Flash drives and sleep issues

I'm not sure if this is a Tiger problem or a G4 issue, but I'll start here.
I plug 1Gb flash drives into an Adaptec FW+USB2 card in my Quicksilver running 10.4.11 and the computer will go to sleep fine. Read on.
With a SanDisk drive when I wake up the computer it gives me an error message about the drive not having been properly removed, but the computer does wake up and the drive icon is still present and the drive appears to be okay. Apart from having to click to remove the warning message nothing seems to be the problem. Okay, I can live with that.
I do the same thing with an Imation 1Gb flash drive and the computer will not wake up. I have to use the small reset button to reboot the computer.
Both drives are FAT16 format because I use them to regularly transfer files between the Quicksilver and a Windows machine. The only difference I notice between the drives is that when I use the Imation drive a file or folder or something named "EA" briefly appears in the Finder window where all the regular files are listed. There isn't any icon and there's nothing under date, size, or kind. If I click on the EA it disappears, but reappears each time I attach the drive.

Update and answer my own question.
I re-formatted the Imation drive as FAT16 (what is was already) using disk Utility and the strange file has disappeared. Must have been something to do with the factory formatting.
I also read that the only thing to do about Flash drives and post-sleep kernal panic is to make sure you disconnect the drive before sleep. Either that or get a card that will identify a flash drive as being attached and prevent sleep, or to disable sleep mode.

Loading flash drives and CDs

I have mobile users whose use mobile accounts that do not have syncing capabilities, everything is running well apart from loading flash drives, the flash drives cannot open nor can content be saved on the flash drives. But when you restart the machine everything goes to normal, what could be the problem?
The server runs 10.5.8
Clients are running 10.6.4 on iMacs

I just downloaded pictures off of a flash drive, and half of the pictures are messed up?

I just downloaded pictures off of my flash drive and half of the picture comes out really oddly.... Example:
Does anyone know what is causing this?

Yes, forgetting the pictures, you desktop background is showing these color issues?
You need to contact Apple for diagnostic / repair. You have a hardware issue with the logic board or logic feeder cable to monitor (unlikely the monitor itself).
You just bought it and its a Retina macbook Pro correct? Never dropped or any water spills?
I was hoping that wasnt it until you said that.
while you STILL CAN see everything (even if off color) backup up ALL VITAL DATA to an external mem stick or hard drive. Documents, pics, working files, etc etc

For better speed, will a MacPro 2.8 ghz or airbook flash drive and 1.8 ghz?

For better speed, will a MacPro 2.8 ghz or airbook flash drive and 1.8 ghz?

It's going to depend on what you are doing with the machine. If what you are doing is processor intensive, then higher clock speed would give more speed. Assuming though, that the higher speed processor machine is going to have a spindle drive, then if the issue is one that is drive dependent (and a lot of things are), then the MBA will generally be faster.
If you have a machine you are replacing, I'd suggest looking at whether the applications you are now using tend to absorb lots of processor time (are you hitting 100% CPU usage regularly) or spend most of the time excercising your hard drive (drive activity is constant). If the former, the Pro is likely the better option, while if the latter the MBA would likely do better.
Of course, if price is no object just get a Pro level machine with an SSD...

Which expresscard flash drives support sleep ?

What expresscard flash drives support sleep ?

Hi patrick,
I can't give you a direct answer, but have a look at http://www.xlr8yourmac.com/feedback/express34cardreports.html in which a great many cards are commented on. THose doing so were specifically asked to mention any sleep behaviour, either good or bad, and many of them have done so.
Not all the cards are "flash" drives, of course (most, in fact are for eSata interfaces) , but it provides a very valuable compendium of information about user experiences with a variety of brands and models.
Well worth a look and may give you a few other things to ponder, too.
Cheers

Booting from a USB Flash Drive and Optimizing Performance

I know that you can boot Leopard from a USB flash drive, and I have a 16GB flash drive I'm using as a bootup disk on this 2006 MacBook I have that has a broken hard drive (it was recalled, but the recall ended in 2010).
The problem is that it's very slow. I have about 8GB of free space on it, so it can't be the VRAM being too small. The USB speed just stinks. There must be ways to optimize the OS to run off of a slow drive by accessing data as infrequently as possible. What can I do to speed this up? Should I disable hard disk sleeping? Should I use some kind of Mac tuneup/optimization tool's feature?
I plan to get an internal hard drive for it, but I'm stuck with this for a while.

