V240 - removed optical drive, now having constant HBA (ata controller)reset

Hi there,
I have 2 Fire v240's - and only one working DVD optical drive which I move between them.. Running Solaris 05/09, whichever machine doesnt have the optical drive physically installed, goes through a continuous routine of resetting hba and trying to re-sync with it..

There is surely a way for me to disable the controller or advise Solaris to stop trying to talk to the missing hardware (DVD drive)?
Many thanks!

Humm, can you see the DVD somehow in cfgadm -l or cfgadm -lv? If so you should be able to unconfigure or disconnect it from the OS :-)

Replaced optical drive now locked out of hard drive hdd start up drive will mount

replaced optical drive now locked out of hd start up drive will not mount can some one help me

I didn't ask you if you thought you ordered the correct optical drive...
You opened up the machine. You made a change. Now it doesn't work. Reverse what you did and see if it works again. I'm assuming that the machine actually worked before you did this, right?

Remove optical drive?

Hi,
I have an older MacBook Pro 15" (2.16 GHz) whose optical drive is no longer recognized. I have purchased an external drive as replacement. My question is whether removing the optical drive will make my MacBook clumsy because of weight distribution. I'd like to lighten the load, but not if my laptop becomes much more likely to be dropped.
Has anyone tried this?
Thanks!

Yeah, i just started having this problem recently. My computer would not read any media of any kind, had a hard time reading DVDs, would only read about 2 out of 10 CDS i put in the computer. After looking around on the forum for a while, cleaning it with air, preforming a safe boot, cleaning the directory, making sure i could do everything i could do, I finally decided to get a new drive. I took it to an authorized mac retailer/repair center today, should have it back in a day or two. sigh. Luckily, I bought the applecare package.

Removing optical drive from PPC G4

I have a superdrive from my G5 that I want to put into my G4. Can someone point toward a tutorial on how to remove the G$ optical drive? I cannot figure out the mounting. It apears to be in some sort of carrier with the zip drive that must be removed befoe the drive can be removed.

ilovetrainskc,
Sorry, I misinterpreted the G$ in your original post (Can someone point toward a tutorial on how to remove the G$ optical drive?)as G5. Therefore, I assumed you were having difficulty removing the optical drive from the G5.
Had I know that your problem was part removal from an AGP Graphics G4; I would have provided you the following Apple DIY link:
<http://docs.info.apple.com/article.html?artnum=75312>
It relates to Gigabit Ethernet G4s, but the AGP Graphics G4s are almost identical (many Apple Support documents cite use for PowerMac G4 (AGP Graphics/Gigabit Ethernet). I've never been able to find Apple DIY documents or CIP documents strictly for the AGP Graphics G4, but these worked quite well for me when upgrading my friend's 350 MHz AGP Graphics G4 (aka., Sawtooth) last year.

MBP - Remove optical drive to save weight?

Hi,
Is removing my MBP optical drive save a lot of weight?
Thanks

... because the Optical Drive is very light indeed.

Replaced Optical Drive now Mac book will not boot up

I bought a second hand Mac Book Pro A1150 model. It did not have an optical drive so I bought one, installed it and now my Mac Book will not boot up. When I take the drive out the Mac Book boots up fine. I was told that the optical drive although used was tested and work when it was shipped out. I'm a little new to Macs but not new to working on computers. Is it common for a possible defective optical drive to casue a Mac Book pr to not boot up or does this sound like an issue with the optical drive cable, or possibly the logic board?

That is true. I cannot think of any way to test the Optical Drive without swapping it into a known correctly operating MBP.
A thought which probably may not be an issue. When I installed an Optical Drive in my old (2006) MBP, I remember seeing in the instruction manual an item called a grounding pad (which looked like a tiny steel brillo pad with out soap) which was missing in mine. The MBP worked and I essentially ignored it. Perhaps that may not be case with your situation.
My thoughts are that the Optical Drive is malfunctioning and the cause of your problem. Perhaps you should consider getting a new replacement from OWC. But that entails a $100 risk with no guarantees of success.
Ciao.

Stripped screw to remove optical drive

Hi everybody,
I'm trying to remove the optical drive in my Macbook pro 2011.
I want to add a second drive.
Problem is, one of the screws to remove in order to do it, is Stripped..
My computer is still under applecare.. Would Apple accept to help me out with this ?

Nope, but you might find a sympathetic Genius that has a trick to get it out.
If AppleCare finds out you tampered with the optical drive, it's voided you know.
Or you can visit the hardware store(s) and find a stripped screw remover tools.

I have an old powerPC G4. dual 867 512 MB. my optical drive is having trouble reading my leopard installer. I was going to try to use remote install but i don't have a network where I can connect both the mac and the windows laptop. any suggestions?

