The drive will appear in the top of the disk management window? If so, look at the column layout, Type, file system and status. The "file system" must be FAT or NTFS. From your description, it appears that Windows does not recognize the partition as being to the format in a way that he can use. You may need to delete the existing partition (attention: this will remove all files that may exist on the disk), and then create a new partition in FAT32 or NTFS format.

Satellite M70 - after HARD drive partitioned, the OS does not start
Hello
Good then this is a real doozy, and I hope that someone will help.
I started to fix my satellite m70 girlfriends using the disc of recovery etc, everything went fantastic, the HARD disk has been erased and Windows + all software has been reinstalled.
Then I thought it would be a good idea to use partition magic to partition the hard drive, so I chose the main hard drive and cut 10GB of it to put in place a new partition.
I rebooted, and then after Windows restarted again completed.
NOW, it does not charge, it says no operating system, so I tried to start with the recovery disk and all over again...
If I click on continue (to start the recovery process), however it is said now that the "Error #1828", free space is too small.
I'm really angry that this has happened and I just want to start over again.
Can someone help me with this?
I can't access the Bios either (not sure if that might help), because I don't know the password (must be a fault im not aware of).Help, please.
Thank you
SGI think that this is the reason why you used a tool to change the size of the partition. At best, this should be done before you install Windows and 10 GB is a little too small for Windows. You must use at least 15-20 GB for the first partition where the BONE is placed.
To resolve this problem, you must delete all existing partitions before using the recovery disk. Therefore, you can use a Windows XP disk or something else. Just boot from it and delete all partitions. Then the recovery disk should work.

I had to reinstall Vista and now my display driver and the microphone does not work.
I recently had to reinstall Windows Vista on my PC. Now my audio works perfectly, but my microphone will not even if the Control Panel recognizes it is connected and working properly. Also, my display driver stopped responding from time to time and crashes my computer. Geek Squad, I need new drivers, and they want me to pay 130 to install. I'd rather do it myself. I tried to install the driver for my card NVIDIA and Vista, but that did not help.

Hi deaza,.
Ø Have you connected the USB hard drive to the computer directly or you have used an external USB hub to connect?
O trying to connect to another USB port to check if it works?
O the hardrive shows in windows of the computer when you connect it?
Method 1:
If you have installed security software, I suggest you to temporarily disable the security software and connect the USB and check to see if the same problem happens. Make sure that you enable the security software after checking.Alternatively, you can try to plug the USB key into a different USB port and check if it helps.
