Help to connect external hard drive
I currently use an old hard drive as an external, I bought a conversion
kit off ebay and all works fine. I have now taken the hard drive from an unused virgin top box and hoping to use that also as an external hard drive. Both are Seagate 3.5, Virgin one 500GB. I am assuming I would connect it to my PC and reformat. However I am not quite sure of the connections to make as they are slightly different to my current external one, as per image. Any help or advice would be good. https://imgur.com/a/BZmyhop |

Any help or advice would be good. https://imgur.com/a/BZmyhop I assume that adapter is a universal USB to IDE/SATA Your old drive is IDE Your Virgin drive is SATA The kit should have a SATA data lead and a SATA power lead and an adapter to convert from a IDE power connector to a SATA power connector. Looking at your picture the connector on top of the virgin drive looks correct. One lead from that will fit into the top of the large block with the USB lead. The other cable should fit to the power outlet from the power supply. Although not the same adapter the following Youtube video may give some idea https://www.youtube.com/watch?v=yGdbRI-WPcY or _some_ of the following https://www.youtube.com/watch?v=jGbrDoRWChk Your PC may not see a disk formatted in a Virgin box. A lot of PVRs are formatted as Ext3/Ext4. You may have to install a utility on the PC https://www.howtogeek.com/112888/3-w...-from-windows/ If formatting fails try the "HP USB disk formatting tool" https://www.bleepingcomputer.com/dow...e-format-tool/ https://kb.sandisk.com/app/answers/d...rd-party-tools By the way, also useful for reformatting SD cards that have previously been formatted for cameras. However expect some formatting of large disks to take VERY MANY HOURS perhaps all of overnight!!!! Even smaller sd cards can take hours. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Format it. If you use windows, use FAT or NTFS. For linux, FAT or Ext4. Make sure your data is backed up first, wiping the wrong disc is not impossible. NT |

I already have a 20GB external hard drive which I just update a few times a year, mostly pictures and a few excel stuff. Purely a back up should my PC fail, it is not permanently connected. This `new` one either goes to the skip or I try and use it as a back-up for the back-up. If I cant get it going then I can do without as most stuff is duplicated on the current external. I lost a lot of stuff a few years back when my PC failed, prevention better than a cure as they say. |

Of course it does.. recent ransomware encrypts the files as they are written so they are unreadable even if they are stored on a NAS. Its why you need backups from one NAS to another where the machine with the ransomware on can't access the second NAS. Then you can roll back to before the file was encrypted. |

Different people have different backup requirements. 20GB does seem absurdly small these days (even I have a 500GB backup drive), but perhaps he doesn't take many photos. People here and on the parallel thread "OT _ Back up Advice - PC" also talk about generational backups, incremental backups, protecting against a hardware failure while doing the backup, etc. Not everybody needs to be so sophisticated. An offline backup arrangement that will allow you to recover most files after a primary disk crash or ransomware attack is likely to be good enough for ninety per cent of non-business users. Most people don't even have that in place IME. -- Jack |

I did a couple of years back go through them and found loads of similar and badly composed ones, when on hols I probably take around 100 but only keep maybe 20 or so. I have a couple of spreadsheets that are important to me but useless for anyone else but I keep 3 copies stored elsewhere. |

Ok thanks all, I think I have got the connections sussed out now. The spare connections from the initial conversion kit connect to the `virgin` hard drive, I just wasnt sure what went where as it was different to my current external. Hopefully if it is coded to the box I can get that sorted. Hard drive wasnt coded to the box and all working fine, so thats me got a back-up 500gb external. |

