If there's another device on the same IDE channel (CD, another HDD, whatever) this drive should be set as a Slave. Because it came out of a machine where it was the primary drive, it's likely set as Master. It could be freezing the computer you're trying to use for data retrieval cause there's already a Master on the channel & the devices conflict.
Master/Slave is almost always accomplished via jumpers, normally located between the power & data cable connectors. You might have to go to the mfr's web site to find the jumper settings, but most drives are labeled, either on the top or near the jumpers themselves. If it's set as Master or CS (Cable Select) try setting it as a Slave device. If Windows took a shit but the drive is otherwise readable, you'll see it as a new drive letter and be able to retrieve your data files.
