7200 rpm will make some difference in speed but this is an IDE drive so i woudl not really bother wasting the money.

if yu still are inclined here is a drive you can get

120GB Segate 8mb cache 7.2krpm http://www.google.com/product_url?q=http://www.walkietalkiestore.com/index.php%3Fmain_page%3Dproduct_info%26products_id%3D2067&fr=AFq3WtgpFxeG6w-OaDj2lhnPY-hfgD7BWOrHYBeGjAmB_fKNuMS4B-rk2AypX_cR8OHT48A0pRoqFHpCBRHs1kcGJuFD_xqD03F2s1O8vJIF3ZNDpu2m9KrZKcDuAf-hXIOOdOd9HVWnI6v38Rz-ny8bnjtFwA2Qzupmy-QzNtxgAAAAAAAAAAA&ei=iAAITJGvGofslAfjj9mrCQ&sig2=-nWQXI26TC5sUtDBxIiqWg&gl=us&hl=en&sa=title&ved=0CAcQgwgwADgA

pretty much any 7.2K IDE 2.5" hard drive will work but i recommend Seagate followed by Western Digital

I have a 4 channel Sunluxy H.264 Network DVR, I have fitted a 300gb HDD but although the system is working and I get the 4 cameras on screen the message I keep getting on boot up is HDD not found


Guys this one stumped me for some time, here is my solution that worked like a dream

1. plug the hard drive you are using into a pc and check the hard drive is recognise and works.
2. Delete all partitions
3. ensure it has a 8 bit cache buffer!! This is the most important one. That means the system only supports older hard drives. I got 2 second hand ones from the local pc store for $50. See the list of hard drives that are know to work below.

MANUFACTURER MODEL CAPACITY ROTATION
ST3320613AS 320GB 7200 rpm
ST33500320AS 500GB 7200 rpm
ST3750330AS 750GB 7200 rpm
Seagate

WD5000AACS 500GB 7200 rpm
WD6400AAKS 640GB 7200 rpm
WD7500AAKS 750GB 7200 rpm
WD10EADS 1TB 7200 rpm
WD15EADS 1.5TB 7200 rpm
WD
WD20EADS 2TB 7200 rpm
Maxtor STM3500320AS 500GB 7200 rpm

HITACHI HDT725032VLA360 320GB 7200 rpm
HDS721010KLA330 1000GB 7200 rpm

FYI for some reason the person I bought this off online "Ebay" had no idea how to support and I could not get support from their web site as they email they give just bounces back.

Cheers.

New hard drive choices


Hello, Bob!

Seeing as I am a 6 year veteran of Dell Tech Support, I should be able to help you out, no problem.

One thing that I would like to let you know is this: according to Dell Support Policy, you ARE allowed to put a non-Dell-branded hard drive in your computer. However, if Dell Support deams that this non-Dell hdd has caused another Dell component to fail, they will not replace the defective product. BUT, since it is HIGHLY unlikely that a non-Dell hdd would actually cause any other failure, feel free to purchase a non-Dell hdd. (I often times suggested that customers take this route because unless you're purchasing a refurbished Dell product, you're only paying for the Dell name.)

Anywho...

There really are no limitations to what size hdd you can install in your computer. Of course, a larger hdd will take more time to process information (Basically, there's more surface area to scan when your computer is searching for a specific piece of information.). Your main thing will be determining if you have an IDE hdd or a SATA hdd.

The Dell Tech website CAN be your friend (support.dell.com). From there, you can view original configuration and even available upgrades simply by entering your service tag (Usually found toward the back of your computer, on a black sticker with white text. It should list your service tag, an alpha-numeric value, and express service code, an all-numeric value).

If I were in your position, I would most likely not go over a 160g or 200g hard drive... simply to keep decent performance.

Hope I helped!

