Skiny ATA and RTCP

WE have a big network with multiple ATA's. I've many complains concerning the quality of the VOICE. Is there any method to collect the RTCP info for each call?
Note: I'm looking both for ATA<->ATA as well as ATA<-> H.323 GWs cases.

Hi,
You should check delay, jitter and packet loss etc.

IMac G5 (pre-iSight) Hard Drive Removal: ATA and SATA advice please!

I need to purchase a hard drive enclosure for the hard drive of my old 1st gen iMac. According to this article: http://www.welovemacs.com/ihaimg5whtyo.html - my iMac has an ATA drive, and is the only with that type. So my question is, before buying an enclosure, does it have to be specified for ATA hard drives only? I read some positive reviews about the miniStack v3 (http://www.newertech.com/products/ministackv3.php) and was considering it a good investment, but now I'm not sure if my stone age hard drive will actually run on it. I poked around their web site, but its a bit cluttered and couldn't find an answer, so I figured I'd turn to you guys; the experts!
Thanks for any help in advance! You guys are great!

Thanks for the speedy response. I'm looking through the website right now. But basically pretty much any recent enclosure holds both ATA and SATA hard drives? I got a little more information on my hard drive to clarify: Barracuda 7200.7 with 80GB. With that said, I'm probably just going to go ahead and order an enclosure and not worry too much about compatibility; however, I would feel better if someone could tell me if the miniStack v3 (link is above in the original post, says it can hold a max of 1 terabyte) is a definite "yes or no" given what I'm dealing with (and if anyone has had any personal experience with that enclosure, I would be glad to hear any general comments about it as well!) Thanks again

URGENT!!! Can ATA and SCSI coexist?

hello fellas!
my case is similar of the post "Can SCSI and ATA coexist?', but with some differences:
I own a G4 Dual 500–MHz PowerPC G4, 40Gb ATA + 80GB ATA. (http://support.apple.com/specs/powermac/PowerMac_G4_GigabitEthernet.html)
now I've installed a PCI SCSI card to connect tree more SCSI HDs: two barracuda 18Gb and one quantum 36Gb)
my G4 only reads SCSI drives when I disconnect ATA tape from motherbard...
when I plug ATA to motherboard again, neither SCSI mount on desktop, nor system profile shows it as a device, even when I start Hard Drive Update 1.app...
I've read all manuals from apple, jumped all SCSI HDs, but for some reason, it doesn't work at all!
so, the question, again, is Can ATA and SCSI coexist?
does anyone knows how to config it??
thanks in advance!

answering:
- as my primary language is portuguese, i didn't understand when you said 'booting off the OS X disk'. do you mean eject it in the disk utility?
- I have so many drives because e sold another G4 that used those drives atached with the pci card and I simply want to use it, because I'm short on cash... those drives are installed with OS 9.2 (the ATA ones are running OS 10.4.8)
when you said one ATA and 2 SCSI, you mean that if I simply disconnect the slave ATA and one of the SCSI it may works?
thanks again!

Is my HDD an ATA and is on ATA bus 0 ???

My powerbook is 1,67 GHZ and 80 Go and won't boot , the optical drive is broken , so i use target disk mode to reinstall it . But it shut down when i press the "T" button to enter TDM. And if i don't press "T"
According to Apple ,I must be sure that my hard driver is an ata and on ATA bus 0 because "it's normal for a computer to shut down while entering in Target Mode if it hasn't detect any ATA hard drive on a ATA Bus 0
What is ATA Bus 0, the only thing i know is that my Hard is an ATA/IDE
What to do for solve this problem ???

There is another reason you may not be able to enter target disk mode, which is if you have a firmware password on your system. See this Apple note: http://support.apple.com/kb/ht1352
My 1.67Ghz Powerbook has the internal hard drive as defined By Apple, ie, there's no option to change the ATA bus designation, and it can enter target disk mode.

VoIP packet mis-insertion between ATA and E&M card

Hi,
I have run some subjective audio tests between an ATA and and E&M card in a 3745 router and found problems end to end. ATA to ATA and E&M to E&M perform perfectly. We have narrowed the problem down in a lab by having a single ethernet crossover between the ATA and 3745. Still we see problems. When we look at call parameters we see late and early packets plus a lot of Predicted seconds. We expect to see some but there are a lot on the ATA to E&M setup which we think are causing the subjective tests to fail. This is not unit related as we have tried many units and upgraded to latest H323 ATA firmware and latest IP plus on the 3745. I am sure QOS can't come into this as this is an isolated setup with 100M/full duplex etherenet between the two devices. The predicted seconds parameter starts to run up after about 60-90 seconds of call time and after a few minutes maybe about 500mS in total. This does not happen to the same extent with the ATA to ATA or E&M to E&M, maybe 50mS after 30minutes! Is this buffer related or a Cisco 'feature'!? Any help appreciated.
Regards,

