Ibook not ejecting flash drive

Hello all, I have a problem ejecting flash drives from my ibook g4 12" 1.33 ghz. Whenever there is one plugged in, the light on it is always on and when I try to eject it, it says that it is in use and that it cannot be ejected. I have Norton AV software on my ibook so I don't know if this will affect it. Please send me some suggestions. Thanks.

In addition, some flashdrives have two components.
My SanDisk has only one desktop icon, but my Memorex has two icons, for some reason.
If a flashdrive mounts with two icons, draw a circle around both with the mouse to select both, and drag both to the trash.
As noted, the lights mean little, and on some flashdrives, the light is on the underside and cannot easily be seen.
I wait for a minute or so before removing the drive after ejecting it.

Really Need To Eject Flash Drive Before Taking Out?

Hi,
On a PC, you can just pull a USB Flash Drive out of a USB port, without any problems. If you do this on a Mac, it warns you of data corruption, and suggests you eject it first. But, do you REALLY need to eject via software on a Mac? Isn't it just a precaution?

I'm sorry we keep going back and forth on this. I don't know where you are getting this erroneous information from that "without a full eject first the drive may still be vulnerable."
It's really very simple. By default, the OS tries to optimize performance by delaying any requests to write data to slow devices by pooling together multiple write operations into a cache and then performing all the write operations at once (flushing the cache) when the OS determines that it has some idle time to do so. When you eject or "Safely Remove..." the device, the OS forces a cache flush command, thus immediately performing any write operations it may have not done yet. When it is done emptying the cache it displays a message that it is now safe to disconnect the device.
If you select the Fast Removal feature in the device manager, the write cache is disabled, so all data is written to the drive immediately and no cache flush is necessary. If you issue a "Safely Remove..." for a drive that has the Fast Removal option enabled, Windows simply ignores your request because there is no cache to flush. It simply skips the flush operation and immediately displays the message saying that it is now safe to disconnect the device.
There is always the possibility for data loss (especially if you do something silly like yanking the drive out while it's being written to), but if you have the Fast Removal feature enabled, ejecting or doing a "Safely Remove..." does absolutely nothing magical that will make the drive less vulnerable. Of course, there is no harm done in ejecting a Fast Removal device because your request is ignored; but if the placebo effect makes you feel you are somehow less likely to have data loss, by all means go ahead and do it.
Again, this is only for Windows. OS X does not have a Fast Removal option available from its GUI.

Ejecting Flash Drive

I just purchased a SanDisk 4 GB Flash Drive which I hook up to my USB dock. I have been using a 2 GB SanDisk Flash Drive which seems to be operating differently than the 4 GB. I know you are not supposed to remove the flash drive when it is blinking because you may loose some of your data. My 4 GB does blink like the 2 GB. Is it OK to remove it when the light fades in and out? When I go to eject it by moving it to the trash, the light fades in and out. Do I have a defective flash drive? My 2 GB does not do this. I hope I have explained this right.

My SanDisk has only one desktop icon, but my Memorex has two icons, for some reason.

MacBook Pro not detecting flash drive

Hello,
I have a MacBook Pro laptop (latest model) and I've encountered a bit of a problem with it.
When I plug a USB flash drive into either of the USB ports on the laptop, the computer fails to detect the drive and show it on the desktop.
However, when connected to my Thunderbolt Display and with the USB drive connected through the monitor or even through the keyboard (which is connect to the monitor) the laptop detects the USB drive without any issues. Also when I connect the keyboard directly into the laptop via USB and then plug the USB drive into the keyboard it detects it just fine.
The problem only occurs when plugging the USB drive directly into one of the laptop ports.
Any suggestions on how I can fix this?
Thank you

Yeah, it's just one drive. I think I figured out what the problem is. The USB drive is very old and cheap, most likely USB 2.0 but the ports on the MacBook Pro are USB 3.0 so there might be a compatibility problem.
In theory that should not be the case since USB3 is supposed to be backwards compatible to USB2. Perhaps the solution is to copy the data to a new device and trash the old drive. At least the cost will not be excessive.
Ciao.

Trouble ejecting flash drives with Snow Leopard

About every other time I try to eject my flash drive from my MacBook it freezes up the computer. My wife has the same problem on her computer. Is there anyone else that is having this problem and what can I do to fix it? Thanks!

Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:
http://support.apple.com/kb/HT1379
Can't hurt to try, and apparently this has helped others recently.
Also, try reformatting that flash drive using Disk Utility w/Snow Leopard...windows format only.

Finder does not show flash drive but it is mounted.

After reformatting a drive to FAT it was automounted to the /Volumes directory. I checked and it is there with all of the content there. Disk Utility also is telling me that it was mounted. The weird part is that the Finder does not have the drive in its sidebar. What else is weird is that other drives come up in the sidebar. Reformatting the same device and changing the volumes name will make it come up.
How can I make it show up in the finder?
Is it possible that I somehow blacklisted volumes with that name?

its not on the desktop. I have Finder not put the drive icons on the desktop.
well then turn that option on temporarily in finder preferences->general.

