T420s wireless driver problem - after restore/reinstall

i have a 420s that works fine.
but something went strange with the wireless after one of the updates, not sure if it was windows or lenovo update.
in any event, i tried reinstalling the driver, and it stayed broke. so i rolled back the computer to a week or so earlier.
this fixed the wireless, but broke a few other applications not lenovo related.
after manual updates on those programs everything works again.
so fast forward to today. i did the lenovo update, and it decided that it needed to update the intel wirless driver package, since it was never installed. **bleep**? but i figured how bad could it be, AFTER i set a new restore point, so the only thing that would get restored was the wireless if it went strange on me.
after the update, wireless broke again. not entirely sure what was wrong, but it just didnt work right and wouldnt connect or see some known access points.
question; what is the proper method to completely deinstall/reinstall the wireless drivers and 'access connections' on this computer so that everything works properly?
thanks for any insight
mark

hey markgca,
try uninstalling the wireless driver. let windows install its own generic drivers.
test again with the generic drivers.

T420s Wireless Connection problem

Just moved into a new place and we are splitting wireless with the person who is in the apartment next to us which means I don't have access to the router itself.
Everyone in the apartments computer has managed to cnnect to the wirless router and input the commercial including a dell, three macs and several ipads. My t420s is the only machine that has been unable to connect to the network or even reach the point where I can enter the password.
I can connect to every other network I've tried but this one.
Any thoughts?

First of all please check the Wireless is turned On or not by pressing Fn + F5.
Also check that the Wireless switch on your system should be turned on.
If the Wireless is already turned on and still unable to search the Network then please check the driver in Device Manager Please uninstall the Wireless driver under Network adapter. After that please download and install the Wireless driver from the below mentioned web link as per your Operating System.

Please check the issue after reinstalling the driver.

Time Machine problem after restoring to a new HD (after my original HD failed)

I am running Lion 10.7.5 on a MacBook Pro Late '11
My HD was getting SMART errors, so I did a complete back up using Time Machine using a WD My Passport 1TB external, and then sent my MBP to Apple for HD replacement (under my Applecare plan).
I collected it yesterday and restored my system using Time Machine (using the data from my external HD) and everything was restored perfectly, which was great,
However, I'm now encountering a problem after plugging my external HD back into my MBP on the new system. Rather than Time Machine doing a swift 'top up' back up, it appears that TM is attempting to do a full back up. (I have 300GB and it took nearly 24hours to backup on the faulty drive) Is this normal after installing a new HD? Bearing in mind the Time Machine data is still on my external drive?
It's also appearing to be taking FOREVER to do this entire back up again. It is stuck on 'preparing back up' and when I do get some movement, it's doing a couple of KB's at a time and with no genuine back up progress.
Fundamentally, I just want to just top up my Time Machine back up without having do a complete back up, again. (which doesn't actually seem possible, viable at the min)
Any help / support would be much appreciated

AFAIK, it'll do that since the HD has a different UUID and the old TM backup won't recognize it. See Pondini's TM FAQs, for starters.

Problems after restoring iPhoto library

I have had a number of problems with iPhoto since restoring my photo library after a hard drive failure. Apple replaced the hard drive and I restored the photo library from a DVD backup.
The problems with iPhoto are:
1. When attaching my digital camera to import new photos the import goes OK, except the new photos are not added as a new film roll. They are placed (seemingly randomly) in a film roll that is 2 years old.
After this if I sort the library by date they appear at the end (as would be expected), but if I quit iPhoto and reopen it later the newly imported photos are gone. iPhoto prompts me to recover missing photos when I open it and it does so, but the recovered photos are just file numbers and grey-dashed boxes -- no actual photos.
2. iPhoto has started moving photos from years ago to the end of my library (ie the most recent) and re-dating them with todays date.
I hope I have explained my issues adequately, they are making my head spin!
I would very much appreciate any advice.

