Recommenadation for small external drive

I travel a fair bit, and am looking for a small (100-160 GB) drive that I can use for editing movies when on the road. I do have a larger external 250 GB firewire drive at home, but it's a bit cumbersome for travel purposes.
Is there a small external firewire drive that I can use when I'm travelling that someone could recommend? One that doesn't need any external power? Or does it basically need external power to spin fast enough to do editing in iMovie and Final Cut Pro?
Any recommendations?

"..There is no OS on such a drive .... so why journal it?.."
There's no Operating System on a scratch disc, but there are files. If the computer crashes - you trip over the cord, and it's not a 'MagSafe' - the directory of what's on the disc may get corrupted ..so there are files, e.g; video files, on there, but the computer can't find them when the power's plugged back in ..if the directory's corrupt because it was being re-written when the power went off!
A 'journaled' disc should contain info about what was on the disc before the crash (held in a non-corrupted directory) and where to find it ..so that the directory can be automatically rebuilt from the 'on-board directory backup', although the very latest additional file(s) might seem to have vanished. The 'journal' shouldn't get corrupted if the power vanishes while a directory's being written, because the 'journal' is always the previous, already-written, SAFE directory.
So 'journaling' keeps track of what was on the disc just before disaster struck..
",,Why would anyone see a need to rebuild the OS in the event of a power failure of a HD that is used exclusively as a scratch disc?.." ..You wouldn't rebuild the (non-existent) Operating System; you'd need to rebuild the directory - the list - of what's stored where on the disc; which segments contain "Clip 01.dv" and which disc segments contain "Extracted audio clip 29", etc.

Apple physically replaced the HD on my Imac. I backed up everything on a Seagate Go Flex Desk for Mac external drive for Mac. I went through the motions to restore my Iphoto Library back to my computer. Can't find them!!!!!

Apple replaced my hard drive on my Imac. I'm lucky I backed up everything on a Seagate Go Flex Desk for Mac external drive via Time Machine . I followed directions in order to restore my iphoto library , but I can't seem to find it on my computer. Are the files locked?

No reason to assume they are locked. The library will be restored to the location it was backed up from, unless you specified somewhere else. Have you looked in your Pictures Folder?

Is it OK to use USB 2.0 connection for Glyph external drive and Mac Pro as project drive?

Is it OK to use a USB 2.0 connection for Glyph external drive and Mac Pro as project drive? I was told by Sweetwater tech support to use Firewire, but both the FW400 and FW800 connections crash my audio interface software mixer (Presonus' "Universal Control" software).
Both Firewire connections also create a 10 second hang for each Command-Save that I do.
USB 2.0 for the external drive seems to be working so far, but is there some reason I should be wary of using this as my go-to project drive? In other words, I am imagining that there was probably some definite reason that the tech support guy mentioned not to use it. But maybe not. It's a brand new Glyph. In any event, it's nice to have the 10 second hang eliminated, and I was just looking for some advice, since digging into the Presonus software issue could take some time.

If you have a mac pro, why not stick the external HDD inside via one of your many SATA cables & have it run 9 times faster than your USB?
Or stick a HDD CADDY in your mac pro, so you can slot in a full sized 3TB HDD for recording, and when you are done, pull it out & slip it in an external enclosure if you need to take it places?

My imac won't recognize my passport for mac external drive

I just bought a WD my passport for mac external drive to back up my imac with Snow leopard OS. the passport icon doesn't show on the desktop and when I look using disk utility the external drive isn't recognized. The external drive has nothing wrong with it as I plugged it into a newer imac running 10.9.5 and it works fine on that machine. I went through the troubleshooting steps from WD and the only one left is trouble with the OS. I have updated the software and downloaded the drivers from WD and still no change. Any suggestions? thanks!

Need Small External Drive for 700MHz G3 iBook

My wife has an 700MHz G3 iBook 14" with 30GB HD.
Long ago she outgrew the size of the hard drive.
After twice replacing the logic board I'm reluctant
to put any more money in the computer itself but
would like to expand her storage. She'd love to use
one of the smaller pocket drives but after trying out
the Fantom Titanium Mini I realize the iBook's older
USB ports are a stumbling block (it wouldn't provide
enough power to operate the external drive). Are
there any other smaller USB or Firewire drives that
would work with her machine? Thanks!

I don't know a lot about Wes's family, though, except his parents lived in Gothenburg, Nebraska, and that's where he and his siblings were raised. He is the eldest, and is in his 70's.

Time machine is making two backup folders for my external drive

I have two external drives connected to my iMac, running 10.6.8. One is the Time Machine drive; the other is PhotosMovies. I've been having trouble for the last several months where about once a week my Time Machine backups won't finish, no matter how long I wait. I may have figured out that it gets hung when I have left a Sparsebundle open and the computer has gone asleep.
But to my question: while trying to troublesheet this problem I also noticed that for the past several months of my backups, within each backup set there are three folders: iMacHD, PhotosMovies, and PhotosMovies 1. I believe at some point that disk was named PhotosMovies 1 because I replaced an older drive with a newer one and I renamed it after I copied everything over and verified the contents.
If I exclude PhotosMovies from the backup in Time Machine preferences, that folder disappears from the backup set but the PhotosMovies 1 is still there. It is the correct size.
How do I get TM to understand that PhotosMovies 1 is no longer on the system?

Does the drive have its own external power supply brick or is it bus-powered? Firewire or USB?
Try resetting the buses per the five steps listed in this document: What to do if your computer won't recognize a FireWire or USB device

Looking for a correct solution for fast external drives

It is unfortunately after having bought already 8 LaCie external drives of 500 Gb to 1 Tb a few years ago (Firewire 400/800) for my MacPro that I heard from this forum that I should never use these drives for video backup because being unreliable. The poeple who said that were right. Out of the 8 drives, 6 are now dead (disc failures) and lost some precious files.
So now I am looking for a more reliable solution : I read somewhere that I could have for external storage a PCIe SATA controller w/ RAID performance; a solid SATA case for 4-8 drives perhaps. But when looking at SATA controller on the web, I am not certain whether all these cards work on a MacPro (the first Intel 2006 model with Mac OS Tiger 10) or just with Windows. Can someone advise me on what would be the right SATA card to buy for that computer, where to find them and what case I could link it to to install several hard drives ?
(By the way, my 4 hard drive racks inside the MacPro are all used already.

I’m on my third G-Tech external drive and I love their quality. I simply grew out of one and gave it to my son. The new mini works great too although my MacPro doesn’t like it when I partition the drive. It tends to stutter a bit and can lock things up on the MacPro. Still, I plan on buying the G-Safe as soon as I can. They certainly offer RAID Enterprise units although I haven’t used them. G-Tech uses Hitachi drives as the company is owned or associated with Hitachi. Either way, they’re hard to beat.

HT201250 Is there a size limit for an external drive to be used with time machine?

I have an iMac with a 2TB drive. I have a 2TB WD drive used for Time Machine that is full. I would like to go to the bigest WD (type) external drive that will work with Time Machine. Is there a TB limit for TM in OS X Lion?

Welcome . I have also used a 2TB WD My Book ext HDD for Time Machine backups for the past year and have had no problems. They seem to get a very bad wrap. Perhaps we are a few of the lucky ones. The two brands recommended by macjack are very, very good brands.

Suggestions for formatting external drive with bad block?

I have a OWC Mercury 300 GB external drive. I wanted to erase it and use it as a backup for one of my laptops. The drive had been working fine as a Time Machine back up for an old (intel) iMac. I told Disk Utility to erase and reformat. It erased, but refused to reformat saying there was a bad block on the drive. Now Disk Utility recognizes the external drive but won't do anything with it. No Verify. No Repair. All grayed out. Any suggestions?

I wasn't a hard error, that's why. Repartitioning and reformatting will often fix soft errors in the directory structure. Had there been a real, new, bad block on the drive it would not be repairable. A soft bad block error can be fixed by reformatting. The hard block error may be fixable by using Zero Data one pass that may spare out the bad block. But if none of that works then you need to replace the drive.
You were fortunate that the error probably was spurious and resolved by repartitioning (may have been in the disk's RDB.)

Best strategy for using external drive to speed up painfully slow mac mini

I have Intel core duo, and LaCie external drive. Many programmes are almost unusably slow. Like Adobe Photoshop, Garageband, Logic Express, SecondLife etc... (would have been nice if apple had told me the 'improved spec' would mean so many programmes would no longer work!)
I am looking for the best way to utilise the external drive. I have now set up to boot from the LaCie, but it is no better. Id like to know whats best to do with the two drives. Would one be best kept as clear as possible? And should that be the bootup drive? Originally, the idea was to increase storage and backup. Now it is anything at all, that will make this computer faster. My old G4 PowerMac is actually faster and more reliable!
powerMac G4 Mac OS X (10.3.9)
powerMac G4 Mac OS X (10.3.9)
powerMac G4 Mac OS X (10.4.9)

There is no way to improve on the graphics card in your mini - it's built into the logic board and can't be bypassed. However, while that may be a disappointment, it has to be said that by and large the graphics system in the mini is actually very capable, and is probably not the cause of the problem.
What IS the primary issue I suspect is the 512Mb RAM, which on a Core Solo running applications such as Photoshop is so woefully inadequate that it would be a surprise if your old G4 wasn't somewhat faster!
The problem is that Photoshop (the version you have) is not Intel-native, so while it runs, it requires Rosetta. Thus you have a RAM-hungry operating system, a RAM hungry application and a RAM-hungry translation package, all running at the same time. To add to that, since the software is not Intel-native, it has to be translated on-the-fly so considerable CPU time is needed to devote to that process in addition to all the other things the system needs to do in order to run.
Thus your external drive would not help much when used as a boot drive because even though it is likely to be somewhat faster than the internal, the limited RAM of the system will be forcing so many 'paging' actions (writing and reading memory blocks to the hard drive) that any speed gains will be rather heavily masked.
Most of the performance problems you experience can be resolved by upgrading RAM to 2Gb, simply because that will allow MacOS, Rosetta and your software a lot more room to breathe and significantly reduce the paging activity of the system such that then booting from the external will show notable improvements in responsiveness.
Alternatively, you may find that there are Intel-native alternatives to your software which may be available at reasonable cost and provide the features you need. Good examples are such things as GraphicConverter, which is shareware and does much of what Photoshop can do, and NeoOffice, which is open source and free, which is a good alternative to MS Office. These would run without Rosetta and provide you with much improved performance as a consequence.

Strategy for 2nd External Drive & Backup?

Hello All,
My IT guy at work just passed through my office and said, "you should be ghosting that thing." He was referring to my 1 Terrabyte hard drive that holds all of the footage I have recordered and transferred from my camera. I have now filled half of my LaCie 1TB external drive, and would like to prepare for the future.
So, advice is welcome, but I'll float a balloon of an idea. I propose purchasing a 2TB LaCie, so I have room to grow, as well as back up existing footage.
What do you think?
Thanks.
DG

Get a drive housing that supports removable drives. Granite Digital and Caldigit make such devices.
Back up to a drive then take it out an put it in a static resistant bag in a secure place. You can grow in an unlimited manner for much less than purchasing full housed drives.

Can a computer make problems for an external drive

I have an iMac G5 about 5 years old. All my external drives (5) are starting to give me problems. Could there be something wrong in my Mac that is hurting those drives?
Thanks so much,
D

At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.

Hard Drive upgrade for secondary external drive

Hi experts,
I have the 300Gb internal drive (#1).
I also have a 650Gb external drive (#2) I use for Time Machine as well as storing other files (overflow).
I'm looking to get a network attached drive (#3) so I can
- access it through my home network
- expand my storage
- use it to backup my internal drive, and my extra file contents in my external drive #2.
Can TM backup my internal drive and external drive(s) (or can I only pick ONE)?
Will I be better buying two MORE external drives? I'm really confused with backing up external drives, and I don't really think I need a RAID solution, just HD crash recovery.
Ideas?

What I really want to do is have a NAS to share stuff so that my TV has access to it, have a bit more space and have backup protection on all my data. This means I would need to reconfigure as such:
existing internal drive (1) essential os, applications (A)
existing external drive (2) work, tv shows, movies (B) (remove TM backups to free space)
new external drive (3) Time Machine backup (to backup A + B)
NAS drive (4) to store tv shows, movies copied manually
I guess the limiting issues is that it doesn't seem like NAS data can get backed up with Time machine so it can only be used as a target. What I mean is I can't use a NAS drive directly because where would ITS backup be?
I thought maybe I could solve my problems with one huge NAS, but that only frees up some space on my existing drive and only gives me a larger backup repository.

Bug report with proposed solution for mounting external drives for ftp access

Hello Guys,   I registered to inform you about something I would classify as a bug. I realized this when I used an external drive with my WD My Cloud and trying to access the drive via ftp. It simply was not visible on the ftp, but was accessible as samba share. I digged a bit in the scripts and found this:  /etc/init.d/mountDataVolume.sh   [...]
## initialze bind mount dir (/nfs)
/usr/local/sbin/updateShareBindMntDir.sh --init
[...]  /usr/local/sbin/updateShareBindMntDir.sh  [...]
init_mounts()
mount | grep -q "${SHARE_BIND_MNT_DIR}/"
if [ $? -ne 0 ]; then
# initial clean up of MNT dir
rm -rvf ${SHARE_BIND_MNT_DIR}/*
fi
for D in `find /shares/ -maxdepth 1 -mindepth 1 -type d -not -name ".*"`; do
share_name=$(basename $D)
add_mount "${share_name}"
done
[...]   The init_mounts() function searches /shares for directories (find -type >d<) and bind mounts these to SHARE_BIND_MNT_DIR (default: /nfs) by calling add_mount(). This is the directory where ftp users will drop in after logging in. The problem: find -type d will not find symlinks and external drives are represented by a symlink from /shares to /var/media/EXTERNALDRIVE I propose adding the following code at the end of init_mounts()   for D in `find /shares/ -maxdepth 1 -mindepth 1 -type l -not -name ".*"`; do
share_name=$(basename $D)
add_mount "${share_name}"
done That will look for symlinks in /shares and call add_mount() for each symlink to bind mount it to SHARE_BIND_MNT. I think this is not intended aka a bug because I found this comment for add_mount(): # - If <share_name> is a symlink to an external volume, then create the bind mount
# directly to the external volume.As it seems from this comment add_mount() supports symlinks but init_mounts does not feed it any.   I tried this solution myself and it works flawlessly.   Yours sincerely,schnip

Nice find!
