synchronization problem

[vdragan]

Let me explain my problem which occurred several times (about 10 times). Every day when go from job I made backup files to my removable hard disc (120 GB), and when arrive home I take those file from removable disc to home computer. Sometimes it happens that those files are corrupted and vista at home computer (vista is also at job computer) is simply not capable to copy it onto own hard drive, and some time happens that those files are simply deleted. In case those files are corrupted, I'm not possible to delete it until plug-in removable hard disc to job computer and then delete it. In some cases I was not able to delete those file on neither computer and in that case I needed to reformat whole removable disc. Fortunately, I made backups on daily basis and this is not much trouble as it could be (only one-two hours loss ). My colleague had same problem several times with his synchronization and he also noticed that this happens when vista install updates while hard disc is plugged in. I think same, but not sure 100% in this. Does anyone had same problem?
