CD drive of Satellite Pro A200 is not digitally signed?

Question: CD drive of Satellite Pro A200 is not digitally signed?

I cannot use the CD drive on my Laptop, the device manager shows the a yellow triangle with an exclamation mark in it. I have updated the driver but it still wont load and I get the following message from the device manager: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39).

Any suggestions as to how to fix the problem?

Preferred Solution: CD drive of Satellite Pro A200 is not digitally signed?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: CD drive of Satellite Pro A200 is not digitally signed?

Did you tried to remove the drive in the device manager?? That helps sometimes, because windows reinstalls in the most cases the previously removed (deleted) hardware.

Since when does the problem occur that your drive cannot be recognized?

I'm looking at my DirectX Diagnostic tool and it says for a few things
"The file ati2dvag.dll is not digitally signed" under Video, and "The file RtkHDAud.sys is not digitally signed" under sound 1 and 2. is this a serious problem? it might help solve why I've had a few crashes when playing games maybe? If anyone can help I will be very grateful, especially by telling me how to get these "signed"

My stats are

Answer:Not Digitally signed?

I know very little about this kind of stuff but I think it just means it's a driver that hasn't been registered with Microsoft, or something along those lines. I don't believe it affects the operation of the thing.

I have had to reinstall Windows 7 64-bit edition, and when I go to install PCWizard or Everest Home Edition, I keep getting an error about drivers not being digitally signed, and Windows will not install them. Before I reinstalled Windows 7, I had both of these programs running just fine. Is there anyway I can change the fact that Windows 7 will let me install those drivers?

Answer:Digitally Signed Drivers?

The only way for 64 bit versions of Vista or Win7 to work without digitally signed drivers is to start them up using F8 to get teh Advanced Startup and disable the Digitally Signed Driver service.

If you had them working before did you make sure all your drivers now are current?

Dear All,
A vendor website sporadically release's MSI's which are digitally signed (plugins to run the content). These are required for the website to function.
Users are more in number so we can't manually install the MSI and time is a constraint.
Packaging / Repackaging is not a quick solution
App-locker doesn't bypass UAC, AUTO IT didn't help, Manifest and shim are only for Exe's.
We are looking for a solution where in since these are digitally signed MSI's Users should be able to install them automatically without being asked for the credentials.

Am trying to install HP Deskjet 630c printer and it keeps telling me this driver is not digitally signed. I just put Windows xp on the computer. What does this mean and can I get help? I am not very computer literate and any help would greatly appreciated. Many thanks Paula.

Answer:driver is not digitally signed

"Not digitally signed" means Microsoft have not tested this driver and verified it to be compatible with Win XP.  This does not mean it will not work, you should click on the "continue anyway" to install your print driver.  If this is a concern you should check the HP web site for newer driver tested by MS.Kim

Hi Guys, I did a search of my OS, and found some Drivers not digitally signed.Is that a problem,as my PC is functioning OK.Thanks for any advice.

Answer:Digitally Signed Drivers.

Hi D,
Your ok for the most part. A driver that lacks a valid digital signature, or that was altered after it was signed, can't be installed on x64-based versions of Windows. As a result, you will see this message ( Windows cannot install this driver ) if you are running an x64-based version of Windows.

The only other time (I think) may be if you updat a driver. again you may get that can't install it error. You can visit the device manufacturer's support website to obtain a digitally signed driver for your device.

So I just upgrade to Vista x64 and 4GB of memory (courtesy of OCZ).

However, when installing the x64 version of MagicDisc/MagicISO I get the following error:

Can I get around this?

Answer:Required Digitally Signed Driver?

Uhmmm... yes, you can by pressing F8 at boot time and choosing to ignore the warnings about unsigned drivers, but you have to do it each and every time you boot. There is a way to permanently disable that driver signing requirement but I'm leery to give out the info anymore since it hosed a few people's machines recently.

It wasn't my fault that they chose to continue using shitty old drivers, but they blamed me for the mistake they made anyway.

Vista x64 is a more secure and stable OS than the 32 bit version, and that's one of the primary reasons why: the driver signing requirement. Disabling it or 'getting around it' will more than likely end up causing you issues at some point.

Google can find the specific method to disable the signing requirement permanently, or a search here might find it since it's been posted about 3 times over the past 4 months or so.

Good luck, either way...

Answer:Windows Drivers Digitally Signed

The fact that the drivers are not certified by Microsoft merely means that the vendor did not submit them for testing and pay the bill to do so.

