USB Drive detection issues

Hello,
I have been using a 16 GB Sandisk Cruzer Fit thumbdrive for the past year. I tried to access it this morning and it has no files on it. I checked properties and it says 0 out of 0 GB available. I tried the drive in another computer with success. I am able to access a 1 GB thumbdrive on this computer...What's the problem? What other information do I need to supply?

I also can't perform a system restore. Any suggestions?

USB drive access issues when using Windows Backup Win7Pro

I've run into a similar issue. I'm using an RD1000 USB drive which uses hard drives as removable media. There's an alert which states "Windows backup needs a CD/DVD or USB Drive to continue." It then states I
can continue the backup on the existing media or insert blank media. By simply selecting Continue the backup will proceed but this interrupts the backup every night so the backup won't automatically run until that challenge is responded too. I checked
permissions and reloaded the MS windows driver for the drive. I tried exFat and NTSF formats. Not sure how to force it to automatically proceed. The backup is only a tenth of the size of the total available drive space. Any
ideas?

USB Drive Sharing Issues

Hello -
I'm trying to connect a USB drive to my AEBS and share its contents across my network and have been very frustrated by the experience so far. I've gotten to the point where I can see the drive on the network but I cannot see any of the existing files on the drive. If I plug the drive directly into my mac or pc, I can see everything as expected.
I am even able to create a new folder and then a new file within that folder. However, even that newly created folder and file don't show up after creation. Again, I can see newly created folder and file just fine if I connect the drive directly to one of the computers.
I've tried many different things trying to get this to work and am about ready to give up.
The drive is FAT32.
File Sharing is enabled.
Security method is "device password" (I can't connect to the disk at all via Windows if I choose 'disk password').
Guest access is set to Read and Write.
When connecting via the "Map Network Drive" in Windows, I can see the "full/used" information, which is accurate. So the drive is being seen as is the fact there is data on it.
I have seen a couple of very old posts suggesting to create a folder called "Shared" and put the files in there. I tried that as well but nothing changed. I still could not see any files on the drive.
I see similar behavior on both Mac and PC. Finder kept hanging when trying to eject/disconnect the volume so I confined most of my testing to my PC.
Any help you can provide will be appreciated.
Thanks.

Boot drive detection issue [solved]

Hi,
I upgraded my Arch install yesterday (pacman -Syu). The last one was four weeks ago. Among the packages updated were the stock kernel 2.6.17 and mkinitcpio, so the update generated another image /boot/kernel26.img.
Now I am having random errors while booting. One out of two (yes, 50%) boots ends with kernel panic while identifying the root fs type after initramfs and modules have been loaded. Something like "Can't find device dev(0,0)".
The apparent reason is that sometimes the boot partition is identified as hda2, sometimes as hde2. Because I have the kernel option root=/dev/hda2, boot is successful when boot partition is identified as hda2, and fails with the above message when it is identified as hde2.
My particular hardware is a Abit Be-6 motherboard (quite old) which has two ide ports and two other ide ports controlled by a Highpoint HPT366 controller (which support DMA 66). My HD is connected to one of those.
I suspect that the drive detection relies on some kind of information sent by the bios and that this information is sometimes sorted in one order, sometimes in another one, i.e. sometimes the ide ports first, sometimes the hpt366 ports first.
For information, the install cd-rom would see my drive as hde (always, not 50%) and until yesterday, the boot process would see it as hda (again, always, not 50%).
So now the questions for you, talented forum participants, are:
1/ I would like to understand how disk and partition letters/numbers are allocated: why hde2 and not hda2? Can I force the naming to hda2, whatever the Bios says (for example based on a HD ID or a IDE port ID)?
2/ I read the mkinitcpio wiki. From what I understand, I can configure what modules will be loaded at boot time for detecting my boot drive, either at image generation time, or at boot time with a kernel parameter. Would blacklisting ide modules and leave only hpt366 module help? Conversely, assuming I plug my HD in an IDE port, would blacklisting hpt366 module help?
Help will be much appreciated.