Not all USB2 Flash drives are equal, in fact I bought 2 16 GB USB drives for cheap, as along side of them were even the same brand 16 GB Flash Drives just a different model, for 5 times as much!
Me was thinking how bad could they be? Well, they could be 5 times worse than other USB2 flash drives... LOL on me!
They under extremely rare occasions will Read or Write at 5 MB/s, & very often 1 MB/s...
My Buffalo Flash drives do near USB2's top speed, see some diffs...

Optimizing yours will give little benefit.
You could also do a USB2 RAID0 setup if you have enough ports.

HT1751 I have my own ITunes on my laptop. How do I take an ITunes Library from another computer, put it on a flash drive and put that library on multiple other computers?

I will be creating a new ITunes on each computer. Do I then just plug in the flash drive and copy it to the new library? Is this the same process as I created new playlists?

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.

Download and intall the Windows Support software. You can start Bootcamp Assistant again and only select the option to download the support software. Then follow the instructions to save and install the support software.
Or, manually download the support software here http://www.apple.com/support/bootcamp/downloads/.

If you subscribed to iTunes match the songs are kept in icloud. If you didn't but you did save the actual iTunes library folder which should include the music, video, etc. you should be able to just drag this file back to your machine in the same place and when you open iTunes it will give you a chance to identify the iTunes library folder.
You can test this to find out if you saved the media files or not and don't need to attach your nano to do it.
You are correct that once you connect the nano it will clear the existing files from it and sync it with the new iTunes library.
If you don't have the media files i'm not sure if/how to get them back on a windows ipod. I have everything backed up regularly because of the horror stories I have seen & heard.

I bought a used macbook air, it didn't come with the flash drive to do a factory reset. Can I download the info needed and save it to my own flash drive and then do a factory reset? If not what can I do?

If it originally shipped with Mac OS X 10.6.8 or earlier, click here, phone Apple, and order a replacement.
If it originally shipped with Mac OS X 10.7 or newer, restart it with the Option, Command, and R keys held down.

For a while now my computer has been saying " Start up disk is nearly full", however I don't have a lot of stuff saved on the computer I moved a lot to a flash drive, and all the other stuff are songs and recently saved essays for school. Help.

For a while now my computer has been saying " Start up disk is nearly full", however I don't have a lot of stuff saved on the computer I moved a lot to a flash drive, and all the other stuff are songs and recently saved essays for school. I have and frequently empty my trash can. I have researched this before and i see a lot of things that say get a external hard drive, but before I go and purchase one I want to make sure there is no other, simpler way, to solve this problem. Help Please.

You need an external drive so you can free up disk space. Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.

I exported my passwords to a flash drive, and have a new computer. How do I get those passwords moved to the NEW machine?

I exported my passwords to a flash drive, and have a new computer. How do I get those passwords moved to the NEW machine?

Firefox doesn't have an "export" feature built into it for password data.
Exactly what did you do to "export" your passwords?
Did you use this extension?
https://addons.mozilla.org/en-US/firefox/addon/password-exporter/
If so, see the screenshots on that page to see the Import function.
If you copied the two files that are used for storing passwords from the old computer to back them up, just copy those 2 files into the Profile folder on the new computer to restore them.

I have a downloaded font file for a school problem on a flash drive and I do not know how to install it into my photoshop application. Need to be walked through this as I am an older user who does not understand any of this stuff.

Fonts are handled by your operating system and installed through the respective System Control panel (Windows) or Fontbook (Mac). On Windows simply type "Fonts" in the search bar in the start menu and when you open the panel/ folder use File --> Add Font. On Mac the procedures are similar, you just need to find the Fontbook app in Applications:Utilities.
