External hard drive not able to access data

October 22, 2010 at 10:19:26
Specs: Windows 7, Intel TM2 Quad 2.5GHz/ 6GB
I have an external hard drive caddy to recover data from a hard disk used as the C drive on a PC running windows XP the motherboard having failed. My new PC runs Windows 7. The drive was installed in the enclosure according to the caddy manual as 'master' and runs without a problem. When the USB connection was made the PC installed the drivers recognised the existence of the mass storage device but did not allocate a drive letter. In Disk Manager it can be seen as 'disk6 unknown not initialised'. Right clicking the disc 6 entry and choosing initialise brings up the error 'Device not ready' I have tried running the disk as slave but with the same result.
The hard drive is a Hitachi Deskstar Model:HDS722516VLAT20 capacity 165GB 7200RPM PN;14R9247 MLC:BA1254 LBA:321.672.960 SECTORS CHS: 16383/16/63, an IDE device I believe. My new computer I think is SATA.
Other information
1. The hard disc spins.
2. The fan and LED lights on the caddy are working.
3. The capacity of the disk is 160GB.
4. There is no icon on the bottom right of the desktop.
5. In Disk Manager it is described as a Mass Storage Device and connected to the Universal Serial Bus controllers and is described as 'disc6 not initialised 96GB unallocated.I've been struggling with this for a while and any ideas would be appreciated.
6.It is not possible to allocate a drive letter.

Thankyou for any help

See if Hitachi have diagnostic software to check the drive to make sure it's ok after the mb failure.
Another thing you can try is connect it directly to your mobo if it has a ide connector.

I agree, most SATA motherboards also have at lease one EIDE (PATA) connection for up to 2 devices. By installing it this way, you will be bypassing the USB controller and the need for any drivers since your motherboard should recognize it directly and so should windows. If this does not work, you could try their diagnostic software, but it is probably gone. It is possible that it was the hard drive that went rather than the motherboard, or that the motherboard (if really bad) allowed incorrect voltage to reach the drive.

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.

Thanks for the information guys I'll follow it up. Just a bit wary of opening up the new PC at present as it will negate the warranty.

Way back, my first Gateway 2000 Windows 95 rig had one of those factory stickers over the case opening and I was nervous about opening it and breaking the seal. Eventually when I had a power supply fail on it, the factory was willing to send me a new one with instructions (as if they would be needed) if I was willing to install it, since it would save me the time of sending it back (and me and them the shipping cost and risk), I found out that that particular sticker just stayed on the cover but just popped of the back of the system case and could be pressed down again. That does not mean that they are now that way, but you just reminded me of it again...
