Restore win 7 from system image on toshiba portage m200


This should apply to other brands and models...
the original problem: bad hard disk, need to restore from win 7 image disks however The portage m200 lacks an optical drive and cannot be booted from usb (only options are to boot from LAN or from a specially created SD card).

Solution:
you will need a second pc that can boot from an on board or peripheral optical drive. Swap the second pc's hard drive for the one that you are restoring. Now boot the second pc from the restore disk and follow the onscreen instructions. Once completed the pc will try to reboot and you will get an error about how windows couldn't repair start-up. Now power down and swap the hard drive back to the portage. You should now be up and running, much easier than trying to create a boot-able sd image or boot from a PXE server.

DVD/CD-RW drive not reading dvd disks, but plays audio disk fine. when i put the dvd disk in, i hear it spinning for a little while as if it is trying to detect it then stops. when i look in my computer...


They look the same, but CDs and DVDs are two different media, and a combination drive essentially has two separate optical systems in one package. What sometimes happens is that the laser that reads and writes one kind of disc stops working, while the other format isn't affected. If the DVD problem is happening on every disc you try, the failure is complete. Sometimes in its early stages some discs read fine but others don't. Sometimes the problem may occur on dual-layer DVDs only but not single-layer ones. In any case, there's no way to repair the drive other than by replacing it. You can find replacements online for most laptops, but they can be expensive. If you don't mind carrying an extra piece in your computer case, you can get a USB external drive and just leave the bad one in place.

I have a desktop and i was told that i can use a portable super multi drive burn on my computer. ok but it says its for a mini notebook users. i already use it to burn music but it dont let me use it to...


Optical drives vary in their capability:
* read CD
* read CD and read DVD
* read/write CD
* read/write CD and read DVD
* read/write CD and read/write DVD

What capabilities are available on your "Super Multi" drive?

What software are you using to try to create/burn CD/DVD disks?

DVD-RW drive does not read disks


the DVD-RW is faulty, take it in and get another one to replace it. the clicking noise may be coming from the rack gear inside the device and causing a malfunction.

DVD Drive reads CD's but wont read any DVD's


Hello,

Let me explain some things for you to understand what happened with the dvd drive.

A laptop (or desktop) dvd writter drive is actually build around 2 separate optical systems each specialised to deal with either a cd or a dvd type of disk.
A cd has normally around 650mb - 700mb.
A dvd has normally around 4,3gb - 4,7 gb.

But both disks have the sime size. So the larger capacity disk, the dvd has higher data density as related to the disk surface. Therefore because these disks are being read using laser diodes, each diode must be tuned to a specific frequency for each type of disk. A cd is read/written by a 860 nm diode (infrared) and a dvd is read written by a 630 nm diode (red). These are separate optic subcomponents (by the way, a blue ray disk and reader is called blue ray because of the diode that is used to read them, it's on 437nm and it's emitting blue light).
If your drive will read only cd's and fail to read a dvd then it means that the coresponding optic block for dvd reading has failed. The cd optic system will continue to function as it's not linked to the dvd part.
In this situations there is little to do to save your drive so you should consider the replacement or assistance in a service center for your problem. I'm sorry as we aren't able to fix this without having to dissasemble things and use some service equipment.

My toshiba sd m1612 doesn't play about hapf my DVD's


Nitzan,

OK... sounds like dirty Laser Optics to me...

There are CD CLEANER disks that look like a regular CD, BUT on the bottom there is a tiny (real) "brushes" that cleans the dust and dirt away from many/most CD/DVD devices!

I don't recommend that you use it too often because you do not want to SCRATCH your Laser Optics with dust or dirt... you just want to clean the laser face...

Reinstallation with recovery disk


I've had myself almost same problem in my 5200-801, but with reading DVD's.
It was allready the second dvd/cd drive replaced by Toshiba.
Then I replaced the DVD/CD drive myself because I ran out of guarantee, with one bought from the internet and much cheaper than the original one. A multi drive which even do the lightscribe job and that one works very well.
