EXtra Internal HD's Suddenly Not Recognized

For the last 5 years or so I have had two extra drives installed internally in my Quicksilver G4. Both are Maxtor N256 drives. Both have shown up on both OS9 and OSX and worked fine all this time. Now they show up on OS9 and work fine, but the icons don't even show on OSX.
Not sure what changed, but any suggestions to get them back on OSX as well would be appreciated.
Thanks from Gina

Internal sound card suddenly not recognized (laptop and desktop)

Both systems run Arch.
A week or so ago, my laptop decided to forget that it had an internal sound card... the bluetooth headset and usb sound card still seem to work just fine... but the built in card has disappeared from the system completely. This morning, I was listening to shoutcast on my desktop when I left the room... I come back to complete silence and vlc (which had been playin shoutcast) was no longer running. So, I started to play some local music via Rhythmbox... no sound... I open my mixer, the internal sound card is gone! The only instance I can seem to find it is if I run Alsamixer via the commandline (have not tested this on the laptop yet, was planning to troubleshoot that before the end of the week). What information do you guys need to help me figure out why my soundcards have suddently gained amnesia? again, ALL external cards on both systems work just fine (listening to shoutcast on a USB sound card at this very moment on the desktop)...

The card is still not readable directly on the computer? Can you write to the card and read from it with the computer? What about with another device?
You need to determine if the problem is the BlackBerry or the card. If you can read the card or write to it with another device, that suggests the card. You should also try a known good card in the BlackBerry.
If the card is the problem, you could try repairing and recovering files with the computer first, and then format the card and test. If the problem continues or returns, get a new card.

Ipod shuffle 2nd gen suddenly not recognized by itunes, any ideas?

My 2nd gen shuffle is suddenly not recognized by itunes, all troubleshooting done per apple support, ie make sure cords plugged firmly, try all usb ports, try different cord etc... any ideas?

Hello,
I had a similar problem. I posted my problem in this link:

Would you read that and see if it sounds like something you're experiencing? If so maybe we can both scream for help on here at the same time, and get some answers!

Windows PC suddenly not recognizing iPhone. Recognizes another iPhone just fine. USB works until operating system in PC (XP) loads. Any clues out there?

Windows suddenly not recognizing iPhone, yet recognizes another iPhone fine (sees in iTunes, etc.) USB appears to be fine - passes electrical to iPhone until operating system (XP) boots, and then "disconnects". I've gone through all of Apples suggestions for troubleshooting - including msconfig. Same result - quick double "bong" tone and no connectivity to iTunes. Versions are all up-to-date.
Any suggestions out there?

How did you get the VMWare sync to work? I hate Apple at this point.

try resetting your phone by turning it off and back on again. The servers may still be having a hard time keeping up, so you may just need to wait a little while and try again.

External Hard Drive suddenly not recognized

I have a WD 500GB external hard drive that I use to back up my data. I only have one hard drive as I'm currently living abroad and couldn't bring a 2nd with me.
I plugged in my external last night to back up my MacBook Pro and it backed everything up. I even went into Time Machine to go back and restore a file or two and that worked without problem. I have been using this drive for about a year to back up everything on my Mac and, although sensitive, it seems to work okay.
I plugged it in this morning and nothing. My Mac will not recognize that the drive is not plugged in in Time Machine or in Finder. If I go to Apple Logo > About This Mac > More Info... > Storage tab, it just shows my internal hard drive and my CD/DVD drive. If I click on Disk Utility with the drive plugged in, it shows my Hard Drive (Macintosh HD) with two icons, one inset below the other and both in black font, and then my external hard drive has two underneath, but only the top one is black font - the one underneath is greyed out.
It goes like this:
250.06 GB Hitachi...
     Macintosh HD
500.08 GB WD My Passport
     Time Machine Backups (greyed out)
Superdrive (greyed out)
When I clicked on the 500GB one and told it to repair/verify it said the disk was working fine. I tried unplugging and replugging in the drive (it is not recognized in Finder so I could not properly eject the disk). I restarted my Mac with it unplugged and plugged it in afterward and nothing.
The HD itself is working, the light is blinking (not solid) and I can feel the hard drive spinning, but I'm at a loss as to what to do to get my Mac to recognize it again.
Any suggestions would be helpful.
Thank you!

