Backup the backup USB drive?
Hey all!!
2 questions... First question: I was considering getting a 500gig external USB disk: (http://reviews-zdnet.com.com/LaCie_E...?tag=pdtl-list) Of course, if anyone can suggest something better, please tell. Now I want to use that drive for just media (videos, music, pics etc). The thing is, I'm worried about what happens if one day the new external drive dies. In order to prevent that, I was wondering how difficult it would be if I purchased say 2 of them, and wanted to "sync" them every once in a while. I'd use the first disk regularly for new mp3s etc, then every month say "sync" the two drives together. Can this be done reasonably easily? What software would people recommend? Second Question: I have at the moment 2 Ultra ATA drives (80gig, 120gig) and a UW SCSI drive (9gig). I want to upgrade my system to UATA HARDWARE (save the CPU) RAID 1 (disk mirroring rite?). and dump the SCSI disk/controller. In order to do this, I wanted to know: 1. While keeping my 200Gig of usable capacity, and not having to reinstall everything or throw any hard disks away, what's the best way to set something up? Was thinking of getting a 220gig drive or something and partitioning it to 80 and 120gigs, but I think with hardware RAID that might not work. What are my options here, and what controller would people recommend? Is a caching controller worth the money? Phew... thanks for reading so far, I hope I've been clear!! Look forward to any responses ^_^ My email address is wrong, so just reply to the group. Thanks!! Raj |

Now I want to use that drive for just media (videos, music, pics etc). The Warranty is only one Year,so i would say,dont buy it! Two external USB/Firewire-Enclosures with each a 400GB Hitachi/Seagate Disk would be better/cheaper.Also this would work with at least XP SP1. With 2 Lacie BigDisks,there are 4 Drives (2 Drives in each BigDisk).So the Failure Rate is twice compared to 2 independent Single Drives. The thing is, I'm worried about what happens if one day the new external drive dies.

I'd use the first disk regularly for new mp3s etc, then every month say "sync" the two drives together. Can this be done reasonably easily? What software would people recommend? Really easy and free with xxcopy from www.xxcopy.com A single "xxcopy d:\ e:\ /clone" will write the contents of the first Disk to the second.If you want to sync the second to the first Drive,just revert the Drive Letters. Second Question: I have at the moment 2 Ultra ATA drives (80gig, 120gig) and a UW SCSI drive (9gig).

What are my options here, and what controller would people recommend? Raid 1 or 5 onto different Disk-Sizes will give you only the Capacity of the smallest Disk! I am currently looking at JBOD-Controllers.They will treat each Disk independently.They dont offer any Raid at this Moment to you,but you could keep your ATA-Disks. Try this:Ghost your 80GB and your 120GB Drive onto the new 200GB Disk.Then put them onto the JBOD-Controller and look,what will happen. But at the Moment,i dont know,if they will write some special "Code" onto the Disks,so that the Data on there will be lost.I think no,but i dont know it yet. Is a caching controller worth the money? Yes!An older Mylex SCSI Raid Adapter wrote around 7MB/sec,with some Cache put on it,it wrote about 11-12MB/sec.Its worth and Memory are cheap now. Phew... thanks for reading so far, I hope I've been clear!! Look forward to any responses ^_^ My email address is wrong, so just reply to the group. Thanks!! Raj I would only reply to the Group.For personal Support via Mail i charge 150$/hour.Just a joke :-)) |
