Unhappy

I have a problem with a HD.
It's listed as a ST312002 3AS SCSI Disk Device on my hardware list. And as It's my drive F, a 120GB HD. The problem is that after a few days of hard work it happened that the disk got duplicated... now i have my drive F and a new drive G with the same stuff inside...
Now my computer runs a system check every time it starts and I'm loosing data from drive F every now and then. The drive apears as healthy in the Computer Management where by the way drive G does not exist...
Some programs, mostly games do not run from that drive anymore cause they say the drive is cycling or something like that!!! did my HD went for a bike ride!?!

What can I do??? please help...
I ran nortons defragmentation and I lost almost 60% of data. Folders just gone! Am I doing something stupid or just plain ignorant? is this normal, I don't know?

let me stress: HELP!!!

I suggest

you run a full virus scan and spy / ad ware scan


Norton anti virus 2004 and Spybot search & destroy will do the trick i think.

back up that data if u can, if you didnt already, and format that drive if a virus check comes up empty

I already ran the virus check and it came up empty. I guess there's only one more thing to do.... format F:

Enter Haven Fault tolerance for Post production work

You bring up a lot of good information about drives going more the way of IT companies. A lot of the testing utilties you mention test directly from the hatrd drives and not under windows.

In any event, on a lsightly higher scale, it is nice to have a drive systems designed specifically for post production and more importantly for HD post production.

1080i still plays back even with a drive missing.

well that certainly is a trick RAID6 PCI-X SCSI monster
and yes I covet it, however its just a tad out of my price range currently

Ive made do the its "predecessor"....from half a decade back that is
a DotHill SANnet 3200\2200 @ 1TB
Dual Channel, Dual RAID, N+1 Power, and about $12,400 less
(actually I have 2 more 3200s as well each ran me about $500 often populated)

definately not the same performance but at this time I dont really need that level either
but others certainly may

about RAID

can anyone tell me
does RAID 0 or RAID 5 makes render faster??

it doesn´t make rendering faster
it may make saving the image / file faster

so yes, your render may be finished in shorter time
depending on the files it produces

Well, RAID 5 will not help at all in write speeds.

RAID 0 will but you give up redundancy--and in that if one of the drives or the stripe or the RAID card fails you lose everything.

Rendering is not affected by your drives.

Loading textures or scenes would be as well as saving them. Other than this, you gain nothing from RAID in this sort of configuration.

The article mentioned one of the main problems of harddrive cable is the length of it. Recently, I've been having problems accessing files from one of my harddrives that utilizes the ribbon (as opposed to SATA line), and I think it may have to do with my ribbon giving out. So now I'm trying to buy the shortest UDMA cable I can find. Can anyone find one shorter than 18" that still supplies for 2 harddrives?

You should be fine with 18" cables. The IDE spec doesn't allow for lengths greater than 18" because the integrity of the signal degrades drastically after that point.

Yes, shorter is always better but 18" cables should be fine.

Well, it turned out to be a windows problem (figures), that I fixed using system restore....not a ribbon problem. It's odd though, most stores sell 24" cables, even though the 'IDE standards' call for cables 18" and shorter.
