T42P Won't Recognize DVD/CD Drive

My CD drive isn't recognized. Can't find it in Device Manager (WinXP). Can't find it in Tool Box diagnostics. System won't boot from CD drive, which leads me to think it's a hardware problem and not an XP problem.
I'm told it's probably the motherboard, but I'm wondering about BIOS. A few boots prior to the development of this problem, I had two instances where when I booted, there was no current date in BIOS and I had to set it to continue. I ordered a BIOS battery but, before I could change it, the BIOS clock/date problem went away.
Now I have this weird problem with the optical drive. Is there a way to force a BIOS update? I alredy have the latest version and when I attempt to update it, the update program tells me I've already updated to the latest version and will go no further. I'd really like to force a reflash to see what happens.
Perhaps a command line switch to force the BIOS update program? A way to flush out theBIOS?
Any thought would be appreciated.
Solved!

One addition to prevent misunderstanding:
You'll need to measure the resistance of the fuses between their soldered ends. If resistance = 0, the fuse = OK, if "1" or endless, then fuse is blown.

IMac won't recognize DVD/CD drive anymore

As the title suggests, my iMac won't recognize my dvd drive anymore.
I don't know what the reason is for it.
I've never had this problem before, it happened a couple weeks ago.
I first noticed this when I tried burning a CD in iTunes.
It said at the top of the screen "Disc burner or software not found..."
I then went to System Profiler and checked "Disc Burning" and it
read, "No burning device was found. If you are using an external device please make sure that it is connected and powered properly." I'm not using an external device. I'm using the DVD drive that originally came with my iMac.
If anyone could please help me out with this I'd be very grateful.

Lately, I left my iMac on while I was sleeping. Couple nights ago, the optical drive made a funny noise and woke me up. It sounds very similar to opening up Disk Utility on my MacBook Pro, it looked for the internal optical drive. First, I didn't do further investigation on my iMac.
Yesterday, I happened to do some 'housecleaning' and attempted to slide in a data CD. The drive didn't response, so the CD was stuck. In the past, I had opened up numerous iMacs and they were getting more complicated model by model. I am certified to perform the repair, but since this iMac is covered under AppleCare, I decided to make an appointment with the MacGenius.
I did perform a PRAM reset earlier.
Do you have 'put the hard disk(s) to sleep when possible' checked under Energy Saver?
Out of all the Macs with slot-load optical drives built-in I have owned, this is the first malfunctioning I have ever had.

Hi, since i put some mp4 video or DVD files on my external hard drives final cut prox won't recognize my hard drives, i move all the video files and the problem still exist. somebody have the solution

Hi, since i put some mp4 video or DVD files on my external hard drives final cut prox won't recognize my hard drives, i move all the video files and the problem still exist. somebody have the solution

Did the back and forth between PC and Mac file systems screw up my files somehow?
Yes. Unfortunately the move has almost certainly caused the loss of the resource data that would have been (invisibly) attached to those files.
By adding a specific .mov extension after the fact you will have helped the Mac correctly identify the file type / asscoiations but also significantly you will have physically changed the filename eg from "clip" to "clip.mov". This means that when you come to reconnect the media in FCP , then FCP will be looking for files that no longer exist at the given path eg when specifically looking for our example clip called "clip" of course it won't find it.
Try this as a test... first remove the ".mov" extension from one or more of the clips, select those clips and press Cmd-Opt-I to open an Info window for the selection. You'll see an "Open with:" popup and in that popup you should choose QuickTime Player (if its a Unix Executable then it will initially list Terminal as the appropriate app, you have to choose Other... then in the open dialog choose Enable > All Applications and then navigate to and select the Quicktime Player app as the appropriate app). After you've done that restart FCP and see if you can now reconnect to those clips.

It often fails to boot with the circle with slash. Tried safe boot (works), tried booting from optical drive with original system disc (won't recognize or eject-tried all of the eject techniques), and ran disk repair in target mode (found nothig wrong). Can't run hardware check for obvious reasons. It does not see external drives connected to FW or USB ports.I am starting to suspect a bad logic board. Any thoughts?

I can no longer startup from a CD/DVD
Be sure you're inserting the DVD that came with your Mac Pro. If you are trying to boot from other optical media be sure it is compatible with Intel Macs and specifically the Mac Pro. You are probably trying to boot off a discs that does not have a suitable OS on it.
or my external FW drive which has 10.4.8 also installed on it (pre-intel)
Same goes here. Your FireWire drive does not have a suitable OS installed in it. You need to install an Intel version of Mac OS X. Additionally you will probably need to repartition your drive using the GUID Partition Table. Until you do both of these Startup Disk will not let you select it.

