Disable acces to external storage usb or firewire

Hi.
I need to disable any external device like hdd usb or hdd firewire and usb key as well. Is there a way to do it in osx lion server ? I've heard that deleting some extension could do that job but which one ?
Thank's for your help.

This can be done with MCX, allowing enforcement to select accounts if needed. What is your directory infrastructure? Are you backed by AD or OD? Or are these local account?

External HDD-USB or Firewire

Hi, I'm quickly filling up the hdd on my iMac with video editing so I've decided to buy an external HDD. I was under the impression that Firewire was the best way to go, but after reviewing the specs on the Seagate FreeAgent Pro 500, is seems that the transfer rate on USB 2.0 480mbs) is faster than firewire 400 (400mbs). A firewire drive is more expensive that just a USB drive, and I don't mind spending the additional money if it's required, but now I'm confused. Should I buy a firewire drive, or can I get a faster transfer rate, and save money by going with a USB only drive? I have an early Intel iMac, so I don't have firewire 800 or eSATA ports on it.
Thanks for your interest...

I did some practical testing, transferring a 1GB file from the iMac to a Lacie d2 triple.
USB 2.0 - 147 Mbps
FW 400 - 294 Mbps
FW 800 - 426 M bps
Speeds transferring the same 1GB file from the Lacie to the iMac averaged about 30% faster.

External HD - USB or Firewire ? ? ? ?

Which is the best way to go when using an external hard drive?
USB 2.0 or Firewire?
I heard Firewire is better but why? or is it a myth?

Just as a caution, my experience with external hard drives has not been so great. The drives constantly disconnect/reconnect which causes problems with large file transfers, and if there's anything out of the ordinary then OS X freaks out and either slows to a halt or crashes completely. I've used many different drives, and many different interfaces.
However, I've found that using Firewire seems to be a lot more stable than USB. And most Firewire hard drives have two Firewire ports so you can continue daisy-chaining Firewire devices without a hub, which is nice.
It's a trade-off, at least in my case, since USB is more unstable but more standard than Firewire. USB was never really designed for use with external hard drives, and has a higher overhead for file transfers than Firewire, which probably explains its potential instability. USB was designed to replace serial ports, while Firewire was designed to replace SCSI...Choose carefully.

How to transfer photos from a MAC to a USB external storage drive?

How to transfer photos from a MAC to a USB external storage drive?

Just the Photos? Or the Library?
If it's the Library:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Library on external USB or Firewire?

In case anyone has any doubts about Firewire being faster than USB, I just moved my library from an external 1Tb USB drive to a Firewire 400 drive. The difference in speed is amazing, I can move the adjustment sliders in realtime with no problems, previously it was click on a slider, wait for its effect, then click etc.
So if you are using a USB drive for a managed library and are having speed issues, I suggest you invest in a Firewire drive, you won't regret it
David

In my real world testing moving GB's of data around, FW800 and USB (if I am not doing other things on the computer) pretty much operate in a similar fashion. This has always been a bit surprising to me. And for small amounts of stuff USB 2.0 is fine.
BUT, Western Digital is now offering USB 3.0 drives which per spec are 10 times faster transfer rates!! Now that really has me drooling. Steven

Is the enclosure locked? External drives won't mount if the enclosure is locked, typically.

External Hard Drive...USB or Firewire 400

I just purchased a new iMac (I'm coming from the P.C. world) and would like to purchase an external hard drive for backup purposes. I was wondering whether to purchase a USB, Firewire, or a drive compatible with both. Which runs faster on Macs? I was looking between the following drives:
Western Digital MyBook 250GB (Combo): http://www.compusa.com/products/productinfo.asp?productcode=338216&pfp=compare&
Western Digital MyBook 250GB (USB): http://www.circuitcity.com/ssm/Customer-reviews-for-Western-Digital-External-Har d-Drive-WDG1U2500N/sem/rpsm/oid/145402/rpem/ccd/productDetailReview.do#tabs
LaCie 250GB (USB or Firewire versions): http://www.compusa.com/products/productinfo.asp?productcode=310799&pfp=compare&
I also read about the different chipsets, but since these are all compatible with Mac OS X, they should have the proper chipset. Any help would be appreciated.

I recommend getting an external HDD with both firewire 400 and usb2. First off firewire is faster in real work operation than usb2. Is also good to have both if you decide to take some files and hook the drive up to a PC. Alot of PCs still don't have firewire.
I like this drive from OWC. It uses the latest Seagate drive and very good chipset.

