Challenging Situation with IDE1 IDE2 and Optical Drives

I had setup my new build, which is in my sig. To start with, I just hooked up a cd-rom to install software with. After things started to shape up, I decided to hook up my dvd/rw on the same IDE channel as the CD-Rom was on. I inadvertantly had hooked these up to IDE 1 and had decided maybe they should be on IDE2. Well, I had a no boot situation at that point. I then just switched the optical drives cable back to IDE1 and all is well.
My question is, does it matter which IDE channel the CD-Rom and DVD\RW are on, as long as there are no other drives involved.
My Sata HD is on Sata1.
Just don't know if there would be any speed difference in the two choices???
Thanks for any input, advice. The machine seems to be running like turpentined Fox.
Regards; Pop's

Answer 1: No, there shouldn't be a problem if they are connected to IDE1 or IDE 2
Answer 2: There will be no speed difference as both IDE1 and IDE2 provide same speed transfer
However I would hook them to IDE2. Certainly there would be no problem to be on IDE 1. I had this myself but MSI manual says "the first hard drive should always be connected to IDE1". They may as well mean optical drive, but when I had my DVD-RW on the Primary IDE channel, I had problems flashing it - carefully looking at it and I saw NEC reccomends that when flashing drive bios the drive needs to be master on the secondary IDE channel. I did it and I had no problems.
Now your windows had the drivers for your drives installed and it may be looking for them on the original(IDE1) place of installation - and there you go - a problem.
Another version - you may try to reset bios or to allow bios to find the drives on their new position(IDE2). I had this problem also, but when I allowed the bios to find them - no problem afterwards. It's just your bios that remembers that there are drives on IDE1 and all of a sudden there is nothing there. I believe that this is most likely to resolve your problem.
Let me know if the above helps.
BTW I believe you set the jumpers to master and slave on the drives? And you have the correct bios settings like enabling IDE2 etc.

Upgrade of my PB with new hd and optical drive

Hi all
I have just upgraded my HD and optical drive on my powerbook to give it a bit more space and facilities.
This is what I have done.
1/
HD (80GB)>>becomes HD (250GB)
I used the WD2500BEVE to which I clone in an enclosure. Then I swap them.
This procedure worked well, and the PB booted straight away. Although I go a little folder with an apple as a first screen for a second or 2.
2/
I replaced the combo drive with the Panasonic UJ-85J
It seems to work straight out of the box, and I can burn from finder. I am still in the testing process, but so far I have been able to burn cd-R (max 24), and dvd-R(max x4 instead of 8). That is with finder.
This is what the System Profiler gives me.
Model: MATSHITADVD-RAM UJ-85JS
Revision: FWR7
Serial Number:
Detachable Drive: No
Protocol: ATAPI
Unit Number: 1
Socket Type: Internal
Previously with my old drive, it read> Unit Number: 0
Also the serial number is blank for the optical drive.
The company I bought it from, checked it and told me that it was set-up as master (I guess this is from the firmware) as there isn't any jumper. We did check the System Profiler before together, and both drives (HD and optical drive) were reading Unit Number: 0
He didn't know much about Macs so he didn't really know what Unit Number was, but guessed that 0 meant master and 1 slave?
But here are my questions:
Another thing that has changed, is when I play a DVD movie, the image quality is rather poor, kind of pixilated, and when I enter the full screen mode, I now have a vertical black border (about 1.5 inch) on either side of the image. I have tried with VLC and it does the same.
Does any body knows what is happening?
Also is it possible to test the PB with its covers open ( i.e.with KB plate) without killing the PB?
Many thanks

