Lost USB partition.

A partition on a Mac with a G5 processor running 10.5 intermittently stopped displaying on of 2 partitions on a USB drive with MAC OS extended (Journaled) formatting.
Disk Tools says it is OK.
Tried diskutil and it says it cannot mount it.
When the computer launches it says it cannot mount that partition.
Only thing I have noticed is that there is no mount point identified for that drive.
Have told to mount through terminal and it says it was successful but does not mount.
How do I get the drive to mount?
Thanks

Is it AC powered or Bus powered?

G500 Lost all partitions... :( Cannot install windows 8.1

Hello,
I have lost recovery partition (frankly, all of the partitions...) and tried to install brand new Windows 8.1 from scratch. But the Installer stucks on the first screen - it wants drivers for storage/usb devices. I tried to download the drivers from the lenovo suport pages and there are only binary executables (no *.inf files inside the archive, only sth like setuprst.exe and so), so the installer still cannot find the drivers. I'm totally lost - can someone help me? Maybe you have image of the recovery partition, so I could get drivers from there...
Greetings,
Piotr

I did it. After fours hours and two hours on the phone with Apple support, I installed Windows 8.1 to my iMac. So, I just wanted to share it with you.
System:
iMac 2013, 27" monitor, 1T fusion drive, wirless keyboard, magic mouse.
Software:
OS X 10.9
Windows 8.1 full version 64bit
(I skipped some steps such as type in software key, choose language, etc.)
1. For my last try, Instead of using Bootcamp assistant to setup partition for Windows, I used disk utility to create an 100G space for Windows with FAT file system and named it BOOTCAMP.
2. Insert Windows CD into the USB super drive.
3. Shutdown iMac.
4. While press and hold the left "option" key, turn on iMac.
5. Select CD/Windows icon to boot.
6. Choose Custom installation
7. Select the partition named BOOTCAMP (I am not sure why it is 200G; I assigned 100G. Well...)
8. Format
And the rest is history. By the way, when Windows restarts during installation, make sure to press and hold the left "option" key to boot up Windows.
I do not know why but I am happy now. As a matter of fact, I am sending this message from Windows 8.1 running on my iMac.
Good luck to you.

Lost the partition in Time Capsule

Hi all,
I have a Time capsule from 2012 (the latest model) and I partitioned in the same year: 1TB for backups and 1TB to store my data.
Today I noticed that my Time capsule has recorded the last backup in January 2015 and it is no more partitioned. I did not change anything and now I have lost all my backups and ALL MY DATA form the partitioned part.
Can somebody help?

Firstly a Time Capsule from 2012 is not the latest . It is gen4 A1409.. The latest is gen 5 A1470 and is the tall AC model.. It was released, mid 2013
Next it is not possible to truly partition a TC unless you remove the disk.. did you do that??
If not you partitioned the Time Machine Sparsebundle which is very bad.. or you are meaning something else by partition like you created a second virtual disk.
When you partitioned it.. and now lost the partition.. all that has happened is likely you lost the file name.
Have you done a full factory reset of the TC.. use all short names no spaces and pure alphnaumerics.. for everything.. base station name, wireless name and disk share name.. please do that.. no files are lost with this kind of reset.. if the file is still lost you will have to decide how important recovery is to you.. you cannot recover from a TC.. you need to open the TC and pull out the disk.. put it in a holder and plug into your computer via USB... then run a recovery software.. like data rescue 3.. quite expensive but it has a trial download to see if there is any point to it. You also have a better chance of finding your files.. If it is merely backups.. just make a new one and don't worry too much.
And do not partition the sparsebundle as that is really bad.