I don't see 'predictive seconds' in the output but here is where I do see an issue:
RxOutOfSeq=9<--main issue,packets out of sequence
RxLatePak=0
RxEarlyPak=1
PlayDelayCurrent=55
PlayDelayMin=55
PlayDelayMax=65
PlayDelayClockOffset=-293476173
PlayDelayJitter=0
PlayErrPredictive=180<--causes this
PlayErrInterpolative=0
PlayErrSilence=0
PlayErrBufferOverFlow=20
PlayErrRetroactive=0
PlayErrTalkspurt=0
So do a sniff at the ATA and a sniff at the router, are the RTP packets in sequence when they leave the ATA and out of sequence when they arrive at the router? If so, network issue. If they are out of sequence leaving the ATA, please save the capture and open a case with TAC.

Difference between ULTRA ATA and SERIAL ATA

Hello,
What is the difference between ULTRA ATA and SERIAL ATA ?? Is the connector different for each type ?? Thanks in advance.
Robert Lespérance

Was wondering why you are considering a ATA drive? The iMac G5 als has a serial ata drive already.
If you are considering an external drive, then you have a problem. The most important thing there is that you get a drive with firewire interface because I think they are the fastest, but USB is an ok choice. If there is an external firewire drive that also uses a serial ATA drive inside of it, then that would be an excellent choice for speed. USB or Firewire are standards for connecting a peripherial to you Mac. An external drive will probably have a very common, read Mactor, WD, Seagate, ATA drive in it. The external drive case has a interface inside of it which allows USB or Firewire to speak with the ATA drive, any flavor. Some people just purchase a powered external 3 1/2 case and install the hd they like the best, that is the nice thing about standards.
I think serial ATA will pretty much spell the end of all of the older ATA drives. The serial drives are actually very competitive in price now and faster.
Suggest you go to Western Digital, Maxtor, and/or Seagate's web sites to learn what drives they offer.

Neo4 Dual Drive ATA and IDE boot from ATA?

I just set up a Neo4 board using two drives. A seagate 120Gg ATA drive and a Maxtor 200Gb IDE drive. I would like to use the ATA drive as the boot drive but I can only seem to startup from the IDE drive. Is there a trick to get this working?

Quote from: Richard on 28-September-05, 01:07:15
ATA and IDE are the same thing.
Huh. Well. Okay, perhaps I'm not posing the question properly. The seagate drive is plugged into the SATA1 position, while the Maxtor is plugged into IDE1. They use different cables and connectors which is where my confusion started I guess. In the BIOS when I select the seagate drive to boot from it will not boot. But it does off the Maxtor. I have no reason to believe the drive is bad but hwo knows. I guess I just want to make sure I'm not missing some setting to properly boot from the SATA1 position when both drives are attached.

CUCM mulitiple paging via ATA and third party paging system

We have several campuses in our school district that use an ATA connected to a third party paging system. A couple of the Schools are merging...and they wanted to know if we could in some way "link" the two paging systems so that they only have to call one extension when they page. We are currently using CUCM v 8.6.1
Thanks,
Greg

Yeah, that won't work, plenty of people had already tried that to simulate a paging system, you only get the connection to the device that answers the call.
The only possible way I can think of, assuming they're in the same physical area, is to actually fork the cable from the ATA to the paging system.
If not, they'll have to live with two DNs for paging.

We have 2 XServe Raid 14x750GB Ultra ATA and rack cabinet, xserve and fiber to donate to anyone who can pick it up (chicago)

Our Studio is holding onto a full rack cabinet, 2 XSERVE Raid 14x750GB Ultra ATA units, Exabyte Tape Back up system (with 750GB tapes) and Xserve all purchased directly from Apple and only used as our video backup system. It's a bit dusty from being out of use, but in excellent condition.
Studio is in Chicago. If you can come and get it, it's yours.
We also have some hot spare parts that came with the purchase.

I'd love to but need whoever wants it to come and pick up (Third Floor Studio ) The Rack, can of course be emptied, but those muther's are heavy Not sure it would be worth you paying moving guys to deal with?

RTP and RTCP in JMF

I need to test VoIP application in a wireless network. I have a program that reads a sound file and creates a RTP session to send it to other computer. In order to measure the application performace I need to take the following metrics during the RTP session:
- Packet loses.
- End to end delay
- Jitter
The questions are: how does JMF implementation of RTCP can help with all this metrics?? Does someone know some example code?