Replacing the hard drive on a imac G5 first generation



  • speed matters, too, and the quickest way to get a handle on speed is by asking how fast the drive spins. After all, a 7200 rpm drive has to move data faster than a 5400 rpm drive - or does it?
It's Not That Simple If you've been following the story over on Macworld about different benchmark performance between the 2.0 GHz white MacBook and the 2.0 GHz black one, you might be scratching your head. Except for the hard drive, the two 'Books were configured identically, yet some Speedmark results were quite different.
The MacBooks, like most computers made today, can ship with drives from any of a number of vendors, and Apple has made it easy to swap the hard drive in the MacBook. By slipping a 7200 rpm drive into the black MacBook, it came very close to matching the 5400 rpm drive in the white MacBook.
What's up with that?
My first thought was that perhaps one of the drives had a bigger cache than the other one. I've seen a big difference between 7200 rpm drives with 2 MB and 8 MB caches with my eMacs.
But as I read further, I saw that both drives had 8 MB caches, yet the 5400 rpm Seagate was edging out the 7200 rpm Fujitsu in several tests.
Digging Deeper In the world of notebook computers, 4200 rpm drives used to be the norm, and the first 5400 rpm drives provided a huge speed boost (they spin 28.5% faster). Jumping to 7200 rpm spun drives 1/3 faster than that, but that's not the whole story.
Another way to make drives more responsive is to add a buffer. In the ancient days of personal computing, drives simply read their data and dumped it over a bus to the computer as fast as they read it. Old timers may recall setting the interleave for drives used with the Mac Plus, SE, and II - and wonder why we no longer do that.
Setting interleave slowed down data transfer to a speed these old computers could handle, and then someone came up with the clever idea of building a data buffer (or cache) into the hard drive. Now the drive could read the data at full speed, store it in cache memory, and feed it to the computer at the top speed it could receive data.
And that's why one of my favorite Mac SE speedups is putting in an hard drive with a buffer to replace the ancient bufferless drives Apple used back in 1987.
And the bigger the buffer, the more data in the cache, the more efficient the process.
On top of this, there are different schemes for storing data in the buffer. A drive may look ahead a few sectors, or it may buffer the directory, or it may buffer writes, all of which can make things more efficient.
Physics That's drive electronics, and every brand has their own way of doing things. So you can see why a Seagate, Hitachi, or Fujitsu mechanism might offer different performance despite having identical spin rates and buffer sizes.
But there's a third factor beyond RPM and cache size - data density. Looking at the manufacturer's specs for 5400 and 7200 rpm 2.5" Seagate Momentus and Hitachi Travelstar drives, you'll see that the transfer rate of the 7200 rpm drives is less than 1/3 faster than the 5400 rpm drives - just 9% faster for the Seagate, and a more impressive 28% faster for the Hitachi.
The big breakthrough over the past year or so is perpendicular recording, which can easily store 50% more data per track. Just how much data is there per track? That's hard to know, in part because the manufacturers don't promote the number and also because the amount of data stored per track varies between the inner and outer tracks of a drive platter.
Still, if Drive A spins at 5400 rpm and stores 40% more data per track then 7200 rpm Drive B, it will be able to read more date per second. That might help explain how a 5400 rpm drive can sometimes outperform a 7200 rpm one.
Conclusions Tech Report has an extensive article comparing these four drives. It looks at peak transfer rate, how well each drive handles multiple data streams, and typical read and write speeds. And just as Macworld discovered with the MacBook and both brands of drives, Tech Report says, "At times, those performance differences were surprising, as we certainly didn't expect to see Seagate's Momentus 5400.2 beating Hitachi's Travelstar 7K100 in so many tests."
Various drive parameters can be tweaked, optimizing a drive for use by a single user or in a server, even optimizing for the way an operating system works and how many data streams it may work with at any given time.
In the end, there's more to picking a hard drive than capacity, rotation speed, and buffer size. Seagate, Toshiba, Hitachi, and Fujitsu each have their own buffering algorithms and optimization schemes, so you'll want to look for benchmark results using the hardware and operating system you'll be using. (OS X on Intel Macs may produce very different results than OS X on a G4 or G5 system.)
Price is the final factor (after all, Low End Mac is primarily about value). If ultimate performance isn't crucial and the 5400 rpm drive is a lot less costly, it may well be a better choice for you. But in the end you have to come up with your own value equation - how important is capacity vs. performance vs. price? bullet.gif
