External 200 GB drive USB 2.0 - can't mount

Just wondering if anyone has had this kind of problem. I've purchased a 200 gb drive and have it hooked into my mac via a adaptec usb 2.0 card.
The drive refuses to show up.
Any suggestions?

Hello! First try using the motherboard ports to rule out a bad pci card. Then attache the drive and turn it on and open disk utility to see if it can repair it. If that doesn't work boot from the install cd and run disk utility from there to try and repair the drive. It has been formatted hasn't it? Tom

  • Can't see external exFAT hard drive in finder - but can see it under disk utility

    I have tried it all.
    Running Mac Air OS X Lion 10.7.3 - connected to wifi network via 3TB Time Capsule. Just bought an external HDD for moving around. Formatted as exFAT and loaded files from a friends Windows 7 PC. Tried to plug into TC but couldn't see it neither in Finder nor Time Machine. Then plugged it directly into Mac Air, still not visible under Finder. Tried the following without much success either:
    - Used the Verify & Repair functions in Disc Utility: No errors found
    - Tried to Mount in Disc Utility: Refused (advised to run First Aid) - Ran first aid twice and still can't mount
    - Used various apple scripts to unhide it: still not visible
    - Went to Finder - Go - Computer: Still not visible
    I'm now creating an image of the disc with the hope that I can mount the disc and acccess the files in it. Should this not work (and I have a strange feeling that it wont), what can I do (without the need to format the drive?)
    Thanks

    been there
    try this:
    use [_*Path Finder*_|http://www.cocoatech.com> (30 days trial period) to mount the drive and +get info+.
    find the entry for *alias bit*. if the box is checked, uncheck it
    that should do it.

  • I have a lot image files on external WD hard drive USB powered .i just purchased aperture and have initated an import into aperture of all photos on thatdrive.it has about 1.75gig of images. how long will that take--been 24 hours already???

    I have had several issues so far with my new aperture program, and this is the fifth time i have tired to collect all of my images (or nearly all) onto a single drive and be able to file them from my mac notebook...obviously one huge problem is that every timie the dog walks buy he knocks the cord out and i basiclaly have to start over again...
    but i have taped the cords in an managed to fly across country while keeping the whole import running---up near 24 hours constant now...
    anyway, i ahve a bunch of questions but my main one is, i think from reaeding up here that it could take a fulll week to finish this transfer (even though i beleieve i made it very clear that i only want to index the fiels from their current location and not to move any of them around at all....
    the only rush really is that i have my daughter's graduation pictuers and everyone wants to see htem but i don't really want to cancel this transfer after i have already spent 24 hours!!!
    sorry to write so much...
    thanks for any ideas....

    Max,
    It really can take very long to import and process so many images - I would not dare to make a prediction.
    Can you open the Activity Viewer?
    From Aperture's main menu bar: Window > Show Activity.
    This window will tell you the filename of the image that is currently being processed.
    if you are seeing, that the import is still far from being finished, you might to pause certain tasks directly from this panel, like the generation of previews or scanning for faces. I'd let the import run, if you see that it is making progress.
    Have you enabled very time-consuming options, like the generation of high resolution previes or scanning for faces and places? if yes, and the import is not making any progress at all, I'd disable thes options in the Aperture preferences for the initial import. You can add these later for the projects where you want to use these features.

