Vista doesn't recognize my external USB drive

Last response: in Windows Vista

But it's a little more compicated than that. I'm hooking up an IDE drive. I'm using one of those external USB kits - it's a usb to IDE cable and a power supply for the drive. It works great in XP, shows right up in 'my computer' and I got some files off it. It's formatted NTFS and worked in this same PC as an internal drive. Vista (my vista 32 laptop and my 64 bit machine) loads up some drivers and tells me it's ready to use a 'usb mass storage device' but it does not show up in 'my computer'. It shows up in device manager under disk drives, usb drive and is 'working correctly and it shows up in 'computer management' where it tells me the drive has not been 'initialized' but it can't initialize it.

It's kind of an off brand, creative i/o, couldn't find any support on-line. The direction say it wotks in Vista, no drivers needed in XP or Vista, and trying to update driver in device manage it tells me I have best driver already.

Any ideas?

Perhaps the device is corrupting to the extent it is not recognized 'properly'. Properly meaning not showing up in My Computer. Vista is recofnizing it, or incorrectly recognizing it (confliction) as something other than what it should be displayed as. Driver conflict sort of thing. I had that happen with a wireless notebook adapter. Machine reecognized it with some other system driver on startup. As soon as desktop loaded, all I had to do was unplug it then plug it back in and windows would find recognize it correctly and install the proper driver then and only then. It worked as advertised. Have you tried going in to Safe Mode and then plugging it in?

I think I may be on to something. XP had previously had it working but when I just now put it back on the XP machine XP says it is 'uninitialized' - just like Vista said too, so, something happened to it, I guess, maybe in this external hookup attempt the data was corrupted - anyway XP at least offered to partition and format it so I'll see if that works. I didn't care about the data on it thankfully.

Thanks badge.

I have a similar device at work... at it works fine with Vista. Comes in really handy when you have a customer machine with a hosed Windows install and you need to back up their data before reloading it.

Oddly I just got a maxtor one touch4 and am getting much the same results.
In disk management it recognizes the disk as disk 1 (0 being the main drive)
and not initialized .
It does got on to say that it is write protected.
Im not certain in your case if this is the prob and mine is a USB only setup but
strangely XP missed it and Vista found it and installed drivers.
perhaps we could help each other.

The one thing that I have found is that maxtor will sell me the driver to perhaps reset the drive, Im not sure yet and maybe yours would do the same.
Possibly you are running into the same problem or maybe you can send me in the right direction.

I have similar situation - an old Maxtor 80gig NTFS in an external case and it worked working just fine on Vista for over a year, and still works on XP...so I think it's got something to do with Vista's security even though I didn't change anything - it stopped working after a windows update. Now nothing I do can get it working in Vista...but I can still access it over the network if I connect it to the XP machine ...WTF? If something were corrupted wouldn't it NOT work either place? If someone finds a solution I would love to hear about it.

Hi,

I'm having a similar problem. Last Thursday (11th June 2009) I was able to use my computer (vista SP2) fine. My usb pen drive worked fine. Something since then has changed because now the only way i can view my usb drives is through disk management. They worked fine before that date and continue to work on other systems.

I've tried assigning a disk letter but they still refuse to show in My Computer. The information is accessible via exploring whilst in disk management. The only way to make them appear stable in my computer is to create a folder on the C drive and assign the disks a folder on the C drive through which they can be accessed. Any news of this being a common problem?

Yes exact same problem. I have tried it with a 3.5 IDE, a 2.5 IDE and a 2.5 SATA. I have also tried it on 3 different compys w/ 3 different OS's. The 3.5 IDE works fine. I can't get and 2.5 drives to initialize/recognize.

I have 3 different external USB 2.0 HDD enclosures, a Manhattan, a Nexxtech, and a No Brand Name aluminum enclosure, all three are running Western Digital HDDs, and all three work and transfer problem free in Vista 32bit.

My machine is up to date as far as Windows Updates are concerned, so could this be a hardware problem possibly?

I noticed a few maxtor drives mentioned, remember the Seagate 7200.10 series issues, it could very well be hardware related?

Just a suggestion.