I also wanted to add, when I click on the greyed out Time Machine hard drive that's listed and then click "Info", this is what it says:

USB suddenly not recognizing devices

Hello,
I have a problem.
My MacBook Pro suddenly stopped recognizing usb devices. This morning everything was working fine, but for some reason a couple of hours later it's not working anymore.
I can connect my phone via usb and it's reloading the battery. I can't get into my files though, while I was able to do that this morning.
My MaKey MaKey also gets power and the lights flash. I can use it to play an online game. It isn't being recognized as an usb device though, and I can't upload new code to it.
I haven't changed anything between the point it was working and the point it is not working anymore.
The only change is that I've tried to connect my MaKey MaKey and upload code to it. But that didn't work, because it said there was nothing connected to my usb port. That's how I found out that it was broken.
I have tried resetting my PRAM and SMC but it both didn't help.

Thanks for your answer.
I already tried the things listed in the link you sent, but unfortunately they didn't work.
However, a few hours after I posted my question things started working again. I can connect my phone again, and the MaKey MaKey shows up in the USB list if you go to About this Mac. Still can't upload anything to it though.
But I guess my problem is solved.

My internal hard drive is not recognized by the leopard installer disk

i just got my leopard delivered this morning, and have just put it in, every thing is going well, until it comes to the screen where you select the hard drive you want to install leopard on, and my internal hard drive does not show up, however other drives do (like my external hard drives and usb sticks).
really hope someone can help! thanks

I am having the same problem with my MBP with Leopard. I get a flashing question mark on startup, and have repaired/permissions and my startup disk doesn't show up. I reset PRAM, and then ran permissions again to no avail. If it really is Spotlight just indexing, Apple should tell us that in their technical documents. If anyone has any other solutions, that would be appreciated.

Computer suddenly not recognizing device

My computer is not recognizing my iPhone 5 when I plug it in to transfer purchases and update. I have had the phone for awhile and it was working just fine.

Great! It's not the first thing you think of, but my philosophy is "when in doubt, reboot." What probably happened is the AppleMobileDeviceService crashed. This is the easiest way to restart it.

Z2 suddenly Not recognizing the SIM and no signal.

When I'm using data for straight for like 2 or 3 hours, the phone suddenly stops recognizing the SIM and it shows no coverage. I have to restart the phone all the time :/

MuVo TX suddenly not recogni

Hello All I'm hoping someone here has an idea. I just tried by MuVo Tx Fm on my WindowsXP computer for the first time after loading the latest drivers. XP deli'vers a message saying the USB device has failed and is nto recognized. When I click on the message, it says no drivers are installed (when I insert my old MuVo CD, . I get a message saying a newer version of the driver is installed,and it terminates) I then plugged it into my Win98 comptuer (the one I've been using with it), and the players does not show up in device manager. The player IS working. I can listen to anything that's already loaded. When I plug it into either computer, I see the connection image on the player LCD screen , although the screen is NOT lit up. Since the player is not recognized by either computer, I cannot upload files (music or otherwise).Any ideas Thanks. Anthony Giorgianni

I got mine woking. This what I did.
First I did not followed the recovery instructions.
If you installed the Device Recovery Mode drivers uninstal and reboot pc.
I did downloaded the MStorage_PCDRV_LB__07_00_250.exe (link is in recovery sticky) just to have the latest drivers.
Plug the MuVo TX FM to your pc usb.
When the install wizards appears do nothing.
Unplug MuVo.
Close wizard.
Plug MuVo again to your pc usb.
Run the firmware update (Go to download section to get it). Gi've it a minute (more or less).
The upgrade process will do something, I don't know what it is that recognizes the Muvo (The Muvo turns on).
Follow instruction on screen.
BTW your Muvo will be formated, keep this in mind if you have important info in it.
I hope this hel
ps.
I went thru a lot of trial and error so I may have missed a step.Message Edited by jibaro009 on 0-09-2006 06:22 PM