Many perfectly good drivers are not certified -- so do not worry about that unless you actually have problems with the hardware.

Having said that there are two ways you can restore the old drivers in XP. One is to go to the Device in question in the Device Manager, open its properties dialog (double click it) and select "rollback driver" on the driver tab. Windows XP backs these up automatically when you make a change.

The second is to use System Restore to return to a prior date.

G'day. I'm trying to install my old VisionPLus DVB-T card into a Windows 7 O/S box and it won't recognise any of the old drivers. When I try to install the TwinHan Digital tv software, Windows can't/ won't install them.

When installing the above, it identifies my card as “PCI CX-87A with MCU DVB-S/-C/-T/ATSC card”.

When the computer boots up the new hardware wizard comes up asking for a driver for a realtek AC97 Audio device. I have tried everything I can to install the driver but each time I try I get an error that the driver is not digitally signed and it won't install. If I try in safe mode it installs but I get a blue screen upon startup and have to reboot.

Hi all, hoping this is the right subforum

I built a HTPC a few years ago and it had suited my needs fine. Relevant parts used are:
i3-3225 CPU,Scythe Big Shuriken 2 RevB,Asus P8-H77 Pro,2 x 4GB G.Skill Ares DDR3 1600 RAM,Samsung 830 Series 64Gb SSD (OS HDD),WD Cavier Green 2TB (Media HDD),

I tried to upgrade to Windows 10 but kept receiving errors, such as the partition was not GPT (0xc000021a). The one error that happens every time I tried to upgrade or install Windows 10 was winload.exe was not digitally signed. I wiped the drive, reformatted it as NTFS, converted to GPT and installed W10 from blank and still had the same winload.exe error. Right now I have put W7 Ultimate 64bit back on and am installing all the windows updates.

My question is, does anyone know why I keep get a winload.exe not digitally signed error? I have downloaded the W10 upgrade files numerous times, redownloaded the media creation tool, set clean boot, even tried downloading the upgrade and creating a usb drive with it from a different PC but same error.

Is there perhaps some upgrades that I should make my HTPC?

From what I know if these progams are running and they aren't digitally signed then they are most likely a form of a virus. I can manually find the official conhost.exe from windows/system32 and run it, that creates a separate instance of it running, making two, the official and the supposed virus. Neither of the supposed virus executables do not open any properties when I right click and select properties from the task manager, which is another red flag. I ran a fully updated malwarebytes scan and an avast scan outside of windows and had no returns of an infection. I could not find the location of the virus executables and I am looking for some help.

Hello everyone,

So I click "Load Drivers" and select the x64 raid driver I got from MSI. It shows up, then I click next and then the error message comes up: "To continue installation, use the Load Driver option to install 32-bit and signed 64-bit drivers....etc"

I restarted and spammed f8 to get into advance startup options. I selected "Disable digital driver signing"

However that did not fix the problem.

Answer:[SOLVED] System Files Not Digitally Signed

Hi TomGab and welcome to TSf !

You don't have to worry about system files that are not digitally signed, it only means microsoft hasn't run extensive tests on them. The file owner (nvidia for most of your nvxxx.dll files for instance) will have tested them to make sure they would work fine with XP so you shouldn't have any problem.

Why is everyone saying Vista 64-bit won't install unsigned drivers? I installed the latest beta driver from nvidia and Vista warned that it was unsigned but gave me an option to install anyway.

Am I missing something/misinterpretting this or was this only the case in the Beta/RC verisons of Vista and everyone keeps bringing it up (kind of like requiring UAC for changing backgrounds; people still say Vista does it)?

Answer:Digitally signed drivers required under Vista 64-bit?

Short answer: The effects of FUD.

Long answer: The truth is, it was never stated on any official documents that Vista wouldn't accept unsigned drivers. The real mechanism is how Vista handles such drivers, in that the permission level changes, but that's such a 'behind the scenes' object that some ppl though it cooler to just say, "NOEZ, the sky is falling!".

Answer:windows require a digitally signed driver xp 32 sp2

A signed driver is not necessary in Windows. It is an extra security layer, as drivers can become corrupt by malware. If you obtained the driver from a trusted source (like the device manufacturer's website), you can go ahead and tell Windows to install it.

