If anyone can help - bless you! For the longest time I have needed to reformat my computer, which I simply cannot do if I do not backup my files somewhere. So I bought an external hard drive (Western Digital, Caviar Black, 1TB, SATA) & an enclosure (NexStar3). (This is my 2nd purchase like this and the 1st one worked fine, only it was an IDE drive). My computer is an HP Pavilion running Windows XP. This enclosure I recently bought has the option of USB or eSATA and came with the cables for each option. Since my computer would not recognize the new hard drive with the USB, I bought a USB to eSATA Bridge Adapter. I tried the adapter and the drive is still not being recognized when I turn it on. I tried to partition the drive but it does not show up in the Device Manager. I only see default empty drives (used for removable storage). I do notice a couple drive letters missing that were assigned to my other external drive or flash drive (they are not plugged in). I also checked the BIOS and do not see the external drive there. Looks like my system DOES support SATA. Is there anything I can do to get this external drive working? It's all I need to finally get my computer to normal again. I've seen similar problems as this and have tried the suggestions. Feel free to ask any questions or for any info I missed. I appreciate the help!!
