Din cate inteleg eu de aici:

This is quite interesting:

===================================================================
Linux notices that the device returned 0xffffffff as the capacity in
response to a READ CAPACITY(10) command, so it tries a READ CAPACITY(16)
command, which *fails*.
So even under Linux you aren't getting the full capacity of your device,
you're only getting 2TB.

si din faptul ca la mine nu am nici un "READ CAPACITY(16) failed" ci
"SCSI device sdc: 5370855424 512-byte hdwr sectors (2749878 MB)", ce
inseamna ca a mers,
inseamna ca e problema de fdisk, cfdisk, sfdisk: astea 3 zic ca am disc
de 0 octeti.
parted vede discul, nu comenteaza la "mkpart primary ext3 0 2622488",
dar la "print" zice ca
Disk geometry for /dev/sdc: 0.000-2622488.000 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.031 525333.742 primary ext3
"fdisk -l" zice ca partitia are "537941720+" blocuri (chiar daca discul
e de 0 octeti)
Totusi, mkfs face un filesystem de 3 TB (2.4 TB, 671356342 blocuri de
4k) fara erori. Problem solved :)