I recently purchased a new pc that came with win vista 64 bit premium home installed. I am now reloading all my old programs and I keep getting ?windows requires a digitally signed driver" error message. I also can't seem to play my old movie files, all of which played fine when I had Win XP. Apparently Vista does not want me to make my own decisions, so I am wondering how I might go about disabling all this extra secure vista crap. Can I go into Control panel and disable the BitLocker Drive Encryption? Or do I need uninstall 64bit and install the Vista 32 bit? Would that be a smooth transition? Would all my stuff work again if I had the less securitized 32bit Vista? Thanks for any help you may provide.

Answer:windows requires digitally signed driver

Welcome to the Vista forums

1) You don't want to disable UAC (User Account Control) as it does a lot to protect your computer from various malware. If you really feel the urge to turn it off, then you can in control panel in the User Account section. Once turned off, you'll get the red shield in the bottom right saying it's disabled. Disable security warnings by opening security centre and going to "change how security centre warns me" or something and choose the "no warnings" option.

2) Just download the Vista codec pack (just Google it and you should find it) and DivX and you should have no problems watching videos.

3) You can install unsigned drivers on Vista 64 bit, do this by running an elevated command prompt (right click on command prompt in Start menu and click "run as administrator".

Type this and press enter bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

When you reboot, you should be able to install unsigned drivers.
Also, I looked on the HP website for your computer, and it has 6GB RAM, so going to Vista 32bit would only allow you to use about 3.5GB RAM. I also saw it only has an Nvidia 6150e onboard graphic card. Are you using this? As if you upgraded this to a graphic card, you'd notice better performance on Vista as well.

I'm trying to install a program, but I says I can't install an unsigned driver.

Driver: CPU Core Temperature Monitor
Service: Logitech CPU Core Tempurature (not a typo)

I've tried Disable Driver Signature Enforcement in my bios, and DDISABLE_INTEGRITY_CHECKS in cmd.

Neither works.

Answer:Need to bypass digitally signed driver requirement.

Go to Start Menu > Run and type the following command: bcdedit /set nointegritychecks ON
Restart the PC and install the unsigned driver
After installation go to Start Menu > Run and type the following command: bcdedit /set nointegritychecks OFF
Restart your PC

The last few times I started my computer, the system comes with the warning:

"Windows requires a digitally signed driver
Driver: Broadcom NetDetect Driver
Service: BASFND
Publisher: Broadcom Corporation
Location: C:\Program Files\Bra...\BASFND.sys"

Windows suggests to uninstall the program or device that uses this driver and check the publishers support site to get a digitally signed driver.

The problem is that I have no idea of which program or hardware is using this driver. All the drivers I have installed in my computer are from the computer manufacturer.
I have also been at Broadcoms homepage and there is plenty of things to download there. But I dont want to ruin anything.

Suggestions on what to do?

System: Windows Vista 64

Answer:Windows requires a digitally signed driver

Broadcom is your onboard ethernet, I don't see why it would suddenly complain unless there was an update.:confused You can disable driver signing but it only cures the symptom and not the cause.

Windows Vista x64 decided to implement a 'security measure' by which all drivers must be 'digitally signed' to be allowed to install and run. I have a program which is compatible with Vista and x64 bit operating systems, however as its drivers are not digitally signed I cannot run it correctly - I recieve the message 'Windows requires a digitally signed driver' and access to the driver is blocked.

Is there a method of bypassing this?

When you boot your system hit F8 and you can bypass it there. You will have to do this every boot. There are a couple applications out there that will do this for you but the names escape me right now.

I'm at my wits end. Anyone who can help would be my hero.

Acer 5253 laptop, Win7 Home Premium 64bit SP1, AMD C-50.

Trying to use a USB mouse. I have 3 logitech mice. None work because hidclass.sys and hidusb.sys are not digitally signed. If I f8 and disable driver signing enforcement, all 3 mice work, so I'm pretty certain that's the issue.

Logitech does not furnish drivers for Win7. They rely on the native drivers.

Acer does not furnish mouse drivers. They refer you to the manufacturer of the mouse.

Tried copying the files in question from a 64bit machine that showed them to be digitally signed. Renamed the ones on my machine and pasted the ones from the "good" machine. Resolved nothing.

Hello everyone!

Could someone explain me what to do in order to connect a second HDD in the secondary slot of this laptop?

I've opened the lid but there is no socket or connector for install one.

For what I see, seems that I have to buy some additional piece, but I've no idea of what.
The manual is telling that there is this bay (hence it's usable since Toshiba bother to write it's presence in the manual).

Can someone help me???

I would really prefer it for practical reason to an external HDD even if will reduce the laptop autonomy when on battery.

Thank you!!!!