I'm just trying to revive my old PowerPC G4/ dual 867MHz 512MB. Unfortunately I am unable to install from disc since my optical drive, although still working, is somehow not able to read the leopard installer. I wanted to try the remote install option but have limited resources and don't have a network where I can have both the Mac desktop and windows laptop communicate. I read somewhere that I can use a crossover cable to connect the two directly. I'm still trying to see if I can get an external DVD-ROM as another option. Any suggestions?

Your Mac doesn't need a crossover cable, it auto-switches...

But I have no idea how that will help you install from a Windows computer.
If you get an external DVD drive it needs to be Firewire & Mac bootable.

I replaced optical drive, now MacBookPro is very hot and wifi hardware not installed

My late 2008 MacBookPro 5,1 2.53 GHz laptop's optical drive would not record last week. A lens cleaning didn't help, so I replaced the optical drive Tuesday evening with iFixit instructions. Other than stripping one of the screws holding the drive in place, all seemed pretty straightforward. I had to disconnect the camera cable to get the drive out but replaced it. After putting everything back together, the new drive seemed to burn discs well and everything (including the camera) worked perfectly.
Last night I came home to the laptop, which, as usual, was sleeping and connected to the AC adapter. Not as usual, it was really hot. I restarted it and when it rebooted the wifi icon had an x in it and said wifi:hardware not installed.
I reset the PRAM and the SMC. No luck.
I have an appointment to take it to a genius bar tomorrow afternoon, but what could I have done without realizing it?
Thanks for any suggestions (I have been working on Mac desktops and laptops for a number of years...this is the first time anything like this has happened to me...)

P965 Platinum 2 optical drives leaves no room for ATA Harddrive??

Since there is only 1 IDE controller, I can't run 2 optical drives and have a IDE harddrive hooked up together?? I'm builing a system for a friend and along with 2 optical drives(DVD burner and CD ROM) he wants to use his current ATA Drive as storage. I am upgrading him to WD 250GB SATA drive. I just realized tho this board only has the one ATA connector and I can't hook all 3 devices to that controller. Do I have any options other than losing access to 1 optical drive?

You can put in an addtional PCI/PCIe-IDE Controller Card OR use a PATA->>SATA Converter.

Raid array removed, hard drives now wont work?? help

Hi all,
I had a KT266 pro2RU motherobard with 2 ibm 40gig hard drives that were in raid mode 0,
I took the 2 drives out of the computer and wanted to use one of them in another computer on a standard drive controller (single drive not raid) and i cant seem to access the disk to format it or install windows xp on it?, it keeps saying write access denied?,
I am thinking that i should have unmounted? the raid array before taking the drives out to put them back to normal but dont have the raid system any more, is there any way i can make these 2 40 gig drives work now?, or has it overwritten the HD bios or something?
If anyone can help i'd appreciate it
Cheers

i would try fdisk on it or partition magic if you have that

Replaced iMac Hard Drive, now having trouble getting TM back working

The drive on my iMac failed and was replaced. I used Migration Assistant to get data from my Time Machine backups (on 1TB Time Capsule) to the new drive--no problems! (Time Capsule is connected to my iMac by Ethernet as the wireless part of TC doesn't work anymore.) Now I'm trying to get Time Machine back working with this new drive and would like to continue from the backups I have. However, for several hours all it has done is cycle through Calculating Changes to Cleaning Up multiple times. When I look at the TM prefs, it knows the oldest backup was on Feb 28 before the drive starting failing, so I know it's seeing the backups on the TC. I believe I read that because of the new drive the first backup would be a full backup. However, for several hours all it has done is cycle through Calculating Changes to Cleaning Up multiple times.
I've been reading through some of the discussions and the tips at top of page, but am still not sure what to do. Is there something I can do to get this working from where I left off, or am I just going to have to reformat the TC and start over?
Thanks for any help/suggestions.

On a Time Capsule, deleting a lot of old backups is an excruciatingly slow process.
TM must delete the oldest backup, dismount the sparse bundle, compact the sparse bundle, then mount it again to see if it's made enough room. This can go on (as you see) for a very long time, even via Ethernet.
Since Time Machine will never delete the last remaining backup, it needs twice the space of the data it's backing-up, plus 20% temporarily for workspace. So if your TC isn't 220% the size of the data on your system, the backup will (eventually) fail, and you'll have no choice but to delete the sparse bundle.
On the other hand, if it's considerably larger than that, you can speed the process up a bit by manually deleting several old backups at a time, then compacting the sparse bundle yourself, per #12 in the Frequently Asked Questions *User Tip,* also at the top of this forum.
Click here to download the +Time Machine Buddy+ widget. It shows the messages from your logs for one TM backup run at a time, in a small window. That will show how much space it needs, and how much is currently available, so you can determine how to proceed.

Optical drive not recognized as an ATA device in Apple profiler

The dvd drive is not recognized any more in Apple Profiler (nothing under ATA) and the CD or DVD are not recognised neither. I can hear the drive is working but that's it. The problem happened just after I upgraded to 10.4.10. Any help would be welcome!