Could be. The 3.5 IDE that works fine is a Hitachi. The 2.5 IDE that doesn't is a Seagate. The SATA that isn't working either is a WD though.

Sometimes when people think 2 much they overlook the simplest anwsers. In vista disk management, when it says the disk is not initialized there will be a little red arrow on the disk icon on the left of the unallocated space. Right click on the little red arrow and select initialize disk. After you do this, then go ahead and format the disk how you want it.

Sorry to tell you guys but this problem is COMMON with Vista 64 bit. Yet another example of the extremely poor driver management in 64bit Vista (thx MS).

I got external drives to work for a while to work for a while by unchecking the "Allow the computer to turn off this device to save power" option in the device manager for USB Hub Properties, Power Management Tab.

That's not helping now.

There's also a suggestion that the C:\Windows\inf\INFCACHE.1 file may be corrupted and need to be replaced (either restore a previous version or just delete it and try connecting again). Ibelieve Vista recreates this file every bootup?

That has'nt worked for me either though :( .

I will keep investigating until I find a fix but I can't count the number of similar sytle problems with Vistax64 and external devices (usb drives, printers) that have been around for over a year and for Microsoft provides no fix.

If Vistax64 were a car it would have been recalled by now as unfit for use, yet Microsoft do nothing :(

I have Seagate mobile HDD in a USB-IDE enclosure. I had similar problem. Vista Home Premium seemed to detect it when plugged to the PC's front USB connector. HDD did not actually show up.

I checked Seagate for support. Seagate advised to attached mobile HDD to USB connector at the back of the PC. I followed the suggestion. It worked.

I hope this can work for your case also.

Apologies if this posts twice but my 1st attempt appeared to vanish.

It appears this problem is not OS related OR due to faulty device drivers - though it does appear to be most common with Vista it does happen with other OS (e.g. 32 bit XP).

There IS an effective workaround (not a permanent fix) - which involves a complete shutdown AND disconnecting power AND disconnecting battery (if laptop) for 30 minutes (I suspect you could do it for less time).

It appears the problem relates to the motherboard losing its ability to properly read the USB hub (I suspect this is a power management/load issue). This is most likely caused by an external event (like a power drop or pulling in a new device). The above "reboots" the motherboard.

Others have reported a fix due to completely uninstalling all USB devices and the main hub and then re-installing. Though some have said this didn't work (I suspect for those that did it may be due to the power down they would have done in the middle).

IF this is what is going on (issue has been reported for years) then it suggests motherboard design not up to scratch for more complex/power demanding OS - but this is just conjecture.

Regardless try this workaround. Has worked for me twice and is simple.

I have an external HDD connected via an USB to IDE/SATA kit. One USB wire and a power suply.
I have windows VISTA Home Premium.

For the first couple of times my external disk showed up in VISTA but lately it can´t be recognized.
(all the time it showed up in XP).
In VISTA diskmanager said "not initialized" and when I tried to initialize (right click) I got the answer:
"device not ready".

When lisening to the drive - it was VERY silent - like not rotating. Is this the reason "not ready"?

But if I FIRST connect the power cable and THEN the IDE-USB I hear the rotation sound. Now I can connect the USB into the notebook and the drive is recognized by VISTA.

It seems I first have to unplug the IDE connector from the external HDD and then insert it again. This activates my HDD.

Try this!!

I had the exact same problem and I seem to have a fix that works for me.
I was using a USB to SATA adapter to transfer data from two old hard disks and Vista would'nt recognize either. I could see them as "Disk 1" in "Disk Management" but it said the drive was not initialized. Right-clicking to initialize the disk gave a message "the device is not ready".

I found out my problem was a loose SATA power connector that would cause the disk to spin in the beginning so it was recognized by Vista but subsequently did not deliver power to the disk continuously. It worked when I wiggled the connect a bit. Now the disk shows up as a regular external USB drive.

Hope this helps.

I plugged a new Verbatim drive into my Vista computer, and saw the little prompt that said the device was ready for use, but couldn't see the drive in My Computer. After flailing around about and seeing references in this thread to Disk Management in Vista (I wasn't sure where to find that), this solved my problem:

I went to Control Panel, Device Manager, and double-clicked on Disk Drives. My drive appeared on the list, so I double-clicked on it. I clicked on the Volumes tab, and then clicked the Populate button. My new hard drive drive then appeared in My Computer.