Windows suddenly not recognizing iPod Shuffle - drive letter conflict

If you're having troubles with your PC not recognizing your Shuffle even though it used to recognize it in the past, this is just something else to consider (sorry if it's already been covered):
When I originally connected my Shuffle to my laptop on my home network, it was recognized immediately, and my WinXP OS assigned it the drive letter "I". Later, with the Shuffle no longer connected to the laptop, I was setting up my home network, and I mapped one of my shared network locations to the "I" drive letter on my laptop. The next time I plugged my Shuffle in, Windows would not recognize it. I proceeded to plug it into both of the other computers on my home network, and it was recognized immediately on both of them. So I then went back to the original laptop, disconnected the network drive mapping I had set up for "I". Once I did that, when I plugged my Shuffle back in, the Shuffle was again being recognized immediately (not surprisingly, still as drive letter "I"). In short, Windows has a memory of drive mappings made in the past, and sometimes this can produce unexpected or unwanted behavior (I would have expected my Shuffle to automatically be assigned the next open drive letter, but alas, that was not the case in my experience).
To minimize the possibility of running into this problem again (in case I do more network drive mapping in the future), I used the Disk Management utility in WinXP to change/force the Shuffle's drive letter on my laptop to be "Z" (right click on My Computer and choose Manage, then look for the Disk Management module - you probably will need Admin rights to do this, but I haven't confirmed that).
PC Windows XP Pro

Had this happening too, had a very old cable, tried a new cable and it worked great. My ipod was showing up in itunes, but not in windows (or in device manager). When I tried to use the utility to copy files from my ipod to my hard drive I couldn't do it (wonderful utility getsharepod.com). The new cable solved the problem!

Itunes all of a sudden not recognizing ipod connection

4G iPod suddenly not recognized by Windows but firewire charges it.

All of a sudden today, my 4G iPod isn't recognized by either of my 2 computers through any firewire port. When connected, it charges and the charging icon blinks, but the iPod screen does not say "do not disconnect" like it's supposed to. It just remains in the regular menu mode (fully functional and playable through earphones). iTunes reports "No iPod Connected." My PCs do not see it as a drive, disk or an iPod. It was fine earlier today and nothing abnormal occurred to the iPod or to my computers.
One of my PCs is running Windows XP Pro and the other is running XP Media Center Edition.
So far I have:
-reset the iPod 10+ times
-tried the internal diagnostics (all passed)
-putting it in "disk mode"
-rebooted my PCs numerous times
-run iPod Updater to see if I was able to update or restore ( software just says "plug in an iPod to update it")
-tried several different ports on my PCs and several different iPod cables (with and without a dock)
-tried ending and restarting iPodService and iTunesHelper in Task Manager
-kicked myself for not extending the service plan with Apple
I don't think that there is a problem with the iPod port itself because it is able to charge through the firewire and AC adapter.
Can someone please offer a suggestion? I really don't have hundreds of dollars to pay for repair or buy a new one. Any help would be greatly appreciated. Thank you.
PC Windows XP Pro

OK I fixed it. I'm not sure how or why it worked but it did. Here are the steps I used if it helps anyone:
1. Reset charged iPod while not connected to machine.
2. Put the iPod in Disk Mode.
3. Connected it to the USB 2 port
4. Windows saw it but itunes said it needed to be restored and could not see any of my music.
5. Installed Anapod
6. Anapod saw the iPod, and corrupted music files.
7. Using Anapod's Manager Options (right click on tray)/ ipod devices/Recover Missing Tracks, the music was quickly restored and itunes was able to see the whole library
8.Using Copypod, I transferred all the music on the ipod to my computer.
9. Restored the ipod with the latest update utility
10. Transferred my music back to the ipod
I hope this helps someone.

