Blu ray drive no longer recognizing dvds or blu ray discs

Until about a week ago I was able to read cds, dvds, and blu ray discs with my dv6 product number lm720av. Windows 7 64 bit. I put in a disc recently and it tries to read the disc for a couple of minutes before it stops trying and shows no disc in the drive. I looked online and it looked like there were other instances of this happening but no one had a solution. It can read cds but not dvd or blu ray at this point. I tried uninstalling the optical drive via device manager and it uninstalled no problem then windows automatically found the drive and reinstalled the drivers which did not change the results. I saw online people were suggesting running sfc under administrator mode in the command prompt. No change. Does this mean my blu ray diode failed? I see two lenses in the drive, is one cd and the other a combo dvd/blu ray? Any other suggestions?
I am about 3 weeks out of warranty on this laptop.

Hi,
The following procedure will test if your notebook can start from a bootable disc in the CD/DVD drive - the advantage of trying this is that it will rule out any possible Windows driver error as the CD/DVD drive is under the control of the Bios when starting the notebook. So if you find that the notebook will not boot from the DVD, then it's almost certainly a Hardware fault in the optical drive itself and it will need to be replaced.
Using another PC to create a Windows 7 Rescue CD and DVD. Download the ISO from the link below.
Windows 7 64bit
You need use an application such as ImgBurn to correctly burn the ISO to a DVD - a guide on using ImgBurn to write an ISO to a disc is Here. Once created, insert the DVD and then restart the notebook and see if it boots from this disc - if it does, let the first screen come up ( this will show repair options etc ) then just remove the DVD and restart. If the notebook will not boot from the DVD, it will just load straight into Windows, in which case, just remove the DVD.
Let me know.
Regards,
DP-K

Hard Drive no longer recognized on Powermac Blue & White

Hi
I,ve recently acquired a blue and white tower with the Rev 2 motherboard.
I tried to load 10.3 from black retail discs,however when it gets to "select destination" there is no disk image.It's a 350 Mhz model with 30G HD and 768MB ram.It has no PCI cards installed except the ATI graphics card.
Ant help would be appreciated as I deal more with iMac G3's.
Cheers

Hi there, it's quite likely a HD of that age has died.
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
Does it show up in DU there?

Dvd drive no longer recognized

My dvd drive is no longer recognized in my HP Pavilion dv9000 notebook. Do I need a new driver? How do I get it?

Hi,
The driver is in the operating system so you shouldn't need any. Can you see the optical drive in the Device Manager??

After security patch 03/04/2014 OSX 10.7.5, first one, then a second, external backup drive no longer recognized. Diagnostics for the FireWire one displays brand name of unit, but Time Machine and its own app don't see it. Where do I start?

Yesterday I installed the security patch, OSX 10.7.5 to my IMac that is about 2 years old.
Today my Seagate BackupPlus for Mac will power on but is not recognized. It does not show up as a device, Time Machine says the latest backup was DELAYED, last successful at 03/04/2014 9:35 PM (yesterday) and next backup would begin when the disk was connected. An error message I did not save said basically the drive was not recognized.   I did all drive's troubleshooting steps, including installing a newer version of their app. I tried swapping USB for FireWire, changing electrical outlets, etc.
It seems a bit coincidental to have 2 drives "fail" simultaneously. Is anyone else having this issue after this security patch? What would be the approach from the Mac side? TIA for any assistance.
Please see below regarding the second drive. Is this a red herring, or does it help pinpoint where the failure might lie?
I also have a Seagate GoFlex that WAS recognized until I did the troubleshooting on the other drive. When I put it back on after testing the other drive with FireWire, it now is no longer recognized.
Diagnostics says this about that:

Thirdly, in after one of the testing/reboot loops, the HP WiFi printer was no longer recognized, but after a few more it came back.

I have a similar problem.
Moreover, as my external drive is split in 2 for (a) regular storage // (b) time machine usage, I can see in the Finder that I can connect to the (a) regular storage part and use it normally (image 1).
And I cannot connect to the backup part in Finder , nor see it in Disk Utility, nor use it in Time Machine (although it's listed in the Time Machine preferences, image 2), as it does not connect (image 3).
Can somebody help?

2 TB External Drive no Longer Recognized by iMac 27"

I have a 2 TB external HD (actually two 1 TB drives housed together in a OQC Mercury Elite Case) that has been working flawlessly for about 10 months as my Time Machine backup to the iMac 27". I have it hooked via FW800.
Yesterday I noticed that TM backup failed and when playing around, I also noticed that the drive was no longer recognized. I check System Profiler and the drive was not seen. I did a PRAM reset (as this usually fixed the FW800 issues), but still no drive.
Thinking I had a faulty FW800 port on the iMac, I switched the connection to USB 2. I see the Drive listed in the USB Device Tree in System Profiler, but still nothing on Finder.
I opened Disk Utliltiy and I see a listing for a "2 TB External Raid Media" and then as a indent is says "Disk 3s3", but this is grayed out and you can not click on it to, say, repair permissions.
I installed an update late Friday night and I have no idea if this is the reason, but I am curious what the next step might be. I am using 10.6.4.

