I install the software from the disk after i install thew usb drive it keeps saying need to install usb adapter

When you install Windows on your new SSD hard drive you can then transfer data from your old hard drive using an USB hard drive adapter or install the old hard drive into an USB hard drive adapter case and use it as an USB external hard drive after you have transferred your data to your laptop.
When you connect the USB hard drive adapter to the laptop, the laptop will see it as an external storage device, you can then open the various folders anf files and copy them to your new hard disk.

An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files. For example, see: https://services.seagate.com/index.aspx?lng=en-US for a "no data - no charge" guarantee.

you can try some data recovery software. You can see
http://www.asoftech.com/adr/
It tells the steps how to perform data recovery.

If above does not work, you may have to format the hard drive (use quick format), and then use above mentioned software to scan again the hard drive and recover your files.

Most of the time, "self-inflicted" damage is EXCLUDED from W.D.'s "warranty" for the drive.
So, it depends on your sense of "ethics" whether to file a warranty-claim.

Device Manager only says that the disk is getting AC power, and that the "data" cable is connected, and that Windows has recognized the specific device-information (that it is a disk-drive, and that the capacity of the disk-drive has been recognized).
Device Manager does not say that the "spinning" part of the disk-drive is still spinning, nor that there are any I/O errors (trying writing with a pen onto greased paper -- not everything you write can be read).

If it still is not "readable", then you have a few options:

* if the warranty still is valid, exercise the warranty, to get it repaired/replaced,
* disassemble the case, disconnect the disk-drive from the USB-to-disk-drive adapter, and connect the disk-drive as a "slave" drive in some desktop computer, to see if the USB-to-disk-drive adapter has failed
* buy a replacement disk-drive, connect it to that USB-to-disk-drive adapter, and close the case, to create a "new" external disk-drive.

You upgraded your PC what OS is your new system? Win 7?. Most probably the software you downloaded for your USB or PCI wireless adapter is not compatible to new OS.

From the model you mention Netgear WG111 (USB)? Drivers are for XP. Maybe you can download a newer version that support your OS.

The operating system software is stored on the hard disk. The computer cannot detect the hard drive and therefore cannot load the operating system. It could be that it only needs reseating to get it operating again, if that does not work it could be a faulty disk drive or a faulty disk controller.
To test if the hard drive is OK, remove it and connect it to an USB hard drive adapter and plug this adapter and drive into a working computer's USB port. If this computer see this as an external hard drive and you can view the contents of this drive, then it is OK. If you cannot see this drive then it is faulty.
You need to replace the hard drive in your computer and install Windows again to get an operating computer again.