Answer:Satellite A200 UH1 - 2nd bay hard drive

If you want to connect a second HDD in this slot there must be a connector and if you don?t have one you can?t put in a second HDD.
Not every Satellite A200 has such a connector.
About this second HDD slot I founded the following information in user manual:
>HDD2: ? The availability of this feature depends on the model you purchased

But you can use a second HDD in the slot of the CD/DVD drive. For this you can use a bay for a second HDD.

In Device Manager when I click on DVD/CD Rom drives, I get TSSTcorp CD/DVDW TS-L632D ATA Device.

I have not tried to burn a DVD.
I have run through all the steps for burning a CD, however, but even though it goes through the process of showing the progress as each song from a playlist is burned to disc, when the disc is supposedly finalized...there is nothing on the disc when I try to play it back and with the exception of iTunes or another program opening when I place the CD into the drive to be played, absolutely nothing happens.

Answer:Satellite A200-AH5 CD/DVD drive does not burn any CDs


In your case I would recommend trying different CD?s from different manufacturers.
You should know that not all CDs or DVDs would be fully compatible with your internal CD/DVD drive.
In many cases not compatible CD or DVD would cause exactly the same issues which you have described in your message? so try different medias!

Furthermore I would recommend checking the Toshiba driver page for an CD/DVD drive?s firmware update.
As I?m not mistaken the Satellite A200-AH3 belongs to the Canadian series and you should check the Canadian page for some new firmware. Maybe a new firmware is available?

Last but not least you could switch to other burning software? I?m using the Nero? In my opinion it?s the best applications for such purposes

These drives are known to have issues with conflicts etc... so a different drive would be better.

Answer:Satellite A200-195: What CD/DVD drive is compatible?


Thank you very much that you are seeing us as experts :)
We all here are Toshiba notebook users and as you probably don?t know this is a user-to-user forum. :) so maybe not really experts ;)

To be honest it?s not known to me that this CD/DVD drive causes issue.
As you probably don?t know every CD/DVD drive doesn?t support all possible CD?s or DVDs from different manufacturers.
Some CDs and DVDs are more compatible and some CD?s or DVD?s are not fully compatible.

However, the point is that you need a new CD/DVD drive.
I checked the A200 user manual (can be downloaded from the Toshiba page) and there is a list with some compatible drives.
Check the user manual page 6 and 7

Have you tried using other brands of discs? Some of the cheap ones use a dye that doesn't last long and can cause burn errors.

You could also try removing the upperfilters and lowerfilters from the registry. This tool can do it for you:

What is your Internet setup? Do you use Wifi? An ADSL modem? 3G?

You can buy and install WinXP from Microsoft, you just need the SATA Driver on a Floppy Disk during installation. (search the forum for "f6flpy" for instructions)

I observed that if the disk was in the unit before the operating system started the unit was reading the disk. If I open the dvd unit and I close the unit (with the same disk inside) I have the message to insert a disk into drive and the message remained until I restart the operating system.

I have tried to recover the operating system with the DVD it came to but after install I had the same problem. I have tried with another operating system , windows XP , with all drivers installed (BIOS inclusive) and the problem still remains. The notebook works very fine except the dvd drive.

Answer:DVD drive is not working on Satellite A200-1S5


one suggestion which could avoid to send the machine to a repair center would be to check the Toshiba Drivers Download site for a "firmware" upgrade for your drive. If no one is available or the firmware does not help to resolve the problem then you should definitively send the machine to an authorised service partner since it could really be a hardware failure.

If you need a link to find the nearest service partner in your country then you should click [HERE| 000000871] and phone an ASP for a hardware chckup/repair which is nearest to you.

> Do these drivers work with Toshibas?
I think you will have to test it yourself?.
As far as I know Toshiba didn?t mention anything about compatible Blueray drives for Satellite A200.

The point is that not all drives are compatible due to different master/slave/c-sel settings.
Using not compatible ODD you will get an IDE #1 error message and the drive will not be recognized by BIOS.

But I read here in the forum that some guys managed to upgrade the own Toshiba units with a blue ray drive?
Therefore I?m thinking that you?ve got a good chance to upgrade it.

does anyone know what the cause of this problem may be - when i put a disc into my laptop to install new sotware - i see the following error:

***"D:\ is not accessible***

***The request could not be performed because of an I/O error"***



Answer:Satellite Pro A200 - CD/DVD drive issue - D:\ is not accessible

I can provide you a possible solution, which worked for many others already:

Go to device manager and remove the CD/DVD drive from the device list.
Then start the registry (regedit) and remove the Upperfilters and Lowerfilters values completely from the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class{4D36E965-E325-11CE-BFC1-08002BE10318}

After this, reboot your machine and windows will install the drive again. Check if this worked out for you.

