The HDD is not identified correctly by the mainboard/Bios with 3TB. This BIOS isn't important for Linux (in that case). It just has to boot Linux, after that BIOS is out of the picture (for storage). > is confirmed by the hardware vendor of my mainboard "Gigabyte P35-DS4", > means the limit is 2.2TB P35 sounds too old for me. AFAIR older Intel-Hardware has a problem with the 2TiB Barrier. For the 2TiB-Barrier you need a recent system, something younger than about 2-3 years. Most hardware older can't cope with discs bigger than 2^32 sectors. > > How can I recover the data? > Should I simply create a new partition table either with gdisk or parted? > Can I make a low-level copy using dd starting from sector 2048 until the end > to another HDD WD30EZRX (that I have available) and then mount that > partition? > Or are there any other options? Just plug it into a more recent system, it should "just work". -- Matthias _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
