DVD drive "write protected"

When I insert a DVD-R into my external usb-connected Lenovo DVD Drive (USB 2.0 CD-RW/DVD-ROM Combo II Drive) and I try to format it to prepare it for backing up data, I get "Disk is write protected." What's going on?

you got the combo drive, and not a dvd burner, it can only burn cd and not dvd....

HP v165w 8GB formatting error - drive write protected - Windows can't format - HP tool can't format

Hi,
I am having trouble understanding what happened with this drive. It worked fine for weeks and weeks and now all of a sudden Windows 7 asks me that it needs to fix something because the files are corrupted or whatever... it does that successfully and after a few days I get an error message saying Windows can't access the drive and it needs to format it.
I did the following:
- Used Disk management with no luck... tried to format, reassign drive letters and so on.
- Used HP formatting tool - and this is where I get the message saying the drive is Write protected
- Used HP formatting tool and Disk management in Safe mode thinking there might be some processes running that are interfering, no luck, same result for both.
- Used AH320_Utility_LFormat with no luck... it can't even find the USB device.
One thing that catches my eye:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}
has the entry StorageVolumes - UpperFilters (tdrpman ; snapman ; timounter) - LowerFilters (fvevol; rdyboost)
Is it a registry issue? Like we see in CD/DVD drives when they go missing from my computer?
Is it a MasterBootRecord virus?
Is it a Windows corruption?
Please help! If you need additional info please ask!
Thank you!

DIAdem 9.1; Windows2000; right problem; "Configuration-Drive Write Protected" for USER

i run into problems working with DIAdem 9.1 on Windows 2000 SP4!
The Diadem installation went quite well.
My problem:
only "Administrator" and "Power User" have the privilige to "WRITE" to the DIAdem install directory.
Trying to start Diadem as non priviliged USER I get something like:
DIAdem Configuration-Drive "C:\PROGRAM FILES\ NATIONAL INSTRUMENT\DIADEM 9.10" WRITE PROTECTED!
I installed & started DIAdem for one
time with Administrator rights. I activated the Product and exported
the KEY to a License Server. Everything works fine for Power Users an
Administrators. Only "simple" USERs are not able to start Diadem due to
missing WRITE permissions. i can't grand this permissions to
normal USERs :-(
Playing around in Registry -> "RegWriteAccessAllow" ("0","1") (DWORD) (HKEY_LOCAL_MACHINE/Software/National Instruments/Diadem/9.10),
didn't solved the problem.
I switched back to "local License" Managment (local Key files) but the Probelm persists.
thanks in advance
P.S.

Hi DirkT,
Running DIAdem with User rights has different aspects we need to look at.
1) Registry Write Access
Launching DIAdem the first time with administrative rights registers some OLE components in the registry. After this step no more Admin rights are necessary for the registry. However running DIAdem as user might result in error messages as DIAdem tries to re-register the components again. You can avoid this by setting the RegWriteAccessAllow Key to 0 (see online help under "Administrator Notes")
2) File / Folder Write Access to the DIAdem Installation Folder
DIAdem needs write access to certain files e.g. the error logfile DEM_ERRS.001 or DESKTOP.DDD when saving configurations. You may change the folder where these file are being stored and searched for to a writeable folder by launching DIAdem with the "/d<NewFolder\MyDesktop.ddd>" start parameter or by setting the environment variable "DemDDD" to that folder. Then move the following files from the DIAdem installation folder to your new writeable folder:
*.ddd
userpar.par
dem_errs.*
3) File / Folder Write Access to other Folders
There are a number of other folders that DIAdem 9.x needs write access to and which cannot be changed. All of these folders are located by default under "%ProgramFiles%\National Instruments\Shared". Currently you need your Admin to give you write access to that folder and below
For future versions of DIAdem the team is working to make running under user rights easier.
Hope that helps,
Marcus

Thumb Drive write protected after plugging into MacBook Pro

So I recently plugged my 64GB thumb drive into my MacBook Pro to transfer music from my old mac to my new one. Although as soon as I plugged into the MacBook Pro, it write protected it rendering it useless as I do not wish to use it as a storage drive for 60 songs! It is not even 1/2 full and because I plugged it into a MacBook Pro I can't use it anymore!? It is formatted to MS-FAT, and previously I had plugged it into my 09 MacBook with no problems! Please help me Make it a read and write again!!! The thumb drive is only a week old!!! There are no virus' as I have had the music on my Mac for 5 years and it has all come from the iTunes store!!!