Apart from boot camp I had one more partition in my windows, after the Yosemite update i lost that partition.

i had saw loner solved some similar issues who have lost their boot camp after Yosemite update, but my issue is different. i had thee partitions in windows one mac as usual, one boot camp and one i made in windows by shrinking the boot camp partition. but after the Yosemite update i lost the partition which i have made. both mac and windows working perfectly. requesting your suport

Lost USB 2.0 card function and new startup disk issue

I have recently developed a problem with lost USB 2.0 expansion card function after my MacPro awakens from sleep. My Apple USB ports are maintained without interruption. No recent software/hardware additions but maybe a recent OS security download or Apple software update.
My USB card function returns after a reboot only to be lost again by any sleep. On reboot I now notice a ? folder prior to my Grey apple logo and normal startup. This finding occurred at the same time as the USB card issue.
I am running 10.6.8 on a dual core intel Xeon. I had previously lost this same USB 2.0 card function with sleep after a 10.5.1 install. I think it was fixed in 10.5.2 upgrade. Tried resetting PRAM but no change. Could this be a motherboard battery failure?
Any suggestions for me?
John B.

I am experiencing the same issue. And I also had the same problem back at 10.5.1 as you did. I will turn off the sleep function for now, but this is ridiculous!
My system only has the internal (Apple supplied) OEM USB card/ports. Nothing installed by myself. So this is insane to think that this problem keeps popping up. Ever since I updated to 10.6.8, all of my USB connections go down after sleep. But that's not all, I cannot even connect many of our external drives to the USB ports. When I connect them, they power up, but nothing ever appears on the desktop, nor can they be found with disk utility. They connect just fine with every other Mac in our office.
This is all exactly the same as back with 10.5.1, when 10.5.2 came out the problem was solved.
Apple, please fix this!!!

T43 lost USB and freezes

Hi there,
My T43 2668-46U running XP SP3 all of the sudden lost USB's and starts freezing.
For some reason after no problem of 4 years working period a week ago I lost power in all two USB.
Dafter a few days the system after working for around 15 minutes freezes.
I found strange that when I push down a little a touched area it start running but after a few seconds stop again.
I did all (software tool) checks available from Lenovo and results do not show any problems.
Everything is fine in Device Manager - no problems with USB shown.
No more clue what to do.
Any help and suggestion welcome.

The SouthBridge chip is connected to the rest of the board by hundreds of tiny solder balls. As a result of a number of heating/cooling cycles, the connection breaks. Re-balling is done by removing the chip, replacing the balls and exposing them to a proper attachment process. This is not a DIY procedure.
Any T43/p board will work in any T43/p shell. There is one limitation: machines with Intel graphics (model numbers starting in 187x) can't drive a 14" SXGA+ LCD so you'd need a board with ATi X300 graphics chip. Everything else is plug and play.
Good luck.
Cheers,
George

IMac late 2013 lost usb connection after efi smc update

Hi
Lately i purchased a late 2013 iMac with i7 and fusion drive.
After i update to Mavericks and patched new efi and smc update,my mac start to lost usb connectiong when using, from keyboard mouse to my usb sound card, System is not freezing just the usb deviecs. have to press the power button to restart
already tried reset NVRAM and PRAM but doesnt work.

Exactely the Same issue with my iMac 27-fusionDrive3T late 2013, having USB HDs for time machine and data. I contacted the Apple support who propose first level of support: resets SMC, hard reset and so one without success . I did several trials removing hubs, using different USB (3.0,2.0 and 1.0) and changing devices connections(direct to iMac or through USB hub). I succeeded to find a stable configuration puting audio USB speaker directly connected to IMac. When I put this USB speaker through USB huband launch itune music after a certain time all USB chain freeze, and by consequence no more possibility to control the iMac with keyboard, trackpad .... IMac is still working,! The only possibility is to reboot the machine with tne reset button. Hope also this will fixe in the future OSX release!

Lost usb volume

I am sad about lost usb volume.
The hard-disk utility program does not repair it.
A rescue software shows them but does not repair word documents for free.
True?

Yes, the vast majority of the recovery soiftware will show you what they will recover for free but you must actual pay to do the recovery.

How to make an USB Partition Active ?

Is there any direct method available in C# to make a USB partition active other than executing diskpart commands ?

This is c++ forum, no idea about C#.
Using diskpart is just fine IMHO, it has batch mode specially for this purpose.
Note that some USB drives do not have partition table at all, and so no active partition. Diskpart will list these disks as "superfloppy".