10 3.9 - external drive crashes PB when connected by USB or FireWire

Subject says most of it... "10 3.9 - external drive crashes PB when connected by USB or FireWire"
Details: I have one external drive which, when connected to my PowerBook via either FireWire or USB, causes the computer to lock up with the message: "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." The same thing happens whether the drive is there on bootup or if it is connected later.
The drive worked fine until yesterday, when I stupidly installed Windows Media Player even though the internal drive was almost full. It took a while, but I discovered that disconnecting this particular external drive made everything work again, though slowly.
Then I freed up 15GB on the internal drive, and everything works normally _unless that drive is attached. Another drive connected the same way works fine.
I have searched around on this message but have yet to find the way out. I did figure out what the first question will probably be, so here's the answer:
The "kernel panic message" each time seems to be the date and time and then "localhost /usr/libexec/panicdump: Error (-1) setting variable - 'aapl,panic-info'"
Where should I start?
Thanks.
15" Powerbook Mac OS X (10.3.9) External drives connected via USB or FireWire

Still hoping for some sort of advice here... Have tried many approaches but can only confirm that simply connecting that particular drive (or enclosure?) always gets an immediate shutdown.
Thanks for anything,
Steve

Kernel panic when using FAT formatted external storage

I have a PowerBook G4 17" with 1GB RAM and since updating to 10.4.8 from 10.4.7 I have received on three occasions a kernel panic, i.e. a message that says "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button."
Looking at the conditions under which this event occured, on all three occasions, this looks to be disk I/O related using external drives however the cause could be something else like Spotlight indexing for example - I am hoping this is not hardware.
On the occasions where the problem has occured the attached storage devices have been:
1. A FAT formatted, bus powered Firewire attached 2.5" IDE drive
2. A FAT formatted PC Card drive
I had this happen to me last night with the PC card drive when I found I couldn’t delete any data from the drive but could write and overwrite data. My internal IDE drive seems to be fine however I decided to eject the drive and reinsert it but on reinsertion the system could not see or mount it. I then tried a FAT formatted CF card with PC Card reader/adapter – same thing, it wouldn’t mount. I then decided it was time to reboot and that is when the message popped up as the transparent grey bitmap (http://docs.info.apple.com/article.html?artnum=106227). After rebooting I got a kernel error stack trace telling me something bad happened hence the reboot. This thread seems to be very similar to my problem except with a new Intel version of the 17":
http://forums.macnn.com/90/mac-os-x/312947/what-does-mean-when/
Any ideas? In all cases this has occured when using an external FAT formatted drive and actively writing data to it - it doesn't seem to matter how it is attached or specifically which drive it is. I have not had this problem previously when using external storage media and I am not using any backup software when this occurs - I am simply saving files from various applications be it PhotoShop or a Safari download. One last note, I am using Intego VirusBarrier X4.
Right now my plan will be to run the disk utility, disable anti-virus and possibly disable indexing on external drives and try to reproduce the issue - the only problem with this is with the exception of the 10.4.8 update, what changed?
PowerBook G4 17" 1.33Ghz Mac OS X (10.4.8) 1GB RAM

Funnily enough I can backup to my USB attached bus powered 2.5" drive formatted as Mac OS Extended, this is why I am wondering if there is a relationship between externally attached FAT formatted storage and kernel panics.
My system disk checks out with no errors BTW - I also rarely travel with my PowerBook so it is relatively well looked after and should have a lower exposure to issues relating to faulty hardware.

Daisy Chain USB To FireWire?

Hi all.
I'm not really sure where to post this, so any suggestions about a better place would be great. Anyway, here's my question.
I do a lot of work with photos, and they take up a lot of hard drive space, so what I'm planning to do is this: I'll buy a big external hard drive with lots of connections (1 USB, 2 FireWire 800, 1 FireWire 400). I'll also buy a smaller external hard drive with much less in the way of connections (1 USB only). The big drive will act as my main storage drive, with all the files for each image included on it. The smaller drive will act as the bakcup drive, with the top 20% or so of my best photos in only a compressed format on it. I want the smaller (backup) drive to be as cheap as possible, as I don't have much of a budget at all. Here are the two drive selections I've made: big drive:
LaCie Big Disk Extreme+ Triple
Small drive:
WD Elements
Desktop
So, here's the question: I know that you can daisy chain FireWire drives that have more than one port together, like this:
A cable from FireWire port on Drive A to FireWire port on Drive B, then a cable from another FireWire port on Drive B to the FireWire port on computer. I know this works (right?).
But I don't want to have to spend more money on Drive A (the backup drive) so that it has a FireWire port. Since Drive B (the main drive) has a USB port, I thought I would run a USB cable from Drive A to Drive B like this:
*Setup 1*:A cable from the USB port on Drive A to the USB port on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on the computer.
Will setup 2 work? Will the data from Drive A make the crossover from USB to FireWire? If not, I suppose I could also use this setup:
*Setup 2:* A cable from the USB port on Drive A to one of the FireWire 800 ports on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on my computer. Will this work better? Do USB to FireWire 800 adapters really work?
So, basically, all I really need to know is whether or not Setup 1 will work, and if it doesn't, whether or not Setup 2 will. Also, if anyone has any info/reviews/stories about the two drives I've selected, I'd love to hear that as well.
Thanks so much in advance for any help I get. Sorry about the long post; I hope it made sense.
Thanks again.
Nate