? MacBook won't recognize external disc drive

My MacBook's internal disc drive quit, so I'm trying an external Samsung SE-208 slim portable DVD writer.   It worked once, but now the mac won't recognize it. I tried a DVD switcher app - no luck. The Samsung plugs into the USB port, starts up OK then disappears from itunes, the desktop, Finder - It's gone. Can I completely disable the internal disc drive? Would that help? I appreciate ANY help.   I'm not skilled at these things so you need to spoon feed me. thanks

Macbook won't recognize external Hard Drive and issues with Time Machine

Hello everyone,
I have just bought a new Macbook Pro with Mountain Lion and I am currently having problems with Time Machine.
The issue begun in Snow Leopard: Time Machine was taking too long to backup, and would often not finish the backup because the external hard drive would be unwillingly ejected.
Now with Mountain Lion I have reformated the drive (Mac OS Journaled) and about a third of the way through had the same issue: the drive was ejected before the backup could be finished. I restarted the machine and it happened again. However, now the computer won't even recognize the external drive when I plug it in. I have also tried to power off/on the drive itself to no progress.
I have tested the USB port with another drive and the port is fine. I have also tested the usb cable and it is fine. And Disk Utility does not recognize the drive (even when I try the >diskutil list command in terminal).
Now, I can hear the drive humming normally when I turn it on, and it is not usb-powered (my electricity current does fluctuate).
Could the interrupted backup procedures have damaged the drive? And if so, wouldn't the computer recognize it anyway?
It is a 4 year old WD 1 TB that is used exclusively for TM and has never left the house.
Thank you for your time reading this and let me know if you need any more information that could help out.
Cheers!

From your description, I'd suspect a failing drive. Maybe time for a new external, especially as you've already re-formatted and it's still playing up.
I had a similar problem with one of my clone backups a few weeks ago - it failed, I erased it, re-cloned, worked a couple of times and then it failed again. Disk Utility didn't throw up any errors after re-formatting. I guess all disks die at some point.

Clean Install of 10.8.2 Won't Recognize the BackUp Drive as a Valid Time Machine Drive. Applications Needs to be Restored

Hi, for some reason my clean installed 10.8.2, when I use the Migration Assitant won't recognize Time Machine [It's mounted alright (Firewire 800 with green icon with the Time Machine logo) Western Digital, My Book Studio model. I probably should have opted for Apple's significantly expensive Time Machine when it comes to integration and backup]. It would go into Time Machine but the Restore would be dimmed out. All the snapshots are from Mountain Lion; I'm wondering why it's not compatible. If I try to restore the Applications it won't let it. I've manually copied the Documents, Desktop, Downloads, Movies, Music files but I can't find the the Applications folder in that external backup drive to copy from or at least see what apps I've installed and reinstall them.
How do I go about at least viewing what apps are in my latest Time Machine snapshot so I can reinstall- a blessing in disguise coz' at least it'll be more streamlined. It's prudent, by God's grace that I have another USB external drive with Snow Leopard on it to run some apps I've used before doing the clean install (I had to erase and zero-out the hard drive for security because it's part of the Apple hardisk replacement program which I'm thankful for- AppleCare is worth it for very expensive gadgets like this late-2009 iMac. Reinstalling and putting things back to normal is a little tedious, thankfully there are other projects to be busy with while it copies and downloads updates).
Thank you in advance.
God bless.

Hi. Thanks for the reply. Does Time Machine by default exclude System and Applications Folder (I didn't click any option to exclude those I remembered)? How do I not exclude the Applications folder and System files this time around?
In Time-Travel view when I point it to the Applications folder, it switches to the Volumes folder and the Restore is dimmed. I wonder if it's incompatible because it's not Apple's Time Machine or it's a bug with Moutain Lion (the drive is backing up the new clean install of Mountain Lion now but when I test it, use Migration Assistant if I need to restore things again, it still doesn't see it as a Time Machine backup).
What could be the solution? Should I reinstall my applications again (I guess that's a blessing in disguise, now I can declutter)?
Thank you.