ATA and Ultra ATA

Is there aa difference between the ATA hardrive in the iBook and the Ultra ATA in the PowerBooks? I want to buy a new harddrive, but everywhere I go I only find ATA drives. What is the difference if any?

Don't worry about the terms. You just need any 2.5" ATA drive but not a Serial ATA (SATA) drive (these are for the very latest laptops). A rough history goes something like this:
ATA = 8Mbps?
ATA2 = 16.6Mbps
Ultra ATA/ATA33/Ultra DMA = 33.3Mbps
ATA66/UltraDMA 66 = 66Mbps
ATA100 = 100Mbps
ATA133 = 133Mbps
SATA = 150Mbps
SATA2 =300Mbps
If I've made a mistake I'd be grateful if one corrects me!
If you buy a modern ATA133 device it will be compatible any ATA device (not SATA). It will slow automatically. I think the original iBooks were ATA33 and the Ti Powerbooks ATA100, but I can't find much info about this from Apple.

Using S-ATA and Radeon 9800SE?

Hi!
Have read a number of posts in this forum about the incompability between the Intel Serial-ATA controller and the Radeon series graphics card and was just wondering if there is someone out there who has come up with any real solution to the problem, other than running a Parallell-ATA disk instead? Had serious problems when trying to run 3D apps and games on my computer with an Maxtor 120GB S-ATA disk, and a Club 3D 9800SE graphics card, (instant system lockups with hard reset as the only solution), and tried all the usual stuff to get rid of the problem, (swithed PSU, upgraded the BIOS, upgraded all drivers etc.), w.o. any luck. (When I tried to install a GeForce 440MX card instead, all worket just fine). But when I switched to a P-ATA disk and installed the system on this disk instead, all problems went away! Is it MSI I should blame for installing a crappy S-ATA controller, or is it ATI who are having problems making a desent driver for their GPU? Regardless what, I would really apreciate if someone else with the same problem, and a solution, could make a post on this forum!

I have had no problems with the above mentioned combo..... EXCEPT, when using ICH5R. With the Promise it's worked well on most all machines except a Neo2-LS which required me to set the PCI LATENCY to 64 before it would work. On the "few" (and I stress "few" as I do not claim to be any expert) ICH5R setups I've used, I had to set the latency as high as 128.
Apparently since by default ATI cards want to use 255 clocks LATENCY TIMER, the SATA was only asking for 32 CLOCKS. The Radeon was hogging up all the bus bandwidth. Setting it to 128 cured the problem. Either that or the AGP wasn't able to hold onto the bus long enough to properly finish it's data transactions. Either way...
This however contradicts the notion that I've been told "PCI LATENCY TIMER CAN ONLY BE CHANGED IN WINDOWS 2K/XP using a utility like Powerstrip." However I'm thinking that this worked for me because by choosing a medium between 32 and 255 allowed the cards to balance out in XP, as 32 clocks allowed the SATA to take too much control over the PCI Bus, or the ATI to give up too much control.

Is ATA and ATA150 the same interface?

Is this hd compatible with a MacBook?
http://www.newegg.com/Product/Product.asp?Item=N82E16822146053

When you boot from the install DVD can you see it under the system profiler or disk utility to initialize it for the Mac? Most HDs come formatted for Windows and while our Mac should still see it, you will want to format it HFS+ for use in your Mac.

Internal DVD disappears including from ATA and Burning in Mac info

I have an open ticket on this issue, my internal DVD appears and disappears. I'm not sure if this is a loose internal connection or a firmware issue. If it is a loose connection, I guess that I will have to send it back to Apple for repair. I understand that disassembly is a pain.
The issue may have to do do with connecting to external Firewire drives. Has anyone ran into something similar? I expect to play with this for a few days until I am more confident as to the real issue and would appreciate any input. Apple support has been great. But, I've done tech support and really want to have the issue nailed down before I send the Mac in for repairs.

The computer is now running correctly and the DVD issue is no longer occurring. My best guess, at this time, is that it was something like the Windows registry "noide" issue. In other words one of the setup scripts was hashed for some reason or another. As I believe these rewrite themselves, the issue was self repairing.
No one else seems to have had the issue, so it was probably specific to my system. Should someone else have this issue, I suggest disconnecting the computer from all connections including power overnight. this seemed to temporarily fix the issue the first two times. The third time was several days ago and it is still working correctly. I will add to this thread if I find anything new

PCI ATA and SATA question.

Anyone know if a Promise ATA PCI card I have on my PC would work on my "Digital Audio" Mac?
If not, can anyone tell me if there is an ATA & SATA (both in one) controller card compatible with this Mac?

Hi, Sergio!
The Promise card from a PC won't work. It has incompatible firmware, designed for PCs. You need a card with Mac firmware. Here are some examples.
