Re: 3 TB disk troubles
I could be completely off mark here, but does that external drive have eSata too ? Your problem resembles a lot something I struggled with a while ago. I'd bought an external hd case + a 3TB drive for my girlfriend , the external hd case supported eSATA and usb . I had a lot of problems when connecting that 3TB drive to my laptop via usb (I didn't have eSATA), the drive showed up as only 2TB . It turned out that the external drive case required to be connected via eSATA for +2TB drives, the manual said so, I had only forgotten about that . Via eSATA the drive was recognized as 3TB, I think the 'problem' was OS agnostic, since the same happened on my girlfriends mac. regards Joar Jegleim On 14 February 2013 12:16, Scott Bennett wrote: > I recently bought a 3 TB external hard drive.

3 TB disk troubles
I recently bought a 3 TB external hard drive. I attached it to the Firewire (400) bus and waited for my 8.2-STABLE i386 system to recognize it. After a small flurry of Firewire protocol messages, the kernel eventually said, Feb 12 23:35:42 hellas kernel: da2 at sbp0 bus 0 scbus0 target 1 lun 0 Feb 12 23:35:42 hellas kernel: da2: Fixed Direct Access SCSI-0 device Feb 12 23:35:42 hellas kernel: da2: 50.000MB/s transfers Feb 12 23:35:42 hellas kernel: da2: 2861588MB (5860533167 512 byte sectors: 255H 63S/T 364801C) So far, so good, I thought. Next I tried to use gpart(8) to set up a partition table. However, gpart, gpte (from sysutils/gpte), diskinfo(8), et al. only see the device as a 2 TB drive. hellas# diskinfo -v /dev/da2 /dev/da2 512 # sectorsize 2199023253504 # mediasize in bytes (2T) 4294967292 # mediasize in sectors 0 # stripesize 0 # stripeoffset 267349 # Cylinders according to firmware. 255 # Heads according to firmware. 63 # Sectors according to firmware. # Disk ident. hellas# I have searched the archives of this list and several others, but haven't found anything helpful. This disk is *not* intended as a boot disk, just data storage. Is there any hope of using its full capacity? Or have I effectively bought an overpriced 2 TB drive?
