ESATA Wiebetech external HD on ExpressCard34 not recognized

I have a 1st gen MBP running Leopard 10.5.1. With OS 10.4, my Wiebetech eSATA HD was working thru the ExpCard34 slot. I did a clean install of OS 10.5.1, and the drive is no longer recognized. If I connect the Wiebetech HD with USB, it does get recognized and the Wiebetech icon appears on the desktop. So it's not the HD itself, I guess. Does Leopard have an issue recognizing the ExpCard34, or is there something I need to do in Unix to get it recognized? I guess it could be a failure of the Slot itself, the Card, or the cable, but that seems very coincidental. At the moment, I don't have an extra cable or card to test. Can anyone help? Thanks.

Well, that is a far as I've seen anyone get so far. I have a similar issue, maybe you can help me. I am using Windows XP Pro. I have a newly installed Airport Extreme (about a week) and I’ve never been able to see the network drive on this router. In the “Airport Utility” I can see the drive, but I can not see it on my PC or in the “Airport Base Station Agent” in my system tray. When I click on the “Airport Base Station Agent” in my system tray the only option that I get is “Open Airport Disk Preferences”. When I open that, I have two options (both are checked)
1. Automatically Discover Airport Disks
2. 2. Show AirPort Disks icon in the system tray.
Further down in this window there appears to be a place where disks should be listed, but I don’t have any listed there. I know this disk works, I can plug it directly into my PC and read and write to it with no issue.
Oh somebody please help me !
Thanks,
Dennis

My external hard drive is not recognized by my computer. I used it earlier and it was fine however my computer froze and I unplugged my hard drive without properly ejecting it. Now when I plug it in nothing pops up. I've tried on three different computers and no luck. I hope this is fixable! Please help.

External hard drive is not recognized after attempt to format

I just got a new macbook and couldn't use my external hard drive because it was formatted on a PC and only allowed me to read the data. I backed up the data on the 250gb hd and then used Disk Utility to erase the hd and format it as "Mac OS extended (journaled)." After beginning, Disk Utility stopped working and showed up as "not responding" in the Activity Monitor.
Now the hd does not show up on the desktop and can only be seen in Disk Utility. If I try to erase again or partition the hd the utility stops responding. If I try to zero out the drive it continues to say "preparing to zero" indefinately. Now the hd is also not recognized by windows except in the windows disk utility, but it does not even give the option of formatting/initializing it, so that is not an option.
Has anyone ever seen anything like this before, or have any idea of something that I haven't tried yet. I really want to get the drive working and have exhausted all the ideas I can come up with. The internet has not provided too many ideas either.
Thanks so much for your help.
Black MacBook Mac OS X (10.4.6)

I have crazy solution to format it to FAT 32, it work a couple times on my several MAxtor, and Western Digital HD. But this is the last resort and if you are not handy and familiar, don't do it.
It happen on my external HD, so I crack the enclosure open, pulled the HD out and attached it as internal HD on a PC after adjusting the jumper to master and make sure no other HD attached to the motherboard. Make sure the motherboard detected (you can see it from bios menu).
Insert a bootable installer disk before XP ('98, ME, or 2000), and start from there until a promt comes, and type fdisk and you delete the old partition and create a new partition and restart once using the disk still and format it using FAT 32.
After that you put it back to the enclosure, and mount it to MacBook as a new HD with default factory format.
If you don't have the installer disk, this might help :
http://www.bootdisk.com/
But if your maxtor still under warranty better talk to them first and they might willing to reformat it for you.
Hope this help your external back and let you use it on your MacBook.

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:

My external USB drive is not recognized by Win XP

Hi!
I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
Thanks for any help!

Hi Anders and welcome to Discussions,
I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
Yes it will !!
Although with the BootCamp 3.0 Drivers (from the OSX Snow Leopard DVD) and the 3.1 Driver update (downloadable) Apple has introduced read-access to HFS+ partitions from Windows this feature seems to have some serious problems for some people.
Personally I see this feature as "experimental" at the moment.
XP itself knows nothing and therefor can not use/see HFS+ partitions and GPT (GUID partition table) harddisks.
You might wanna have a look (or buy) at MacDrive http://www.mediafour.com/products/macdrive/ which right now is the better solution.
Thanks for any help!

MSI UBO-30 External Slim Bluray Drive not recognized under Windows 8.1

Hi, does anyone here have MSI UBO-30? It is an external bluray drive from MSI. For some reason the drive is not recognized under windows 8.1 64 bit (it just says USB device not recognized). But works fine if plugged into Windows 7 machine. Anyone encounter the same issue?

Try upgrading your usb 3.0 drivers on your system. That worked with My GS70 Stealth Pro...

My external hard drive is not recognized

I have the apple external disk drive. I have used it numerous times. I just plugged it in and the computer is not recognizing it. I have tried both USB ports. How can I fix this?