M&C:
I trashed the iPhoto Library File on the desktop
What file would that be, the Library6.iPhoto file? If it were on the desktop then it would not have any effect on the library. That's the file that can get corrupted for a number of reasons, some of which seem to come out of the blue. It's usually due to an interruption while that database file is being written to and it's left open and, thus, damaged. Users have reported it going bad after shutting down for the night and the next day it's gone bad.
For that reason I suggest you look at the tip at the end of my signature for a way to protect against it.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file. You can put it in the Dock and click on it after every import or any extensive editing/organizational effort in the library. You want iPhoto dormant when you make the copy.

Optical drive problems after upgrade to Tiger 10.4.10

I've just had my machine updated to Tiger 10.4.10 after having two new hard drives installed after a hard drive failure. I'm now having issues with burning data for backup purposes.
I can't burn anything with Mac OS Disc Burner utility, it doesn't seem to recognize blank disc's DVD's or CD's. It keeps telling me to load a disc when one is already in the drive.
System profiler recognizes CD-R's & DVD-R's when they are in the optical drive
I can burn with Toast Titanium ver 6.0.3 DVD's & CD's. The burned CD's will mount. The burned DVD's will not mount.
I have checked the burned DVD's in the optical drive of my iBook G4 Mac OS 10.3.9 and they mount on it fine.
Movie DVD's will mount & play. Software DVD's will mount and load applications.
I have cleaned the drive with a cleaning disc.
The Optical Drive was working fine before the upgrade, so what is the problem?
I can only assume two problems now!
1.) the optical drive has a physical malfunction
2.) there is a software issue between Tiger 10.4.10 & this optical drive (this is my favorite at the moment)
The upgrade was done by an Apple Authorised Service Provider they say there are no issues with Tiger & the optical drive.
So any ideas or help would be much appreciated.

I'm having a similar problem. I bought my G5 with Panther OS on it a few years ago. The DVD drive functioned perfectly back then. Then I upgraded to Tiger this past year which caused the DVD drive to open later..that is, I'd have to hold down the eject button for a good 2 or 3 seconds before it would open or close. Previously it responded instantly. Now what happens more and more is it can't read DVD-ROM disks that it has burned. My imac G4 with Jaguar has no trouble reading the disks but Tiger 10.4.9 and 10.4.10 simply refuse to mount DVD ROM disks that it burned.
I'm trying to make a duplicate DVD of the offending disk on my single-processor G4 and then put THAT disk into the G5 so it can read the info. Hopefully that will be my work-around.
It's got to be a software issue and I keep hoping the Apple wiz kids will put out an update to remedy this. Something's fishy with the DVD drive programming.

Serious external drive problems after installing Mavericks

OK, so now I am seeing multiple external drive problems. Here is my setup: A GTech 4TB drive connected to MacBook Pro via Firewire, formatted of 2 partitions of 2TB each (called GT1 and GT2). This is then daisy chained to two WD drives of 2TB each, called WD1 and WD2.
After installing Mavericks everything worked fine (in fact I have an amazing speed increase). However, after restarting my machine this morning I have the following issues:
The GTech is now a single partition called MyBook (obviously a hangover from the WD drives. I suspect the WD drive managment software) with NO data files. Interestingly it shows the following USED 1,106,870,272 bytes (1.11 GB on disk). This suggests that one of the partitions has disapeared completely.
Whilst WD 1 launces ok, WD 2 causes the Finder to relaunch whenever selected, meaning I can't get to the files. I remember having this problem before when I upgraded to SL, and it having something to do with hidden files that needed to be deleted via the terminal. However, I have searched the web and can't find the solution again.
Given that WD 1 and 2 are my backups of GT 1 and 2, then I now have a situation where I cannot access my primary or backup files for GT 2. Very impressive - not!
Can anbody remember the hidden file solution for the finder relaunch?
Can anybody help me get back my GT1 and 2 partitions (as they have the latest work on them)?

