Why would it change the geometry? I have used this tool to change the settings on all my disks and it did=20 not in any way cause a problem booting later. My disks are WDC WD10EADS-00L5B1/01.01A01 (1Tb "green" disks) AFAIK it just tunes EEPROM settings, it doesn't reflash the firmware. That said I have heard reports of it bricking a drive so I would test it=20 on one drive first (not that I did, I heard the bricking reports=20 later..) =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart4814856.fuMKQumRO5 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iD8DBQBLcKxo5ZPcIHs/zowRAu6+AJ0YtVNOAg8LWLp2dgkv3x+NvnlNrACgmTot 0eibJt0w5WCP0RtCGnX0tMY= =oSmG -----END PGP SIGNATURE----- --nextPart4814856.fuMKQumRO5--
