Why does my MacBook Pro not find USB hard drive after waking from sleep?

is this a known issue? i have to manually turn off/on the Mac's Airport to re-establish USB HD connection (or Time Machine won't find it either).

I hate to have to tell you this, but backing-up that way is "iffy" and *+not supported by Apple.+* See [Using Time Machine with an Airport Extreme Air Disk|http://web.me.com/pondini/Time_Machine/Airport.html] (or use the link in *User Tips* at the top of this forum).
It sounds like you're using that disk for other things besides your backups; if so, and if you're going to continue backing-up that way, it really should be partitioned so Time Machine has it's own, exclusive space. See #Q1 in the same link.
Time Machine should find it's partition when OSX wakes up; if it doesn't, try a "full reset" of Time Machine, per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).

MBA not connecting to network drives after waking from sleep

I have been having this problem over the past few days. When my lat 2010 MBA wakes from sleep it will not connect to my NAS. If I try to force it too connect finder will crash and I get the cannot find finder.app error -10801. The only way I have been able to get the MBA working is a hard reset. Then all is well until I close the lid and wake it up at some point.
I was thinking about re-loading SL, but thought I would check here for any thoughts on this problem.
Thanks
Jim

Hi Carl,
This will fix many problems AND clean up a lot of useless stuff.
Get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, boot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
One other "Wake" problem... ignore the HW and other symptims because it works in many other situations...

HT4790 I can not find my hard drive after encryption

I have a macbook pro I upgraded to Mountian lion from 10.6.8.

Uninstall the program. It should have come with an uninstaller. If not, contact the developer for instructions.

Lose connection to external USB hard drive after waking up from sleep

My Mac lost connection to the external USB hard drive after waking up from sleep. I can still see the folders in the hard drive in Finders, but when I double clip a folder no file within the folder is displayed. I have to reconnect the hard drive with iMac to read its contents.
May I ask how this happens and is there a solution?
I'm using Paragon NTFS for Mac OS X to read from and write to NTFS format of USB external hard drive.
Thanks!

... I un-ticked the "put hard disks to sleep when possible" option in the Energy Saver panel in the System Preferences, and it seems the problem is solved. will have to sleep and wake up my iMac to further verify if this is the solution ...
Alternative advices are always greatly appreciated!

Macbook Air 2014 Black Screen w cursor after waking from sleep.

I just purchased a brand new macbook air this past week. I noticed within the first day of using that if my machine went into sleep mode, and I hit a key to take it out of sleep mode, it would go to a black screen with my cursor for about 30 seconds.
It does not do it every time but enough that it is annoying. I am coming from a mid 2011 mac air that did not have any issues. (only replaced for all day battery)
Do you think this a hardware or software issue? If i swap this mac out do you think I will just encounter the same thing?
I have read numerous posts regarding waking from sleep issues but they all seem to be affecting MacBooks purchased between 2012 and 2013.
Any help would be much appreciated.
Nick

UPDATE:
I called apple tech support and after talking a bit decided best course of action was to replace the macbook air as I was inside my 14 day buyers remorse.
I came home and hoped all was well when this one began doing the same thing. I made an appt with the genius bar to dive further in to this and we did a complete wipe on the computer and reinstalled the OS. The "genius" said I'm probably bringing something over from my previous mac air. (even though it never had this issue).
So after completely reinstalling the OS and setting up my macbook as new I pretty much lost all my settings and what not accumulated after 3 years with my previous mac. They did use Time Machine to at least bring my iPhoto library over and iTunes music.
It has been exactly one day since this was completed and the computer is doing the exact same thing. ***!!!

Why does my MacBook Pro not boot up with the Snow Leopard Disk?

I have erased the entire hard drive on a 2011 macbook pro that had snow leopard on it. I was corrupted. I not insert my Snow Leopard Disk and the machine will not boot. I chose target mode to erase the hard drive from my mac book pro with Mt. Lion on it.
Thank uou for any help,
Ken

Target mode? Is there a second computer involved? Why not insert the Snow Leopard disc in the computer on which you wish to install and hold down the C key to boot from it?
If the disc came with a different computer it will not boot another model. Retail discs also may not boot all model computers, even those that came with the same major version. For example, some MBPs came with 10.6.6 but a retail disc may only be 10.6.3.

Why does my macbook pro not start up?

Today I changed ram on my old macbook pro. 667hz DDR2 type from 2X1 TO 2X2.
After i finished the installation my laptop has not worked properly. It currently runs 10.7.
No startup sound, and the white light at the bottom flashes constantly in sequenses of three. Three quick flashes.
What is wrong? Even when I re-inserted my old RAM the same problem occurred.
Please help!