Lost usb port in laptop

My wife attempted to update to Windows 10.It totally failed and "lost" the drivers for the usb ports so she can't use her mouse.We spent MANY hours on the phone with Microsoft while they took control of the laptop and attempted to fix it.They finally told us that they think there's some sort of virus on the drive they can't remove???? and that the laptop needs to have something done about the "partition" on the drive.They were not very clear about this, but told us to contact HP.Our warranty is expired. Considering this, if I do a reset to factory original will this correct the issue or has the virus done damage to prevent a recovery this way? Microsoft seemed to think a reset would not correct the problem.The laptop did not come with any disks. We are NOT any sort of experts on computers so we don't understand much of what they were telling us and we had problems understanding the accent of the person who was working the issue.

, Thanks for posting back. Yes in fact if it is proven to be a dead usb port the recovery will not solve the issue. The recovery is to ensure this is not due to a software conflict caused by an update or OS change. It is always the first step to ensure it is not a software issue. The next step is to pull and replace the motherboard if it is 100 percent tested and proven to be a dead port. Here is the link to HP support for repair options if you require that. See if you come up with any issues by running the BIOS hardware diagnostics first though just to see if there is any issues picked up. This link will help you with this. HP Notebook PCs - System Diagnostics (F2) This link will connect you with the correct department at HP support for repair options. Contact HP Support Thanks again for the post and have a great day.

Zenstone 1GB---Lost USB Cord. WHERE DO I BUY IT??

I lost the usb cord to my Zenstone. I can't charge it and havent' found a usb cord that fits it. Does anyone know where I can buy one to fit my zen stone? Most of the ones I saw have a two big ends (you know the ones that fit into the usb slot on a computer. I need one with the usb end (for the computer) and the other for my Mp3 player (small end). Can someone please help

These are actually really easy to find. Many cellphones and cameras use that kind of cable, along with a number of Sony products (PSP, PS3 controllers). The hard part would be finding one as short as the ones that Creative supplies.
Radioshack is a good place to find a wide variety of cables. You should be able to find one at such an establishment

Lost my partition by using DiskUtility in Yosemite

Hi Bro,
I'm newbie in Mac, now using Macbook Pro Retina, with Yosemite Os.
In my SSD hard drive, I have 3 partition that named: Macintosh HD, Data and Temp.
This afternoon, I use DiskUtility to erase my Temp partition because I think this erase partition will be merged with partition before (Data)
So now, I can not use the Temp partition, and can not resize Macintosh HD and Data partition as image attached below
I lost 10GB in Temp partition.
Do you meet this case, and anyone can fix it?
Thank you all

Lost recovery partition and thus windows 7

Through my own fault I lost the trcovery partition and thus my Windows & which came with my E325. Is there a way of getting it?

Hi Praguer,
Welcome to Lenovo Community!
I’m sorry to hear that you are facing the issue with Windows recovery on ThinkPad E325.
Please try to perform the recovery from think vantage button in the system and follow onscreen instruction, if the think vantage button is not working then you have to purchase the recovery media.
However if it works then you can proceed with Think Vantage rescue and recovery.
Please click here to enter the link where you can get the steps for think vantage.
Hope this helps.
Best regards.

Lost Recovery Partition

Dear Sir/Madam
I lost HDD recovery partition some how, if i honest with you i mistakenly format the hdd
is there any way to activate Windows 8.1
Regards
S.M. Jakaria Biddut

Did you create recovery disks when you got the computer, if yes use them. If not, and if you live in the USA/Canada, call HP at this number 1-800-334-5144, and see if you can still get a set of recovery disks. Otherwise the WorldWide site:

Do you know your Windows license key?

How to remove USB partition?

I have an 8GB flash drive which I use for my digital photo frame. I deleted all photos and reloaded more recent ones and once I placed the USB in the frame only old photos which I thought I had deleted appeared.
I then discovered that the USB has a partition that contained the older photos. I deleted these but the USB will only display photos in the one area which has very little space. How can I remove the partition or have the photo frame recognise the other much larger partition?
Please help if you can.

Hi budy,
You can change/edit the partition of USB and all other drives in Windows Disk Managment if you have Vista or Windows 7.
Here is a nice article that can help you do to this:
