USB hard drive on vista

By chao129 ·
i have a seagate freeagent 320 GB external hard drive, which has had a few problems with vista before, but now has decided not to work. I've tried deleting INFCACHE.1 , updating USBSTOR.SYS, i have tried it in every USB port on my laptop, the drive itself if just fine, works normally on my Windows XP desktop. Under the device manager, it shows up as a USB mass storage device, but not as a drive. When I uninstall the device, it shows that it failed to install. Under properties from USB mass storage device in device manager it says "the device cannot start. (code 10)"
Lots of important stuff on it, that does little good without being able to access it from my laptop.

See if this will help

by Jacky Howe In reply to USB hard drive on vista

Connect the drive back to the XP PC. Open System Restore and stop monitoring that drive.
On the Vista PC try this.
Write down all fixed Disk and CD/DVD drive letters so as not to delete them. DO NOT delete any of the fixed hard disk drives or CD/DVD optical drives registry values.
1. Login with Administrative privileges.
2. Disconnect all USB or FireWire storage devices.
3. Open Registry Editor by typing regedt32 in the Run box and navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
4. Under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices there will be registry keys with the name that resembles the format of \DosDevice\X: where X can be any alphabet letter which corresponding to your physical system drive letter.
5. Delete all possible USB drives, FireWire drives and external drives which have a drive letter.
<b>DO NOT delete any of the fixed Hard Disk Drives or CD/DVD optical drives registry values.</b>
Exclude \DosDevice\A: which normally reserved for floppy disk drives.

Still broken

Tried your suggestion, but to no avail, still only shows up as just a USB mass storage device, not as a drive

Did you try

by Jacky Howe In reply to Still broken

a powerd USB Hub. < edit >

You say it has it's own power. Does that mean it plugs into an electrical outlet.

Well if the issue is on a NB loaded with Vista

by OH Smeg Moderator In reply to USB hard drive on vista

The problem is more likely to be the NB rather than Vista. Modern NB's have a very low current available from the USB Ports to make them run longer on Battery. As these external HDD's run entirely off the Current provided by the USB Ports you need to use at least 2 different USB Ports with the Y Cable supplied with the drive to get enough Power to run the drive correctly.

Any External Drive over 80 GIG's needs to have either a USB Y Cable in use, a Powered USB Hub to plug the Y Cable into or a External Power Supply for the Enclosure.

If this drive has worked previously on any Vista Loaded computer it's not a Chip Set Problem with the Circuity inside the Enclosure that is an Interface between the USN and the HDD Connection. As it works on a different computer loaded with XP it is unlikely that the Hard Drive itself has suffered any damage through either overheating, Vibrational Damage or constantly lacking sufficient power to work it properly.

But if you persist with attempting to use it on a system that is Incapable of providing enough Current on the 5 V DC USB Port the Drive will suffer damage as there is not enough power to run the HDD Properly so the Windings in the Motor that drives the Platters will suffer Damage if nothing else occurs. I would however count on the Drive having greater issues than just the Platter Drive Windings failing.

Power is not a problem

The drive lights up, I can hear it spin, and it has its own power cable anyway.

only a little help

by odiebugs In reply to USB hard drive on vista

Unless your motherboard has a external drive port,sata,firewire, that is set as a drive,
the os will see it as mass storage and not an internal drive as if you had it pluged into the external sata port.Then it would not appear as mass and show as local. As for vista,it should pick it up better than xp with drivers. Try installing the driver from cd that came with drive. If the drive works on another machine and all your sd cards and flash drives work in your usb ports,,,,sorry im lost. It would be better if this drive is formatted fat and not ntfs using usb, as a port.As for important info on it,just copy it with your windows xp desktop, and reformat the drive then try it on your lap.

Well it could be that this Device is not compatible with Vista

by OH Smeg Moderator In reply to USB hard drive on vista

It is quite possible that a recently installed Patch has closed a Loophole that allowed a Incompatible Chip Set to work sort of right under Vista.

But double check the External Plug Pack to make sure that it actually has power from the socket that it is plugged into. After all if you are moving this Plug Pack to different Sockets it's not impossible to have a Faulty Power Strip where one or more sockets no longer have any power to them.

If you can plug it into the XP Machine and confirm that it's working correctly then Using the Safely Remove Option stop the drive unplug just the USB Lead and plug that into the NB and see if it works now. If it does replace whatever it is you are plugging the External Plug Pack into. Also double check the Plug Pack Lead and the USB Lead it is possible that under some conditions they may not work correctly and then when in a different position they do.
