Good evening gentlefolks
For about two years I have been able to back up an SBS 2003 server disk image (using True Image 9.1) across the LAN to three 120GB Freecom USB Toughdrive hard disks that are mounted as an NTFS folder on a user's PC running XP Pro SP3 (one at a time, of course!) and are changed daily. One of these disks failed recently, and I replaced it with a 160GB Toughdrive. However, I have so far been unable to get the new disk to work with the server backup, nor will it work with the local backup that runs on the user's PC (True Image Workstation 9.1). All three drives have the "Optimised for quick removal" policy enabled.
I have tried Uwe Sieber's excellent USBDLM utility and initially it appeared to work, but now any time the new drive is connected and an attempt is made to use it a "Delayed Write" error appears within a few minutes; if even a simple text file is copied from the local disk to the Toughdrive the copy fails with a File Not Found error. I can browse to the drive and any folders and files on it, but I can't actually do anything with them.
The two original drives are still working perfectly for both the server and the local backup; unfortunately I can't remember how I set them up as it was quite a while ago.
I'm guessing that perhaps there are issues with Windows caching information for too long, or the mechanisms it uses for identifying devices and assigning resources; the problem is I don't know where to look in trying to resolve this.
Any help with this would be very much appreciated, as I'm certain that the remaining drives aren't going to last for ever.