James,
There are some basics you can do to do trouble shoot the FW800 problem. First is doing a SMC reset, follow the instructions for Intel based iMacs. This letter covers multiple models of Macs and you need to follow the correct procedure.
The next item to try would be resetting the PRAM.
Finally The X Lab has written a good article on troubleshooting Firewire devices. You can locate that article here.
Hope this helps out some.

Roger

USB Hard Drive no longer recognized after SW Update

I just updated Cisco software and my external hard drive is no longer recognized by Cisco. It is a Seagate drive that is listed on the Cisco tested - passed - approved list. It worked prior to this update. I have disconnected the drive. Reconnected it. Rebooted. Turned machine and router on and off and its still not recognized. Any ideas? Thank you, Jim S.
Model name: Linksys E4200

It's great to hear that everything is back up and running.
However, just in case you missed some step while upgrading Cisco Connect or Firmware. These are the steps.

Firewire drive no longer recognized after upgrade?

having an onset of problems the last 2 weeks.
first upgraded to 10.4.6 on mac mini 1.42 non-duo, worked a few days than acted weird with apps crashing. had to reinstall from 10.4 disk. seemed ok. repaired permissions, ect. after reinstall (and a subsequent power outage) a firewire drive attached at time was no longer recognized by mac mini or connected imacG3. reinstalled 10.4.2 on mac mini. installer unable to reinstall 10.4.6., I would like to have firewire drive recognized again. when attached to other firewire drive in daisy chain, says device unrecognized, other wise unable to get any info on drive. what to do?

I am having nearly the exact same issue as you are experiencing. My Western Digital Dual-Option Media Center 160 GB FW HD is going in and out big time. It seems to be there for a time but then conks out. I have to disconnect the power and now the drive seems to be malfunctioning.
Same story with my LaCie 52x CD Burner. I placed the Disk Warrior CD in there and the computer recognized the disc at first but then spinning beach balls galore!
This has to be one of the worst updates to an OS X system I can remember. I can only think PowerPC QA testing has gone through the toilet since the Intel move was completed.

Won't eject disc- drive no longer recognized by system- 1-week old iMac!

Tried to burn something in Toast- I put in a blank DVD, and all **** breaks loose...
As long as the machine is powered up, I hear this slow "chugging" of the Superdrive, about a 4-second cycle, and in System Profiler, this is what I see:
"No burning device was found. If you are using an external device please make sure that it is connected and powered properly."
Tried to eject the disk by holding down the mouse at startup- no dice. OK, how do I eject a disc when the drive "doesn't exist", according to the system?
I don't want to reboot more than needed because I'm getting white screens and other joys when I try to do that...
Please help! It's a long drive to the nearest Apple Store...

Well, a call to Apple seems to have fixed the problem;this was the sequence:
1) shut down
2) unplug everything but keyboard and mouse (I only had a wireless keyboard handy)
3) restart, holding down P-R-Option- Cmd (Apple key)- AKA zapping or resetting the PRAM
4) keep holding down the keys, wait for 4 startup "chimes"- I only got 2 before it completed booting despite my holding down the keys
5) all seemed OK at this point; the drive would inject/read/eject a commercially made disc, as well as a blank disc
6) shut down the machine again, unplugged the mouse and the power cable (had I used a wired keyboard, this too), and waited what seemed to be about 3 minutes; this was resetting the System Management Controller
7) plug the power cable an mouse back in, restart normally
Now I have to see just what device(s) might have contributed to the problem... I had a USB drive, a Firewire drive, and an older powered hub with which I attach my printer, EyeTV 250, a mouse, and occasionally, my iPods (shuffle & video) or thumb drives.

Portable drive no longer recognized

Hello.
I have an HP PD1000a drive that is no longer recognized by my HP 9040n (Windows 7 Ultimate) computer. This happened overnight. The drive can be recognized and the driver installed by another computer (HP laptop running W7 Ultimate).
When I plug the drive into the 9040, it is seen in the device panel but is disabled. When I try to enable the drive, Windows 7 is unable to do so.
Can you offer any assistance?
Lt. Touchdown

I have a similar problem. Apparently (for no understandable reason), it no longer works via a USB2.0 port, however if you have a USB3.0 port it will work via that. All attempts to contact HP to see if there is a fix have failed. They must be about the most disorganised, uncaring business in the world!

