Is anyone using LVD hard drives for PT on Macs?
If so, which ones and with what controllers? Thx, steveV |

Re: LVD hard drives ??
I bought a couple of seagate 18 gig lvd's because I found them cheap. I didn't do any research, just bought them because they claimed to have faster seek times, and I thought that would be a good thing. It was a big mistake. Benchmark tests against the non LVD version of the same drive show that the LVD version only handle ~100 write operations per second, while the non LVD version was well into the thousands of operations per second.
I am currently licking my wounds, and using the LVD drives as bounce space. Since the read speeds are comparable to the non LVD drives, I could also move sessions there once they are recorded and I am only mixing. -Michael Toy |

Re: LVD hard drives ??
Michael,
It sounds like your drives' mode pages might not be configured properly. What drives are they? (Make, model, firmware rev) Do you have a mode page editor, such as FWB Configure or Anubis Power Control? It sounds to me like the write cache might not be set on your new drives. ------------------ --Steve Rosenthal, Digidesign ETS

Adaptec and Seagate have materials on their websites that suggest that with this mysterious 'LVD controller' that these drives are much faster than SCSI2 or -3. In transfer rates anyway... Anybody? thanks Michael & Steve, steveV |

I forgot I posted this question here, so I didn't get around to replying until just now. Where do I get FWB COnfigure, is it a seperate app that I can buy?

I'm using a pair of Seagate ST39102LWs with a pair of the older Cheetahs ST19101Ws. The LWs are jumpered for single-ended operation, and they smoke! There's no reason to buy anything other than an LVD drive, since they can easily be configured for standard wide or narrow busses. BTW, I have them connected to an Adaptec 3940.
MToy, there must be something wrong in your setup, because the LVD drives are much faster than the standard wide drives, even on a standard wide bus. |

I also have Cheetah 39102LW and 19101W drives and I find that the LWs really are the mutts nuts....I can get a full 64 tracks out of one of those puppies in a Glyph, Rorke, Data Express or Tyrestor hot-swap rack straight out of the box.............where have I gone right?! Cheers all Ade |

FWB Configure is the answer. When the write cache is turned on, everything goes like the wind! Thanks.

Hmmm, cool.
Now, I have a late version of FWB HD Toolkit PE... Is the Configure for LVD in there? Or is it a stand-alone, a download, wha...? Thanks! steveV |
