Recognising which hard drive is which

  Podracer 10:19 04 May 09

HP desktop with two identical 500GB hard drives - has been diagnosed with a faulty main C hard drive, and HP have sent another to replace the faulty one. How do I recognise which is the master C HDD and which is the secondary D HDD. HP have been of little help on the phone, and the identification they say should be there, isn't. Both HDDs have what looks like a power cable, and also a thinner (not the old ribbon cable)red data cable. These terminate on the mother board in sockets marked SATA0 and SATA1. SATA2 seems to go to the DVD drive. Any ideas if the SATA0 or the SATA1 cable leads to the master HDD2? Advice very gratefully received.

Sata0 will most probably be your 'c'drive.

But you don't need to worry because it won't break if you unplug the wrong one.

Having said that, presumably you are going to have to re-install windows and it has been my experience that it is best to only have one sata drive plugged in for that process.

After installation plug both the others back in and you can then transfer any data off the original c drive if needs be.

Many thanks for your advice - I'd guessed it might by SATA0, but was simply trying to avoid a trial and error situation while I changed one, tried to re-load the OSS (Vista HP), found it was the wrong HDD to change, and then had to go through the whole ish again.