Michel F wrote:The only thing is that I guess I have now to include /etc/mkinitcpio.conf in the NoUpgrade list in pacman.conf to avoid surprises when it upgrades.
The /etc/mkinitcpio.conf file is marked as "backup" in the mkinitcpio package. Therefore, if the default configuration changes, it will be extracted as /etc/mkinitcpio.conf.pacnew and your own configuration won't be touched.

USB/mount drive detection issue (using AIR 2)

I'm creating a drive mount listener in Flash Builder. For the most part, it works well. Lately, I have had a problem actually getting the event of a drive being mounted.
    var s:StorageVolumeInfo=StorageVolumeInfo.storageVolumeInfo;
     s.addEventListener(StorageVolumeChangeEvent.STORAGE_VOLUME_MOUNT,USBM ounted);
Then the handling method:
    private function USBMounted(e:StorageVolumeChangeEvent):void
        Alert.show("Drive Unmounted");
        printDirectory(e.rootDirectory);
My two questions:
- Has anyone ever used this method to read all drives being mounted (CD, SD card, etc)?
- Is there any way to get this to work using a USB hub?
Thanks

> You can write on "usb" because the right are : drwxrwxrwx
They appear only when I use 'sudo mount -o rw,noauto,async,user,umask=1000' instead of plain 'sudo mount /dev/sdb1 /mnt/usb2'.
I use vfat for that USB stick, so maybe that's why it works for me. The first two listings in your first post show the drives in different order, but of course the mountpoints show that the offending drive is ext2 not vfat, my bad.
Edit: This is how my ext3 USB stick behaves like:
[karol@black test]$ sudo mount /dev/sdb1 /mnt/usb
[karol@black test]$ mount | grep sdb1
/dev/sdb1 on /mnt/usb type ext3 (rw)
[karol@black test]$ ls -l /mnt
total 8
drwxr-xr-x 2 karol users 4096 07-03 01:08 usb
drwxr-xr-x 2 root root 4096 2009-09-14 usb2
This time /mnt/usb is an ext3. As you can see, there's no root, I (karol) an the owner, so I can rw to my heart's content. Maybe you should change the ownership - 'chown' (man chown if you're not familiar w/ that command).

WRTSL54GS USB drive access issues

Hi,
I have a Linksys WRTSL54GS (FW 2.06.0) for a bout a 2 years and have never used the USB port until now. I have WD 640GB (FAT32) BookShelf and I can't seem the access the drive through using shared feature.
1) Can't access the shared with any user id other than guest. I've created users but can't long in from my vista computer or laptop with any created user or admin ID. Can access drive with the user ID guest only.
2) Can't see shared directories or files.
3) Can't write to shared directories.
I've been trying to solve this problem for days with no luck.
Anybody have any idea what could be the problem?
I even tried using USB jump drives and still same problme. I've convinced it's the linksys WRTSL54GS. The feature I bought it for doesn't worked and I should have tried it when I first brought it.
thanks.

Anywone again? I hate to have to buy another router. I don't think I would bother with linksys if I have spend money on another router.

SATA / PATA Drive Detection Issues

I have my SATA hard disk on the primary (0) SATA channel and my DVD-RW on the primary PATA channel. This has worked fine since I've had this set up, but I've recently run into some trouble with it.
I hooked up a PATA hard drive in place of the DVD-RW to pull some data off it. When I tried to boot, it only detected the new drive and couldn't boot from it (Win 2000 blue screen). It didn't even see the original hard drive.
I messed around with the various modes under "On-chip IDE Configuration" and no matter what I do I cannot get it to detect 2 devices at once. There doesn't seem to be any consistency to the results it produces.
I have updated to the latest BIOS (2.2).
Firstly, why can you select SATA / PATA Only, and then keep the other enabled? What is the best setting for my two drives? I originally had it set to PATA Only and keep SATA enabled I think (on advice from people on this board).
If i'm not using RAID, I can disable "Onboard Promise IDE" right?
All help greatly appreciated.
Many thanks in advance.

