Replace failed drive in pool

I am not very savvy with Solaris but am responsible for a server running Solaris 10 that has a failed hard drive in a mirrored pool. I ordered a new drive and attempted to install but received the error "device too small" when using zpool replace. The drive is the same Seagate model number as the old one and has the same nominal capacity of 300GB. Here's what prtvtoc says about the disks. Note that c1t0d0s2 is the new drive.

Code:

# prtvtoc /dev/dsk/c1t0d0s2
  * /dev/dsk/c1t0d0s2 partition map
  *
  * Dimensions:
  *     512 bytes/sector
  *    4470 sectors/track
  *       2 tracks/cylinder
  *    8940 sectors/cylinder
  *   65535 cylinders
  *   65533 accessible cylinders
  *
  * Flags:
  *   1: unmountable
  *  10: read-only
  *
  *                          First     Sector    Last
  * Partition  Tag  Flags    Sector     Count    Sector  Mount Directory
         0      2    00          0 585865020 585865019
         2      5    01          0 585865020 585865019
  # prtvtoc /dev/dsk/c1t1d0s2
  * /dev/dsk/c1t1d0s2 partition map
  *
  * Dimensions:
  *     512 bytes/sector
  *     625 sectors/track
  *      20 tracks/cylinder
  *   12500 sectors/cylinder
  *   46875 cylinders
  *   46873 accessible cylinders
  *
  * Flags:
  *   1: unmountable
  *  10: read-only
  *
  *                          First     Sector    Last
  * Partition  Tag  Flags    Sector     Count    Sector  Mount Directory
         0      2    00          0 585912500 585912499
         2      5    00          0 585912500 585912499

From what I read, I understand that a mirrored pool cannot shrink. So since I'm not really familiar with all of this, I ask why cant I just create a new pool? Can this be done without loosing the data on c1t1d0s2?
