Hi
Welcome to Apple discussions
Can you see the devices if you use Utilities/Disk Utility? Maybe you need to reformat them. Take care, reformatting will lose the data on the device.

USB flash drive not recognized by Macbook Leopard 15.1

Hi
Until last week my macbook was able to recognize my USB flash drives and my IPOD in Itunes and also as an independant drive.
Last week it started to give trouble. It simply does not recognizes any USB flash drives I plug in as well as my IPOD music into Itunes.
This is very strange since it is recognizing the HP all in one. It scans and prints. I purchased this HP all in one last week and installed the software for it. I am not sure how this could have affected that I cannot mount any USB drives.
Can you please help? Anyone?
Thanks.

USB flash drive not recognized on desktop or disk utility

I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!

Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions?

Boot Camp: Seagate External Drive not Recognized in Windows Explorer -- PLEASE HELP!

I'm running in Boot Camp and using a Seagate Free Agent GoFlex external drive as both a Time Machine backup on the Mac OS, as well as a storage unit to exchange files. However, whenever I plug my external drive into my computer while running Windows, it does not show up in the Computer tab under "Devices With Removable Storage", like it should. It does show up on the "Safely Remove Hardware and Eject Media" button in the bottom right hand corner, and it appears as a "Startup Disk" in the Boot Camp Control Panel, so I know that it isn't a cable or USB input issue. Please help me get it to appear as a Device in the Windows Explorer. I need to exchange files from my Mac OS to my Windows OS. Thank you in advance for the help.

I did it but i could not install tool from the dvd. As i said, i can still boot up windows xp i just needs to re-install the service tool.
The drivers are working properly.

USB flash drive not recognized by computer. Have tried all options of which I can think.

Okay. I have a Patriot S-Mini 32GB flash drive that my Windows 8.1 HP Slimline 400-434 is not recognizing. I believe it recognized it once, and has refused to do so since. My laptop (Windows 7 Toshiba) recognizes it just fine.
All other USB devices function perfectly on this computer. USB mouse/keyboard/USB Hub/Apple iPhone cable.
1. I have tried unplugging all other USB devices before trying this one. FAIL
2. I have gone to Device Management and the USB drive does not appear in the list. FAIL
3. I have uninstalled the USB Root Hubs and restarted the computer. FAIL
4. I have tried plugging the USB drive into the rear ports that plug directly into the motherboard. FAIL
5. I have updated the drivers, and have been unable to find a BIOS update as the link on the HP website downloads and says that it is incompatible for my computer. FAIL
...so what the bloody gorram heck do I do now?
This question was solved.
View Solution.

Okay, and in the most ridiculous way I have ever solved a technical problem...
The USB flash cannot be inserted ALL the way into the port. It has to be inserted slowly, so that the contacts line up.
I figured this out by trying to connect it into my USB hub and noticing that the red indicator light was going on and off as I inserted the USB drive, flickering on as I inserted it and then off once it was all the way in.
Weird. But hey. It works now.

How to boot from USB flash drive - Portege R500

Hi,
I have a Portege R500 running Windows XP, brought about 2 years ago, and recently contracted a worm virus that has infected some of the start up files as the minute I log in it logs out again, even in safe mode! Quickest way I can think of sorting it is to reformat it with the XP recovery disc and reinstall windows.
Problem!! The CD/DVD drive on the laptop stopped working a while ago, have tried pretty much everything in the thread on this site but had no luck.
So my plan was to boot from a USB flash drive and do it that way. However in the boot settings I only have the options of HDD / FDD / CD-ROM / LAN, neither of these will work. Does anyone know how to boot from USB flash drives?
Any help would be really appreciated

Hi
As far as I know it should be possible to boot from USB FDD
Im not sure if you would be able to boot from USB flash drive but its definitely worth a try
Generally you could try to press F12 button when notebook powers up.
Then a boot menu should appear on the display and you should see all bootable devices.
PS: As far as I know the USB booting was available in ToshibaHWSetup (Toshiba tool which changes the BIOS settings in windows OS.) Therefore I assume booting from USB should be possible.

Audio problem with boot camp when I connect my windows 7 macbook pro to HDTV

I have windows 7 32 bits installed on my macbook pro and I setup boot camp 4. When I connect my macbook pro to HDTV using mini display cable, the audio doesn't work. Although I set the default sound device to digital audio? help please!

I've found that jiggling with the audio connection to my Mac Pro when running in Boot camp, I get audio OK. I don't understand why -- because I always get audio when running in Leopard.

