Files Write Protected

I continued to have the same problem and eventually moved all the data off the drive and decided to just use it as a (probably unreliable) backup. To be clear, I have 7 drives plus a system disk on this machine. 3 + system are internal connected via SATA and four are external all via USB. I have two 1TB externals that have had no problems and an older WD 250GB that doesn't have the problem. None of the internals - all WD - have had the problem either. I suppose it's conceivable that it's mobo related but it seems rather unlikely. Further, it appears that johno7 is running a Seagate (?) so it's happening across manufacturers.

Can't wait to see this thread light up on October 23rd.

Further down the spiral...

I am now running Windows 7 build 7100

Ok this is my problem:

I have been using my Maxtor Basics Portable external USB Hard Drive(300GB) ever since the Windows 7 pre-release. I bought it brand new then.

Everything has been working fine. I have used the Maxtor Basics Portable to transfer files and store files with no problems. Until last week. When transferring a file to the Maxtor Basics Portable I got the message, "Disk is Write Protected".

I have tried all of the "fixes" in this forum and many other fixes as well. None of them worked. Ok here is the weird thing. On this laptop i cannot format, disk check(with fix errors checked), change permissions etc.

However, on my Acer netbook with the exact same Windows 7 build, everything is fine. I was even able to format my Maxtor Basics Portable after backing up all of the files on another computer.

I still am unable to write to my Maxtor Basics Portable and as this is my primary laptop it is necessary for me to resolve this issue.

I am running out of space in my laptop.

I look forward to your combined expertise and the solution to this ridiculous issue.
