Question about Western Digital 320GB MyBook External USB 2.0 Hard Drive
I am running Windows XP Home SP3 and I have two WD External USB drives connected to my desktop. I am using USB 2.0 cables (the light up kind) and the hard drives have their own power. They are both connected to a PCI USB 2.0 card with four slots total.
Everything worked fine until I disconnected the drives from the USB slots to move the computer and remove a stick of RAM I needed for another PC.
When I reconnected the drives and powered on the computer the drives were no longer detected. They don't show up in my computer, or when I use disk management. They both work fine on my laptop. They are seemingly connected properly, because the USB cables light up when they are connected, and the USB card is seated correctly becasue it detects my flash drives.
There are no problems showing in device manager like question marks or exclamation marks. I tried uninstalling the USB entries in the device manager, rebooting and letting it detect the drives again, with no success. It recreates entries for the USB controllers but still the drives aren't detected. I have a separate USB slot on the front of the computer, but neither drive is detected there either. I've tried connecting the drives separately, one at a time, with no other devices connected, and powering them up after the PC is on, before it's on, etc, etc, to no avail.
The only other thing that was changed was that I had 1 Gig of Ram and now am only using 768.
My PC is a Pentium 4 2.4 Gig. with a 750 watt power supply. Besides the two external drives, I also have 4 internal drives. 2 IDE and 2 SATA. Again everything ran fine before I disconnected the drives from their USB ports.
Any suggestion would be greatly appreciated. Thanks.
There are two possibilities:
The Mybook USB/ATA controller board is faulty.
In this case you can simply take apart the enclosure and mount the disk into a new enclosure. WD Mybooks are SATA, but double check the hard disk connector to ensure.
The hard disk inside is faulty.
In this case repair may be expensive. You need to locate a data recovery facility with a 'clean room' , the cost is usually more than $800.
If this happened after a power surge, then the problem is most likely a faulty controller board.
If instead you have dropped the hard disk it is possible an hard drive failure, in that case repair will be expensive.
A replacement enclosure will stfrom art about $20 on Ebay or Amazon, and must not necessarily be WD .
Check if your disk is Sata or PATA (IDE) before buying the enclosure.
