External drive stuck in limbo - no errors, data intact, still won't mount?

Background story:
-I had an external enclosure with two drives (one Hitachi, one WD, both SATA) running seperately inside as storage. Things were good.
One day something went wrong, because I turned it on and weird clicking could be heard and the drives wouldn't mount. I tried them in another enclosure I had lying around (that was apparently borked too), panicked and brought the drives to a data recovery center.
The next day, the recovery center called me to let me know that they were able to read data off both drives and that scans showed no problems. I picked them up (and since I was already in Akihabara I bought the supplies needed to build a RAID5 bay that I've been planning for a while), got a new enclosure for them, went home.
I put both drives in the new enclosure and flipped the switch: the Hitatchi mounts just fine, but the WD doesn't mount. The drive and its partition show up in Disk Utility, but the partition name is grayed out. When I click the 'Mount' button, I get the following message:
*Mount Failed*
The disk "Photos" could not be mounted.
Try running First Aid on the disk and then retry mounting.
I then click "Verify Disk" and the following comes up:
*Verifying Volume "Photos"*
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
+The volume Photos appears to be OK.+
The plot thickens! After some fiddling around I discover that I can make a disk image out of this unmounted partition and proceed to copy it into my shiny new 2.7TB RAID5 unit. A few hours later, I have a 600GB .dmg, which pretty much corresponds to how much data I had on that drive. When I try to mount it?
+The following disk images failed to mount: Photos.dmg (no mountable file systems)+
I'm really at a loss, here. I'd rather not pay a data center to back everything up and I suppose I could bring it all to the Apple Store, but again that seems like a waste of time. Is there any way I can get my computer to mount this drive?

Sadly, I offer no help, only commiseration and another problem. I too had the big checkmark, for similar reasons. If you want, see my posts in iPod usage-"Restore won't restore." However, I did get past the checkmark eventually (I think by running update several more times, then saying no to the last one).
Now I have a new dilemma. It seems mounted. I see it in iTunes. But when I drag songs to it, they just disappear! Poof.
I just ran Disk Utility, which also "sees" it but and it tells me, the disk ipod cannot be unmounted. This is getting very old.

Using Disc Utility to copy my hard drive to a brand new external drive and am having the error "Unable to create...(Cannot allocate memory)".

I'm not very tech savvy but am trying my best to use Disc Utility to copy my hard drive to a brand new external drive and am having the error "Unable to create...(Cannot allocate memory)".
Last night no problems, woke this morning and it was freezing so I forced a restart and got the grey screen with the folder and question mark. Ran off to best buy to get an external drive... Please help! Thank you!

I have done both. When I hold down the "C" key it pauses for a few seconds while the cd spins and then the flashing folder icon appears.
Could be you have the wrong cd/dvd. The mac will only boot a supported cd/dvd for your machine. The flashing question mark indicdates your machine could not find a valid os.
When I hold down the "option" key for the startup manager the cursor comes up and moves but the actually manager doesn't come up no matter how long I leave the laptop on.
Not sure. Could be your machine does not support the startup manager. You would think the machine would ignore the key.
Where did you get the dvd? What is the number on the DVD?
What machine do you have anyway?

While trying to setup a time capsule backup to my MyBookLive external drive, I got the following error message: The network backup disk does not support the required AFP features. What's up with this?

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

Those look alot like file names and not infection names. I don't find any reference to anything like that on Norton or VirusTotal. Since you said these were Trojans, I would expect to see "Trojan" as part of the infection name.
".jar" files are executable Java applets. The random alpha-numerics would seem to indicate a cache file, likely from a browser with Java enabled. And we all know what ".zip" means.
Worst case is that you had Java enabled in a browser and were infected by one of the late variants of the Flashback Trojan over a year ago or one of a couple of other attacks using the same vulnerability but targetted against a small number of political sympathizers. Much more probable is that thes were Windows only Trojans. Hopefully you have a fully up-to-date OS X, including Java, and have disabled Java in all your browsers by now.

Make a second copy on import to external drive and copy the file by date

In earlier versions I made second copies of files imported to an external hard drive. The files would import and automatically create a capture date file folder in the same manner as importing by date to the primary internal drive. At some point this feature seems to have gone away and now I get a folder on the external drive: p:\\pictures\2014\Imported on Tuesday, April 22, 2014. What I would like is: p:\\pictures\2014\2014-04-22
Is there anyway to force this to happen? I really hate having to manually move lots of files and create folders to keep the system I have had for years that organizes my files by date of capture on both the primary and backup drives.

Short answer: No. That is the way it is.
Why? The Make Second Copy during Import is designed to be a backup of your memory card processes-not a back up of your files as you store them on disk. It is intended to be a transient copy that allows you an immediate backup until such time as a File System Level backup can be performed, allowing you to have two copies so that you can reformat your memory cards.
I agree it would be nice if the folder storage strategy was duplicated for the backup as it is created for the import but that is not something you can set the program to do currently. I remember it behaving differently versions ago but do not recall exactly how it used to work.

Trying to move pictures to an external drive and I get an error -50 message

Can't move pictures from Dropbox to my external HD. I get an error message -50.

Can you copy the files from drop box to your desktop? (not move, but copy)
Can you copy other files to your external HD? (a file not in your dropbox folder)
Is it all files in drop box? or just some files?

Upgrading my intel iMac to internal SSD and running 1TB external drive from firewire 800 for mass storage while still using a second external drive for backups...my goal-speed with a SSD, to still have 1TB of room for everything i have now..possible?