Dam I don't believe it.
I have now played quite a lots of dvds for testing.
They all display in a different manner. Some play full screen with a good quality, some have a few mm to a cm of black line on the right and left side (the image not expending to the full screen capabilities, some have over 1 inch of these same black lines. The video showing the black lines usually shows poor quality images, contrary to the one going full screen that are as good as before. That might be due to the excess of information in a restricted area but I really don't know.
VLC shows exactly the same behaviors.
On DVD player I discovered the zoom-in facility (I can't remember this before), which helps getting rid off the line, but doesn't improve the quality of the image.
All my DVDs have been purchased in reputable shops, and to my memories, all these movies were playing in full screen mode before with a good quality.
As I said earlier, I have also played these with an external drive, but this didn't change a thing.
There is an other thing that I remember when I first tested the new HD in the enclosure. I did a fresh install of tiger first to see if the enclosure will cope with booting. I discover in the fresh install OSX that I had files in the trash, that were not even on my internal HD. I remember reading about HD with malicious viruses installed straight out of the factory. Could that be it?
Although I have read also about people experiencing similar phenomenon in iTune, when one day all worked fine and the next day, they ended up with the black lines that seem to be very similar to mine.
Please help, as I have tried all settings, and the players definitively do not behave has they used to unless it is a video without the lines.
I am now running ClamXav to check if anything is coming up. Thats going to take a while.
As Apple changed something?
Thanks

Transferring internal and optical drives?

Hi all,
I have an older MacBook Pro 2,2 (Intel Core 2 Duo, 2.33GHz, 3 GB RAM) which has small internal drive and an optical drive that is starting to become buggy.
I have access to a more recent MacBook Pro 4,1 (Intel Core 2 Duo, 2.6 GHz, 2 GB RAM) which has a much larger internal drive and a working optical drive.
What I want to know is, can I swap my current internal drive and optical drive for the other MacBook Pro's?
The execution of the two procedures does not bother me as I have some experience doing tech work on laptops. Just want to find out if this is a doable thing.
thanks in advance,
J

The hard drive maybe, the optical drive no due to DVD copy protection schemes requiring a tie in with original hardware.
You will have to erase the hard drive and reverse clone or reinstall OS X as the hardware drivers are incompatible in most cases.
Older computers usually have older SATA connections, so it doesn't make sense to switch hard drives between models of varying years.

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?
I use a Mini as the family media center and would like to have 5.1 or 7.1 sound for films but don't want a huge piece of eletronic equipment (I have one of those, but it isn't hooked up because it doesn't fit on the bookshelf). Years ago I used a PC and still use the Creative Audigy speaker system (Jimmy rigged to the Mini) that I ran from the PC. The Audigy PCI sound card obviously doesn't work on the Mini, so I just have two chanel plus sub. That has been fine since I switched to the Mini in 2007, but am updating to a new Mini in the summer and would like to upgrade my sound as well.
I also wouldn't be opposed to a USB soundcard that can drive the speakers. In fact, my wife would prefer smaller and less visible, ergo USB card hidden in the back.
Suggestions?

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

MacPro with both Leopard and Tiger drives. Want to switch iTunes How

I am running a MacPro with both Leopard and Tiger drives. I finally want to switch everything to Leopard and its drive. I have iTunes on the leopard drive but have never used it. How can I transfer my iTunes music, iPhone Apps etc. from the Tiger iTunes to the Leopard with the least amount of fuss?

Hello hassiman,
For additional information regarding moving the entire library from the 10.4 partition to the 10.5 partition, see this article:

If your iTunes Library is substantial, you may want to consider backing it up to an external location as well:

Setting up new MBP with SSD and optical drive and restoring from Time Capsule

Hi Everyone-
Sorry if this has been addressed before, but I couldn't find a specific answer by searching. My last macbook was stolen, but luckily I had everything backed up in my Time Capsule. I just ordered my new Macbook Pro (13"), 16GB Ram, and a 240GB SSD. I plan to install everything next week. My plan is to keep all of my apps and working files on my SSD and use my 2nd hard drive for data storage and possibly my itunes library. My question is- when setting all of this up, what would be the best way to go about doing this.
1.) Restoring my time machine backup to the original hard drive, move it to the optical drive bay, and then copy over the files that I want on the SSD (after installing the operating system) and delete them off of the origan HD.
2.) Restore my backup to the SSD (once it's installed) and then move files over to the formated original harddrive in the optical bay. My problem is that there may not be enough room on the 240GB SSD.
3.) Is there a way to do a slective restore through TM and move where I want to keep them? I think this would be the easiest.
4.) Other way that I haven't mentioned
Thanks for any help with this question.