The most likely reasons for the SATA to not be detected in the Standard Cmos in the order I would check them:
1. Data and power cables firmly connected(remove and re-attach to be sure).
2. Bios>>Integrated Peripherals>>On Chip IDE Config:
- SATA Keep enabled-Yes
- Configured as Raid- NO (Yes removes it from the Standard CMOS Features)
3. Drive no good
Make sure you have other IDE HDD's removed till you get this working again.
And yes, if you have nothing attached to Serial3&4, IDE3 you can set the Promise controller to Disabled.
Edit:
Oops, I didn't see the last post. Glad you got it!

Apple Mobile Devices Support USB Driver issue

While I am aware this is a somewhat common problem, I have already followed all suggested routes I've seen for fixing it, and none have worked. My computer seems unable to detect my iPhone at all, and seems to fail to install the AMDS USB Driver (though all other elements of iTunes appear to install correctly.
Here is some relevant information to help troubleshooting.
I have already stopped and restarted AMDS and enabled automatic startup (http://support.apple.com/kb/ts1567)
I have already uninstalled and reinstalled iTunes and related services (Including AMDS) (http://support.apple.com/kb/HT1923)
I have tested all relevant hardware, including the iPhone itself, the connecting cable, and the USB ports that I've used, and all are functioning correctly (The iPhone can connect to other computers using the same cable, the computer can connect to other devices using the same USB ports)
I have the newest version of iTunes available (11.1.5)
While Apple Mobile Devices Support is installed, the USB Driver associated with it does not appear in the device manager. I have checked all folders in the device manager, including (but not limited to) Imaging Devices, Portable Devices, and Universal Serial Bus Controllers.
There are no "Unknown Device" entries in the Device Manager
My operating system is WIndows 7
Both before and after reinstalling iTunes completely, Windows is unable to detect the iPhone in any obvious way (My Computer screen, Device Manager, etc). The USB driver for Apple Mobile Device Support is not disabled, but rather does not appear at all.
What could be the cause of this problem? Is there a way to install the USB driver by itself without installing/reinstalling the related iTunes applications?
Any help on this issue would be greatly appreciated.

really? so apple.com arent checked by those who work on apple improvements? that would be kinda stupid im my ears. some comments here have an answer from ppl with an apple symbol, "specialists" they call them self. need some respons from them maybe.
i have tried everything, worked fine before the latest patch, so why cant it be a driver bug? they are humans too, they who make drivers. they just have to admit they had done something bad here, and solve it fast.
can i download an old itunes or something so i can atleast send my photos over.
the PC dont even say "couldn't install driver" or what it says in english, nothing happends at all. the drivers are there.

HP USB Drive not detected

I bought a new 16GB HP USB Drive a day ago. The drive is not recognised by my mac. When I plug the drive in nothing happens.
- other USB drives work as normal
- I tried both USB ports (i.e. it's not a mac hardware issue)
- the USB drive works with my PC
I don't see the USB drive in the disc utilities option. Can anyone suggest what I should do next?
Thanks in advance
Ian

The following worked for me like a charm but you have to try it at your own risk.
1- Using Bootcamp switch to Windows. It will detect your memory flash HP 16 GB.
2- Click on my Computer, then right click on HP 16GB icon
3- Select Format
4- Format your Flash selecting FAT32
5- When finished reboot back to MAC and you are ready to go.
Hope it works for all.
You don't need to boot into Windows, you can format the drive using Disk Utility in OSX

USB has power, but not detecting any USB drive. Also crazy trackpad.