MacBook Pro 3,1 15' 2,2 Core 2 Duo Late 2007.
I used the same buss speed (667 mhz) and the same type DDR2. Same number of pins.
I also checked what happened with 0 ram in slots, and then it started blinking constantly.
So it must see the RAM but the RAM seems useless for some reason...

Why does my macbook pro not have an apperance tab under display

I am trying to connect my macbook pro to my tv to watch Netflix via an adapter and HDMI cable. I went into Display to go to Appearance and turn on mirroring but I don't have an appearance tab under display. Is there somewhere else this would be?

Thank you very much but now I have another question. I plugged in my adapter to my computer, plugged the adapter into the HDMI cable, plugged the HDMI Cable to my TV. I have tried the Detect displays button after I changed my TV to the HDMI source and Before I changed my TV but I still can't get my computer to detect any displays. Do you happen to have any suggestions?

Why does my macBook PRO OS 10.9 reboot when it goes to sleep mode?

Sleep – Slow Wakeup/Requires Reset

Why wont my macbook pro boot with external hard drives connected?

After two years of uninterrupted success running my MBP with five external hard drives attached (two USB, two eSATA with LaCie Expresscard 34, one FireWire 800), my MacBook Pro with Mountain Lion 10.8.2 installed will not boot with the drives attached. Starting up with the option key depressed does not work. Anyone have insight? This didn't happen until I upgraded to 10.8.2, so is there a bug fix needed in that update?

Update, I reset the PRAM (i think) and now the chime is back as I start up... small win but thats all it does.
So I decided to dload a copy of Lion and burn to a disc, then try and boot from there. When i boot holding option and select the dvd it sounds like something is happening, contstant turning or reading of the disk, but nothing is happening on screen, just my old friend the apple logo and his mate the spinning wheel. Starting to concede now, just hoping to get my data back, its mostly photos and some files i cant duplicate.
I am going to purchase Mountain lion on my current apple ID using a friends macbook and try and reinstall from there. Although i never had Mountain Lion installed in the first place (just lion) there isnt an option to buy lion on the app store (i dont think) This is prob my last spin of the dice i think before handing it in, unless anyone on here has some ideas....

Can not find USB Hard Drive with Airport Utility Programme

I am quite new to MAC and I am having difficulty making my Iomega External HD seen by the Airport Extreme Base Station (new version). I have the latest Aiport Utility software 5.2.1 but when I go to the hard drive section it does not see it. The drive is connected via USB. Can anyone help me please.

Hi, this could be caused if the hard drive isn't in the right file system. To make it work, it needs to be formatted in a 'MAC OSX EXTENDED' format. You can do this in Disk Utility if you connect the drive directly to the computer and go to applications/utilities/disk utility.
Another question that may be asked this external hard drive, does it have its own power supply? If it does it should be ok, but some small portable thieves power which the router probably wont provide. If this is the case you can sort it by getting a powered USB hub (which don't cost much).
Another issue you might come across was a bug I found if you give the Hard Drive a name and connect it to the router and it appears and the next time you unplug the router power and connect it again it sees it but you cant connect to it on any computer over the network, the hard drive name needs changing every time you unplug the router, its a silly bug but im glad I finally worked it out.
Also, Airport Utility has a new software update, so have a look for it, should be 7.2.1 now!
Let me know how you get on!

Macbook pro not detecting my hard drive

I have been using this 500GB WD Hard disk and it has been working properly. However, it is not being detected today when I plugged it in.
I have tried methods like "automatically fixing errors" at PCs and checked it on Disk Utility, unfortunately it is still not working. I have important files in it and what should I do?
Thanksss x

eww's suggestion may seem a bit rash, but I've found that to be the case also. My WD external's enclosure also fried.
I bought OWC's FW hard drive encloser. You can put in your own drive(s) (I bought Seagate drives from OWC) depending on whether you want a single drive backup, dual or RAID. I bought the OWC Mercury Elite...great enclosure rated top in all my Mac magazines. What's nice about these is, if the drive goes bad you can replace it yourself and not have to get rid of the whole unit (like what happened to my Western Digital FW Ext. drive last time!). OWC's enclosures have Oxford chipsets which are totally Mac friendly. They also work for Windows machines. OWC also backs up their products...no arguing involved.

Help? Can not find external hard drive after upgrading to 10.6.3

I upgraded my iMac to Snow Leopard 10.6.8 and now my external hard drive does not appear. Not sure what to do.

It is powered (the light is on). I was uploading photos from the drive yesterday, so it worked perfectly fine before the upgrade to 10.6.8 (which I did during the night). Is there anything else to try before I move it to another computer to see if it works? Again, thanks.