Hope this helps someone else!

Take your HD to a windows XP machine. Plug it in and go to Disk Management. Right click - My Computer - Select Manage - Click Disk Management. It will find your drive and bring up a wizzard that you can follow. Then after format is done, right click unallocated dirve and make it active....

I have a similar problem, but it may be slightly different.

I have a few old HP Vectra machines that run Windows 3.1 and I want to move the files to my new laptop to save them before recycling the old PC's. I don't want to spend the hours to store the files on floppy disks, then move them to an old XP laptop that has a floppy drive, then burn to CD on the old laptop then move to the new laptop...........

I do have one of those external USB kits - a usb to IDE cable and a power supply for the drive. The USB kit appears to work fine. The drive spins when powered up, but Vista does not recognize the drive and can't see any folders or data.

Diskmanagement can see the disk, calls it "Disk 1" but says the disk is "unknown" "unreadable"

ComputerManagement/DeviceManager/DiskDrives appears to see the disk as a "USB Device" and the device properties say that it is working properly but it does not recognize any volume or any other details - not even the size of the disk.

Is there a driver that I can load or some other way that I can read these disk drives in vista so I can move the files I want to save to my laptop?

Thanks for any advice anyone can provide.

This particular post lead me to an answer. I suspected a power problem, and indeed my kit was plugged into an unpowered hub. The disk spun up and showed as "Not Initialized" in Disk Management. I clicked "Initialize" and received a "Drive Not Ready" error. That was probably a good thing because I didn't want to format the drive, I wanted to read some files that were on there.

In any event, plugging it out of the hub and plugging it directly into a USB port on the computer case worked for me. By the way, I had this problem even thought the USB kit had a power supply that plugged from the wall into the drive - however the USB wire from the computer to the drive could have still been weak I suppose ?

Anyway, good luck !

Hi folks, thanks for all the great suggestions. I solved my problem after following Anonymous's advice just above.

My symptoms: vista 64 desktop wouldn'lt recognize an external 2.5" drive I'd used many times to transfer multi GB of image files from laptop to desktop. ..some of the other solutions didn't work. I have Vista 64 sp 2 now on both laptop and desktop machines.

Anyway, like many above, external USB 2.5" drive would show up in Disk Management but not in My Computer.

Here's how I got it working: I went into Device Manager, but my drive wasn't listed under Disk Drives...however, down below, there was an alarm (yellow ! mark) under "other devices". I figured that had to be the drive. I right clicked on it as I recall, it offered me the choice to install a driver (by searching the internet), I clicked on that, it found and installed a driver, and bingo, my drive appeared in the disk drives list and in My Computer. I'm now transferring files from it to my desktop.

I notice the drive is FAT 32. Once I've transferred, I'll reformat as NTFS, I used to use this drive on an older machine I guess.

Maybe FAT 32 is part of the problem, hell, who knows with Vista. But it's now working, and I'll know next time from everybody's troubles to try everything I can think of, and thanks again for the help.

okay i have a peculiar problem as well, i'll intro with that.

as happy and motivated as i am to post this i am actually pretty much enraged inside.

i did a pseudo-install [yeah i made that up since there is no option of that matter, only clean or upgrade] of vista

and i shouldn't have overlooked it but i left my acomdata 160gb external plugged in the usb.

as soon as i got vista up and running again this is where i had problems.

the hd itself gets recognized under safely remove hardware with proper name and all. it does however, not show up on my computer or under the device listings to assign/change drive letters.

another thing to mention is it works fine on my mother's laptop and no files are corrupted.

i am in the process of just taking everything off it and temporarily storing it somewhere else so i can possibly punch this, pardon my language, piece of a *** *** and take some anger out then reformat it and place all the files back in.

i would just like to know if anyone else has has this problem and found a way to resolve it.

and nope, reassigning the letter doesn't fix it, i was hoping it would as i had conflict issues before where that was the solution.