  • [SOLVED] Booting Arch off USB HDD fails - can't mount real root device

    I've installed Arch on the internal HDD (sda) of my laptop, and I attempted to install a second copy of Arch on partition sdb3 of an external USB HDD.  sdb3 is a primary partition that I had prepared beforehand with gparted and outfitted with the reiserfs filesystem.  I skipped section 3.2 (manually prepare hard drives) of the Arch installer.  There was no problem with section 3.3 (manually configure filesystems and mountpoints); I put all of / in sdb3.  Installing packages and configuring the system also went without a hitch.
    I wanted to boot this new install of Arch via the boot menu of GRUB that was installed in the MBR of sda with my primary install of Arch.  On the new install, I first did go through section 7 (install bootloader), thinking I would want to install GRUB in the root sector of partition sdb3 (not in the MBR of sdb where the GRUB of MintKDE resides, a boot menu that I want to keep) but that failed, so I then picked "no bootloader to be installed".  With that I exited the new install, since it appeared to have gone to completion.
    I then copied the appropriate stanza in the /boot/grub/menu.lst of this new Arch install to the /boot/grub/menu.lst of my primary Arch install on the internal HDD of my laptop.
    This stanza reads as follows:
    # (3) Arch Linux on WDPP60 blue (sdb3)
    title Arch Linux on WDPP60 blue (sdb3)
    root (hd1,2)
    kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/191cc027-43ce-443b-8846-f265d60555ec ro
    initrd /boot/kernel26.img
    However, I'm not able to boot the new Arch install when I pick this entry from the GRUB menu list.  The new install starts booting, finds sda but not sdb and stops with the following errors, dropping me to a recovery shell:
    Root device /dev/disk/by-uuid... doesn't exist. Attempting to create it.
    ERROR: Unable to determine major/minor number of root device '/dev/disk/by-uuid...'
    mounting /dev/disk/by-uuid... on /new_root failed: No such file ...
    ERROR: Failed to mount the real root device.
    Running "mount -t reiserfs /dev/sdb3 /new_root" at the ramfs prompt also fails.
    I've tried a number of edits of the menu.lst stanza from the grub> command prompt, such as adding rootfstype=reiserfs, replacing root=/dev/disk/by-uuid..etc. with root=/dev/sdb3 (booting then fails with "/dev/sdb3  No such file"), using "initrd /boot/kernel26-fallback.img" etc., but booting always fails at the same stage with equivalent error messages.
    I have no trouble booting half a dozen other Linux/BSD distros that reside on two different external USB HDD's by the same method, i.e. choosing an entry from the GRUB boot menu of my primary Arch install, after I placed the appropriate stanza in its /boot/grub/menu.lst.
    How can I get this new Arch install to boot?

    Yes, this was in fact the solution.  I stumbled upon it in this thread:
    http://bbs.archlinux.org/viewtopic.php?id=65844
    When one wants to boot from a USB mass storage device, the initrd needs to include the modules for accessing USB devices, and in Arch this is accomplished by adding "usb" to the HOOKS array.  I simply reinstalled Arch to the USB HDD and in the system configuration step now edited /etc/mkinitcpio.conf by adding the "usb" item.  Adding "rootdelay=10" and/or "rootfstype=reiserfs" to the kernel line in the appropriate stanza in Arch's /boot/grub/menu.lst wasn't necessary in this case.  I left the stanza exactly as I posted it above.
    Thanks for your input.

  • External Lacie drive crashed, now I can't find a recent backup for LR3 catalog.

    I have LR3 on a Mac running OS 10.6.8.  My catalog, cache and images were stored on an external Lacie 1TB drive (partitioned so it can be used by a pc and mac).  My catalog backup files were saved on another external drive MXTR as well as copies of all my images.  The Lacie had started self ejecting while running LR3 and I thought it was maybe a problem with the cable, as it would work fine after rebooting.  Yesterday it crashed LR3 and never remounted.  I used Disk Utility to try and repair the disk and it instructed me to erase the disk and start over.  I was not worried, since my catalog was backed up to another drive.  10 hours to erase the drive (the drive never quit during this time).  Another 2 hours to copy my images from the MXTR to the Lacie (again the drive never self ejected during this time either).  So now I go to find my most recent backup catalog.  The most recent one I could find was dated 2/09/2012.  I am baffled.  What happened all those times I was backing up?  I upgraded to LR3 in 2011, and I don't remember ever telling it to backup to another folder or drive. 
    Any ideas as to what the problem may be?