I own a 2012 Macbook Pro, and I am running OS X Version 10.9.4 on it. Everything was working fine until last week, when the USB ports stopped working. Now, the USB ports still have power because the lights in my USB drive and external hard disk turn on when I insert them into the system. However, the OS X is not able to detect any of these devices as well as my USB mouse. I have Windows 7 installed on bootcamp, but there is no USB response in Windows 7 as well.
I have done the SMC and PRAM reset, as suggested on numerous other discussions, but there were no improvements.
To add to all this, the trackpad on my macbook started going berserk. The pointer has started to randomly click and drag, while I am not even touching the trackpad. It is extremely hard to move cursor to a particular folder, because the cursor will click and drag a lot of times, while it has reached its destination. Also, the trackpad acts insensitive in certain regions. I tried cleaning the trackpad (as suggested on other discussions), but the problem goes away only temporarily. It seems, after using it for a couple of hours, the problem is back again.
With USB and trackpad not responding, it is getting hard to pass the first week of school. I took it to IT department at my school, they checked it for a couple of minutes, and told me that I'll have to shell out $280 for sending it to Apple Depot. I'll really appreciate any kinda help!
Thanks for your time!

Hi @Ak7
Welcome to the HP Support Forums!
I understand that you are having trouble with your USB ports not recognizing most devices. I am happy to assist with this.
Since it just recently started to happen, I would normally recommend starting with a system restore to a point before the problem began. (say about a week ago or longer if possible) Unfortunately you have already done a reinstall, so there should not be any useful restore points to use.
Presumably you already backed up any data you could before reinstalling windows, and if so, then you could try a system recovery, which would restore the factory image of the notebook. Give it a try and let me know if it makes any difference.

IPhone 5 iOS 6.1.4 and Windows 7 x64 USB Driver Issues

Been pulling my hair out with this one for the last week or so and haven't had any luck finding anything on the forums or the web regarding a solution short of a full reinstall of Windows 7 which I am not prepared to do at this time; so hoping someone here can shine some light on this for me
I have a iPhone 5 that is updated to iOS 6.1.4 and a recently built Windows 7 64-bit machine. All of my other USB devices function fine (keyboard, mouse, Xbox 360 wireless receiver for Windows, and a Seagate 2TB external USB drive). I've downloaded the most recent version of iTunes, installed successfully and then attempt to plug in my phone to sync. I get the standard Windows *ding* that I've attached a device and 1 of 2 things happens (I haven't been able to determine what causes one reaction to happen versus the other): Windows will successfully install the 'Apple USB Mobile Device Driver' successfully and it will appear under my USB devices in Device Manager. However - iTunes will not recognize the phone and I cannot see it in Windows either. In the 'Devices and Printers' snap-in my iPhone will appear under 'Unspecified Devices' as the 'Apple USB Mobile Device'. The iTunes diagnostics fail to find a connected device so the tests fail. As soon as I unplug the device, the strangest thing happens: Windows will start trying to install a device driver and after a few seconds it will fail stating that the "MTP Device Driver" installation failed because the device was unplugged. iTunes also thrown an error "iTunes cannot connect to this iPhone" throwing error code 0XE8000065 (I've also seen error code 0XE8000085 as well)
After some finagling, I've managed to get Windows to recognize the device under 'Portable Devices' in Device Manager as an "MTP USB Device" using the generic driver. At this point, I've tried updating the driver and manually specifying the Apple USB driver located in the C:\Program Files(x86)\Common Files\Apple\Mobile Device Drivers which updates successfully but then changes the device to "Apple USB Mobile Device" and moves it under the USB Devices in Device Manager; and Windows nor iTunes can see it even still.
I've tried removing iTunes several times and ensuring that all remnants of the installation are gone (registry and folders on the installation drive) and have disconnected all my USB devices short of the keyboard and mouse and still I get the same results. At this point, I'm afraid that a re-install of Windows is going to be the solution; but it's a drastic one (I have a SSD drive where Windows is installed along with all of my games for faster load times/better performance and do not want to have to redownload\reinstall all of them) and I'm not prepared to undertake it at this time, which is why I'm posting here
I've used a utility called USBDeview that sees my phone is connected - so I know from a functional standpoint that my USB ports are good and working. I also know the cable is good too - my daughter's PC (Windows 7 32-bit with NO iTunes) immediately sees the device when I plug it in, installs the drivers, recognizes it as an iPhone and I can then see/browse it in Windows Explorer like I would normally expect. My work PC (Windows 7 64bit, NO iTunes) sees the device just fine as well. I would immensely appreciate anyone that has seen this issue or has any additional solutions I can try.
It's also worth mentioning that I've never used Kapersky antivirus so the UPPERFILTERS value in the registry that I've seen as a solution on some forums is not present on my machine. I'm using Microsoft Security Essentials as my antivirus (no flaming please lol - it meets my needs and is extremely lightweight, which is why I'm using it on a gaming rig) and it's not indicating any issues. I've also tried running iTunes as an administrator (even though my account is a local admin on the machine) and that does not have any effect either.
If there is anything I left out, please let me know; and I thank you in advance!

