Hi all, I was copying 2 files from 1 computer (98SE) to a flash drive plugged into another (XP Pro), one of over 500mb and the other over 200mb. My son was playing a flash game on the XP. The flash drive had been shared about 15 minutes before this and the XP had not asked to be restarted. The flash drive is an Imation 1Gb Cool. Somewhere between the transfer of the 500Mb file and starting on the next one, the XP computer restarted without warning. When it restarted, I tried again to copy the 200mb file but was told the disk was write protected. We tried to check that all sharing and permissions were correct but discovered that sharing had disappeared from the context menu. Poking around didn't find anything wrong so I decided to run the Network Setup Wizard, and found that we needed to change the workgroup name back to what is was before and turn on file sharing again. This done, I found that the shares that had been set up still existed, including the flash drive. However, the flash drive is now write protected and I can't find any way of changing this. Help! I have no idea where to go next and have already spent a frustrating afternoon with the computer that the flash drive was getting files from either struggling to network or crashing. It's taken me about 2 hours or more to this point and I still haven't done, nor know how to get the write protection off, so I'm hopeful that someone will be able to figure out what I should do to fix it. We run security software on all our machines and have a modem with router so I don't think we're looking for malware. But I could be wrong, I know! I'm sure there will be things that I left out that people want to know such as Ad-aware, Spybot, Zone Alarm Free (oops, forgot: it was playing up badly and had to be removed and hasn't yet been replaced), AVG Free. Anyway, anything else I forgot, please ask. I feel a bit brain stupid and frustrated after my battles this afternoon and don't think I've included everything that should be. Thanks people.
