Multi Port USB Hubs: External Hard Drives Not Detected
Nov 27, 2009
I recently received a multi port USB hub and plugged it into my laptop. It seemed like a good idea as I only had 2 USB ports on my computer. This gave me 4 where before I only had 1 which made a total of 5. I plugged a new external DVD burning drive into one of the multi ports ports. The drive used 2 ports, 1 for drive and 1 for drives power. I also plugged 2 external hard drives into the other 2 ports. The burning drive would not work and 1 of the external hard drives was not detected in computer.

I have a program on an external USB hard drive. I want to run the program from that HD. It doesn't run properly because it needs to write files to it's folder, and it doesn't have permission to. If I turn User Account Control off, then everything works just fine, however I don't want to turn it off. Is there anything else I can do to get the program to work properly with UAC turned on? Should the program be writing files to a specific folder? I tried setting the permissions of the folder to 'full control', but all that seems to do is set the permissions on each individual file that currently exists in the folder.

Windows Vista operates external hard drives that are connected with USB differently than internal drives. Write caching is disabled so that you can safely remove the drive at almost any time. This is a great feature for USB thumb drives that are frequently inserted and removed from your computer. But if you have a large hard drive that is in an external enclosure that you never disconnect from your computer, write caching is also disabled which can decrease performance.
This tweak is going to show you how to increase the performance of your external hard drives by turning write caching back on as well as activating advanced performance. Let’s get started: ...

I am curious if Vista can be run from one of those portable external hard drives that I see in Staples, etc. rather than have to install another internal hard drive. I want to dual-boot with XP (already installed on an internal HD) and it would also be great if I can bring that external HD with us when we travel and hook it up to my wife's XP laptop and be able to boot up in Vista too. We need something for testing our software in Vista.

I have a Dell computer, had it about three weeks. I have two hard drives in a serial ATA Raid 0 stripe 500GB each. They are controlled by Intel matrix storage manager software. I want to have the two hard drives separate, like drive C and Drive D In the Bios I have two choices ATA or Raid, I have tried both ways to have them separate, however still can't. I have to say that I found this forum by chance, by goodness I am glad I did with drivers for my scanner and printer.

I have an external hard drive, I reformated it so I could use Vista's backup.Now it seems that when my brother inlaw tries to put some music files(Itunes) that the hard disc is unavailable to his computer. At this stage it seems that Vista has conned me into destroying a perfectly good WD harddrive!I have created a second partion on the hard drive and I am reformatting that, as I write this, but the only formatting option seems to be this NTFS, and that is what I had already formatted the ExtHD to so I think this formatting will be to no avail!From what I can figure I need to format into FAT but I tried a quick format an ex-fat option was there, but the problem was the same. I am becoming more frustrated with Vista, seems I just keep running into things that should be simple and aren't!

i just got my 500gb Seagate drive back after it bricked from the little firmware issue they had. I also just purchased a 1TB WD drive. I don't really trust the Seagate any more and want to use the 1tb drive as a backup. I had backed up everything 6 months ago but it's amazing how much stuff you accumulate in 6 months time.
I am not too knowledgable in hardrives. Not enough to do anything complicated. Right now i am running Vista Ultimate 64 on the Seagate. Could i put another copy of Vista on the 1tb drive and just copy what i want over to it? That way if the Seagate dies again i can go right to the other drive. This will not be an external drive, just another bare drive in the bay. I realize i'm not going about it the best or most efficient way. Some people have explained better ways but most of it was over my head. I just want to be able to unplug the bad drive (if it goes bad) and continue with the other drive. So, would i run into any problems with Vista (not dual boot of course)on both my drives? Does it sound like this approach would work?

I need to get a new external HDD for my laptop and I'm thinking of = getting an eSATA drive. My question is this: Can any HDD be turned into = an eSATA drive by housing it an enclosure which has an eSATA port or is = there something special about SATA drives? I'm not sure whether I should = buy an already enclosed SATA or buy the HDD and the enclosure separately = (cheaper option).

