Can I use a SCSI hard drive in a SCSI CD-ROM enclosure?

I have an external SCSI hard drive which has stopped working.
It has been going OK for some time, but has suddenly ceased completely, i.e. the light doesn't even come on when I plug it in.
I'm guessing from this that it may be the power supply that's at fault - which is good, because there is data on the drive I need to access.
My question is, can I simply transfer the drive to a SCSI CD-ROM enclosure and access it from there?
The reason I'm not just sucking-it-&-see is that I really really don't want to risk frying the drive, because some of the data is not backed up.
Any info much appreciated...

The vast majority of those jumpers have to do with SCSI addressing. Each device on the SCSI Bus needs a unique address. The Controller takes #7, the built-in CD takes #3, and the built-in drive (if present) is most often 0.
If you can reverse the jumper-block built into the case, you may be able to get the number dial to work. If not, you can ignore it and set the address semi-permanently with jumpers directly on the drive. There appears to be more than one set on your drive, just choose the most accessible set and use only those. It's the setting on the Drive that will determine the address, not the case.
jumper marked 8 counts for 8 if present
jumper marked 4 counts for 4 if present
jumper marked 2 counts for 2 if present
jumper marked 1 counts for 1 if present
add-em-up to get the SCSI address.
No jumpers give address zero. A final Address of either 1 or 2 or 4 can be made with only one jumper.

  • I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    In the Mac side of things, backups usually come in two flavors: clones or incrementals.
    A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
    Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
    As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
    Holler if you need specifics on how to do each. This was just an executive summary.

  • Can I use one external hard drive for 3 of my Macs?

    I have a 2007 white MacBook, a 2011 MacBook Pro, and a 2013 MacBook Air.
    I want to be able to transfer all of my precious family photos off of my MacBook and Macbook Pro onto an external hard drive and then wipe those computers clean, and then I want to be able to backup and wipe clean my Macbook Air so that I can update it to Mavericks.
    Can I use one external hard drive to do this for three of my Macs? Will it be compatible with all of them? And will I still be able to use the hard drive with my Air once it is updated to Mavericks?
    Which hard drive do you recommend?

    1. Yes. Note that anything you want to keep should be on at least two drives in case one of them fails.
    2. Yes.
    3. Yes.

  • How can I use my external hard drive for my iphoto instead of my mac book pro memory?

    i don't know if this question has been asked before: how can I use my external hard drive for my iphoto instead of my mac book pro memory? just like itunes all my song are save on my external hard drive. make sense?

    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

  • How can I use an external hard drive to both back up and free up storage on my macbook?

    I've used a hard drive to back up my 2012 Macbook Pro via Time Machine, but I'm not sure how to use it as external storage to move things like video and music off of my Mac to free up memory and then how to move the same things from the hard drive on to other devices like my iPad or iPhone.  For instance, I have a ton of movies and would like to store most of them on an external hard drive so that they aren't taking up all of my memory on my Mac, but want to be able to move them easily back onto my phone or iPad.  Also, can I use the same hard drive to both back up my computer and use it for external storage?  If so, how do I do that?

    Always use two drives for this: one for backup; the other for storage. Don't mix the two uses on one drive. There's a greater risk of data lost without that redundancy.
    If you plan to backup using Time Machine, then be sure the backup drive's capacity is at least twice that of the drive you are backing up.

  • Can you use a external hard drive to keep all your iTunes info on it

    Can you use a external hard drive to keep all your iTunes info on it

    Yes.
    The easiest way is to copy the whole iTunes folder out to the external drive, then press and hold down shift as you click the icon to start iTunes. Keep holding shift until asked to "Create or choose a library". Choose the library on the external drive.

    What problems specifically? If you have a problem you should start your own thread and explain the problem in detail.

    You want system, data, backup etc. Make good use of the four internal drive bays.
    You will have to use Disk Utility to ERASE or click on drive and use PARTITION to make it Mac writeable.

  • HT1766 Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

    Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

    You can store them on a separate hard drive, you don't need to keep them on your laptop's hard drive. On your computer's iTunes on the Advanced tab in Edit > Preferences there is a 'copy files to iTunes media file when adding to library' tickbox - if you untick that, you should be able to copy the films to a separate drive and add them back to your iTunes library (File > Add To Library) and it should then point to them on that separate drive and not copy them to your hard drive. When you are happy that it is what is happening and that they are safely on your external drive you can delete the films from your laptop's hard drive.
    If you plug the external drive into a different USB port next time (assuming that your laptop has more than one) then it might get a different drive letter, so you might need to always use it with the same port.

    Can I use a portable hard drive for ipad data storage?  I want an iPad mini, but don't want to get a large one (memorywise) along with cellular capability.  I remember that the old iPads coiuld not communicate via their iPhone connector to transfer data.  So can I do that iwth the newest iPad mini via the lightning connector somehow?  Thanks, Tom

    No. But you can with Seagate's wireless GoDrive.

    If you mean to hold iTunes content to stream then the answer is yes.  Your iTunes library  folder and the media usually live in the same location, but media can be in a different or several different locations.  The external drive wuld have to e connected and powered to stream media to AppleTV.

  • Can I use an external hard drive for my ipad mini?

    Can I use an external hard drive for my ipad mini?

    There are some wireless external hard drives that can be used with the iPad.
    The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
    Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.
    Another option:

  • Can I use a 40GB Hard Drive in my iMac G3 (Tray-Loader)?

    Can I use a 40GB Hard Drive in my iMac G3 (Tray-Loader)? Any help gladly appreciated!
    Thanks,
    Sean Butler

    As pointed out, for OS X you need a small <8GB first partition with the tray loading models. If you never plan to run OS X and will only run OS9, then you can format the entire drive as one parition if you like. But to be safe, if you are not sure, make parition one <8GB and partition two the balance of the drive space.
    As to your specific question, I have a 60GB drive in my 333MHz Grape Tray loader and it works fine, so yes you can put a 40 in there no problem.