When I checked the memory, it showed as before (almost full). I unplugged it, thinking it would help, but now after plugging it numerous times and even turning off the comp and all, it fails to even read it.

----------------------------------------------------------------

Well, here this thread is, months down the road, and I imagine there are a lot of people like me, who have looked over these posts and still haven't resolved the problem.

As a foreword, I never used Vista -- a few weeks ago, I went straight from Win XP Pro to Win 7 Pro 64-bit.

My experience is very similar -- I have two older HDDs from which I want to offload data before mothballing them. I tried an Apricorn IDE-to-USB adaptor kit ... I couldn't get anywhere with it. Thinking the kit might be defective, I traded it in for a similar kit from Vantech, which has come highly recommended -- users say it works flawlessly.
However, when I hook everything up, my system still does NOT see the HDD -- at least, it does not show up in My Computer, Windows Explorer, etc.

When I bring up Control Panel/Administrative Tools/Computer Management/Disk Management, it does not show on the colored "charts," but Disk Management does give me a message “You must initialize a disk before Logical Disk Manager can access it.”

Below that, in the same window, it says “Select Disk(s),” with only a “Disk 3” listed. It gives me the choice of selecting a partition style of either MBR or GPT (GUID Partition Table) ….. I tried selecting both – neither selection results in anything productive. I merely get a smaller message window saying “Device is not ready.”

There is nothing available by “right-clicking,” and since the “mystery drive” is not shown on the Disk Management graphical chart or anything, I have no way to try changing the drive letter.

NOTE: I have had the HDD jumpered (i.e. no jumper) to Slave from the very beginning of this frustrating adventure. Also, the USB plug on the adaptor kit has always been plugged directly into the PC, not on a USB hub.

I also tried connecting the HDD directly into the IDE port on the motherboard, with no better result -- that doesn't seem to bode well :(  The thing is, this IDE HDD was working just fine when I was using Win XP Pro .... and now it won't even appear using a ribbon cable to the IDE port ??

Thanks in advance for your thoughts and input ....

Hi all,

Battled this for a few hours, then came across this post. Had a similar scenario as already described: sata hard drive (3.5) hooked up via usb adapter. device manager saw it, but disk management said the device wasn't initialized and when i tried to initialize it i got a "device not ready" message.

I tried many of things in this post. What helped me was a post from noblablabla. to reiterate what worked for me:

turn on power to the HDD. Hopefully you'll hear/feel it spin. While it is clearly "on"and spinning, plug the usb cable in (sorry, i didn't try the USB hub, i just went straight to the back of the PC). So long as it was running when i plugged it into windows, windows found it, initialized it, and I had a working USB drive.

Hope this helps someone.

I had the same problem, tried all the forums, no joy. What solved it for me, now don't laugh but I was plugging the ide adapter into the hard drive upside down turned it around and it recognised the hdd straight away. Hope this helps.

I had the exact same problem and I seem to have a fix that works for me.
I was using a USB to SATA adapter to transfer data from two old hard disks and Vista would'nt recognize either. I could see them as "Disk 1" in "Disk Management" but it said the drive was not initialized. Right-clicking to initialize the disk gave a message "the device is not ready".

I found out my problem was a loose SATA power connector that would cause the disk to spin in the beginning so it was recognized by Vista but subsequently did not deliver power to the disk continuously. It worked when I wiggled the connect a bit. Now the disk shows up as a regular external USB drive.

Hope this helps.



Thanks dude! Spent 3 days looking for solution. Guess what, the power cord connected to supply was not plugged in. It appeared to be connected and absolutely did not give any indication that power was not in. I wish this damn thing had power LED!

step 1: if you see the "safely remove hardware" icon, go ahead and stop the USB device.
step 2: unplug the USB cable
step 3: remove the power cord, make sure the connector is all the way into the power supply unit and the power connector is firmly fixed to hard drive (you should hear the spinning sound from your external HD)
step 4: make sure the IDE/SATA connector is properly fixed, some IDE connectors have offset, if you use the connector edge as reference, one set of pins will be left out, make sure no pins are left out.
step 5: plug in the usb connector to your pc

after few seconds you should see Autoplay popup, if not refresh your explorer.