FIrewire & Thunder bolt drives are having issues with Mavericks, avoid same until a fix is issued if you can.
many are reporting same, there is a firewire fault and TB HD on external HD from LaCie (Seagate) and from WD especially.
Technicians are looking into it.
Until there is resolution, consider setting up a USB ext. Time machine HD.
Until then consider confining Mavericks use with USB HD.
Ive tested a very long line of USB HD on Mavericks, all seem fine.
Recommend anyone DO NOT ATTACH any WD MyBook externals (firewire, thunderbolt or otherwise).
I dont have same to test, so I dont know if the problem is in the firmware on the SATA bridge or if its a problem with the WD software

Drive problems after OS install

Just installed OS X Leopard on a partition of a new internal drive. After an app freeze and hard shut down (holding power button for 5 seconds), and after booting back up, another internal drive would not appear on desktop or in the drive utility. The missing drive was partitioned into two halves, and neither partition appears.
Is there firmware that needs to be installed on the drives themselves for Leopard to use them? And more importantly can the drives be recovered?
I did look up firmware topics on Apple support and the G4 MDD was not listed as needing a firmware update.
Thanks in advance for any assistance.

Then, you don't need a firmware update. Restore your 10.4.8 installation, update it to 10.4.11, and try the Leopard install again.

T 61 - Hard Drive problem after attempt to restore laptop to ex-factory situation

Hi all
I have a T61 Type 7664-17U from 07/10 bought at a charity auction. It came with all the disks to reset to ex-factory situation. Worked nicely for almost a year the sound indicating that there was no drivers for it. Went to Lenovo site, got the correct driver and tried to install it.
A message came that only part of the request was executed, still no sound and no driver. I log off to sign up as administrator as it could be lack of "authority" so to speak, just to discover that the person that bought it for me and installed some software he had allowed himself to set up a password for "administrator".
No other passwords exist anywhere.
Because the T61 came with lots of software that I do not use and that were just slowing it down, and also because it came from other "hands" and including for security reasons I decided that it was time, to clean the entire hard drive to ex-factory situation.
Used all the disks and everything went well until after all the disks were run and inserted the "Supplemental Disk" in the end a message came up.
No AOD file found
After auto restart was made I was instructed:
"Click next to begin Recovery Process"
then
"Preparing Hard Drive"
The laptop freezed for about 3 or 4 seconds and proceeded again on its own but the hard drive was not formatted, simply no time for it.
New auto-restart
Then a message.
"No Hard Drive Present"
Now, on a 160 GB Disk, I can only see a single partition of about 6 (six) gigabytes named SERVICE 0001
Couldn't find a way around this problem.
Can anyone help me and tell me what might have happened and how to solve this problem ?
Buying another disk is simply not an option at this time.
All the best Stilicho

Hello,
Have you tried erasing or wiping the disk using whatever tool the hard disk drive manufacturer provides, and then performing a clean install from the recovery media? If so, what effect did that have?

[SOLVED] More rsync problems after restore... Read only filesystem?

Yesterday I backed up all of my data with rsync to a USB thumb drive. Surprisingly it all fit, but my intentions were to wipe my disk and create a new partition scheme for a dualboot while still being able to continue where I left off with arch. So after backing up with the script from the arch wiki titled full system restore with rsync, I followed the rest of that page, and modified the fstab on the backup on the USB and reconfigured grub and restarted my computer and I was able to boot into the USB. Then, I decided that it would be easier to just use the live cd to repartition and pacstrap the base system and generated an fstab. Next, I chrooted from the livecd environment into the newly built base and installed rsync. I then mounted my USB to /mnt in the chrooted environment and used
rsync -aAXv /mnt/ARCH_BACKUP/* / --exclude={/mnt/ARCH_BACKUP/etc/fstab,/mnt/ARCH_BACKUP/boot/grub/}
I just did this since I figured that all of the directories excluded in the script wouldn't really have to be excluded here since they were already empty. Everything seemed to run smoothly except for one file(or maybe directory?) called /etc/resolv.conf.t.jbnW2 which kept giving an error. I figured the file was unique to the USB or something and continued to reinstall grub and then reboot. The weird thing is that everything was back on my system, but it didn't automatically boot into a display manager which it's set up to do. Then when trying to manually start x, that wouldn't work. Then I tried to connect to wifi, it recognized my network but wouldn't connect, so I tried sudo su, which worked but returned an error that the var file system was read only. I then tried to use rsync again thinking maybe that directory would transfer now that I wasn't in the chrooted environment. But instead, it was trying to restore every single file, but every one returned the error "filesystem is read only".
It seems like when I restored all of the files in my entire system were made read only.
Can anyone tell me what may have caused this and how to fix it?
I think it may either be that when I mounted the device in the chrooted environment I didn't specify 'rw' capabilities, or it may be that when I backed up I didn't specify 'rw' capabilities I just opened the file manager and clicked on it and it automagically mounted to /media/.

