Corrupt files on USB drive?
Hi and thanks in advance for your help.
I have a bit of an odd problem, I have an external USB 640gb hard drive (Freecom ToughDrive with Password encryption software removed using Freecom tool), I use it at home (on a new dell Windows 7 64 bit PC) to store all my data
If I take the drive into the office and plug it into my machine there (Windows XP) I can read all the files, copy them off, no problem, same with my Windows 7 (64 bit) laptop that I have at home as well and on my Mum's (windows 7) laptop.
The problem is that if I open a file on any of the non home PC's (a word document or a JPG etc) if I then save changes to the file, when I try to open it on the home machine it either says it is corrupted/unreadable or that in the case of a folder of documents I copied on yesterday in the office - that the folder contents were not accessible.
I have just tried opening a word (2003) doc that I saved on the drive in the office yesterday on my home machine and word shows that it is goobledygook, I have closed the file (without saving or editing on the home machine) unplugged the drive and plugged the drive into my windows 7 laptop and when I view the folder with the word file in, the file has now gone...
I have also noticed that when I have created this 'corrupted' file situation, when I then plug the drive into a different machine I get the windows "scan and fix" option. I have done that in the past and it has 'found' all the files that I corrupted on the other machines and stuck them in a $found folder as though there was actual hard drive corruption.
Until about 6 months ago I had a Windows XP machine and have been working with an external USB drive for years switching it between many different machines - I thought it was the drive (I originally had a freecom toughdrive 320gb) at first so I replaced that about 2 months ago when I realised what was going on but it hasn't made any difference.
Can anyone tell me what is going on and what I should do to fix it??
Thanks again
Matthew