MacBook Pro won't recognize 1TB external drive

Hey team,
My mid-2010 MacBook Pro won't recognize my WD My Passport 1TB drive. I was copying files from the drive to my computer when my computer went to sleep (didn't run out of power, just went to standby mode). Turned computer back on and now it won't recognize the drive.
It is a USB 3.0 cord (computer is only USB 2.0 and the cord works with other drives) and when plugged in, the light turns on and the disk spins but isn't recognized my this or other computers (also not in Disk Utility).
Tried a handful of disk recovery programs but nothing wants to 'see' the disk plugged in.
Thanks for any and all suggestions.

yes yes yes, I warn people about WD drives on this link:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
theReKleiner wrote:
What now?
Only option is to buy the SAME exact HD and swap controller boards, or pay someone a LOT more $$$ to do the same thing.
its not soldered there, its just a controller/ SATA "one piece"
They do that to save 50 cents in mfg. costs.
I mention your "issue" in that link. Which is why you do NOT buy WD ext. HD.
they make the controller board and SATA card one piece.
CURRENT MFG. THAT HAVE controller board and SATA cards as one piece are : WD USB drives, and Toshiba USB Canvio
However Toshiba didnt USED to do that, but they started doing it at the end of 2013.
avoid those 2.
To avoid that nonsense, buy Hitachi drives in USB.
Or, the best option:
Save money and invest in a bare hard drive backup and redundancy plan
Its cheaper
less fuss
more reiable, removes the nasty failure point of SATA card interfaces.
takes up lot less space.
Bare hard drives and docks. The most reliable and cheapest method of hard drive data storage, archives, and redundancies
The best method for your data archives and redundancies, which is also the least expensive, the most reliable, and the most compact option is the purchase of naked hard drives and at least one USB 3.0 HD dock ($40 roughly).
While regarding Time Machine and your Macbook or desktop, your primary backup is best saved to a conventional USB (or Firewire / thunderbolt) hard drive inside an enclosure, the most important part of your data protection begins after your 1st / primary Time Machine / backup; and these are your secondary (most important) data storage devices, archives and their redundancies.
However bare hard drives and docks (below) also work perfectly as a Time Machine backup, this is for home use, since the docking station is certainly not very portable as a notebook Time Machine backup device should be; nor should bare HD be packed around with a notebook, rather remain at home or office.
Six terabytes of 2.5" HD pictured below in a very compact space.
Bare hard drives and docks have the lowest cost, the highest reliability, and take up the smallest storage space
Drawbacks:
1. Care and knowledge in general handling of naked hard drives (how not to shock a bare HD, and how to hold them properly). Not a genuine drawback.
Advantages:
1. By far the least expensive method of mass HD storage on a personal basis. Highest quality naked HD can be purchased in bulk very cheap.
2. Eliminates the horrible failure point of SATA bridges and interfaces between external drives and the computer.
3. Per square foot you can store more terabytes of data this way than any other.
4. Fast, easy, no fuss and most simplex method of data storage on hard drives.

Satellite A135-S2356 - BIOS won't recognize SATA Hard Drive

Hello everyone, hope you can help me out.
Got a used Satellite A135-2356, everything looks fine but BIOS won't recognize SATA HDD, shows no disk, downgraded BIOS to 1.30, no good, upgraded to 1.40, no good. BIOS has no options to change/test/detect HDD/SATA settings. Tested hard drive in another laptop and reads it fine. Got restore CD (Vista Basic 32) from Toshiba but since BIOS won't read HDD, can't do anything. Cleaned contacts, no good. This HDD must be too large or something for the board.
*Hitachi HTS541612J9SA00, 120GB SATA, 5400 RPM*
Thanks for the help!!!

Hello Richie
To be honest I do not believe the HDD is too large for your notebook. I can imagine your notebook can handle with 160 GB HDDs too. Unfortunately there is no public document about HDD upgrade possibilities. I can imagine that ASP in your country has info about this stuff.
It is also pretty strange that HDD is not recognized properly. Long time ago I have had the same problem. Every time when I have used F12 at the start up HDD were not listed as bootable device. Solution in my case was to set BIOS to default settings. I believe your BIOS has already default settings but try to do this again.

AirPort Extreme (MC340AM/A) won't recognize USB hard drive

Hi,
It was working fine (at least that's what I believe) to one point, and then all of a sudden, AirPort utility won't recognize my external HD connected to USB port of my AirPort.
Just to eliminate possible confusion... drive is formatted as Mac OS Extended (Journaled) and I had another one as well, sitting on my desk that's formatted as FAT32. Both of these drives were connecting fine to AirPort utility till last night. All of a sudden, absolutely nothing happens when I connect either one of these two and turn it on. AirPort Utility/Disks pane shows: NO DISKS FOUND.
I even replaced this USB cable just to eliminate this possibility, still nothing.
Could it be that my USB port just died? I have 14 days to return it and I'm on my second day, so I want to know before I run out of my return bonus.
Thanks in advance!

