Hello,
So have this really annoying problem with an external HDD. I am running Windows 7 Enterprise on a Dell XPS 7500. The HDD is a Lacie d2 Quadra 2TB plugged into the eSATA port on the computer.
The problem is with the HDD disconnecting when I try to transfer files. Actually, when I first got the HD, it just wouldn't work on eSATA. USB and FireWire worked fine, but because they are slow and I am working with hundreds of gigabytes of data, I need the speed of eSATA.
What would happen is this... Windows would see the HD just fine, and I could access it, but the moment I went to copy files to and from it, it would hang and then disconnect. I would have to reboot my computer for it to be seen again. As I mentioned, it worked fine with USB or FireWire, and also on the eSATA connection of a laptop I have. So, the drive seems find and it is a system problem of sorts.
I installed new Intel Matrix Storage drivers from the Dell website, but that didn't seem to do anything...
I looked at the Windows event log, and sure enough there were errors associated with the disk. The problem seemed to be with a file hpdskflt.sys which was an HP accelerometer driver that is to protect the drive from falls. Not sure why it was on my system or if it was used, but it seemed like whenever the drive was being accessed, it tried using this file, which didn't work, so the drive hung...
So, I deleted this file from my system and removed every trace of it from the system registry. And voila! The drive seemed to work perfectly under eSATA. Very fast, didn't disconnect, etc.
However, about a week later, problems started again. Windows sees the drive just fine and I can access it, but if the drive goes unused for awhile, when I try to copy large files to or from it, it disconnects. However, upon reconnecting, it works just fine. But again, if I don't use it for awhile, it disconnects again.
Looking at the event viewer, the following things show up:
Warning: Event ID 51: An error was detected on device \...\DR2 during a paging operation.
Error: Event ID 9: The device, \Device\Ide\iaStor0, did not respond within the timeout period.
Error: Event ID 5: A parity error was detected on \Device\Ide\iaStor0.
These all show up at the time I first start using the drive, but after it reconnects and I start using it, no more show up.
So, although I can access the files and it works, the disconnecting problem is more annoying than anything else, but I am also worried that continuing to do this may damage the drive in some way.
Thoughts?
Thanks,
Mike