Optical Drive No Longer Recognized-- Yosemite, Mac

Like a fool, I updated to Yosemite. Now my external optical drive is no longer recognized and I can't burn a CD in iTunes. Please help! How can I get my computer to recognize my optical drive and burn a disc? I have a Mac Air.

Hi,
How is your optical drive connected? It may be a connection problem.
When you go to About this Mac, Overview, System Report, Disc Burning, what does it show?
Does the device show in the Finder window sidebar or in Disk Utility?

LaCie External Drive No Longer Recognized

My LaCie d2 Hard Drive (Extreme) suddenly is no longer recognized. This may or may not have anything to do with my copying several files to it just prior, with much memory still available on it. I rebooted my computer twice and it was still not there. Is this a crash? Should I kiss that drive goodbye? If not, any suggestions?

Bizarre. After some time it now appears, and apparently with all files on it. I thought the cable was already secure on both ends, but perhaps it appeared after tightening them just slightly. Do you think that was it?

IMac is no longer recognizing DVDs.

I have a mid-2010 21.5" iMac and my Superdrive is not recognizing DVDs. I have burned DVDs which work just fine. CDs work just fine and my DVDs are pristine, but the iMac spits them out continually. Repairing disc permissions worked temporarily, but the problem persists. What can I do?

Last night I read several threads on this topic. There is a lot iof information to digest and then decide what route works for you. You get to benefit from all my searching around!
My drive spits out my media as well, and because my iMac is out of warranty, I gave it a cleaning myself. I used a glasses wipe, the lint-free kind that comes with a glasses cleaning kit, some alcohol, and a very thin card (skinnier than a credit card) and inserted it into the drive. I read earlier that it was a mistake to use the compressed air, as it would only blow the existing dust & dirt further into the drive. When I pulled out the cloth, there was some dust residue. However, my drive, although i could hear it turning/operating better, still after a few moments, spit the CD and then a DVD out.
I ended up ordering an external drive off amazon for $30: a Samsung SE-208AB/TSBS External DVD-Writer and a high speed Belkin USB multi-port hub.
MacWorld addresses the issue pretty well:

Have you seen this response?!
Troubleshooting the slot-loading SuperDrive
http://support.apple.com/kb/HT2801
you can:
Reset the System Management Controller (SMC).
and zapping the PRAM
You can try resetting your SMC and pram/NVRAM but it's quite possible that your optical drive is failing.
Give this a try :
To reset the SMC
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
To reset PRAM/NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

T60 HDD res. partition, USB ports and DVD-RAM drive no longer recognizing data/media!

I have a base installation of the IBM T60.. I made no modifications to the setup or configuration of how the HDD is structured nor have I downloaded and installed any strange drivers... only automatically downloaded drivers from Microsoft update and manually downloaded driver updates from the Lenovo website.
One day everything was working fine. Next day, my USB devices, reserved partition (can't remember what this is called) and the DVD-RAM drive stopped working but power was still getting to these devices.
My DVD-RAM drive is seen as a DVD-RAM on first bootup. When I insert a CD or DVD media in the drive, the Explorer tree changes DVD-RAM to CD-ROM in the Explorer (really strange). It behaves like there is no media in the drive. Cannot boot with that drive either.
In addition, I have external USB HDD and Flash drives as well. None of them work on this T60 anymore.
When I plug in an external USB HDD or Flash drive, I get "not formatted" error message and a prompt to format my drives?!
I tested these USB external drives on a desktop machine and verified that they are working 100% fine. So the problem has something to do with my IBM/Lenovo T60.
It almost seems like something broke on the motherboard perhaps? I downloaded and installed the latest BIOS updates as well to no avail. Please help. Thanks in advance for your time and consideration of this issue.

MacBook DVD drive no longer recognizing blank DVDs

I thought I'd do some DVD archives of photos (using a Burn folder) and popped in a blank DVD (from a stack of blank DVDs that I've been using for a while).
Lo and behold this message popped up:
"The disc can’t be used because the disc drive is not supported (error code 0x80020025)"
I've done burning without problems on 10.5.x and this is the first time I've tried since upgrading to 10.6.
It seems to be a relatively common problem with no clear fix?

[solved] dvd drive no longer recognized

my dvd drive used to work. i was able to burn a cd just a couple weeks ago, not sure when exactly, but definitely no more than 3 weeks ago. today i pushed the eject button (just a keybinding mapped to `eject -T`) and i received an error saying
eject: unable to find or open device for: `sr0'
checked dmesg, there is no mention of an optical drive.
tried `modprobe sr_mod`, nothing new in dmesg, nothing at /dev/sr0.
i made sure the drive was connected and i was just able to boot off a cd, so it is connected and working.
anyone have an ideas?