A: USB desktop or 2.5" port powered?
B: did you just install mavericks
C: DOES IT show in disk utility?
Can you confirm it on another Mac?
Apple doesnt make HD, what HD is it marked as?
Likely its a dead SATA bridge card, a very very common problem with USB and external HD

External keyboard and mouse not recognized after waking from sleep

This started happening all of a sudden. It was working fine before that. When I disconnect the power cable, keyboard, and then connect them back, its not recognized. To make it recognize the keyboard and mouse, I have to logout and login or restart the laptop. I looked at this related post, but the PRAM reset fix did not work for me : http://forums.macrumors.com/showthread.php?t=870482
Any idea how to fix it?
OS version: 10.9.2
MacBook Pro 13-inch Mid 2012
Processor 2.9 GHz Intrel Core i7
Memory 16GB 1600 MHz DDR3

I have a similar problem on our G3 iBook with Panther. Most of the keys don't work, and of the four or five that do, they print only gibberish.
For a while I had control of the "C" key, and I was able to start from the Installation CD-ROM. I ran Disk Utility. It found and repaired a whole bunch of permissions and reported no problem with the hard disk. But I still cannot use the keys, and since then I've lost the use of the "C" also.
Because I cannot use the keyboard, I cannot type in my administrator's password, and for that reason I cannot use System Preferences to start from the Installation CD-ROM. I did not see the Hardware Test on the CD-ROM, but it sounds interesting.
Any ideas on how to get back to the CD-ROM when my keyboard doesn't work?

External Pioneer 116 Burner Not Recognized

My Pioneer 116 (Firewire) in a Bytecc case is now not recognized. Anyone else having difficulties? Printers work, don't see why this should have issues, but now I'm stuck using the internal Matshita, which I really don't want to use.

Same problem with my Pioneer DVR-111D, tried the suggestion of switching from Firewire to USB, it works. Burned CD in iTunes, OK. Have not tried to burn DVD in The Burn Folder (my homemade iMovies). However, I did make 4 nice coasters last night until I found this post. OS 10.6 needs to work with Firewire connection.

To backup my existing environment I bought Seagate Free Agent GoFlex 500GB for PC and Mac. USB 3.0 but backward comaptible to USB 2.0 which is what my laptop is. The system requirements included support for 10.4.11. I attached the drive to my lap top and used disk utility to format to Mac Extended OS (journaled). It recognized the drive immediately.
I used SuperDuper 2.6.4 to copy all files to the external drive. It seemed to copy just fine. It said it made the drive bootable. TO test it, I shutdown the system and started it back up with the option key pressed, but it only gave me my original HD as a choice to boot from. When the system came up, it didn't recognize the external drive. I unplugged the drive and re attached it and it seemed to recognize it, I trued to reboot again and it doesn't recognize the hard drive on reboot. Only when I un attach and reattach it.
Any ideas?
Thanks in advance.

I haven't forgotten, it just takes forever to get to a result when backing up an entire system.
So here's what I did. I agree with this idea:

I suspect StartupDisk is seeing a nicely mounted drive connected in a bootable interface (USB) with all the needed files (palced there by SuperDuper). However, what it doesn't know if that drive isn't really accessible until the computer has properly booted because the chipset doesn't work without full system support. This is not at all unusual in external drives. Many years ago you really has to insist upon having an Oxford chipset in an enclosure to guarantee booting, but for general backup use any chipset was fine.

I moved everything from the Lacie to the SEaget - at least is it will be useful for something!
Erased the Lacie, partitioned it to 2 partitions.
Formnatted the partition GUID as suggested. I had named the partition for the backup something cutre like 10.4.11 OS clone.
Used Disk Utility>Restore to backup/clone the environment.
During the backup, it renamed the partition Macintosh HD, which was encouraging. After waiting a very long time for the backup, I was able to try to test booting from it and received many diagnostic errors including permission type errors, some of the files in /etc did not beloing to root. I have a couple of things I am going to try but thought I'd throw it out here since you guys have kept me pointed in the right direction.
Any more ideas as to why the drive won' t boot? Did I not give the partition enough space? Is it the chipset thing?

External harddrive in network not recognized by windows XP

External USB Hard Drive not recognized on iMac HELP!!

I am currently using a i5 iMac running Lion 10.7.5
I have recently partitioned a Verbatim USB external hard drive and uploaded all my footage from a wedding. This was done with no problems and the QT videos could be opened from the hard drive.
A few weeks later, the hard drive does not show up in my finder. BUT it is recognized in disk utility. Here is a screen shot;
So first I ran "Verify" and it told me to repair disk. After clicking on Repair, I got this;
It is giving me the error message "Invalid B-Tree node"
Here is more info on the hard drive;

Can someone give me a step by step on how to get the hard drive working again? It would mean the world to me as this footage is priceless and irreplaceable.
OR can you refer me to someone (Geek Squad? Apple Store?) that might be able to help me out?
Thanks in advance!

The error message invalid b-tree node size indicates that the directory on the disk is corrupt. The way that it can be repaired is to reformat as disk utiltiy says.
It is recommended that the data be backed up first before either of this solution are done.
Since it is not be recognized by the sytem at all it does sound like you can back it up now.
Do you have a backup?
If you don't there is every chance you may lose all your data.
You can check to see if a data recovery service can recover any data for you. If you go that route you are looking at spending $$$$