Performance Issues with 10.6.7 and External USB Drives

I've had a few performance issues come up with the latest 10.6.7 that seem to be related to external USB drives. I have a 2TB USB drive tha I have my iMovie content on this drive and after 10.6.7 update, iMovie is almost unusable. Finder even seems slow when browsing files on this drive as well. It seems like any access to the drive is delayed in all applications. Before the update, the performance was acceptable, but now it almost unusable. Most of the files on this drive are large dv files.
Anyone else experience this?

Matt,
If you want help, please start your own thread here:

And if your previous thread you aren't getting sufficient help for your iPhone, post a new topic here:
http://discussions.apple.com/forum.jspa?forumID=1139
You'll get a wider audience, and won't confuse the original poster. Performance issues can be caused by numerous issues as outlined in my FAQ*
http://www.macmaps.com/Macosxspeed.html
If every person who had a performance issue posted to this thread, we'd never find a solution for the initial poster. Let's isolate each case one by one. It is NOT necessarily the same issue, even if the symptoms are the same. There are numerous contributing factors at work with computers, and if we don't isolate them, we'll never get to the root cause.

Mac Pro not Detecting Bootable USB Drive to Install Snow Leopard 10.6

Hi
I have to Mac Pro 2 x 2.8 GHz Intel Xeon. I have been running Leopard on them. I wish to install snow leopard, so i took out my USB HDD where I have made a Bootable Partition with snow leopard. I have used this in the past on all my machines to install snow leopard. Now when I try to install Snow Leopard from this on my mac pro, it does not detect in the "Option Boot" start up menu, it only shows my leopard disk. If I got to start up disk in system preference, then it shows my Snow Leopard disk, but when i select that as start up, it still boots to my Leopard..
Since I am doing a fresh Install , I have another HDD installed, formatted for snow leopard. When I launch snow leopard installer from Leopard and select install in the new drive, it does some installation , but when restarting it goes to my leopard again.
This is the case on both the Mac Pro;s, but not on my laptops, I tried on my air and my macbook pro, and my friends mac book pro, it instantly boots up to the usb drive with snow leopard.
So is there anything im missing ? Or is there something wrong with my Mac Pro's?
I dont have the snow leopard DVD, else I would have tried that too..
Please advice asap!!
Thanks
Sa1

Hey
Thanks for the reply!
I have two USB HDD, with the copy from snow leopard dvd, and both are formatted in GUID, they work fine on my laptops and even the old mac mini, just not working on two identical Mac Pros.. Its very strange, as it keeps booting to leopard, and if I remove leopard Disk, and just put the new one and connect the USB dive, its shows a folder with a "?" mark sign!
And the USB just works fine after its booted to leopard, it even starts installing snow leopard to the disk i assign, but it does not complete the installation as it boots to main leopard drive..
I have tried to reset PRAM on both machine, I have changed usb slot..
I dont know what to do!