I have 2 powered USB 2 hubs connected to my vista PC - neither are recognised - i.e. if i plug my printer/mp4 player/camera etc into the hubs my Pc does not realise they're there. There are 2 ports on the front of the PC and 3 at the back - it makes no difference where I plug the hubs in, they are not recognised.
If i plug my printer/mp4 player/camera etc directly into 1 of the USB ports on the PC they are recognised.

I have recently upgraded to an Asus P5K-E motherboard. It support AHCPI SATA. I'm running Vista x64 on a Samsung HD753LJ 750GB drive. Shortly after installing I checked the Device Manager which showed the drive running in PIO Mode 4. I kept trying to set it back to DMA mode but to no avail. However, using HD Tune 2.55 it says my drive is running in UDMA Mode 8. I never knew it went that high.

I have 8 SATA drives (4 in a PCI Promise SATA controller and 4 in the motherboard controller) in my Vista Ultimate 64, and I would like to keep them spinned down most the time. I use power saving but only the PCI drives are shutting down after x minutes, the motherboard drives are still on. In windows XP worked fine. I also noticed that when I delete a file, the drives spin up again. Could be any windows service interfering? I have all the hardware drivers well updated.

When I get to the part of vista installation where it asks which hard drive I would like to install to it says there are no hard drives found. I have checked multiple times that the hard drive is hooked up correctly, but they are still not found. My hard drive is a Western Digital SATA SE Caviar 500GB. Also, I have looked for SATA drivers that came with my mobo (GIGABYTE GA-X38-DS4) but I don't see any that apply to what I need, as the only drivers that they appear to have are ones for AHCI/RAID configurations which I am not using.

I just added two new 1TB My Book external USB 2.0 hard drives to my system. They come formatted and partitioned, but it is formatted FAT32, all of my other drivers are NTFS and so I went in to the Windows Vista disk management tool (sorry I don't remember what it is actually called but it allows you to see all of your drives, partitions, etc.) to do a quick format to NTFS. However, it seems to be taking hours to do this.
I am guessing and this is my question. Am I right in assuming that the reason this is not a quick format is because it is having to do a full format in order to convert the drive from FAT32 to NTFS? How long should it take to format a 1TB drive?

I recently installed Vista Home Premium and one of my hard drives is not showing all the space that it use to. The hard drive in question is a 1 Tb hdd and was working fine in XP as were the other HDD's. When I installed Vista, all the other disk's worked fine except for this one. I have gone into Computer Management and it shows the drive as having 859 Gb of unallocated space that I cannot format. I am unable to create a New Simple Volume or any other volume types for this drive.

I recently re-arrange my 4 500GB SATA drives to provide better cooling. The system rebooted fine but every two or three days on booting Vista would kick me back to the BIOS starting screen, or, completely freeze, requiring a reboot. The system then wouldn't boot saying it couldn't find an operating system. Turning the computor off, and a restart would fix the problem until the next time. I resolved this by rearranging my hard drives so that Vistas C drive was the Motherboards logical boot drive. An obvious solution. My question is two fold. Why would BIOS find the Boot Drive sometimes and not others (The disks are not faulty), I perhaps don't fully understand how SATA operates. I have had no further problems to date.

I recently purchased a new system with Vista Home Premium 32bit OS. I have a couple of hard drives (Maxtor) that I would like to recover some files from but when plugged into the new computer, they just don't register. Can't see anything when using IDE or have the hard drives on an adaptor for SATA. The old drives do have XP Pro on them. Is there a clash between OS? How can I read and recover the info I need? I have gone to the Microsoft site to make sure I have all the updates. I have gone to Maxtor to download the up to date installation software. Still nothing. I have checked the BIOS and the SATA ports are initiated (and have talked to the manufacturer HP about the issue and they can't see a problem). I have been able to recognize the old hard drives when I still had the old computer (cleaned it up and gave it to my son with a new hard drive installed). Would like to recover data and start using the old drives as a back up system.

