Windows 7 - corrupted data on external dvd usb device

I have problem with my external brand new usb dvd drive (liteon 124 sata + welland 340Q). Its connected to HP Pavilion DV9220US by usb port. The problem is that i can write discs without any problems but there is huge problem with reading data form cds (even from older one recorded before i installed windows 7) :/ . I see all files and folders on disc but all data is corrupted. I can't open any large file. Small files like txt open just ok. Some photos on my cds are broken. Video files are corrupted. On other computers with different OS there is no problem with reading any of that discs (writen on windows 7). I'm going crazy. Something is wrong with reading files from usb external drives. There must be something wrong with windows 7 :/ My notebook doesn't have any nvidia chipset so update KB976972 is not for me. I hope microsoft will fix that issue soon. I even bought express card 54mm usb controller but that doesn't help too.
I have tried many intel chipset drivers and uninstallation of all Universal Serial Bus Controllers in device manager but it doesn't help too.
I also checked on my friend notebook with windows 7 and there was the same problem :/. Later he installed windows vista and everything start to work perfect.

Hi akslow,
It is highly recommended contacting the device manufacturer first to confirm whether the DVD drives are fully compatible with Windows 7.
Also, please access Clean Boot to check the issue. If the issue disappears in the Clean Boot environment, we continue to narrow down which entry is causing the issue. Besides, you can copy the files to the local hard drive to see if they can be read.
If the issue persists, could you please capture some screenshots of the error message when trying to read the files?
1. Please reproduce this issue, and then press the Print Screen key (PrtScn) on your keyboard.
2. Click the "Start" menu, type "mspaint" in the Search Bar and Press Enter.
3. In the Paint program, click the "Edit" menu, click "Paste", click the "File" menu, and click "Save".
4. The "Save As" dialogue box will appear. Type a file name in the "File name:" box, for example: "screenshot".
5. Make sure "JPEG (*.JPG;*.JPEG;*.JPE;*.JFIF)" is selected in the "Save as type" box, click "Desktop" on the left pane and then click "Save".
6. Please upload the screenshot to your SkyDrive at www.skydrive.live.com and let us know the link.
For detailed steps on how to upload files with SkyDrive, please refer to:

Have a canon dc310 camcorder that uses mini dvd's. How can I get my new Imac to read these dvd's?Camcorder unable to connect to computer. Will a mini dvd adapter work or do I need to purchase an external dvd rom device? Which device works well with a mac?

I have a Canon DC310 camcorder that uses mini dvd's and doesn't have the ability to connect to a computer. How can I get my new Imac to read these dvd's? Will the mini dvd adapter work or do I need to purchase an external dvd rom device? Which device works well with the Mac? Do I need anything else to get the dvd material onto my mac? Thanks!!

No DV port in camcorder. Just a yellow AV port/hole. I did find a Canopus ADVC110 device in a box that was bought several years ago to convert VHS tapes onto DVD's. Can I use this with a Mac? Could I connect a dvd player to the Canopus and transfer the disks onto my Mac? Or, connect the camcorder via AV port to the Canopus and that to the Mac and transfer that way? Thanks again!

This would imply that the Windows CD you have may be the problem. Have you tried this disk on another computer. (Boot the other computer with the CD, but cancel the install before it format's your hard drive.) Did this CD come with another computer? Many of those "restore disks" are not bootable and can't be used for other computers. You usually need a retail or volume license copy of Windows. (For legal reasons as well, but we won't get into that now. )
The disk is good and I teste it on another computer and I've burned another CD from my original .iso
It's a standard Windowx XP Pro disck, no upgrade, and I tried with a standard Windowx 7 Home Edition 64Bit and 32Bit, both standard version not upgrade or restore disk
And I donw' want install only windows, I want Snow Leo as primary and a small bootcamp for windows.
Which is why you definitely want to go through Boot Camp Assistant otherwise you risk loosing the Snow Leopard partition.
I know, I've just some year of IT system, but thank's for warning
No, when you are in target mode you can use DVD too, you can try it
Ok, good to know.
Just to summarize my try:
- Standard SATA DVD-RW drive (5" 1/4) connected by SATA->USB
- Standard SATA DVD-RW drive (5" 1/4) connected by SATA->FireWare 400/800
- Samsung external usb DVD-RW drive - http://tinyurl.com/y8vhu29
- USB Flash drive with Windows XP or Windows 7 install software (it goes really well with standard pc)
- Another Mac in Target Mode as DVD reader
- rEFIt - http://refit.sourceforge.net/
I tried it with Windows XP, Windows 7, Ubuntu and Snow Leopard install disk, the only one that goes with ALL methods is Snow Leopard.
From rEFIt website, I found that Mac cannot boot Windows or Linux from an external disk is not well-supported by Apple’s firmware, and for external disk it mean any storage device that is not considered "internal"*, that includes USB Flash drives, SD cards, USB/FireWare DVD/HardDrive, but that is not true for MacBook Air, that it maybe have an EFI firmware without that limitation because haven't an internal drive and because MBA it's the only Mac that can use MBA SuperDrive USB.