Hi all,

I have a A200-1BW laptop, the issue is that its CD/DVD is not working. I have all the 3 recovery CDs for Windows Vista (Ultimate) provided by Toshiba, but I cannot restore my system. Is it possible to copy the recovery CDs on USB drive and then execute the system recovery for windows vista (ultimate).


Answer:Satellite A200 System Recovery from USB drive


I never tried that but I found this thread:

Check this. Maybe it would be helpful?

You can also try to install fresh copy of Windows OS using the USB pen drive.
There are many instructions how to do that with Win 7. Just google?
After installation of fresh Win 7 you could install the drivers from Toshiba European driver page.

I have just purchased an A200-1VG and whenever I load the "My computer" option it displays two hard drives but they are only half of what the overall hard drive space is. Is this normal?

Thank you in advance

Maybe you have misunderstood something. I hope you see two partitions on one HDD. Usually it is shown as partition C and D.

In Windows explorer it looks like on this photo.

Can any one advise me on my laptop Satellite A200-1yo.

I am currently rebuildingy laptop and as i go to turn the laptop back on the screen is black and doest give an opition to press any key to start the rebuild.

It has writing but doest want to rebot from the drive with the cd in it.

What should i do ?


Answer:Satellite A200-1yo doesn't reboot from the drive with the CD in it.


Did I understand you right?
You are able to power on the notebook and you can see the Toshiba Splash Screen at the beginning but you cannot boot from the CD.
Did you test different bootable CDs like Linux Live CD or Toshiba Recover disk?

Theoretically the issue could be only a faulty disk but of course the CD/DVD drive might be faulty too? if the CD/DVD drive cannot boot from any CD then try to clean the laser lens using cotton wool tip and alcohol.

A while ago my DVD writter stopped working. I have Windows 7 with latest toshiba drivers.

The DVD is reading fine the cd/dvd's inserted, the device is OK in Device Manager, but when writting a DVD it fails somewhere above 50% with "Unknown error".

I tried Nero and standard windows app.

What do you recommend?

Answer:Re: Satellite A200 - DVD drive can read but cannot write


Did you test different DVDs from different manufacturers?
I had a similar issue in the past? and since that I use TDK ?R DVDs and CDs and these disks work properly.

I recommend also cleaning the DVD drive laser lens using alkohole and cotton-wool tip.

Is there any info,as if we can replace our optical dvd writer with a *blu ray writer*? (not only reader...)
Thank you for your help.

Answer:Satellite A200-23W and blu-ray optical disc drive

It is very interesting question. I didn?t find any relevant info about Blu-ray ODD compatibility for Toshiba notebooks. Check Qosmio category.
Several months ago I saw one thread about it and one user has successfully upgraded his Qosmio with Blu-ray drive. Maybe is the same drive compatible with your notebook.

Is it possible to fit an additional internal drive to the A200-1DA?

Answer:Is it possible to fit an additional internal drive on Satellite A200-1da


it should be possible but you must first checkout if your machine has the connector or not. You can check this by opening the second hdd-cover and check if the connector is present.
If you don?t know where to search, just unscrew the covers on the bottom of the machine and look. :)

Answer:Satellite A200: DVD drive stop working


Did you try to boot from the Toshiba recovery CD?
Try to do this. If the CD/DVD drive can boot from the recovery CD then everything is all right with the hardware.
Sometimes the CD or DVD cannot be read due to the wrong registry entries.

So try to install the OS again and check if the drive can handle the Toshibas recovery CD!

If you still will be not able to solve your problem come back and we will try to solve it together ;)

When I try and load XP Pro SP3 (32 bit) it will not install as it has no SATA drivers. I have downloaded drivers and have an external floppy to install drivers by pressing F6. My question is the machine is listed as 64 bit and the XP Pro is 32 bit. Do I choose the ICH8M 32 or 64 bit drivers. IE does the 32 or 64 bit on the ICH8M refer to the hardware or operating system. Computer is Satellite Pro A200 PSAE4E-01700WEN.

Any help appreciated


Answer:Satellite Pro A200 does not recognise hard drive XP Pro


If you use the 64bit OS, then you should use also the 64bit drivers.
I found very nice ?HowTo? from Toshiba.