I used setup assistant last time when I changed from a 2009 mini to a 2010 mini. It caused some file permission errors that still persist today with iPhoto. I have 2 accounts on my mini, 1 for my wife and 1 for myself, but I store all our photos and videos on the shared folder in order to avoid duplication. But when she imports pictures from her profile and I try to view them full screen, I'm unable to. I have to relaunch iPhoto and repair file permissions if I want to view them properly. I was hoping to avoid this happening again.

IMac (21.5-inch, Mid 2010) - CPU and Optical drive fans rev up to 4000 rpm

Hello,
I just want to share my experience with my rather new Imac
I bought this Imac last April and I had the fans roaring after 2 weeks of light usage. I followed instructions like resetting the SMC, unplugging the imac and restarted.
However, I started installing other software like Paragon NTFS, VLC, Firefox and also Istat nano. This happened on a more regular basis and istat nano was showing up fairly normal temperatures - an average of 50° C and I had the CPU fan at 3800 and the Optical drive fan at 4200 rpms. According to apple support, at this temperature fans should be running at factory level or a bit more. Even when I stop all activity, the fans keep up and does not stop even after a couple of hours of inactivity on the imac. Apple support recommended that I reinstall macos on a new partition and run tests and during the tests, the only software I installed was istat nano and still got the fans going with the same result - required a shutdown to bring fans at normal levels and yet average temperatures were around 50 - 55 °C.
Eventually got apple to replace heat sensors - this did not help - still got the same unwanted result, fans reving up to 4000 rpm and not stopping and all that without going above 60°C. I was at the stage to demand a complete replacement but decided to give it another couple of weeks testing.
Last test, a complete reinstall of the OS and this time, without any other software apart from standard software delivered with the mac. Ran a few things like importing over 10,000 pictures with iphoto and some other stuff to increase activity - overall CPU usage was at 5% idle for a good few hours and could not reproduce the problem (istat nano was not installed, so I could not monitor temperature). I started installing Paragon NTFS for mac and ran the same scenarios and still no fans going crazy - putting my hands over the top of the imac, can feel a slight breeze...).
Installed other software such as VLC and Firefox 5.0 but still no istat nano and same high activity, import high volumes in iphoto and also did an empty secure thrash to increase load. CPU usage was to 95 again and still fans are behaving properly.
One thing that comes to my mind with istat nano is that, when the fans get going, the ambient value change to -140 - I do not want to rush into any conclusion but is it possible that there is some interference between istat nano and those new sensors that have come in with Imac mid 2010 (from reading mac forums, Apple has added a new ambient sensor..). Because all the time I have been reinstalling the OS, I have always installed istat nano to monitor temperature and fan speed and I always got this issue. But since yesterday, I have installed clean OS, tested, added some 3rd party software but still no istat nano and I canot reproduce the issue. I have been using the same scenario during all this testing - very high import with iphoto, viewing a film, empty secure thrash, enough to use up to 95% CPU.
Has anyone experienced this? I hope this is the cause of my problem because this mac is making my life easier at home compared to previous PC and also, I want to know that my hardware is not at fault...
I will keep you posted if I get the issue again - could be tempted to install istat nano and run the tests to see if the fans will rev up after this but not sure I want to go through another 4 days of just doing this...
regards
Philip

I can't install Snow Leopard on a brand new hard drive with a brand new optical drive.