Ok, well I fiixed it. I had edited the fstab on the usb to be able to boot into the usb, and, while I edited it again on the hdd each time I restored from the backup, I didn't realize that the top entry /dev/sda1 (which is my root partition) was on a line that was commented out. I guess I accidentally hit the backspace button or something while editing it to be able to boot into the usb.
Also, I think there was a second problem, that my usb controller is starting to fail. Because on the last time that I backed up, if I moved my computer or anything I would get a I/O error. This was caused by the failing usb controller. The computer would remount it as read-only because of the failure. The solution to this was to use
hdparm -r0 /dev/sdxy
Note: The device must be unmounted.
Where x is the device and y is the partition number, for me this was sdb1.
Then mount specifying read-write option.
mount -o rw /dev/sdxy /media/<BACKUP>
I also tried
mount -o remount,rw /dev/sdxy /media/<BACKUP>
as was recommended on all of the sites that I could find, but this command kept returning an error.
Note: For newer users, Arch does not automatically create the media folder as it doesn't provide automatic mounting of external drives. If such is the case, and you haven't installed a desktop environment with a file manager that will automatically do this for you when the device is recognized, you must make the media directory and the directory which you intend to mount to manually.
# mkdir /media
# mkdir /media/<BACKUP>
Where <BACKUP> can be whatever you want it to be.

Time Machine Problem after restore

I had a hard drive crash, and after repair, I restored from a time machine back. Everything seemed fine, although a few sets of photos were missing from iPhoto. After things seemed to be fine I have started doing time machine backups again.
My problem is that they take a very long time to complete. I expected the first one or two to take a long time, but not since then. I have given it weeks to make sure that it has had enough time.
Every single time the verifcation stage shows 10s of thousands of files. Even if I have not made any changes. In my console log I see:
6/7/12 11:17:34 AM
com.apple.backupd[61578]
Node requires deep traversal:/Users/dersh/Pictures/iPhoto Library reason:contains changes|must scan subdirs|fsevent|missed reservation|
For every single backup. It seems like it is not actually fixing this. From googling around, I expect that this should take a long time the first time or two, but then should finish. It then says that it is backing up about 600 meg. The exect number seems to change with each backup, depending on what I am doing, and what changes I have made. But even if I do nothing, it still is in that range. It then appears to complete, although it takes a long time. I would guess that since it is doing the deep traverse it then has to match up a bunch of files, so doing the actual backup takes much longer then it should. For example it might sit for a good few minutes at "backing Up: 105.2 MB of 580.2 MB" Then it moves on to 107.6. Finally, the cleanup takes a very long time. So overall each backup is taking 10s of minutes. Even if I am not doing anything with the computer.
I am using a firewire drive directly connected to the computer. I have done a repair of the external time machine drive, and have done a verify of the internal drive, with no issues.
I see that I have plenty of space on the external drive.
So, it seems like what is happening is that it doesn't "know" that it has done a succesful backup of iPhoto, each time so it does a deep traverse and then backsup something like 600 meg of data from there. How can I get it to "understand" that it has done this? Can I force it to do it once correctly, so that it will take?
Any other suggestions?

UPDATE
Happen to have a QNAP NAS from work at the house which has Time Machine support and can select and initiate a backup there, no problem!
So, it's something about the Mac Mini or drive? I didn't do anything to the Mac Mini in the process other than removing the USB drive and plugging it back in.
As far as the drive, I dumped it and re-partitioned it with two partitions one for the Mini and one for the iMac. The Mac Mini is backing up to it locally, no problem.
