Error:You Need to Format the Disk Before You Can Use It

[prvnrk]

Hello Gurus,

I have a Seagate expansion 4tb usb 3.0 with NTFS partition (single) with lot of data. Today I suddenly received "You Need to Format the Disk Before You Can Use It" error and Windows 7 asking me to format it.

I know few tools like Active Partition/File recovery but in my past experience it recovered files with different filename (file type wise - not of much use). As I need to recover the data along with file names (if possible, same folder structure) so I tried Parted Magic as explained here at http://fixit.litten.com/linuxfilecopy.html but it is unable mount my 4TB drive and fdisk -l shows partition size of ~500GB (same with Windows disk management).

Code:

root@partedmagic:~# fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes, 312581808 sectors
Units = sectors of 1 * 512 = 512 bytes

root@partedmagic:~# mount /dev/sdb1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
root@partedmagic:~# mount -t ntfs /dev/sdb1 /mnt
NTFS signature is missing.
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
root@partedmagic:~#


Please advise, thanks in advance.

I have a Seagate expansion 4tb usb 3.0 with NTFS partition (single) with lot of data. Today I suddenly received "You Need to Format the Disk Before You Can Use It" error and Windows 7 asking me to format it.

If you put the drive back in its enclosure, your data should then suddenly reappear.

The firmware in the enclosure is configured for a sector size of 4096 bytes. When you remove the drive from such an enclosure and attach it to a SATA port on your motherboard, you expose its native 512-byte sectoring and render your data inaccessible. The partition table in sector 0 is still in the same place, but every other sector is out by a factor of 8.

Notice that the start and end of your partition are at sectors 2048 and 976752639, respectively.

976 752 639 x 512 bytes = 500.1 GB

976 752 639 x 4096 bytes = 4000.8 GB

Thanks Spildit & fzabkar for the replies.

@fzabkar - It's interesting and makes sense. Actually the problem is my drive was not at all being detected initially. As there're no physical damages, I thought problem could be with interface (USB to SATA converter of the enclosure) so I pulled out the SATA drive and used an external SATA-to-USB converter (not SATA directly as I don't have a desktop but only laptops) and it says to format the drive before using it.

So does it mean that Seagate enclosure's SATA-to-USB part/interface gone bad? if yes, can I get that alone replaced so I directly get ALL my data without needing for recovery?

Many thanks for all the help

if indeed the enclosure is the problem and nothing else
maybe you can even fix it by yourself (depends on your electronic/soldering skills)

Hello ,
Could You Take Out The PCB And Click Some Pictures And Show Us .Also Its Powered By a Adapter Or By Direct AC Voltage

It appears that your replacement USB-SATA converter is configured with a 512-byte sector size, so it is inappropriate. That said, intelligent data recovery software should still be able to recover your data in such an enclosure.

Does the drive spin up in its original enclosure? Did you use the wrong adapter on it, eg your laptop's 19V adapter?

If you connect the original enclosure to your USB port on its own (without the HDD), can you see it in Linux with lsusb? If so, then this will prove that the USB-SATA bridge is not brain dead. Be aware that some bridges will remain quiet if they don't detect an attached HDD, so this test may be inconclusive.

Here are some examples:

As already stated, detailed photos of both sides of Seagate's bridge PCB would help.