    What happened all those times I was backing up?
    We can't possibly know what happend or where your backups are. But you can indeed search all of your available hard disks and see if there are any files named *.LRCAT with recent dates.
    By the way, I would be extremely wary of using that Lacie drive any more. If it was me, I'd replace it.

  • The Clicking hard drive, can't mount to restore

    So the click in the hard drive is common. Can't mount ipod to restore as hard drive starts clicks and stops. Is it hardware or software>? I also noticed a little circle with arrows appear in top left corner of the screen. Is it resolvable od do I need to send it in???

    It's a 40g, had it for 16 months, out of warranty.. Windows won't recognise it properly, the safely remove hardware icon appears in the bottom right of tool bar, but you can't stop it through that. Tried that article but disk management times out or crashes. I heard you can use windows to reformat, managed to get there once, but decided not to do it.
    It was clicking alot, I slapped it lightlyish a few times and the clicking is less frequent I guess. but windows still doesn't recognise. The first glitch occured a few weeks ago, so I did a restore, but then the next time I went to put some music in it, it just started clicking, drive stop starting, getting warm, and controls freezing, able to reset, but unable to upload to. Have removed other software on computer, possible conflicts, no solution, have installed newest itunes and updater. When I run the new updater, it launches an autoplay box, and nothing happens. Any info, or similar prob/solutions??? much appreciated

  • Can't mount two FAT32 volumes at once?

    OK-- I've done it once or twice, but now I can't---
    I've got two 500GB external WD drives formatted as FAT32 (the drives are sometimes attached to a PC at work) with different names and different data on each.
    I can't mount more than one at a time; if I dismount one drive, then the other can be mounted and vice-versa. I do this via Disk Utility. So if one drive is already mounted, then clicking the 'mount' button while focused on the 2nd drive makes that drive access light flicker briefly before it just gives up.
    Funny thing is, I have managed to do this once or twice on this G5 tower, and no problem at all on my MBP, both running OSX 10.4.9.
    When a given drive is properly mounted, it works fine, and both are in good repair according to Disk Utility.
    Is there a limit to the number of volumes OSX Tiger can mount if they're FAT32?
    Thanks!

    I recall a previous post ( among what are becoming many, many posts on these WD external drives not working regardless of bus) that they had different names but in the bowels of the drives/bridges they were showing up as the same drive and OSX can't deal with that. If they are multi-input trying one on USB and one on firewire would be interesting.

  • ICYBOX IB-AC6031-U3 external drive enclosure USB 3.00 can't see my data!

    ICYBOX IB-AC6031-U3 external drive enclosure USB 3.00 can't see my data!
    Hello to the community,
    So indeed a pretty self-explanatory title. However you might not think so later.
    I just received the ICYBOX IB-AC6031-U3 today from ebay. (But it's a product of RaidSonic) over in Germany see link:
    www.raidsonic.de/en/products/external-cases.php?we_objectID=8887
    The problem:
    I have a large 1.5 TB seagate drive (15mm in height) which was originally in a iOmega external case (which was poor, thats another story).
    The ICYBOX IB-AC6031-U3 is an extremely portable hot swappable enclosure/caddy. (Please do see the images from the above link). However when I plug my seagate HDD into the ICY adapter, it, my Mac cannot see the data I have on it whilst using this adapter! But If I use the old one my data can be seen, see images!.
    You see in disk utility, before the above. A small dialog box giving me three options "initialize, and two others" appears, initialize takes me into disk utility. Shows as "ASMT 2105 Media" (not one of the partitions on the drive).
    Below see connected to new ICYBOX enclosure/case: (don't ask me why it inserted upside down?)
    And below using the old USB3.0 sata cable and adapter from the previous enclosure. Note that it works, my data can be seen, read and wrote. On the monitor you can see my "Data core" partition mounted!
    As you can see the above is the drive plugged in using the old adapter and cable (SATA chip + USB 3.0) from iOmega. This works no problems you can see my partitions mounted and yes they do work.
    This is disappointing as far as the  ICYBOX IB-AC6031-U3 is concerned for me. It should just work out of the box. But no it can't mount or even in anyway see my partitions that are definitely there. I want to use the ICYBOX IB-AC6031-U3 for this drive and should be able to but I cannot reformat and don't want to as this is the biggest drive a have at the moment.
    There has to be a way around this, I have contacted RaidSonic who make the adapter and await a response. I have also done some  web searching but nothing promising has turned up.
    Your input will be greatly appreciated,
    Many thanks,