Recovery media program not recognizing flash drive in USB port

I have a new NB505-N500BL netbook. I am trying to create a backup using the Toshiba Recovery Media Center.
However, it doesn't seem to recognize that I have an 8GB flash drive installed.
Everytime I hit "create," I get the message to insert a 7.7GB flash drive. When I hit "OK" I get a msg to insert a flash drive greater than 7.7GB.
The 8GB flash drive is installed. I've tried it in all 3 USB ports. I've tried inserting it before turning ont the computer and afterwards.
I bought the flash drive directly from Toshiba so it should be good. I also assume a new 8GB flash drive meets the requirements of 7.7GB.
Any suggestions?
Thanks!

Hi Emma,
Contrary to what the size it's asking for, it's possible that the drive is just slightly too small. Even though the data may fit on the drive you have, the way TRMC calculates its free space may be slightly off. If you wish, you can try building this by hand and see if it fits. As follows:
1. First format the USB drive and make it active.
2. Now reboot the machine hitting the <F8> key until you are presented with a menu.
3. The first option should be "Repair...", then hit <ENTER>
4. You will be present with two login screens and eventually arrive at a repair menu.
5. First open up a command box and leave it open.
6. Now go back to the menu and launch the "TOSHIBA Recovery Wizard".
7. It will eventually get to a warning screen. Don't go pass this warning screen.
8. Once it gets to the warning screen, toggle back to the command box.
9. All you need to do is copy the contents from (I believe it's drive Q:\" to you root of your USB drive.
"robocopy Q: (USB Drive letter) /E /R:1 /W:2
10. Once everythings copied (assuming it fits), <Cancel> and the warning screen and then try rebooting from your USB drive.

Auto Eject Flash drive at Logout

I work in a computer lab at my college and one of the common issues we have is people leaving their flash drives behind. I want to create a script/automation that will upon logout display a window reminding the user to remove their flash drive.
Any ideas as to what the best way to approach this is? (Automator/AppleScript/Etc.)
And where to begin?

how about this:
paste the following into Script Editor and save it as an application
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
tell application "Finder"
if number of disks > 6 then display dialog "please remove your flash drive"
end tell</pre>
Instead of 6 put the number of disks you normally have on that computer. save it as an application somewhere. then make a logout hook to run this app on logout.
to do that run the following terminal command
sudo defaults write com.apple.loginwindow LogoutHook /path/to/app/you/made
put the path you've just made in the above.

Bios not recognizing flash driver

Lenovo G5030
excuse me guys
i have problem when i enter to Bios setup to change settings inside I was not find usb drivers to change it
and I want installing windows and there are problem about it
please any one can help me in that

Hook the hdd up to the same cable as the optical drive. If you are seeing the drive in a raid screen and it is hooked to an ide port, it has to be on the via controller. If you leave it on the ide1 channel then you don't need any drivers. If you want to put it on ide2 or ide3 then you are going to have to use the F6 option when installing windows to install the via drivers.

Tiger "quits" when eject ext flash drive???? Addressless addressbook

Folks:
Issues continue to crop up with Tiger, unlike those seen in Panther. A week back was finishing up working on a document which I saved to ext flash drive--closed the writing app, moved doc into flash drive, then ejected Flash drive by control/click and then maybe closed another app or turned off airport wireless &&& then got black window saying "You need to restart your computer." Then after restarted got an error window that said something like -- "You had to re-start your computer because OSX quit in the middle of what you were doing." OHHHH, the computer crashed!!!!??? I have ejected the Flash drive many times without this problem. Console crashreporter log showed single line entry for the time period that it happened--Thu Jun 21 17:41:44 2007 crashdump[94]: crashdump invoked as panicdump.
Is this what 4.10 is supposed to fix???
2). Needed my Addressbook to get email address of friend--opened the "ALL" part and there was only 15 or so addresses instead of what should have been 147 or so. Went to one of the smaller groups folders and all of the addresses were there??? How can there be more addresses in sub-category folder than in the total "All" folder?? Flipped back to the "All" folder after that just seconds later and lo and behold--all addresses were there??? This actually never went on with Panther frankly were stuff disappeared and the reappears seconds later--Is this an example of the SMART folder??? Will 4.10 fix this issue??
eep

Folks:
Looking for some thoughts or ideas on why the entire system would "quit"--perhaps due to ejecting a flash drive? That seems more serious than an addressless addressbook, although when needing an address, one might hope to find it in Addressbook, right? In Panther applications would "quit" just because it felt like it--but not the whole system. Is this "normal" now, routine?
eep

HT5172 Glad to have USB capability on my new iMac. Been in Mac world all of 2 days now. Question - I downloaded photos from a Centron flash drive and am wondering if flash drives have to be ejected the same as on a PC? Can't find how to do it. Thanks.

