I have a mac running OS 10.6.8 and when I plugged a flashdrive and external hard drive into it they worked fine, but when I unplugged them and put them into my Windows computer it says that they are write protected. I have Googled and tried to figure it out but I can't seem to get it so I can write on my Windows PC. The boot drive for my mac I found out is also a little bit messed up, when I checked it in Disk Utility it said that it needed to be repaired, so that might have messed up my drives. I can't repair it though, for some reason, but I have another mac that I can use.I had a sandisk ultra 32gb and external Seagate 500gb drive that are now write protected on my Windows computer, but readable and writeable on my mac. Please help!