OK, I just tried another external HD. This time it was LaCie 1Tb. As soon as I connected it, it was recognized by AirPort Extreme. What's puzzling is, that same thing happened with my SimpleTech 1Tb one last night. It was easily recognized by AE and then all of a sudden AE would never recognize it again.
At first, I though maybe these HDs are not supported by AE, but that's not the case. One is LaCie with Samsung HD103UJ drive inside purchased at Apple store, another one SimpleTech with WD inside, and other two are both super reliable Sygate HDs (never ever had any problems with them).
Hmm... I just disconnected LaCie one and tried SimpleTech one more time and it worked. AE can see it again. What's going on in here? Something is definitely not right.
Can't test this port through printer since I don't have one available at the moment.

Lion: Time Machine won't recognize my book driver?

After upgrading to Lion, TM won't recognize mybook drver. It says "The version of the server you are trying to connect to is not supported. Please contact your system administrator to solve the problem." This Wester Digital drvier is been connected via airport extreme for almost a year, and it worked fine on Snow Leopard, since the upgrade it does not see my backup driver. Any ideas?
Thanks.

Same problem here, with Western Digital BlackArmor NAS220.
It seems that Apple changed something with its AFP protocol, used by Time Machine.
In one single word: AMAZING!!!
I guess we have to wait until either Apple or WD releases some patch.

Hp recovery manager won't recognize my flash drive!

My computer is the HP Pavilion p6-2317c Desktop PC, running windows 8.
I'm trying to create recovery media, and have a 32Gb Sandisk Cruzer Facet that I was intending to use for it. Unfortunately, Recovery manager doesn't recognize the flash drive...it never shows up in the menu at all. The drive shows up when I click the computer icon in the files section, with no issues at all, as you can see.
I haven't created a recovery media set, and it doesn't show the not enough space error, it just doesn't let it show up at all!
What can I do to fix this? I'd really like to make a recovery set, to ward off a visit from the demon in charge of foulups visiting.
This question was solved.
View Solution.

HP is looking into the issues reported on flash drives not working for Recovery creation in Windows 8. I have been told they are working on a patch/upgrade for Recovery Manager.
In the meantime, it has been suggested to either switch to DVD or pick up a flash drive that is NOT logo'd with the Windows 8 compatible icon on package.
If neither of these is acceptable hold out for the coming patch.

Disk Utility won't recognize new hard drive

Hello,
Thanks for taking the time to read this.
The original hard drive (80 GB) went bad, so I replaced with a new 160 GB Western Digital one. I formatted the hard drive using Disk Utility from the Mac OS X Disk. It worked the first time I booted into Leopard (I just booted up to make sure the OS loaded...didn't install any new software and/or hardware).
Then I shut it down and started it back up, and the computer didn't recognize the hard drive. I inserted the Mac OS X disk and ran Disk Utility, but the hard drive was not recognized.
So now I'm thinking the new hard drive was also bad. So, I ordered another one (Seagate 160 GB) and it to was not recognized when I ran Disk Utility from the Mac OS X disk.
When replacing all of them, I followed directions I found here and other websites. They all said to do it the same way, so I'm assuming the directions for replacing a hard drive in a laptop were correct.
I searched Google and found several posts suggesting using an application called Disk Warrior, but from my understanding, you cannot run it from a disk, it needs to be installed, which is obviously impossible since the hard drive isn't recognized.
Then I ran Open Firmware and did "devalias" from the prompt. From what I can tell in the list of hardware, the hard drive is recognized, but I am not sure. I took a picture of the screen printout but do not see an option to attached it to this post. Therefore, I'll just tell what it said for now and will create an image hosting account so I can add a URL for it later.
In the list, "hd" is in the left column and in the right column of the same line is "/pci@f4000000/ata-6@d/disk@0" (without quotes).
If anybody has any suggestions, they would be greatly appreciated.

Welcome to the Apple discussions.
I've replaced a few hard drives, and in instances where it's not recognized, it's either been a cable connection issue or I've seen others with a jumper issue. Either the hard drive to logic board cable isn't properly set, typically on the logic board side, or a jumper was left on the drive, where typically you can just remove it. I haven't personally had the cable fail, however, that's possible too.
When you pulled the large plug from the back of the original hard drive, did you do it very carefully? It's not like a desktop hard drive plug that you can just pull out ... it needs to be wiggled out, gently. I have a hard time believing two new drives would be essentially DOA, although the first one worked for a bit, which leads me to wonder about the physical connections.
Since you have your original OS X disks, you could try running the Apple hardware test to see if it gives you any error message(s).