Been in the iMac world now all of 2 days. I'm glad to have USB capability. I downloaded photos from a Centron flash drive and now need to remove the flash drive. Do you eject flash drives on iMacs as we did on PC's? Can't find an answer in the support area. Thanks...

Yes. All external drives regardless of how they are connected must be ejected before they can be unplugged.

USB flash drive not being recognized as a startup disk?

Hi everyone, I've been searching for similar questions but haven't found one that exactly matches my experience. So, I'm going to try and explain my issue in hopes that others may be able to help.
I'm trying to create a bootable flash drive from which I can install lion, and eventually Mountain Lion when it is released onto my main hard drive. My main reason for doing this is to have a way that I can perform a clean install of the operating system. Yes, I know I am old fashioned, but sometimes I prefer clean operating system installs rather than upgrading. In any case, I have downloaded the lion setup file from the Mac app store (Install Mac OS X Lion.app) and am following the directions given on this page to do this procedure. These directions are consistent with directions found on various other sources online. Having this file saved to my hard drive, I was able to find and extract the disk image file from the package InstallESD.dmg to another folder. Once extracted, I plugged in my flash drive and attempted to use disk utility to restore the disk image to my flash drive. I selected the dmg file as my source and the flash drive as the destination. I then clicked restore and was warned that all data on the flash drive would be erased while the disk image was restored to my flash drive. I was prepared for this, so I allowed the process to continue, and it appeared to proceed with no problem. When disk utility was finished, I did a quick look at my flash drive using finder and confirmed that it did in fact appear to contain a disk image of the .dmg file. Here's where things get interesting however.
When I go to system preferences and choose startup disk, my flash drive is not listed as an optional disk from which to boot, only my hard drive ("macintosh HD"). When I restart and hold down the option key, my flash drive is not listed as a startup disk either. I know that the non-intel based macs are not capable of booting from USB, but this is certainly not my issue as I have an intel macbook pro, mid 2009 model. My flash drive is about 4 or 5 years old; it is a PNY Technologies Attaché 16 gb flash drive. I have no trouble viewing and transferring files to and from the flash drive, the only issue is that my computer seems to refuse to recognize it as a startup disk. Are there certain flash drives which do not support booting? This would normally seem more like a computer issue rather than a flash drive issue, but most people seem to have no problem doing what I'm trying to do. Unfortunately I do not have another flash drive with which to test this, and I didn't really feel like buying another flash drive just to test this out if in fact this is not a flash drive issue. I am planning to upgrade to the macbook pro retina soon which of course does not have an optical drive, which is one of the reasons I would like to get this working. Can anyone think of something else I can try? Is it more likely an issue with the macbook pro or the flash drive?
Thanks in advance for any thoughts.

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.
Mount Point : /Volumes/Mac OS X Install ESD Capacity : 16.11 GB (16,106,110,976 Bytes) Format : Mac OS Extended Available : 12.3 GB (12,303,499,264 Bytes) Owners Enabled : Yes Used : 3.8 GB (3,802,611,712 Bytes) Number of Folders : 128 Number of Files : 876

If i use a usb flash drive which is both os and windows compatible can i transfer files from my mac to a windows pc using the same usb flash drive?

if i use a usb flash drive which is mac os and windows compatible can i use it to copy files from the mac to a windows machine. i have to do some training abroad and wnat to take the files on a usb from the mac but they will only have a windows operating system available to me.

Generally, it's not the flash drive that makes it compatible, but the formatting used on it. In Disk Utility on a Mac, the format is called MS-DOS (FAT). In Windows, I believe it is called FAT32.
A USB flash drive formatted that way should be readable and writable on both Mac OS X and Windows. But you may want to try a "trial run" before relying on it for the trip.

I cannot download my pics from my flash drives into Photoshop elements 11.

I cannot dowmload my pics from my flash drives into Photoshop elements 11. Each time I try it gets to about 15% and then Photoshop crashes. It is not the flash drives as other programmes on my computer open them without a problem. Please help

Hi Neale,
That was my first thought as well, I do know that Photoshop sometimes gets a surge of shite to the brain and refuses to download the movie formats.
However after your mail I went again, through every individual pic/, about 1500 of them and yea, you were right there was one bloody movie file.
Thanks so much really appreciate your help.

My iMac won't read my flash drive

My iMac 27-inch, mid 2011, (OS X version 10.7.4) won't read my flash drives. I don't believe it is a formatting issue of the USB flash drive because the flash drives are easily read on my MacBook Air, 11-inch, late 2010 (OS X version 10.7.4). The drive occasionally will appear on the iMac, but not always, and I can't seem to figure out when it does and when it doesn't. When I use an external hard drive, it appears in the finder. Just, not the flash drives. So, I continually have to load from the flash drive to the Air and then connect to the iMac. It's kind of ridiculous. Does anyone have an idea why I can't read the flash drive on the iMac?

Could be a USB port glitch/problem - try these two troubleshooting methods:
PRAM reset:

SMC reset:

post back if it still doesn't work.
