In an earlier post; Dell refuses to start after battery replacement. I removed one of the dell's hard disks and put it in my siemens/hitachi.starts up fine but doesn't show that there's another hard DISK. Should i remove/move those whiter plastic 'bridges' to different pins to make it slave /master?It should be jumpered as slave if it is a secondary drive...

Cabling:

MB===================================Master=========Slave.

Also...double check your primary drive...some need to be jumpered master/w slave when a 2nd drive is added...

PS. You shouldn't try to boot to the 2nd drive since it came from another machine if you have a version of Windows newer than WinME.Thank you for your time patio..the problem is that there are /is label on BACK of hard disk with symbols that i know not much about. It's international i guess but i am in sweden.So you write that it should look like you wrote: MB master...slave Is that where I put the little white plugs? please forgive my ignorance.I APPRECIATE very much your helpNo...that is how the cable is setup INSIDE the machine...
motherboard============================master drive======then slave drive...


Here is a picture of a common jumper setting:




Keep in mind all drives are not setup the same way...
