? I don't know if that is even possible, but it's worth at least asking a company like that.