Zen Xtra Nomad Jukebox suddenly not recognized by Windows XP Netbook

I'm desperately struggling to get my Creative Zen Xtra Nomad Jukebox MP3 player (version .03.02) to be recognized by my computer. (My background is I'm about 4 hours south of my home, temporarily helping my exwife who is slowly dyiing of cancer... [URL"http://www.youtube.com/watch?v=wA67hNO3H4"]http://www.youtube.com/watch?v=wA67hNO3H4[/url] I have two laptops with me, one with XP (and the other rarely used here with Vista.) My main computer, a Dell Desktop running XP, is back at home with most everything else as I live out of a suitcase and do the best I can.... 'nuf said for my situation)
About 3 weeks ago, I hooked my Creative mp3 player up to my MSI netbook, (windows xp and recently updated with all microsoft updates) and noted that the MP3 player was not being recognized by the computer. When plugged into the USB, my computer gave a 'chirp' and would look for hardware for the player, but ultimately it couldn't find it. The DEVICE page of the SYSTEM menu had the Jukebox listed with the nefarious yellow question mark. Though I don't have a CD drive on this computer, I had a portable drive with most of my software with previousl loaded software archived there, including the installation disc for my MP3 player; but none of the drivers or software that I loaded would make a difference. I download all sorts of drivers & firmware updates from the CREATIVE web site, nothing changed. I would remove all the creative software, reload, reload software, hook up the MP3 player, and.... it would recognize the Nomad player but have no way to incorporate drivers for it's use. Even as I directed it to the original 'CD' copied onto my netbook's desktop, my Windows XP with service pack 3 just couldn't do more than let me know that it couldn't quite recognize the player other than identifying what it was.. I could uninstall the device, the drivers; all to no avail.
My incorrect guess at the time was that something internal to the mp3 player was broken and though I was lucky that it still worked as a player without any issues, I just had no way to access the 30Gb of books & lectures. Nor would the Creative Media Source work with it, as it felt that the player was not even hooked up to the computer. So,I bought a new 'used' identical model on ebay, except that the seller had upgraded the firmware and the harddrive. Once I got the new player, it's too, would not be recognized by my MSI netbook. (though it works on the laptop I have running vista).
Last week I gratefully went home for one day to check my mail and attend to a few matters, and upon hooking my original MP3 player to my main desktop, my original MP3 player immedately docked to my computer and was working as it always had?
Now, atleast, I knew the MP3. player was working and functionally intact, and the challenge was completely computer software issues on my netbook, possibly due to some service pack upgrade or the sort.
I've spent several hours, reviewing all sorts of fixes and maneuvers; from blogs and tech support pages, though none made any difference as I changed various settings or softwares on my netbook. I saw lots about Vista not supporting my old firmware (which isn't an issue as my Netbook is XP.. I also saw that Windows Media player might have been the problem, and reverted to WMP 9, then to 0, though stlll no change.
I have never turned to a tech support board before, but I'm very much in need of assistance right now. Please, if you think you can guide me, I would appreciate it.
~Stuart

Thanks for the reply. I sure wish I had a better understanding of this. I will request one more piece of invaluable knowledge from you! My old zen & windows xp computer hum in awesome performance again. Unfortunately, since I thought my old zen was broken, I'm now with this new beast, with the updated firmware 2.0.03. From what I previously read on Boards and Forum pages, this device shouldn't be connected to my XP computer while I'm still using my OLD zen with old firmware. As you mention in the above note, I connect this 'new' Zen to my Vista computer, & it immedately goes into docking mode. I tried loading the newest firmware available for my device (though it doesn't list vista as compatable), and of course, when the mediasource version 3.30.2 loads, it doesn't have a clue that my zen is connected. Only WMP version seems to pay attention, which may not be that bad. But once I was up & running in WMP, I couldn''t seem to create playlists and or even clearly get it to load the Audio Lectures that I have onto it. So, Wise, All Knowing CREATIVE Wizard, any suggestions what I do? Delete WMP? I will hope never to bother you again, once this is solved!!!
But I am tremendously grateful for the assistance. I only spent about an hour in WMP accomplishing nothing, before I realized I should just turn to you, admit my defeat, and hope for insight and practical advice!!!!!
Thanks!!!