Sorry but that's at least twice you've made this misleading statement about ransomware scrambling FATs. It's not the FS metadata that gets scrambled, it's the data stored by targeted file types that gets encrypted with a 1024 bit (or larger) encryption key regardless of the FS type. For example, all that's needed for a NAS disk volume's contents to be vulnerable to such ransomware, regardless of the FS used by the NAS box, is that it be mapped read/write to a drive letter on an infected MS windows client machine. I already have a 20GB external hard drive which I just update a few times a year, mostly pictures and a few excel stuff. Purely a back up should my PC fail, it is not permanently connected. Whilst a 20GB drive is laughably small by today's standards (what with the sweet spot price point now around the 6TB mark), only connecting it up to perform backup/restore operations a few times a year is an effective way to minimise the risk of its contents getting encrypted by ransomware. Note the use of the phrase, "minimise the risk". However, assuming reasonable vigilance, it's an effective strategy (a vigilant user would be extremely unlucky to be hit by a ransomware attack just when they'd randomly attached their backup drive for another session but sometimes, "**** (just) Happens"(tm F.Gump)). -- Johnny B Good |

I'm assuming your 'hols' last more than just three or four days and are in places of more scenic interest than your home territory. I can take 100 or more shots just on the trip to shore from the cruise ship in ports of call where the ship has had to lay off at anchor and provide a tender service (with maybe another 100 on the return trip from shore). Unless the excursion ashore is particularly lacking in scenic interest, I typically clock up a thousand or so stills and maybe an hour or so's movie footage to boot on each day's outing when on my 'hols'. Even day trips to local places of interest can produce a few hundred photos, including quite often some movie footage. You didn't happen to be involved in the recycling of all those expensively made Dr Who episode VTs by any chance? :-) -- Johnny B Good |

====snip==== Makes you wonder why the 3.25 SATA drives still need +12v & +5v Not 3.25, it's 3.5 (inch). :-) It doesn't make me wonder why. It's quite obvious if you give it any thought and remember that the larger internal desktop HDDs all use the power of a 12v BLDC motor to spin their platters at 5400, 7200, 10200 and even 15000rpm (though the advent of SSD technology has rendered those last two speed options obsolete now). The +5v (along with the +12v) are legacy requirements. Even though every SATA interfaced SSD drive I've seen have all been 2.5 inch drives and (just like their larger 3.5 inch cousins) are endowed with the +3.3v option, none to my knowledge actually utilise it as an alternative to the +5v line. At the very least, all SATA SSDs will run just fine off the +5v (and ground return) lines alone. There's no need to provide the +3.3v as anyone who has ever used a 4 pin Molex to SATA power adapter should be only too aware. If any of those power rails are eventually to become obsoleted, it's more likely to be the +5 and +3,3 volt rails, That "Legacy +12v line" will most likely become the 'defacto' standard for distributing DC power to everything in PCs and IT kit in general simply because of the ease by which the actual chip voltages required can be generated by commodity on- board dc-dc switching regulator chips. -- Johnny B Good |

More accurately, a SATA docking station, preferably one with eSATA and USB3 interface options. Rather conveniently, a SATA docking station will handle laptop sized drives equally as well as the full size 3.5 inch desktop drives. A SATA docking station or two makes a very cost effective data backup system since you can use a collection of 'bare' drives rather than a collection of 'bare' drives each fitted into their own individually purchased external USB/eSATA housings (or a bunch of overpriced 'readymade' external drives). It's also an obvious way to give your undersized retirees from your NAS box a second lease of life as archival storage backup drives. -- Johnny B Good |

Are you still using film? I'm assuming your 'hols' last more than just three or four days and are in places of more scenic interest than your home territory. No I bought my 1st digital from Kodak when mistakenly advertised at £100 instead of £300 so couldnt resist the bargain, I think it was 2002. Problem nowadays is we go for 2 x 2week hols each year and the most scenic thing my wife does is shopping plus she hates me taking her picture. I used to own a place abroad and had thousands of pictures but when I started going through them there was duplicates from one year to the next so deleted probably 60% of them. Current camera I got oct 2017 and have taken just over three thousand pictures but probably only retained a couple of hundred. I do have a suitcase full of film snapshots that I ought to convert to digital and save on my external HD. |