I cannot mount a external DVD usb drive

Hello,
I am trying to install a extenal DVD usb in a sparc enterprise t5220 with Solaris 10. After connecting the device i got this message:
WARNING: Device /pci@0/pci@0/pci@1/pci@0/pci@1/pci@0/usb@0,2/hub@4/cdrom@2/disk@0,0 failed to power up.
WARNING: /pci@0/pci@0/pci@1/pci@0/pci@1/pci@0/usb@0,2/hub@4/cdrom@2/disk@0,0 (sd3):
Command failed to complete...Device is gone
I rebooted the server and used different ports but i still got the same message several times.
Is there some one that can tell me if this is a hardware problem or is there any procedure to install and/or mount this external device?
Thanks

USB drives can not be used to boot a PowerPC Mac so you will not be able to install new OS X; recover in the event of a major problem or repair the hard disk if it become corrupt to name a few examples if you purchase a USB drive.
Firewire performance on the Mac is also far superior to USB2.0 performance.

Installing Windows XP on Lion using external DVD drive

Hi, this is my first time posting on a forum at all, so just keep that in mind when dealing with me.
I have recently attempted to install Windows XP by partitioning my drive using the disk utility (seeing as Bootcamp no longer supports Windows XP installations). The problems start when I boot from the installation disk; an error "no bootable device - insert boot disk and press any key" occurs. I am inclined to believe that this is due to me using an external DVD drive when doing all of this. I am using an external DVD drive because my internal DVD drive has been spoilt and is no longer useable.
Does anyone have a solution for me? It seems that it is not possible to install windows using an external DVD drive.

I am doing this after doing a full wipe of my hard drive and reinstalling lion.
Previously, I had lion, and made a partition using disk utility and booted from the disk (this time it was from my Mac's SuperDrive which was functioning perfectly at this point in time) and finished the installation completely fine. I then used the drivers that were in my Snow Leopard DVD (I have a Snow Leopard DVD from a previous Mac I purchased).
The only difference between then and now is that I am using an external DVD drive.

Installing Windows 7 on Parallels with external DVD Drive

Hi. I have a Mac Mini, and just finished installing Parallels 8. I am now trying to install Windows 7, but they system is not recognizing my external DVD drive. I get a message telling me to install from an image file? Not sure what that means. Help! Thx.

Why can't I boot from my windows install disk using an external dvd drive?

My internal disk drive is broken on my computer, so I'm using an external one, but when I put my windows install disk in, it shows up when I'm using the computer, but it doesn't show up when I hold ALT on startup. Why is this?

Alt/Option Boot code is all in ROM. It shows an Icon for each potentially-bootable Volume.
Your Windows install DVD is not directly bootable, and so it does not show an Icon. (An OS 9 Installer CD would not show an Icon either.)
To install Windows, you need to research the use of Boot Camp, the software that provides Mac drivers and facilitates the Installation of Windows on a Mac. There are also Windows restrictions on the use of external drives which you may have to meet.

Yoga 2 Windows 8.1 - Cannot use external DVD Writer

I have bought a plug and play LITEON DVD Writer. Nothing happens when I connect it to the Yoga. It works fine on an ASUS laptop so it must be something on the Yoga.
On the Yoga it lights up but does not appear on the Drives.
If I look in Settings it appears on OTHER DEVICES as
MASS STORAGE DEVICE - Driver Error
I know there is nothing wrong with the LITEON
The USB ports work fine on the YOGA
Thanks
Richard

The power is fine as the drive works on other PC's. We tried other drives on this PC and still didn't work.
I am no expert but my IT dept at work tried to explain that the Driver is corrupt but part of the operating system. Not possible to update or reinstall.
I called John Lewis. They immediately said no problem. We will swap it for a new one.

Combo Drive reading Dual Layer / booting from external DVD USB

I am helping a friend with an iMac G5. He has the combo drive which is not able to read the dual layer Leopard DVD. I have looked to see if there is a firmware update for the drive however no luck. I am able to put an external usb DVD and it reads the disk however I was not able to boot from the disk using keyboard commands I tried AppleOption+ShiftDelete, C, and also tried Option but no luck.
I have been reading that booting from usb external drive is a no no on older G5 iMac's unless you are using fire wire. If any one can give me some help with getting the USB drive to boot, or figuring out why the combo drive spits out the DVD every time I would appreciate it. I am also willing to make a bootable usb leopard thumb drive, but I don't want to waste my time if it's not going to boot from USB.
Thanks,
jtadmin

Do you happen to have a more recent Mac that can read the Leopard installation DVD?
If so, you may be able to start up your Mac in FireWire Target Disk Mode,
http://support.apple.com/kb/HT1661
and let the iMac G5 use your Mac's optical drive to boot from the Leopard DVD.
Also, it is true that PowerPC Macs can generally only boot from external drives that are FireWire.