You will want to ensure your USB DVDRW drive is properly connected to the Windows 8 VM in question.
To check this you will want to use the Vmware vSphere client to connect to your Vmware ESX/ESXi host.
Next, you will want to edit the settings for your Windows 8 virtual machine and check that you have added a USB controller and then connected the USB device to the controller. This is a manual assignment. If your DVDRW drive you wish to connect is actually
connected via SATA on the motherboard of the host then you will want to go through the same process to ensure the CD/DVD drive of the host has 'connected' and 'connect at power on' selected under settings.

(TP A21m) Optical drives (CDRom, etc.) only work in safe mode after installing IBM RecordNow

Two days ago, I put in a new IBM CD-RW/DVD Combo IV drive into the Ultrabay 2000 slot of my TP A21m 2628, and using the accompanying IBM software CD, installed the IBM RecordNow program. After the re-boot, the operating system (Windows 2000 SP4) failed to recognize any of my internal or external optical drives. They all stopped working in normal mode. What happened? What is suddenly blocking all of my optical drives?
They all work perfectly fine in safe mode; my internal optical drives work perfectly when being tested by PC Doctor; they show up in the "Safely Remove Hardware" list; and Device Manager indicates that the drivers are installed, enabled and working properly. (However, there is no "+" next to CD drive in the boot sequence of the BIOS Setup Utility). The BIOS is the latest version, IBM/Lenovo drivers and software have been kept pretty much up-to-date, and the operating system was always kept up-to-date. I have run system file checker and so on.
I uninstalled the IBM RecordNow, removed the Combo drive and re-inserted the original CD-Rom drive, but that made no difference. So, with the Combo drive back in place and (using means other than the CD-drive) I reinstalled the original IBM RecordNow and proceeded to install the update from Lenovo (specified for my Combo drive and Windows 2000) in the hopes that the update would fix the bug. But, the update wouldn't install and no explanation was provided.
I am quite sure that it is not a hardware problem, particularly since everything is fine in safe mode and under PC Doctor. At a minimum, I would like to get my computer back to the way it was before I put in the Combo drive two days ago - with a working internal CD-Rom drive and a working external CD-RW drive. Right now I am without any optical drive functionality, like I was way back in mid-1990's. Thank you for your help.
Solved!
Go to Solution.

The problem has been fixed as follows: I modified the registry in accordance with the Microsoft instructions at http://support.microsoft.com/kb/270008/ : "... Remove the Upperfilters and Lowerfilters values completely from the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}…"
After the reboot, the operating system once again recognized the optical drive. Having modified the registry, I then had to reinstall ITunes. After that, I successfully reinstalled the software from the IBM Software CD. Everything seems to be fine now.
(The update for the IBM RecordNow still refused to install, but I probably don't need it anyway. I have not bothered to check whether the external optical drive works or not, and I don't see any need to do so at this time.) Thank you

Windows 7 won't boot without optical drive (SSD, Dual HD)

I recently purchased an SSD and an optical drive HD caddy so I could use two HDs on my macbook pro. I installed the SSD in the normal HD slot in order to install Windows via optical drive. When I move my SSD over to the optical drive slot, Windows hangs on a black screen before the Windows logo and never boots. I tried moving the SSD back to the main HD slot but without the optical drive installed, the same symptoms occur - no boot. This leads me to believe that Windows will not boot without the optical drive (which was present during installation).
Perhaps this is a problem with primary/slave drive settings? I learned today that the intel chipsets in macbooks do not have BIOS for Windows and do not allow you to access the EFI. Not sure if that would help anyways.
Has anyone experienced this and/or have a solution?

I am suffering the same issue. Macbook pro 15 inch late 2009 with 8gig ram. I have a 256gb ssd newly installed, a dead superdrive (thanks a bunch for the drop in build quality without the drop in price apple) and an optibay caddy which i intend on having my 500gb 7200rpm previous HDD installed in. I had the normal annoying issues trying to get bootcamp working with an external optical drive. I then had the bright idea of taking my external optical drive case apart and discovered its a sata drive with a sata to usb convertor attached. Got bootcamp/win7 installed fine using the superdrives sata connector with the optical drive (essentially having a temporary internal optical drive again).
OSX and windows function fine as long as the optical drive stays connected. There does not need to be a disc in the drive, i thought windows might be getting boot info from the win disc. Osx boots fine if its just the ssd. Windows hangs with a white screen right at the beginning. Also doesnt boot using boot menu via alt key. Nor using the reEFIt boot menu (installed later now deleted).
Disk utility says it cannot repair the windows partition and says to back up the data and reformat the drive. This also happens if i use a normal sata drive. I am attempting a few more ideas but at this rate i will be virtual machining windows instead. Far from ideal but seeing as my windows pc is now officially no more and there are two pc only programs i need to use for university i dont have much choice i NEED windows. Anyone got a bright idea that may help?