  • My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

    My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

    Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
    Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
    Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
    Quit and you should be able to install OS X now with your Apple ID and password.

  • Can't Mount External SCSI to USB Drive

    Hi guys- I currently have a problem involving an external scsi to usb drive that I can't mount. I tried the usual commands, fdisk -l, mount, lsblk, to discover the device but it's not showing up in /dev.
    I ran lsusb -v and one section shows "mass storage" and since I don't have any other mass storage devices attached other than my /dev/sda, my guess is that this is the device. Below is the output of lsusb -v, how can I use this info to get this device mounted?

    I'm using the latest kernel. The device is a macally Hi-Speed USB 2.0 external drive enclosure. Yesterday my BIOS was detecting it, and later that night I actually mounted the device with mount /dev/sdb1 /mnt/drive_2, I fired up the computer today and it's not there anymore, not in BIOS, not in the OS. This thing is acting very buggy and It's starting to scream hardware issues. There is a blue light on the enclusure that tells you when everything is okay, but now the light is red. Plus I can't hear the drive spinning.
    arobson- I tried your suggestion and ran udevil monitor and a message popped up "Monitoring activity from the disks daemon. Press Ctrl+C to cancel." Then I plugged in the drive but I'm not sure what's supposed ot happen. I didn't get any messages after that.

  • Two external FW drives - Can't mount both at same time?

    Hi, I just got two new 200 GB ATA drives and I've installed them in two separate cases. I have managed to get both drives formatted and mounted, but only one at a time. If I have one drive switched on and mounted, as soon as I switch the other one on, the system hangs and I get the beach ball. If I then switch off the drive I just put on, things return to normal. If I unmount the first drive and switch it off and then turn on the second drive it mounts normally.
    I have another FW drive with a different type of controller in its case (Oxford Semiconductor Ltd). I can mount that no problem and then mount either of the two new drives. The only thing I can't get to work is the the two new drives in their cases made by the same manufacturer. System Profiler says that the external cases contain Prolific PL3507 Combo devices.
    I have tried every way of connecting the drives - i.e. two cables one from each drive to each FW port on my computer and also daisy chaining the drives, but I still can't get the two new drives to mount together. If I use my old FW drive and one of the new ones, I have no problem getting them both to mount with two cables or daisy chained.
    So I'm stuck now - any advice I can get here will be greatly appreciated. Thanks in advance.
    Powermac G4 MDD 1GHz DP   Mac OS X (10.3.9)   2 GB RAM

    Thanks Malcolm - Do you think it might be worth trying to flash the firmware on these cases - there seem to be updaters available on Prolific's website. Obviously I'd have to do it on a PC. I've emailed Prolific asking them about my problem. No reply as yet, and I'm not holding my breath! Do you know if there are any other posts on these boards relating to Prolific? Stupid question really - I'll just do a search...
    Thanks again for your post. Cheers from Bonnie Scotland.