Need to get an external DVD player for Imac, which one?

Hey (again),
I've had a terrible time getting my imac up and running properly since I got it back from its HD replacement yesterday.
It's gotten to the point where I'm going to wipe the system and then do a time machine reinstall.
My problem is that my imacs dvd player doesn't play DVD's anymore, it just spits out the install DVD. Could I use any cheap external DVD (usb) drive and wipe and install my OS from there or does it need to be in the internal one? I found a couple of really cheap ones that I'm wondering would do the trick or does it need to be a specific brand?
Or do I need to have my imac which is out of warranty serviced and have the original dvd player replaced?
Any input on this is greatly appreciated.

In my experience just about any external DVD drive works. I've found them way cheaper at a big technology store like "Fry's".

After paying for a new MacBook Air, I still have to purchase an external DVD Player? That *****!, After paying for a new MacBook Air, I still have to purchase an external DVD Player? That *****!

I am confused about the new MacBook Air. It would appear it does not have an internal DVD/CD drive as most computers do. Does this mean after the price of this Mac Air I still would have to purchase an external DVD/CD player to load software or play DVD's and CD's ??? That seems like technology is going backwards and the owners just want more money. If I am wrong, I applogize.
Thanks,

Floppy drive? Who has floppy drives in this day and age. Does anyone sell software on that format? I don't think so. At least any software sold today.
I've had my MBA for nearly 6 months now and don't miss having a built-in DVD drive in the least. First of all, with only a 128GB drive, I'm not "porking" it up with a lot of junk.
The form factor of the MBA is beautiful and wouldn't be possible with a internal DVD drive. I wouldn't want one anyway. The only time I've use an external DVD USB drive was to install a few programs that I have on DVDs.
The MBA is about a very light weight computer for use mainly outside of the home. And this is where it excels. If you really want a DVD, get the Apple unit for $79 or a no-namer on ebay for around $25. Then use it and park it. You won't need it very often if ever after the first use or so.

Apple IPod USB Device Driver Not Installed? WIndows not reconizing IPod!

Hoping someone can help me with my new Ipod Nano. I installed the IPod Updater and Itunes programs from the provided CD and formatted the Ipod. That all works fine -- the Ipod actually works, etc.
But during the actuall instation process, the Hardware Update Window came up for the 'Apple IPod USB Device' (I use Windows XP) I've tried to have it install automaticaly and manualy, without any luck. As a result, when the IPod is connected to the computer, I get a '!' on the device in Windows Explorer and neither ITunes or the Ipod Updater -- or Windows -- will reconize it!
If I connect my Ipod to the computer, the 'hardware' icon comes up in my system tray and the Ipod screen changes to the 'Do not disconnect' message. I can click on the hardware icon to 'remove' it. But I can't DO anything with the Ipod if nothing will reconize it!
I've tried updating the ITunes and Updater to the latest versions, plugged the USB cable into different spots on my computer, uninstalled and reinstalled everything, this time selecting the 'do not connect the Ipod to the computer at this time' option.....nothing. Windows just will NOT reconize the IPod and everytime I install the software I get that Hardware Update Window screen up!
Is there a driver for this I'm missing somewhere? What's going on? I can't do anything with my IPod and can't even find a phone number to call Apple for help!

1-800-275-2273.
This might be an issue with your operating system. You might also want to try using it on another computer before calling them as they'll probably ask you to do so. This will isolate the problem to your computer and they might tell you to try calling Windows or getting the latest drivers for your computer.

Booting From An External DVD Burner

Hi,
My Parents' Leopard copy will arrive in a few days, and since the iMac G5's drive is dead, I was wondering if the install process will be possible from an external DVD drive device.
PS: I also have an iPod 30 gig (if it's impossible via the DVD drive, is it possible via the iPod?)

IMPORTANT: is it normal that when I boot from the external Drive (Firewire) the grey screen with the Apple (start up screen) remains static for a long time? (the loading "flower" doesn't show up) .
I need a reply please, because keeping the Mac on that start up screen would be stupid... if it's useless.
Thanks

USB Device Not Recognized

Operating system: Windows Vista
Error: USB Device not recognized
While actively on the computer, we suddenly got a message stating that the USB Device was not recognized. The only thing plugged in to the USB port was a mouse. Tried all the ports, same message. Tried another mouse, same thing. Tried a thumb drive, and low and behold, 2 of the 3 USB ports worked. Tried a URL from MS which is supposed to help with this exact problem and possibly fix it: http://windows.microsoft.com/en-us/windows-vista/Tips-for-solving-problems-with-USB-devices
This didn't work.
Contacted HP support and they wanted me to restore back to a restore point as well as updating my BIOS. After searching the issue more extensively using Google, I found that several people said to do this:
Shut down the computer
Remove the power plug
Remove the battery
Put the battery back in
Power up the computer (without the power plug)
This forces a hard reset.
Almost as if by magic, the problem disappeared. A much simpler and less technical solution to the problem than what HP recommended!!!!
