Today I came across one of theses drives.
It looks like its a good drive. How can I test or make use of it?

None of the machines I own have SCSI interface.

Get a SCSI Card . It doesnt say if the drive is 50 pin, or 68 pin..

Ultra320 is 68 pin. Thanks for the reply.
I was so happy to find this HD my brain did not think to google for scsi adapters.

Man those things aint cheap. I did not pay as much for the drive as I may have to pay for the adapter.

You can always give me the drive I have an adapter for it

If your not running RAID , the cards are alot cheaper, just make sure its a NON-RAID card

The Adaptec 2940W should run ya between $20 to $40 bucks

How do I tell if it is designed for raid only?
http://www.seagate.com/cda/products/...81,650,00.html

This is the best link for info that I could find and from all of that info I don't see where it says
it's specificly for a raid config or a standard HD.

I did not know some HD were made for raid pairs only.

As far as I know there is no RAID ONLY drive made, the raid drives "sink up " better than reg. drives and have some other benifits , I was talking about the SCSI adaptor you need to use the drive being a raid capable or non raid type of card .

And to answer your question , YES you can use that drive by itself , it does not need to be raided

Example of a RAID drive and non RAID

yeah =) the hard drives that are made for raid will run by them selfs... but it is not recommend as they die quicker... i made that mistake with some wd2500sd sata drives...

Oh now I see you were talking about the SCSI adapter card being raid compatable.
This is the only one I was able to get so its gona be a single drive without a raid brother.

Yeah , then you just need a good SCSI card , I like Adaptec & 3M Ware ( 3M 's are Xpencive)

Actually, the question should be "Is it 68-pin or 80-pin SCA?" They don't make 50-pin SCSI hard drives anymore. They do, however, make them with 80-pin hot-swap plugs, which you can spot (besides counting pins) because the drive has no Molex power connector. In that case, you'll need an 80-pin to 68-pin adapter, they run about $15. Don't forget you'll need a cable with a terminator to hook it up and test it, along with the card.

Thanks to all for the helpful information.

anyone else notice that in this thread the title box of each post after my original post reads

Re: Whats with the new title editions here?...

I noticed that too, must be along with all the color changes

seems like its just making every post say re: and the original title

Ok now for more questions on SCSI. Where does it get power from?
There is no molex or SATA type connections on the HD.
Does it get power directly from the SCSI adapter card?

Thanks again for all the help.

Well Assuming the servers use adapters, then thats where they get the power from. My other theory is that they get it from the card itself, Ive looked at the specs on the drive and it only consumes .5A

look at my link for pict's and info.

looking for scsi raid cards and adapters.

SCA2 80pin - SCSI 68pin LVD Adapter


Make sure the adapter is Certified for SE / LVD speeds up to Ultra320

RAID
COMPAQ PROLIANT 5300 RAID SCSI CONTROLLER W/64MEG


NON-RAID
Adaptec SCSI Card 29160


SCA2 80pin - SCSI 68pin LVD Adapter


RED = POWER
BLUE = 68 PIN SCSI CONN.
GREEN = JUMPERS FOR ADAPTER

That means it's an 80-pin hot-swap drive. You'll need an adapter like Cuban's got pics of, they're about $15. It uses standard molex power, but it goes through the 80-pin adapter.

(EDIT)
In a server hot-swap rack, it's basically a backplane board that has several 80-pin plugs on it. The backplane sets the drive's SCSI ID number and provides power to each drive, so that if you have to swap one, you don't have to reset anything, just pop it in and go. You don't even have to shut the machine down. The single-drive adapters (I have a couple) do the same thing: provide power and set the SCSI ID#.

Yea but whats the difference between LVD and SE Converters?

iehttp://www.hypermicro.com/product.asp?pf_id=ADHM337 and
http://www.hypermicro.com/product.asp?pf_id=ADHM868

Ultra2 SCSI Low Voltage Differential (LVD) drives, benefits, compatibility

SE (single-ended) SCSI with SCSI converter

LVD/MSE to SE Converter

Convert Between LVD/MSE and Single-Ended
Extend Bus Length
Isolate Segments of a SCSI Bus
Targets and initiators may be located on both the A and B sides of the Expander
The Series 80 models are backward compatible with older versions of SCSI
Does not consume a SCSI ID

Ultra2 SCSI Low Voltage Differential (LVD) Drives

Seagate’s high-performance Cheetah and Barracuda drives (drive models with a suffix of LC or LW - click here for list) are ushering in the future by utilizing the super-fast LVD Ultra2 SCSI parallel interface capabilities. Users of video, database servers, RAIDs, workstations and high-end desktop applications benefit from the greater I/O bandwidth, device connectivity, data reliability, and cable lengths offered by LVD. With the capability to multi-mode, Seagate LVD drives are backward compatible with single-ended Narrow and Wide SCSI devices (not High Voltage Differential) and provide cost savings, rapid bus rates and increased reliability.

Hope that helps alot of good info in that link.