True, but higher psu voltage rails have some big plusses: they move more power per given cable & connector ampacity, and are less vulnerable to resistance, both fixed & unintended. NT |

This is already the case. Many servers are 12V only, or only have a small amount of current on 5V rails. Graphics power supplies are also 12V only - they have 3.3V from the PCIe connector but only at limited current. However the countervailing force is USB, which encourages 5V usage. It remains to be seen whether USB C will usher in common use of higher voltage USB (it'll go up to 20V). I think we'll see 12V for bulk power, and USB Power Delivery up to 60W (12V @ 5A), with 100W PD (20V @ 5A) reserved for more specialised chargers/docking stations. 5V will persist for lower power applications (eg USB lamps, power banks, etc) Theo |

Even then if I thought a scrambled disk was a possibility I would create a file called do.not.touch.me and test to see if it had changed and not do a backup unless I found out why.

Today it's common for the core of many large semiconductors to be running at 1V (or lower) and the interfaces at 1.8V. The 3.3V is kept for interconnects for legacy purposes. As technology moves on the required power supply voltages will be lower. Well, you've just stated the case for standardising on a single 12v rail voltage. The power demands of various devices can all be neatly serviced by on board dc-dc converters whatever their actual voltage requirements. It's already a long established technique for providing the dozens of amps at circa one volt or so to modern CPU cores as well as the 1.8v for dimms (and Gawd knows what else that happens to require a 'non-standard' voltage). So little of what's on board a modern MoBo these days uses the 5 volt rail directly that it might as well be derived off the 12v rail and any serious power demand on the 3.3v rail would be far better served by an on- board 12v to 3.3v switching converter anyway. As for the negative rail voltages, they were mainly used as low current biassing voltages. In fact the -5v rail disappeared from the ATX spec a decade or so back since virtually nothing used it even back then and any modern adapters that still needed a -5v rail simply derived it from the -12v rail using a low power analogue voltage regulator chip or a simple zenner diode and resistor. Anything that needs non-trivial power levels on a negative voltage rail can also be served by dc-dc switching voltage inverting regulators powered from the +12v rail. The +12v rail has always enjoyed a looser voltage tolerance spec (+/-10% as opposed to the +/- 5% tolerance of the 5 and 3.3 volt rails). This feature lends itself to the use of a 12v SLA as a simple battery backup for a 12v only system (10.8 to 13.2v) where a slight increase of the upper limit to a float charging voltage of 13.5v is unlikely to trouble the only kit that uses it directly, the BLDC spindle motors in desktop HDDs. The simplified +12v only PC power supplies will be both cheaper to implement and easier to design for the higher efficiencies required to qualify for the Bronze 80 and higher certification standards of efficiency. Once a roadmap to a single rail PSU powered PC has been published and a transition period agreed, we'll start seeing adapters advertised as being "12 volt ready!", possibly even being described as "12 and 15 volt ready!" to indicate that they can be used in the current multi-rail powered PCs and transplantable into a modern 12v only system PC. There's every good reason to eliminate the multiplicity of voltage rails between the PSU and the MoBo so I wouldn't be at all surprised to see such a transition wherein modern 12v only MoBos could still provide by default the original +5 and +3.3 volts in their PCI and PCIe expansion slots with a signalling system whereby a modern "12 volt only" adapter could negotiate for additional 12v power via these otherwise unused connections in the interface. This would allow otherwise expensive to replace adapters with normal power requirements to continue being used. Whether we'll actually see such a development in PC power standards remains, to my knowledge at least, an unknown. It just seems the most obvious next step for the manufacturers to take in improving reliability and reduction of overall production costs whilst meeting an ever increasing demand to reduce the energy consumption of desktop PCs. -- Johnny B Good |

The brand new 650W supply I bought a couple of weeks ago has numerous Molex connectors - still needed for additional case fans, a somewhat elderly DVD writer and a totally unnecessary case light.
