Windows 7: Seagate HD's not recognized by Windows Explorer on new PC...

Seagate HD's not recognized by Windows Explorer on new PC...

I pulled two Seagate hard drives out of my older PC's (32-bit) and would like to be able to read them on my new PC. However, I cannot get my new PC (64-bit) to recognize them. It recognizes a Maxtor and another Seagate just fine, but not these two in question. They are as follows... Seagate, Barracuda 7200.8, 200 GB, 7200 RPM, both are model #ST3200826A. What's crazy is, I see that my PC recognizes them in "Computer Management/Disk Management" for a while, then it disappears. It doesn't give me the chance of assigning a drive letter to them. When I open up Disk Management, I don't see these hard drives. BTW, I am using an "adapter", in other words... the hard drive is laying in front of me and I can plug/unplug it as needed for testing. These are IDE, not SATA hard drives. I have changed the jumpers on the hard drives from, initially "master" to "slave" then to "cable select" without any luck. Please advise.

I've generally had poor results using adapters -- which I'm forced to do these days since my newer motherboard-based PCs don't have IDE drive cable sockets anymore. I often have to connect, unconnect, reconnect several times before I see the drive actually being recognized.

Also, some drives work better in this setup if there are no jumpers set. You should try that to see if it makes any difference.