I need help please. I have a 2009 MacBook Pro. The hard drive crashed a while back so I bought a new one. The original Snow Leopard disc that came with it was scratched so I bought a new one of it as well. After trying/failing to install Snow Leopard on the new hard drive about a dozen times I bought a new optical drive as well. I installed the new optical drive today, tried to install Snow Leopard again and STILL got the same installation error messages. Any help that anyone might be able to provide would be greatly appreciated.
Last error message:
Install failed: The Installer could not copy the necessary support files.

Did you partition and format the new drive first?
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Upon completion quit Disk Utility and return to the installer. Complete the Snow Leopard installation.

USB trackball and optical drive do not work in Windows

When booted in Windows, my new MacBook Pro -- which has no internal optical drive -- does not recognize a USB trackball or my new USB optical drive. Neither appears in the Windows control panel. I downloaded the recommended driver for the trackball, but although I can find the driver installer in Windows' downloads, when run it has no effect on the trackc ball. I worked with two senior Apple support technicans on this problem to no avail. Mac OS 10.10.2

BC is short for Bootcamp Drivers. These drivers support Apple-specific hardware on your Mac. They can be found at Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support . Assuming you have a 2014 rMBP - Boot Camp Support Software 5.1.5640 should be installed on your MBP. Do you have a Boot Camp option in Control Panel -> System? If yes, then you can Boot Camp: Install or repair Boot Camp drivers and test the devices?
After you plug-in these devices, do you see any unknown devices (with a yellow triangle and exclamation mark) in Control Panel -> Hardware -> Device Manager? The Apple SuperDrive driver is included in the BC drivers bundle 5.1.5640.

IMac G5 Won't Boot and Optical Drive Won't Read Correctly

I have an iMac G5 17" 2.0GHz with a 300GB SATA drive installed about 6 months ago. Everything was fine until it recently ceased booting completely--it gets to the blue screen but the progress bar never even begins and there it sits. The fans come on fast and loud almost right away. The hard drive reads in the System Profiler, but doesn't show up at all in the Disk Utility; Disk Warrior 4 replaced the directory with ease and it appears on the desktop in TDM. It will not under any circumstances boot from a Mac OS X system disk, but will boot from the Disk Warrior and TechTool CDs. As a sidebar, the optical drive is making all sorts of loud unusual noises and reads only as a CD-ROM in the System Profiler (in the Disc Burning Tab nothing appears) even though it is a superdrive. 10.4.9 installed.

If you have AppleCare, suggest that you contact them and/or their Online Chat Support.
Also, see if your computer qualifies for one of the G5 iMac Repair Programs

MBPro (250GB, 15") freezes and optical drive noise

New MBPro. Two times in last few days optical drive made constant, repeated sorta 'eject' noise along with laptop freeze. I got impatient after a few minutes and rebooted. Any idea what is going on? More info: only has happened with Snow Leopard. Both times I had Microsoft Exchange Server email connection to my work. Nothing else in common with both incidences.

Welcome to Apple Discussions!
Your Mac should not be freezing. Have you tried running the extended version of the Apple Hardware Test?
Since the Mac is so new, you might want to just report the problem to Apple or make an appointment at an Apple Store to have this problem evaluated. If the freeze is hardware related, only they can fix it. If the Mac is really new and has a hardware problem, you might even get a replacement.
Good luck!

X61 with Ultrabase X6, no optical drive

I just aquired an X61 with an X6 Ultrabase. The X6 Ultrabase is P/N 42W4635 and FRU P/N 42W4634. The part number on Lenovo's website appears to be 40Y8116 though, so I'm not sure if it's the same part. Mine does not have an optical drive in it, so I would like to purchase a DVD burner. External is not an option. Will any slim IDE DVD burner work, like these on NewEgg, or do I have to buy one directly from Lenovo?

I did a search for that part number and I received this link Alternate part numbers for Ultrabase
Looks like you have the right one. As for using any type of slim drive, I'm not sure. Best bet is to go with the Lenovo models.