  • How to work with database files on an external hard drive (USB 2.0 or 3.0)

    I have Oracle 11gR2 installed on my laptop. I would like to create a database instance on my laptop, but to put the datafiles on an external hard drive (USB 2.0 or 3.0). The external drive will always be attached to the laptop, whenever the database is used. This is going to be a development machine, just to develop a prototype. Laptop is limited to 150 GB on local disk and I want to have a 1 TB database on it. Can this be done with Oracle 11g for Windows XP SP2 ?
    I presume that a network attached storage NAS device would be better solution, but I cannot attach it on my LAN.
    Thank you,
    Milan

    Sure. You can put the data files wherever you'd like assuming that the external drive is going to be mapped to the same drive letter (I'm guessing your laptop is running Windows).

  • Is it possible that iMac corrupts connected external hdd-s drive via USB?

    Is it possible that iMac corrupts connected external hdd-s drive via USB? (two wd cav. green 2tb from different purchase went down in one day, both from the backside usb ports)
    First one of my video storage hdd, full of files suddenly got extremely slow, and a few minutes later, it unmounted itself, but with the unmount error, but nobody even touched the cables, electricity etc. When I tried to mount it again, it did not respond, just give a periodical load light and ticking. First I thought it must be hardware failure, but since I bought a brand new drive today and it made the same problem as soon as I tried to format it. I got suspicious. The consol, said about these - i googled all but now solution so far. (WesternFresh is my drive)
    Oct 23 17:10:58 xxxx fseventsd[47]: disk logger: failed to open output file /Volumes/WesternFresh/.fseventsd/636573acca1d6550 (No such file or directory). mount point /Volumes/WesternFresh/.fseventsd
    Oct 24 10:55:42 xxxx com.apple.kextd[10]: Can't create kext cache under / - owner not root.
    Oct 24 17:23:05 tmdc diskarbitrationd[16]: unable to probe /dev/disk1 (status code 0xFFFFFFFA).
    and there was an I/O faliure not but it was on another mac - where i hoped itt will come back to live.
    I think - if it is possible - that the OS maybe misunderstand something about these drives, and try to change - maybe permissions - all the time if a usb external connects...? (I am not really into it as you see )
    Also about Disk Utility - it does not see any partition on the old hdd, but i shows the name of the product. If I connect the new hdd via the keyboard usb, the disk utility is able to see and format it, but the hdd will be still slow and tikking after it.
    Also I tried Disk Warrior (freezd out) and Techtool Pro 6 thanks to some ol'frineds - which also not saw the old hdd, but did nothing useful with the new one.
    About cav green: I have 3 of them and no error so far, and got 4 1tb cav green in 2 mybook studio II also without any problem.
    Iam a bit scared, and try not to plug in any usb hdd-s now, but I have to continue work, so I need solutions.
    I hope if it is not hardware failure, maybe some tricky terminal code will bring back the viability of my old hdd - and I won't have to spend a lot of money to recover data.
    strange.
    if anybody has a clue?
    update 1:
    i found this post also:
    https://discussions.apple.com/message/15905481#15905481
    I also made the mentioned steps - but it is a bit different sice it reproduce itself and I cant use DU.

    It turned out that WD is the big bad guy in this game.
    According the data rescue company where I asked for an inspection, both of the drives had their reader head loose. And in the one, which was my already-in-use disk its even damaged the platters... xxxxx
    So its time to pay bunch of money to recover, and take a walk to wd service to bang on the desk.
    Also note - it may be somehow related to intellispeed technology - since macs not really friendly with wd-s built-in solutions.
    On the other hand, with WD GP 1Tb there is no problems at all for ages.

    From the menu bar, select
     ▹ System Preferences ▹ Energy Saver ▹ Power Adapter  
    and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
    If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
    Check that the data cable is securely inserted at both ends.
    Try a different cable.
    If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
    If you're connecting it directly, try a different port.
    Disconnect all other devices on the bus, or as many as possible.
    Test the drive with another Mac. Test another drive with this Mac.
    If the drive is bus-powered, but has an AC adapter, connect the adapter.
    Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
    Start up in Safe Mode and test.
    Reset the NVRAM.
    Reset the System Management Controller.
    If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.
