Have a look at the following pictres to determine if your hard drive is ATA or SATA:

Next, measure the length of your hard drive and compare it with the reported dimensions the enclosure will house. Use this information to pick out a compatible hard drive enclosure and use it.

Now, depending on your operating system and security options you may have difficulties accessing the data on your hard drive from another computer. In that case you will want to click here for information concerning taking ownership of the files.

Hope this helps,