I seem to kill HD's every two years...the last two i've installed were WD Caviar Black 1TB 7200rpm 3.5" drives. The speed gains over stock drives have been remarkable. I don't blame the drives for the failures, my machines are up and running 16 hours a day, every day, year round. They die from 'mileage' so to speak...i assume...there's no viral acvtivity or questionable downloads to gunk things up...just lots of work.
I have my third new drive ready to install in my intel based iMac...but i've had a thought...I want to install a SSD in my iMac for the speed gain (and recent price drops)...for standard storage i want to use this new WD Caviar Black 1TB in an external drive bay and connect via firewire 800 for storing everything except the OS and my most commonly used software...am i crazy? will the firewire 800 external drive negate the speed gained with an internal SSD??
I have four iMacs in my office, and one at home. I buy second hand and install new drives and boost memory. I'm going to do this on my 'home' machine...if it works out well i want to upgrade the other three this way...but first i need to know if i'm just dreaming, or will it really make a difference? or even possible??
Thanks!

The SSD gives great bootup and Application launch speed. I think it also speeds up the video rendering a bit, I do all that on the SSD and then move the finished project to the external drives. As far as the speed for the external drives they are quick enough for viewing video and the file transfer rate is good. I had initially put the SSD into an external cradle (FW800) and the system was faster than on the internal drive. I only got a 1.5GBs SATA drive, perhaps yours could benefit from the 3GBs. I know the 6GBs would be too fast and costs a lot more, even the MacPros need special hookups to make use of the 6GBs.

Is there a way to export all of my music from my hard drive to an external drive, connected to my computer and have iTunes still work with the music library located on the external drive?

I do not have enough room on my hard drive for all of my music collection and want to export the music files to my external 300GB hard drive rather than purchase and configure a new, larger hard drive for my computer. Can I export all of my music library to the external drive and configure iTunes to always store music there, and operate seemlessly with the music library on the external drive?

I've been able to save/move things to my Western Digital Passpor beforet but this time it won't let me drag the project or event to the external drive.
Tons of space left on the drive. The prioject is not finished. Do I have to optimize it or something? Thanks for all replies.

external drives come out-of-the-box 'Windows'/fat32 formatted.
no prob for a Mac - except for iMovie.
use the Disk-Utility in your Apps/Utilities folder to format to 'Mac'.-

Data CD's won't Mount

I recently upgraded the RAM and operating system. Prior to upgrading, I had already noticed that CD's sometimes did not mount on the first try. After upgrading, it seems that data CD's mostly won't mount, audio CD's mostly mount, and DVD's mount.
Now, I don't use my CD drive all that much, so I don't know if this has something to do with the upgrade or whether it's just a coincidence. Here's what I've tried so far without success...
1) Repaired Permissions.
2) Repaired Disk from Install disc. Message indicated that no repairs were necessary.
3) Downloaded and re-installed Mac OS X 10.4.8 Combo Update (PPC), and repaired Permissions.
4) Tried a Safe Boot.
5) Tried booting FirmWare (AppleOption+OF), and entering the following commands:
set-defaults (hit return)
reset-all (hit return)
6) Verified RAM specifications.
7) Ran the Apple Hardware Test. All components passed.
Anyone have any ideas? Or do you think the drive needs replacing?
Thanks!

Are any commercial pressed CDs other than the Office
disc causing problems?
I just tried a number of commercially pressed CD's without a problem. These included 4 of the OS X Jaguar 10.2 CD's, Logitech, Lexmark, and Norton AntiVirus. I also tried an audio CD and had no problem. However, when I tried a data CD (Verbatim CD-R), it wouldn't load.
It's possible that the Office
disc is itself defective (MS should be willing to
replace it if it won't mount in any other Macs)...
That's great! I'll have to see if I can find someone with a Mac so that I can test the disc.
There are some CD-R/DVD-R stoarge tips at the NIST's
Care and Handling of CDs and
DVDs...
That's great! I'll check it out...
... although the single biggest step you can
take to ensure long CD-R life if to find high-quality
blank discs to use in the first place.
Which ones do you recommend?
Let us know about other commercial discs and if the
lens cleaner helps.
I didn't get a chance to buy the lens cleaner today, but I should be able to buy one tomorrow. I'll definitely let you know whether it helps.
Thanks for your help, JMVP!
Cheers!

External drive goes read only with error -50 after time

Running the special release of 10.8.2 for Mac Mini (2012) that was recently released. I have two external USB drives. The first contains my iTunes collection and the second is my time machine backup disk. The iTunes drive seems to go read only after it's been mounted awhile. I can read files off the drive, but I can't make any changes. I can't delete files nor edit them.
If I try to do anything with the disk including a repair permissions or disk on it, I get an error -50. The only way to get out of this state is to unmount the drive and remount it forcibly or reboot.
Anyone have ideas on what is going on or experienced a similar issue?

I did a little more research and there are quite a few people who've seen this error. I don't think it's the drive.
I suspect the controller in the enclosure, a jmicron 0x2336, is responsible for my problems. It looks like Linux and FreeBSD both had software updates to work around bugs in the controller. If OS X did not get updated, it would explain everything. The drive sleeps and then won't wake up fully and OS X marks it as in error and goes read only.
The enclosure is a Thermaltake Silver II USB + esata. It looks like a lot of people have had similar problems with them. I saw posts on macrumors, adobe's support forums, etc.

Urgent- External Drives stuck in CUSTOM.

Our IT dept. is new to MACs and set up my new I mac wrong the first time. I've been re-installing everything but both my externals are locked and set as custom. When I try to change the permissions they just switch back. I'm trying to use "Terminal" and put in some prompts I've found elsewhere but amy having major problems. And as you may have guessed, all my projects I'm trying to get done are on those externals.
Help me Apple Discussion Forum, you are my only hope......

Does this info help at all?
