| Opium Deactivated User 300 Posts 3/12 |  Posted - Mar 23 2012 : 2:32PMif my PC crashs while my external HD is on would any of my files get corrupted? i've been told by various people i should be safe unless i was playing a video or audio file when the crash happens and even then "most likely" everything should be OK. is this true?

| Opium Deactivated User 300 Posts 3/12 | Posted - Mar 24 2012 : 3:00AM last paranoid question: if my computer were to crash while file/files were still being downloaded to the external HD would that corrupt any other data on the external? Edited by - Opium on 3/24/2012 3:02:24 AM [Link] |

| Bill All-Star Member 5334 Posts 6/00 | Posted - Mar 24 2012 : 3:28PM For example, it used to be that you had to manually execute a process to reorganize your hard drive in order to free up space left behind by deleted files. Now that's done automatically. If your machine crashes while one of these applications is running, there is the possibility of data corruption. [Link] |

As has been stated, nothing on the external hard-drive itself has likely been harmed. Take the external hard-drive to another computer, and you will be able to see the drive and its files without a problem. Sometimes, plugging the drive into another USB port on the same computer will fix the problem (if you're lucky). I have drives that have both USB and Firewire interfaces, and have found that switching to the Firewire connection (assuming you were connected with the USB) also allows you to see the drive. I forget how I did this in the past, but the issue is really one of getting your computer to "forget" about the drive altogether. You then plug the drive back in, and you go through the whole "found new hardware" process again. [Link] |

| jrv Senior Member 1266 Posts 2/03 | Posted - Mar 26 2012 : 4:02AM Microsoft is close to release of their ReFS (pronounced "Reefers" I'm sure), perhaps this fall. In transactional mode, or whatever they call it, there will be no chance of data loss for any data on disk. linux is getting something called BTRFS (aka "Butterface") that is essentially the same thing. If they did it right it is also proof from damage. That may be a big "if". Sun's ZFS is likewise safe (and is probably the design point for ReFS, certainly the competitive point). It's now on FreeBSD and Macs. But, Sun designed for the enterprise market where they buy hard drives that work, not horribly broken USB disks. ZFS works great - I use it extensively - but not on USB disks. It's amazing to me that we are still today using filesystem architectures from the 1980s era. The transactional schemes can't happen soon enough. [Link] |

| jrv Senior Member 1266 Posts 2/03 | Posted - Mar 27 2012 : 2:36AM The features are neat, but filesystems are one of hardest things to get right in an operating system. The last time Microsoft tried a major new filesystem feature it was such a disaster they had to discontinue it after they couldn't fix data lossage (Windows Home Server). Hopefully management learned a lesson in that fiasco and won't go cheap in testing. There's no reason to wait on it this, but good reason to follow it and upgrade software once it works ... in 5 years or so. [Link] |
