Mac won't recognize CD and Zip Drive

I have a Beige g3 MiniTower 400mhz running 9.2.2 with
built in Apple CD and Zip Drive. Overnight, the
machine no longer recongnizes either drive. The
extensions are there, and checked. I upgraded from
9.2.1 to 9.2.2 - no change. I downloaded the latest
Iomega drivers and tools - no change. Any
suggestions as to how I fix this problem - where can
I download the drivers for these drives so I can
replace them? I bought the machine used and do not
have any original OS install disks. Also, if I hook
up an external SCSI Zip drive to the external SCSI
port, the machine hangs and will not boot - any idea
why it would do that? any help you could give would
be appreciated - thanks - Charlie Mac

Thanks, all, for the idea about the battery, but it didn't work - replaced it last night and still have the problem - someone else suggested it might be a hardware problem - bad ATA controller cable or whatever, so I'll crack the case and see what I can find - I was able to hook up the external SCSI Zip Drive and an external USD CD, so I can limp along with those until I get this figured out - thanks - Charlie Mac

MY MAC WON'T RECOGNIZE MY EXTERNAL HARD DRIVE

Hello. I'm the main user in my mac mini so I was trying to avoid my girlfriend from using the external drive, so looking around signed with my girlfriend user, I controled click the external HD icon in the finder and click on information, then I saw an option that I thought could give me the chance to avoid her from looking around at the external drive with her user, after several times trying to do so with my name and my password (I'm supossed to be de administrator) it kept telling me that I was not a sistem administrator. the external drive kept working but I ejected it to see if what I did would work (the other user not beeing able to see into my external HD) but my surprise is that no longer my mac recognizes the external HD. Do you have any clues on what is going on? It can be somethig with the permissions because looking at it with disk utilities it says that no owner activated neither S.M.A.R.T. Can anyone help me?
thank you

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

G3 won't recognize Internal IDE hard drive!

I'm trying to resuscitate a B&W G3 mac (rev. 1) from a Goodwill, and I've gotten it to boot from a G3 installation CD with OS 8 on it, but it won't recognize the sole 27GB IBM ATA/IDE drive I have plugged into it. (The previous owner held onto the mac's original drive.) My drive used to be the master drive in my Quicksilver G4. (I erased and reformatted the drive prior to moving it out of the G4.) I've tried adjusting the drive's jumper configurations, but no matter what, the Mac won't recognize the drive & allow the OS to be installed on it.
Why is this happening? Is this some kind of logic board failure? Will I need to reformat my drive in some special way? Will I see results if I invest in a ATA-133/100 PCI controller card and plug my drive in there?
B&W G3 300Mhz Mac OS 8.6 or Earlier 256MB RAM

When the drive was in the G4, you formatted it as a Mac OS Extended (HFS+) volume, which is imperative with a drive of that size. If formatted as a Mac OS Standard (HFS) volume, the drive's storage capacity would be squandered with small files parked in excessively oversized allocation blocks. When you referred to using a G3 CD with OS 8, do you mean OS 8, 8.1, or 8.5.1? A CD with OS 8.0 would pre-date the beige G3s, and OS 8.0 doesn't provide support for HFS+ volumes. If the CD has "G3" printed on it and contains OS 8.1, it's intended for use with a beige G3, because the earliest B&W G3s shipped with OS 8.5.1. If your boot CD has OS 8.5.1, then the problem is undoubtedly related to the Rev. 1 IDE controller's lack of support for large drives. A much-smaller IDE (4 - 8 GBs) drive or a Mac-compatible ATA controller card will solve the problem.

My notebook won't recognize my external hard drive

Mac won't recognize my password to let me download anything

I recently downgraded from Yosemite Beta to Mountain Lion and now my mac won't recognize my login credentials. Curious thing is it does recognize them to let me login at startup. But it won't let me download anything because it says my password is wrong. I changed the password and again it recognized it to let me login but not to download anything. What's going on?

Where are you trying to download from? Apple ID password?

MacBook Air won't recognize iOmega External Hard Drive

I just bought my macbook air and I wanted to transfer my data over from my old MacBook. The MacBook died so I was using my backup. The problem is that the Air won't recognize the ext hard drive. I connected the ext hard drive to my AirPort Extreme for the migration assistant but I keep getting a connection failed message. I tried plugging in the drive to the air directly using USB but it won't recognize it at all. The drive won't mount. The drive begins spinning and the light is on so the drive does work. It always worked with my old MacBook. I did alway connect it with FireWire so could that cause a problem since I have to connect it with USB to the Air?

I had a similar issue with mine but it was because I tried to connect to an external drive that was already connected to my iMac via FW800. When I disconnected the FW cable and plugged in the USB, everything worked perfectly.

i tried to get the installation disc for the camcorder but mac wont' recognize it becaue it is windows based i guess.
i just bought the camcorder a few months ago and when my computer crashed thought i'm finally getting a mac...it's been a costly venture which has resulted in more frustration than before my pc.
now the things i want to use with my mac that i thought would be even simpler...are not even useable...

That camera shoots H.264 in an .avi wrapper.
You will have to transfer the files via the Finder.
Get a free copy of MPEG Streamclip and convert them to QuickTime .mov using the H.264 codec if you are presumably editing in iMovie.
Note that your list of video codecs won't look like mine as I have Final Cut Pro, but H.264 is definitely an option for you.

If you've forgotten the passcode to unlock your iPad then there are instructions on this page for how to reset the iPad (your iPad doesn't need to be connected to the internet) : http://support.apple.com/kb/HT1212
If your computer's iTunes isnt recognising the iPad when you connect it then have you got a recent version of iTunes installed on your computer ? There are also troubleshooting pages for a device not showing in iTunes on these pages :

After transferring music to new Mac, Mac won't recognize iPod

I just recently transferred my music from a PC to a new Powerbook G4 using my iPod in disk mode. I erased everything on my iPod, then loaded it with music in disc mode to put on my new computer. But now, I need to erase the stuff on there in disc mode so I can put it back in the normal mode.
Just when I thought I was figuring it out, my Mac won't recognize my iPod. Do I need to reformat it for a Mac since I was using it with a PC? Be gentle, I'm new to Macs and don't know the lingo or my way around very well yet.

Exactly what steps did you follow?
1. what do I do with original iTunes folder?
It's on your old computer.
What do you want to do with it?
2. how do I get iTunes to read/ingest playlist and songs?
If you copied the entire /Music/iTunes/ folder from old computer to /Music/ on new computer then you simply need to open iTunes.
Since it is the exact same library, everything will be there as it was on old computer.

Have you just tried repairing with Disk Utility?
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

Hi and welcome to Apple Discussions,
Did you get the flash drive from a reliable source. There are some available on the net that show a large capacity but are only 512 mb. or 1 gb. drives that have been altered to display a much larger capacity.
Good luck,
Alan