There's a mystery drive partition on my system. confirm what it's used for/by? I'm running a triple boot of Server x64 RC2, Vista x64 SP1 RC, and Vista x86, installed on two internal hard disk drives. These are SATA drives, but not hybrids. They both have 8MB caches. (One is a Samsung HM250JI. The other is a Hitachi TravelStar 7K100.) I also have 1GB of Intel's Robson NAND. Now, in Disk Management, a 513MB (sic) FAT32 partition is there, called NVCACHE. It's listed as its own HDD, sandwiched between HDD 0 and HDD 1. So, there are two possible explanations as far as I can see: 1st candidate explanation: There's an Intel page that discusses Turbo Memory, which uses the "NVCACHE" term when describing its support for Vista ReadyDrive and "T13 specification Command Handling," which I had assumed applied just to hybrid hard drives, not to regular HDDs.
The other thing that's fishy is the 513MB cache size. Where'd the remaining 511MB go if this system has a full 1GB Robson NAND? Was I gyped out of 512MB of NAND? 2nd candidate explanation: This has something to do with the SATA caching functionality that I have enabled in the x86 partition. [See: Device Manager -> Disk Drives -> right-click on a SATA drive -> Properties -> Policies -> Enable Write Caching on the Disk -> Enable Advanced Performance.] If that's the purpose, then the question is: Do I need to confine my use of the SATA cache to one OS installation, or am I safe to enable this function in all of the OSes simultaneously? (Will overwrites by different OSes of each others' caches destabilize the system or not?)

I have evga motherboard with built in Realtek HD audio (ALC883). Board features 2 ports for digital audio (optical and coaxial). and according to manual both are output. However when installed vista drivers one of the ports has been chosen as digital output (optical) and another as digital input (coax) (i can see that when i hover the mouse over the jacks in "Realtek HD audio manager") Is there any way to make the coaxial port as an output port instead of optical? My my HT reciver has no free optical ports so i have to use coax to get some sound from the computer.

A few days ago, a message saying "windows detected a hard disk problem" appears when I log into Vista. Initially, nothing happen. Suddenly one day, my Vista started lagging(very serious). I therefore make it to be a USB external HD, and then try to copy the files. However, the HD stops working when reaching certain sector while copying. I attempt to repair it by using chkdsk tool and Seagate repair tool, the process stopped at a percentage. Any solution for me to copy my files please?

I have built a new system to game with and have 2 new hard drives, on one I put XP Pro and then on the other I loaded Vista. I have more or less completed all the driver upgrades and windows updates but I keep getting repeated boot failures of Vista. I can always get into Safe mode but in Normal mode the boot fails just after the first spash screen at the point when the screen goes blank to be replaced by the small circular
Vista logo. After 2 or 3 attempts it succeeds to load but then the problem seems to reoccur, particularly when I have been back to XP for a while. I had a similar problem with XP but that seems to have sorted itself out. I have tired looking in the logs for faults and failures but no clues there.

I created file backups on two removable network hard drives so I can regularly do incremental backups on the alternative disks. I want to keep one disk offsite and switch them regularly. When I try to alternate backup network hard drives the incremental backups fail. Message reads: ???The backup location cannot be found or is not valid.??? How can I regularly make incremental backups to these alternating removable network hard drives?

I have two physical hard drives. Both are identical. I want to move my Page File to my second drive to see if I get a performance increase. I did some research and learned that you must keep a small page file on your C drive because Windows writes a small amount of data to the C drive upon boot. Does anybody have experience with this setup?

I recently bought a western digital 1TB hard drive which I had to reformat before I could use. Everything works good now, except for onething. Sometimes the computer doesn't want to restart while the new drive is plugged in. If I remove it from the USB port prior to restarting, it will restart just fine.
It shuts down and turns on without an issue. This only happens when I
restart the system with it plugged in.
So while it's not a big issue,it is an annoyance.
