Laptop USB Ports Stopped Working - External Hard Drive
Jan 1, 2006
I have a Sony VGN-T1XP Vaio laptop with an Intel Pentium M Processor running XP Pro SP2. For some reason the two USB ports have stopped working and no USB devices are recognised. I have looked at the device manager under USB controllers and there are four USB controllers listed which are as follows: Intel 82801DB/DBM USB 2.0 enhanced host controller 24CDIntel 82801DB/DBM USB universal host controller 24C2Intel 82801DB/DBM USB universal host controller 24C4Intel 82801DB/DBM USB universal host controller 24C7 Underneath those are four USB root hubs.
I have previously used a USB card reader and external hard drive on both ports without any problems but now when I connect any device nothing at all happens.

I have lost access to all the USB ports on a PC. There was no apparent crash but I realised there was a problem when the USB Mouse stopped working. Everything else is working OK. I get an Error 39 (drivers corrupted or missing) and the 2 entries in Device Manager both have yellow marks against them. I only have "Standard Enhanced PCI to USB Host Controller" and "Standard OpenHCD USB Host Controller" entries below the entry for Universal Serial Bus Controllers - no Root Hubs are there and there are no Unknown Devices anywhere else.I was running XP Pro SP2 when the ports went, but have installed SP3 and Updated to see if that did anything - it didn't. I have tried the troubleshooting suggestions on Microsoft such as deinstalling and rebooting, updating, system restore and have done a repair installation using my original XP SP2 disc all with no result.

My CPU has been 100% for over a month. I first thought it was a virus so a scanned w/ every program out there and nothing would detect anything, HJT log was reviewed and nothing found so I went down the Registry Path and tried to repair with Registry Repair Tools to no avail. So I backed up all my files and did a complete OS re-install in CPU is still at 100%. And when this problem first started by USB ports stopped working.

I've got a bit of a problem with my computer and was hoping some advice. Basically all the USB 2.0 ports on my computer have recently stopped working - I can still use them to charge my iPod, but not to communicate with it (I no longer get the little icon in the bottom right hand side of the screen when it's connected), and I can't use my printer because the computer insists it's off-line (I've tried two different cables so it can't be a problem with that).I've got two USB 2.0 ports on the back of my computer (built into my motherboard - can't remember the exact model offhand but the processor is one of those 2800+ Athlon 64bit ones, if that?s relevant) and I've also recently upgraded my monitor to a dell FPW2005, so I've now got another couple (not working) on the side of that too. I even tried taking the USB 2.0 card from my old computer (that has 4 USB 2.0 sockets in it and plugs directly into the motherboard) - but this didn't work either

My laptop stopped working and it was pre installed with Win XP. I've lost the system recovery disk buta friend gave me theirs. when I inserted it I was asked for a serial number and duly put in the one on the bottom of the laptop but it was rejected.Nothing would work so I exited the menu and went out and purchased a brand new copy of the O/S. However when I put the disc in it keeps taking me back to the old screen which asks me for a serial number and it wont accept the one form the disk I purchased.

I have a Dell computer where one of the loading .dll files came up 'missing' one day, so it won't boot. I want to get all the photos and other docs off the hard drive. I had downloaded one version of linux and was able to see the files on the internal hard drive, but was unable to copy them to a memory stick or external hard drive. Now I've downloaded ubuntu and booted off a memory stick... this time, it's telling me that the internal hard drive has all kinds of bad sectors and won't let me access any of the files on there.

I am cloning my existing hard drive in my laptop (sata) to an external hard drive (pata) in preparation for installing a new larger hard drive (sata)in the laptop. Can I, or how do I transfer the cloned data from the external (pata) to the new internal hard drive (sata)? Thanks in advance and I apoligize if this is a rudimentary question as this is my first time attempting something like this.

My sis has one of those Wally-Mart Acer mini laptops; NO CD-ROM drive in it (PS: way-bad idea! Never buy a computer w/o a dvd/cd drive in it!). She managed to delete the graphics card driver and so when that occurred and rebooted, nothing on-screen! Its there, you just cannot see anything in windows! And, because there is no drive, the CD with all the original programs cannot be run in start-up mode without an external CD-ROM drive
I want to use my (HP Pavilion zv6000 w/XP) laptop as that external drive to re-load her original CD, which (of course) has all the drives on it! At start-up, the Acer (also w/XP) has an option to start-up from an ext. drive, so it has that capability (obviously, w/o a drive of its own), but how to make my HP "look" like an external drive (via USB-to-USB hookup) is the problem!

