  Normál esetben így néz ki a lemez legelső szektora. GPT séma esetén is. Tehát ezt az 55 AA végződésű szektort kell megkeresni valahol lejjebb.

  válasz Doky586 #49948 üzenetére

  Sajnos arról nem tehetek hogy nem lát 2TB fölé, nem próbáltam csak ajánlottam. Most próbáltam egyébként működik simán a 2TB limit viszont sajnos megvan. Viszont csináltam neki egy image fált, amibe bele toldottam némi üres helyet, majd az egészet még egyszer saját maga után másoltam, és látott belőle mindent, viszont a free verzió limitált 512kbájt/s sebességre.

  Ugyanezt az image-t viszont a TestDisk is működésre bírta, csak az ugye nem tudja csatolni, viszont kimenteni ki tudja belőle az adatokat.

  Neten találtam és akár témába is vághat:

  I’ve come across a curious problem. I have a 2tb hdd in a caddy that I back up my files to. In the external usb caddy the hdd works fine and I can access and write files. If however I then put the drive in my pc…that is connect it through a sata port, windows says the file system is unreadable or corrupt and I need to format it. Then If I place it back in the external usb caddy, it works fine again. I’ve checked this drive running a drive checker and there are no problems with it. So why will it not read the disk when its connected via a sata cable internal??

  I format the new drives on the sata bus ,then they read write ok;I put them either in an usb icybox caddy and they behave weird, unformatted, or show two partitions whereas there is only one, or one active the other unformatted etc

  the same if I put the sata formatted drive in docking station pro, same behaviour

  it means that if you format the drive in icybox it will work, but it will not read on sata bus, nor on the docking station

  this is very dangerous because if your docking station model fails,and the controller inside is updated you will no longer be able to read this disk
  the docking station of 2011 behaves differently than the one from 2015
  western digital amsterdam in my case KNOW NOTHING about their own hard drives and cannot solve this very big problem !!!
  same for docking station pro importer in germany
  in other words, me as an amateur in relative terms, do not know less about hard drives then these socalled qualified people working for WD

  in general HOW to initialize format a new drive so that it can function in all the 3 media

  sata bus, icybox usb or other usb caddy and docking station, all have different controllers that see the hard drive differently

  but what is wrong digitally I am too stupid to understand because the internals of hard drives are very complicated, I do not understand these things

  Something similar that happened to Cosimo happened to me too, but with a Seagate enclosure. Everytime I put a HDD inside of that Seagate enclosure, it says “Not formatted”. OK, I format the drive in the enclosure, it becomes readable. Then I put it inside the PC, no formatted. Back to the enclosure… no problema.
  Then I do things the other way: Drive formatted in PC, put it inside the enclosure: “Unformatted disk.” That enclosure recognize the drives only if you format that drive previously in that enclosure. That happened not only to me, all my friends that have that type of Seagate enclosure (Passport) suffers the same. That is not nice. My PC is broken, beyond repair. I have only a laptop (no possibility at all to have a new desktop or repair the old one). I have a 3 TB HDD, with all my information (I cannot buy another HDD, I’m… literaly… too poor for that), my only option is to put that 3 TB HDD in the enclosure, but I cannot risk to lost my information. I used to have an expensive dock station (that somebody gifted to me), but do not last for too long, it is broken too. Blame Seagate, cannot they make a common enclosure? Damm’ market.

  I, too, have seen similar situations involving RAID. However, in my case, the RAID was for mirroring (RAID 1?), so a drive pulled out should be just fine. However, the RAID hardware would reserve the first few sectors of the drive for its own use, and the MBR would follow these reserved sectors. While the RAID knew about this, other systems would not, and would see the drive as being unformatted.

  If the old system (or one with a compatible RAID) is still available, the ones I have used all had a way to turn off these reserved sectors, so that the drive could be taken to a non-RAID system w/o losing any data.