Choose Utilities from the Finder’s Go menu, open the Disk Utility, and try running the Repair Disk command on it. If that command’s not available or doesn’t work, copy your files off and try getting a replacement.

Lacie Drive write protected

Hi all,
I've purchased a new 500 gig LaCie drive and it is write protected and all the button pressing won't allow me to rename the drive. What I'm wanting to do is: I have a 250 Gig drive named after one of my clients. It's nearly full so I want to rename the new 500 gig drive the same as the smaller one then simply copy all the files from one to the other. Any advice would be much appreciated
Steve

Sounds like your drive is pre-formatted using the (PC) NTFS format ... you need to use OS X's /Applications/Utilities/Disk Utility app to reformat the disc ... format it as Mac OS Extended (not journaled) and you'll be good to go

Freecom CD/DVD Drive/Writer no longer recognised

I don't seem to be getting very far with Freecom's support so I thought I'd ask here. Since upgrading to OS 10.5.6 discs inserted into my external reader/writer are no longer mounting.
Has anybody found a solution for this?
If I open up Disk Utility and System Profiler it shows:

Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: To show the available burn speeds, insert a disc and choose View > Refresh

Many of us have had optical writers go unsupported w/Snow Leopard.
I'm back to relying on my internal burner, and with the very, very small number of discs I burn these days (like none), I'm not missing the external.

CD-DVD drive write problem

Hi Everyone,
I have a lenovo 3000 N200 0769. The operating system is Windows XP Pro. For some reason the CD/DVD RW drive can read files from cd and dvd but whenever I am trying to write on either one of these mediums, I always received a message asking to enter a blank writable disk while the drive already has a blank disk. Does this ring a bell for anyone? Your help is greatly appreciated.

Hi,
It would help if you identified your notebook with its complete product name or product number.
HP has produced and brought to market perhaps more than 10,000 models of notebooks and desktop PCs over the years. It is difficult to help you if we don't know which one you own and which operating system is installed.
Method #1: If the notebook will boot into Windows you can retrieve your Product Number by pressing Fn + Esc key. You can also read the Service Tag (if present) attached to the bottom of your notebook\netbook.
Method #2:
Remove the battery and look in the compartment where the battery was installed. You should see a printed part number and a product name. Please post one or both of them (with all alphanumeric characters here). If you live outside of North America, it helps us if you post the country of purchase.
Desktop PC
Look at the rear or side of your desktop for a service tag for the complete product name and product number.
Best regards,
erico

OS X Lion USB Flash Driver WRITE PROTECTED?

Read only.
In case if you have to reinstall the OS you have to use Software Update to update the system.

HP SimpleSave md1000h write protected! - can't initialize drive

The drive does not show up under windows explorer. Under Disk Management, the drive shows up as Not Initialized and Unallocated. When I try to initialize the drive I get "The media is write protected" Restarted the PC and also the external hard drive and the same thing.
I am running Windows 7 Professional 32 bit.

You need to be an admin and also go to Control Panel --> User Accounts and turn off UAC for your account. You can set the level back later.
When in Disk Management, did you right mouse click on the new drive and select initialize?
You might have bad hardware.