MSI P965 Neo-F (MS-7235) problem booting from USB flash drive

Hi, all!
I was wondering if someone can help me. I am trying to install Windows 7 x64 on my 320GB HDD that is connected to my MSI P965 Neo-F (MS-7235) mobo (The CPU is a Core2Duo 6600 with 6GB of RAM). I created a bootable USB 8GB flash drive using Microsoft's "Windows 7 DVD USB Download Tool" and bootsect.exe (Needed to create a boot sector on the USB drive) from the MS store. I successfully tested the resulting bootable USB drive using freeware MobaLiveCD (Sorry, you'll have to Google "mobalivecd" since this forum doesn't seem to allow external links) running under Windows XP SP3 x86 (32bit). Under MobaLive's QEMU, Windows 7 setup loaded its files and produced an error message basically saying that it could not install Windows 7 x64 under an x86 OS (No surprise there since QEMU is emulating a 32bit processor - The point is that the bootable USB drive I created works).
I then went into my mobo's CMOS and under Advanced BIOS Features -> Boot Sequence -> 1st Boot Device, set the value to "USB-HDD" and rebooted my machine. The USB drive probably was not detected by the mobo under that setting because it proceeded to boot from my HDD which is the 2nd Boot Device. I repeated the same process using each one of the four USB ports in the rear of the mobo (I don't have the optional USB panel that the MSI users manual mentions) to no avail. I also tried setting the 1st Boot Device to "USB-FDD" and repeated the process for each USB port but the mobo still will not boot from the USB drive (It does not recognize it). When I set the 1st Boot Device to "USB-ZIP" and rebooted, the mobo hangs after "Verifying DMI Pool Data ..." which is no surprise since I am not using a USB ZIP drive but a USB flash drive. It appears that under that setting, it recognizes that there is a USB device attached but it is expecting a response (From a USB ZIP drive). I had no idea it would be this frustrating to boot from a USB flash drive! If anyone knows how to make this mobo boot from a USB flash drive, please let me know. Any assistance would be greatly appreciated. Thanks!

The P965 Neo motherboard is 8 years old, so don't expect miracles. .... You need to format the USB stick in the proper way. You may use this utility to do it: hxxp://www.prime-expert.com/flashboot/ Also, it's a good idea to use the first (USB0) connector (controlled by Intel ICH8) for the USB flash drive. Good luck.
Thank You for your fast response, RemusM!
I'm not looking for a miracle. I'm just looking for a mobo that does what it is supposed to do: Allow me to boot from a USB flash drive (I don't think that is too much to ask for even from a board that was made in 2006)!
Thanks for recommending FlashBoot. I see under their "Why FlashBoot" section that it "... does not shift to user the burden of choice between "USB-ZIP" and "USB-HDD" at format time and proper BIOS setup at boot time. ... and every USB disk is formatted in such way that it will work in every environment properly, regardless of current BIOS setting.", so I will give it a try and let you know about the results afterwards.

USB Flash Drive not mounting

I recently bought an 8GB USB flash drive, which came formatted FAT-32. The drive was put into a friend's Windoze laptop and had a couple GBs of jpeg and avi files transferred to it. I took the drive home and put it in my white MacBook (4GB RAM, Leopard 10.5.8) and it would not mount. I put it in my G4 MacMini; likewise, it wouldn't mount. I am assuming it also won't mount in all my older Macs with USB, either. I returned it to the Windoze laptop, and it ALSO wouldn't mount this time, except as one pulled the flash drive from the Windoze laptop, for a second a window with the flash drive's contents would flash on the desktop of the laptop. Originally, the flash drive was "properly" ejected from the Windoze laptop.
On the MacBook, both Disk Utility and DiskWarrior do not see the flash drive when it is in the USB port (either port). However, Apple System Profiler does recognize when it is plugged into the port. ASP returns the following information when the flash drive is in the high speed USB port:
"Flash Disk:
Product ID: 0x3234
Vendor ID: 0x1221
Version: 0.00
Serial Number: 10000000000003CF
Speed: Up to 480 Mb/sec
Manufacturer: USB2.0
Location ID: 0x24100000
Current Available (mA): 500
Current Required (mA): 100"
Anybody have any idea what is the cause of my problems with the flash Drive and how I can get the drive to mount? I don't think the problem is a function of my Apple hardware, as my USB ports on all my machines function with everything else USB which I have without problems. Thanks.

I know that, but I have USB in my older Macs, too, and besides, some of the most knowledgeable people are in these older forums!!
I've come to the conclusion that the drive may be defective, too, but I was just looking for some possible angle which I'd not already considered. I tried reformatting, but without the drive even being recognized, it isn't even possible to reformat. I can only get ASP to indicate that it is attached.
Thanks for your try!

Satellite U400-10j - How to boot from USB flash drive?

Hello,
I have a Toshiba Satellite U400-10j.
I have Ubuntu on my USB flash disk, I now want to boot from it.
I am unable to find the option in the BIOS to boot from the Usb flash drive.
Secondly I have noticed that the laptop also has a internal memory card reader.
Could I load Ubuntu onto it then boot from the memory stick as well?
Your Help will be much appreciated.
Thank you.

I think its not able to boot from an USB stick on this notebook.
The best way is to use a CD. There you can boot from on this notebook and all other notebooks.
In the Internet are a lot of CD versions of Ubuntu and other Linux systems available.
And as Feliks said, its not able to boot from an SD card because this is not listed in the BIOS.

How to boot from usb flash drive on Satellite A500-o25

How do you configure boot order on A500-o25 so that it boots from usb drive first.

Hi,
Enter the Bios, pressing F2 on startup, go to the Boot menu and choose Usb drive as the first boot device (you navigate with F5 and F6 keys). Press F10, and ..Save and Exit menu ,, appears, press ok. That's all.
Note, on my satellite A500, I have to connect the Usb flash before to turn computer on, otherwise the usb flash drive doesn't appear in boot menu in Bios

Well, there are the on-line manual pages:
man ivman
man IvmConfigActions.xml
man IvmConfigBase.xml
man IvmConfigConditions.xml
man IvmConfigProperties.xml
And there are examples in the default files (/etc/ivman/) provided with Ivman.
But that you probably already know. I'm not familiar with any other docs, except maybe tutorials on the net if you count them as docs