What about Setup 2, though? Does someone sell a USB to FireWire Converter?
Nobody has heard of a USB to FireWire converter that works.
The first example you gave would require a USB B to USB B cable or perhaps a "gender bender". Both of the drives you're looking at seem to still use the original full-sized USB B port, while many have gone to the mini-B. It wouldn't work anyways since both are USB slave devices. USB was never designed to daisy-chain.
Why can't you just connect the USB-only device to the USB port. If you're strapped for ports, then maybe a USB hub. You wouldn't even need a powered hub if you have a few low-powered devices and this external drive which doesn't use bus power.

External drive - USB or Fire wire or AC

Hello I dont know where to put this question so: Which would be the best for a 500GB external drive, USB & fire wire or AC? I want a portable external drive (2.5) but am not sure whether AC is best route or if USB/Fire wire?
Thank you

Which would be the best for a 500GB external drive, USB & fire wire
Use FireWire, not USB.
I ALWAYS build my own drive (takes 5 mins). More storage and less money.
 I like the TD-M120 enclosure, it's the best I know of.
Has a cooling fan, shock absorbers, and all the ports you will ever need.

MBA and iMac as display and external storage

Hi there,
I currently have only Macbook Air 2012 and I know that buying an iMac I can use it as an external monitor (price is almost the same as Thunderbolt Display). I'm thinking if connecting iMac to my Macbook I could access iMac's HDD (to use it as an external storage for films, photos since my Macbook is only 128GB ssd). Also if I can connect USB devices into iMac's ports and access them on my Macbook like it's possible with the Thunderbolt Display.
Thank you!

OK, i found that apart from Target Display Mode there is also Target Disk Mode. But can I combine them at the same time?
(I want to have iMac as external hdd and display, but browsing OS and apps from my Macbook).
Also, do I have enough ports in my Macbook Air (2012)? Thunderbolt goes for screen sharing, but I heard that for Target Disk Mode I need firewire cable? Do I have this port at all in my MBA?

Stackable external storage?

I need to add some external storage to my mini and I'm looking at an Iomega MiniMax 500 GB USB 2.0/FireWire 400 Desktop External Hard Drive 33746. Has anybody had any experience with this one or other brands/models? The space on my desk is tight so it has to be one that my mini can piggy back on. I just want a quality/reliable drive. Any input is much appreciated... : )

Thanks so much for the input tm311. These look like a better drive than the iomegas. I see they are also available already equipped with hard drives. Can you tell me if these are quality drives? What would be the advantage of installing your own drive?

Looking For Affordable External Storage Array

Hi All,
I'm playing around with the idea of adding a ton of storage to our G4 Powermac running 10.4.x Tiger Server and the xServe RAID seems like a really attractive option but the current price seems a little high for our smaller operation.
I'm wondering if there are any sys admins out there that have successfully got an external RAID (from another vendor) running RAID 5 working with their OS X Server systems on the cheap? Let's say $2k - $4500 for 3TB+? Am I crazy?

How much disk storage do you need for your applications? 3TB? That's three or four disk spindles. More, if you want RAID.
How much I/O bandwidth do you need?
Connectivity?
The FC SAN storage provided by Xserve RAID is more expensive than a rack of SCSI disks and an UltraSCSI PCI controller, which is more expensive than a pile of USB disks, etc. Somewhere in there you'll find various network-attached storage (NAS) options. FC SAN is more flexible and expandable, and rather speedy.
If you're just looking to add a few terabytes to a single box, a FireWire or USB solution might work. There are some discussions here from recent times -- search for "Drobo" and you'll find one of my postings in the thread -- or you might look to stuff 2.4 TB into an Xserve, for instance, and retire your G4 as a server. Or configure an Xserve and a rack of SCSI disks, and off you go.
Low-end external storage boxes are running about US$1000 per terabyte, and less.
BTW: RAID-5 is comparatively hazardous due to its window of vulnerability during recovery (and a number of sites have encountered failures due to recovery-level I/O), and comparatively slow due to its massive I/O hit during recovery. Start here for some details on disk failures and pointers to technical papers from CMU and Google:
http://64.223.189.234/node/353
http://64.223.189.234/node/410
But allow us to start the discussion with an idea of how much storage you need for your applications, how fast does your I/O need to go, do you need multiple hosts? (And the old mantra -- cheap, fast or good: pick two -- holds with storage, too.)