Check this! It?s definitely interesting and should be helpful.

ive got the toshiba Satellite A200-27z laptop & a while a go it wouldnt turn on at all, i took it to a computer repair shop & they seemed to fix the problem, except they delete all the 'stuff' what the laptop came with.

On the most part it still does the things i want it to do. but recently i went to play a dvd in it & it wont work, although it does play dvds if theyre sent to me through msn etc.

Normally, when i put a dvd in, the toshiba dvd player would automatically load up straight away, but now it wont. when i go to manually open the toshiba dvd player a message comes ups saying:

*the specific drive cannot be located. check the settings by going to settings > action settings > source. or otherwise check that the drive has been properly connected to the pc.*

ive gone into the 'action settings' but the source box is blocked (cant type anything in it). i dont know much about computers and so dont know how to check if the drive is properly connected.

it also wont recognise when i put a cd in it either, as normally if i put a cd in then itunes would automatically load up, now itunes wont show if a cd is in the laptop & i cant find it anywhere.

can anybody help, i have no idea with these things!

Answer:Satellite A200-27z wont recognise DVD drive

Windows 8 does not see hard drive on A200.
How to install?

Answer:Windows 8 does not see hard drive on Satellite A200

That?s strange? Windows 8 should already contain the HDD controller driver in order to recognize the HDD while installation.
Is the HDD visible in the BIOS?

Do you use original Windows 8 Microsoft disk?

Hi. Have a satellite A200.

Initial problem, would not boot up only power light on and hard drive light came on for a second, nothing on screen, not even access to F2 settings. Reseated memory, no go, removed hard drive and test and read hard drive ok in an external case. With hard drive removed computer will boot from after market boot disc and run diagnostic program ok. Can now gain access to F2 settings.

Format hard drive externally, reinstall and boot with boot disc, hard drive appears in bios, diagnostic test runs ok.
Tried to install Windows XP and XP pro and both times windows starts to install and then comes up with an error saying there is no hard drive present, even though Bios and a diagnostic boot disc both recognize the hard drive.
Tried another hard drive with same problem, not recognized.

Any Ideas?

Answer:Satellite A200 - Hard drive not recognized


Have you tried reinstalling Windows by using Toshiba recovery disk? Normally with this disk everything should work properly because it?s pretested and especially designed for your notebook.
Check this!!!

In worst case your HDD is faulty and you need a new one. The HDD seems to have random failures.

Everything else is fine, but when I put a CD into the disk drive nothing appears on my screen and it starts to make a clunking sound like it's trying to play but can't.

This laptop is straight out of the box. Is there any thing I can try before I take it back to the shop?


Answer:Brand new Satellite A200-1VG CD/DVD drive not working?

Usually the CD/DVD drive should run and works immediately after starting the notebook.
Did you try to insert the recovery CD and to boot from ODD?
Please check this!

If it will not work visit your notebook dealer to swap the unit!

I have a Toshiba Satellite A200 with a 32 bit windows vista, that was purchased about 4 years ago. It has become extremely slow and crashes on a regular basis. I want to format the C drive and re-install windows vista . I will subsequently re-install all drivers. I have questions about the process

1. I have the recovery disk provided by Toshiba. Is this enough to do what I need above? Does it also have windows, because I checked the disk and couldn't find the windows installation files

2. Will the recovery process format all partitions or only my windows drive (C:). I prefer if it only formats C: drive and not the other drives. However I am still backing up all drives just in case

Thanks for the help.


Answer:Satellite A200 - Format C drive and reinstall


Yes, for formatting the C drive and reinstall Windows with all drivers and tools from Toshiba the recovery disk is enough. Factory settings will be restored on your computer so you have the same settings as you purchased the computer.

Recovery disk will format the whole HDD so you have to backup everything on another drive but usually a backup of all important files should always be done and not just before reinstalling Windows ;)

Excuse Me
I have bought toshiba A200.
After two weeks My DVD/CD Drive doesn't work.
So I deleted ?ts driver and then I am not installing the driver.
Please help this subject.

Answer:Satellite A200: DVD/CD drive doesn't work


Please don't be mad at me but your posting is a little bit unclear!!!

However, the CD/DVD drive uses and supports the common Windows Vista (or XP) drivers!!!
You don?t need any special drivers to recognize the ODD?

In your case I would recommend accessing the device manager and to delete (uninstall) the CD/DVD drive.
After this procedure reboot the notebook.
The Vista OS should recognize the new device and should reinstall the drivers automatically?