HP Pavillion dv6-3120us
OS
Windows 7, Home Premium. 64-bit.
Error Message
"Insert a Disc; Please insert a disc into E: drive."
Background
Pre-installed Windows 7 system on computer recognized CD/DVD ROM drive for about 3 months. Malware corrupted the OS. I re-installed the OS from the recovery drive's partition. CD/DVD ROM drive failed to read or write, and I cannot restore old files or back-up current configuration via CD/DVD ROM drive. All updates for Windows 7 and hardware drivers seem to be installed and up-to-date as of 10/4/2011.
Troubleshooting Steps
1. Tried to read audio CD. Same error message.
2. Tried to read data CD-ROM. Same error message.
3. Tried to read data DVD-ROM. Same error message.
4. Writing to DVD ROM failed. Same error message.
5. Re-loaded OS 2nd time. No change. Same error message.
6. Checked with HP Support Assistant. DVD drive is recognized, but not media. No change.
7. Checked Device Manager. DVD drive is recognized as TS-L633R.
8. Driver is cdrom.sys version 6.1.7600.16385. Clicked Update Driver, no change.
9. Tried uninstalling and re-installing the driver. No change.
10. Checked BIOS. AMD Turion II P540 Dual Core processor 2.4Ghz. BIOS appears to be up-to-date, version F.27.
11. BIOS lists CD/DVD ROM drive as bootable. Re-ordered drive to boot first and used Knoppix Linux boot disc, no change. Windows booted instead.
12. Reviewed registry for "upper filter" and "lower filter" entries. Checked registry 4D36E965-E325-11CE-BFC1-08002BE10318. No upper filter or lower filter entries present. No change.
13. Ran "Hardware and Devices Troubleshooter"; it cannot detect the cd/dvd. No change.
The drive has power, spins, is recognized by Windows 7 and the BIOS. However, it will not read or write CD ROM or DVD ROM discs.
I'm out of options. What else can I do to make the cd/dvd rom drive read and write cds?
Thanks for your help. Matt

Update:
I chatted online with Ben S. at HP tech support via the HP Support Assistant. Helpful guy. Thank you, Ben. He worked through it and his counterpart Alan is sending me a new DVD/CD drive. Ben S checked the following:
1. Confirmed that I had tried multiple discs to check different formats: DVD-R, CD-RW, audio CD, video DVD, software data CD. None were recognized.
2. CD/DVD icon appears in My Computer. Confirmed.
3. Checked Device Manager for yellow exclamation marks. None present.
4. Opened below Device Manager and checked for yellow exclamation marks. HP CDDVDW TS-L633R ATA device listed correctly. Redundant, but I understand; it's a good check.
5. Confimed the Model and Serial Number.
6. Asked whether I had done a System Recovery. I had. Twice. First time it didn't restore the drive, so I thought I'd try it again. Second time also did not restore the drive.
7. Ben S. concluded that the drive has a hardware malfunction, and offered drive replacement under warranty since I purchased in April. I should have it by Oct 17, and then I have 15 days to return the broken drive or I'm charged $80.
Alan offered an additional year of warranty service for about $100. Ben's guess on the root cause was a bad lens from stress on the DVD tray. I don't recall any stress events. I've had this laptop since April, 2011, and the drive failed at the end of September. 7 months. This surprised me considering I've got other notebook computers with drives that have lasted years and still haven't failed.
I'll check in when I get the replacement drive.

DVD drive stopped writting DVD's on my Satellite 5200-801

Quick question that I hope someone knows the answer to. My DVD drive stopped writting DVD's a while ago (several system reinstalls have proved that it is the drive and not a driver error/conflict) So I got hold of another drive. Fitting was easy however it appears that there is something funny with the ide chain configuration in this laptop. The old drive was set on cable select, however the new drive is set as slave. because of this neither the HD or the DVD drive are accessable.
Does anyone know how to switch dvd drives to cable select to make them work (I tried putting jumpers on the HD to change it between a master and slave but with no joy.)
Thanks in advance

Hi John,
Normally, slim design CD/DVD drives are preset by the manufacturer but it is apparently possible to change the setting if you really want to. Please check out the following post :-

By internal, I assume you're referring to your systems (boot) drive. Is it, by chance, a partitioned dive?
Also…although many people successfully use their systems drives as scratch disks, over time you'll have better results using a dedicated drive for your media.
Good luck.
