is my C drive dying?

Thanks for the crash course! But VirusTotal gives 2 hits for this file... so I haven't installed it yet. BTW could you explain (briefly) the difference between cloning and restoring a drive? Another thing: I also have 2 external USB hard drives. One tested OK, but the other (Maxtor onetouch) isn't even detected by Crystal diskinfo. (it's still working ok though) I compared the SHA256 on my 2009 copy of hdtune_255.exe with a fresh download version, and they're the same. It's the same value as listed on virustotal. 4256abb5b5583aeb5c61937415555657a5ae3b76fcc59657ed fcb3bce792f958 My guess would be, a false positive. Here's a description of Trojan-Clicker. https://www.microsoft.com/security/p...:Win32/Agent.O I would not expect the second detection to be locatable in Google. I have HDTune 255 installed on just about every C: drive I've got. I sure hope it isn't infected :-) You would need an AV with known-good heuristic detection capabilities, to catch it in time. Seeing as the major AV products do not identify that as malware via its signature alone. Windows Defender hasn't flagged it, but then, WD isn't exactly bulletproof either. ******* "Clone" copies the content to a new disk. Windows assigns drive letters as they arise. Once the drive on the right-hand-side is booted by itself, it will become a C: drive. +-----+----+-----------------+ Clone +-----+----+-----------------+ | MBR | C: | System Reserved | --- | MBR | D: | System Reserved | +-----+----+-----------------+ +-----+----+-----------------+ Backup and restore, keeps a copy on an external disk for safe keeping. The restoration can be made to the disk of your choosing, by booting the Macrium CD and doing the restore from the external USB hard drive to the internal drive. In other words, the destination disk can be completely blank, and you can still restore to the destination disk. No OS is needed, because the OS is on the Macrium CD. That's why you always burn the emergency boot CD in Macrium, for this scenario of restoration. backup.MRIMG / \ backup / \ restore / v +-----+----+-----------------+ +-----+----+-----------------+ | MBR | C: | System Reserved | | MBR | C: | System Reserved | +-----+----+-----------------+ +-----+----+-----------------+ Both clone and backup/restore record... 1) MBR (partition table and boot code) (partition table modified, if partitions are resized) The boot code in the MBR is the thing that gets fixed if you "fixmbr". 2) Track 0 (i.e. the sectors next to the MBR, used by Linux) 3) Partitions, both hidden, foreign, and native/visible. Truly foreign partitions are transferred sector by sector. Recognized partitions, only the logical info is transferred, and the "white space" on the partition is not copied. The software knows which clusters contain actual live data. The boot.ini or BCD files (for boot management), may be edited for best customer flexibility. (No drive should go "Offline" on you.) If you clone disks with "dd.exe" for example, after you're finished, the destination drive could have an offline status. Modern clones are by no means, "absolutely identical". Far from it. They are "logically" identical and have the same function. None of your files get lost. There are no guarantees about any other aspect. Most modern cloning or backup/restore software is not good enough for usage in a Court Of Law. For that, you need proper forensic tools. 4) PBR. The partition boot stuff is copied as a part of (3). If the partition is resized, perhaps that requires modifying the file system header, but the PBR would be preserved. PBR is the thing that gets fixed if you "fixboot". Generally the PBR is in the partition with the "Active" flag set. So if System Reserved has the Active (boot) flag set, the PBR would be there. What I'm trying to say here, is they do surgical copying. Also known as a "smart" copy. They only copy things that absolutely need to be copied. Any white space not containing your files, that part is not copied. If you have a 500GB partition containing 20GB of files, then approximately 20GB of reads and 20GB of writes will be involved. The other 480GB of white space, will not be defined. This is why the backup or clone takes ten minutes, and not two hours. Backup/restore is not a good way to "wipe" a disk. If you want a forensically clean destination drive, use DiskPart and do a "clean all" to erase each sector on the destination disk first. After the restore of the 20GB of files, the other 480GB will be in an all-zeros state, and no old stale files can be recovered with Recuva or Photorec. ******* [None of the above, touches a Host Protected Area. Those need special treatment, if you happen to be using such a thing. An HPA is not part of any users normal work flow... It's an annoyance when writing up articles about disks :-) ] HTH, Paul |

Like cloning software, modern imaging software knows enough about modern OSs to give the option (usually the default) to only image the parts that had relevant data on. They usually also offer compression, which makes the image file even smaller, at the expense of some extra time while imaging and restoring. -- J. P. Gilliver.

We are talking about a typical user, not a specific user's computer.

I have restored more than once (successfully), but never used the "clone" option of Macrium yet. Glad to be of service (-:. I don't think I'd ever use clone myself, since my restores are only when things go wrong, which with modern hardware is (usually!) sufficiently rare that drive sizes have increased, so I'd be restoring to a bigger drive. -- J.

It's a small laptop; when I bought it, they were described as "netbooks", though that word has become unfashionable - though such machines (small laptops with only one main drive and no optical one) are still being made and sold - increasingly of late with SSDs or eSDs (?) as the main (only) drive. Maybe it's one of these: http://www.dell.com/us/p/inspiron-3050-micro-desktop/pd I assume from the name (I haven't clicked) that that's one of those micro-cubes. Maybe. But it wouldn't be my choice. No, not mine either. Nor that I don't think they're capable of being adequately-spec'd computers; just that the need to add keyboard, mouse, and in particular monitor rather defeats the attraction, and you might as well go for a laptop (or netbook), and thus at least have portability. -- J.