Last week I was hit with a multitude of viruses. Since then I've followed
the KRC Anti-Spyware tutorial, I have ewido, spybot (tea timer running), Ad-Aware, etc. and cleaned everythign up, and my system is finally stable again. I even got Norton System works and that helped a lot too. I've been to Windows update and am completely up to date with installs.2 problems still: I still have no audio, and 5 of my USB ports are not working

I've connected an external USB drive, but when I go to My Computer it shows it as a network drive. In addition, it gives it the same name as the mapped network drive that already exists there. When I change the name of the external drive there, it then changes the name of the mapped network drive, so again they both have the same name, although the drive letters are different. Any ideas how to make the external drive appear where it belongs in My Computer, under Hard Disk drives?

I turned the PC off to reboot when I though I was going into safe mode and went into regular mode instead. Now, it thinks one of my external drives is the C drive. On boot, I am getting a message that it cannot recognize find the system 32 windows config file (I'm paraphrasing).
I used the repair utility to get to the C prompt (which is pointed at the external drive) and checked the drive letters. I don't think the PC bios knows the hard drive is there.
I tried going into setup and reverting to factory installed configuration and that didn't change anything. I could not get it to recognize the hard drive.

My laptop died and I removed the hard drive.i hooked the hard drive up to my new laptop via a SATA/IDE cable.
I can see the old hard drive in the E drive and it appears that all the contents are there by the size of the hard drive (same as when I had it in the old laptop) but I can only see, actually view, a very small percentage of the drive.
My goal: I want to transfer all old music, word documents and photos from old laptop into new laptop.

I downloaded something stupid and probably got a virus as a result of it. A day or so later, when I next turned on the computer, it only got as far as loading the background to the Windows XP login screen, not the dialogue box itself, then rebooted. When it rebooted, it sounded like the hard drive stopped for a second, then started again. I formatted my hard drive, and after discovering that having a second hard drive connected causes Windows setup to crash reinstalled Windows XP Pro. It didn't help; in fact the reboot happened even earlier, while the Windows XP Loading screen was up. I went back to XP Home, and now the computer will get as far as it originally did, but doesn't reboot, it just freezes.

Recently, my motherboard fired, but the Hard drive was uneffected. Since i had a lot of info on the hard drive i tryed to find people who could take the info off the hard drive for me. I then had this great idea of just putting my hard drive into a "Hard Drive Enclosure Kit". Well, i did that and it worked great. But theres one problem, I can't seem to get into the Owner folder of the hard drive, for evey time i do, it brings up.

I just recently purchased a 100 Gb laptop hard drive together with an outer case and a USB cable. I just wanted to upgrade my laptop's hard disk, by first making an image of my current drive into my new one through the outer casing. The thing is when I connect it to my laptop, windows cannot detect it. Whats wrong with it? Is there anything I have to do?

Found some very useful info on here so decided to sign up and post a recent problem i encountered with an external hard drive. the hard drive has a capacity of 80GB and came from another pc. there was a 25/55 partition already on it from the old pc. i tried to delete the partition that was 25gb. now i can't find that 25gb at all. when i plug it in to the usb slot i can only see the 55gb partition it used to appear as 2 hard drives in my computer and nothing else. when i use disc management to format it i only see 55gb.

To anyone that might be able to help... I've had this external hard drive for a long time and I haven't been able to access it to store lots of music and videos on. My computer sees that it is there, but like I had said earlier, I can't use it. It won't let me see it unless I go to Device Manager. My computer is getting old on me and it's been places most labtops shouldn't have gone... Once in Purgatory, and now, it's on Hell's surface. I get the safely remove hardware icon down by my clock, but I don't want to remove it, I want to use it. I want it to show up in my drives so I can instantly see how much space I have left and what not... I went through the Troubleshooter, tried every possible way that I can think of, the ways the troubleshooter.

I have a Sony VAIO desktop running Windows XP. I purchased a Comstar 160MB External USB2 Hard-Drive and installed it. Since Windows XP is supposed to have the drivers that are necessary, no driver disk was included, and none was needed.The problem developed when my Windows XP began to give me problems later. I had to re-install Windows XP. I did that, and I downloaded all Windows XP up dates (including Service Pack 2). Now, this Windows installation does not install the external hard-drive. Windows recognizes that there is "a USB2 device," but Windows states that there are no drivers and asks me to furnish them.

I'm partitioning an external hard drive that's connected to my Win XP machine. I set an 80GB partition for XP (NTFS). When I tried to allocate the rest of the drive as a FAT32 partition (for my Win98 machines), FAT32 was not an option, until I reduced the partition size to 20 GB. I'm using XP's Disk Management. Is there a maximum limitation of FAT32 partition size?
