Hp v235r flash drive not being detected on my computer

Hi,
I am using hp v235r flash drive for more than 5 years. It's not being detected on my computer since two days. Can any one solve my problem, as there is lot of important data stored in it and hasn't been backed up recently.

Hello budda48,
Its possible the driver for the pen drive is corrupted in your computer, or the drive has met its end of life.
First, confirm that the Pen Drive is seen by other computers. Plug it in to another computer that you havent tried yet.
If it is not working on other computers, then the usb drive is corrupted and there wont be anything else we can do.
If it is working in other computers, then try these steps to troubleshoot the Pen Drive.
Confirm that the port on the computer is not bad. Choose a different port to insert the drive. Next…
Part 1: Make sure that the drive has a drive letter assigned in Disk Management.
Open Computer Management by right clicking on Computer and clicking Manage.
Click on Disk Management. Give it a moment to open the view of the drives installed.
Look for a drive that does not have an assigned drive letter and is not labeled as System Reserved.
Note: System reserved drives are reserved by Windows and will not allow you to assign a letter.
Right-click the unlabeled drive and click Change drive letter and paths…
Click Add and then click OK to select the first available drive letter.
If the Change drive letter and paths… option is not available, make sure that the drive is Online.
If the drive is Offline, right-click the disk number and click Online.
Part 2: If the drive does have a letter assigned and it still does not work, uninstall the driver.
You can safely remove any usb drivers that are not in use (hidden drivers). Devices that get plugged in later will simply reinstall its needed driver again.
Remove the pen drive from the computer if it’s attached.
Right click Computer and click on Properties. In the System window on the left side, click on Advanced System Properties.
Choose the Advanced tab and click on Environment Variables… button at the bottom.
Under System Variables, click on the New… button
Type this in the box that pops up. Variable Name: devmgr_show_nonpresent_devices and also give the Variable Value: 1
Click OK on all the open windows to close them out.
Go to Computer Management again and click on Device Manager. Go to View at the top of the window and click on Show Hidden Devices.
Click on the drop down arrow for Universal Serial Bus Controllers to open the list. Look for any USB Mass Storage Device that is hidden (greyed out) and delete it. There may be several and it’s ok to delete all those hidden USB Mass Storage Devices.
When you connect the pen drive to the computer again, give it a minute to reinstall the driver.

USB Flash Drive not geting detected

I brought HP x705w 16GB USB Flash Drive in the month of October 2014. It is not getting detected in any computers i tried. I tried from DEVICE MANAGER but same problem NOT GETTING DETECTED. It is under warranty period.I visited HP care service near me (Aurangabad) but they are not helping me. Please give some help regarding this problem.

I had the same issue after installing Mountain Lion from the App store. The issue is you are missing the IOUSBFamily.kext extension amongst others. The solution is to backup your macbook, then perform a clean install of Mountain Lion.
I had this done at the Apple Store and now everything is restored as well as performance speed being improved.
Note: When restoring your files (a clean install will delete all your files and applications), use the Migration Assistant.
I would recommend going to the Apple Store to do this because they can perform the clean install from a USB which is so much faster than the download form the App store.
Hope this helps.

Hard Drive not being detected

So my work was giving away old Power Mac G5. They were old and were restored to factory defaults. I wanted to mainly use it for storage. I went out to the store and bought a 1TB hard drive. When I installed it, I got a message saying that the OS couldn't read the hard drive. I figured it was because it wasn't in the correct file format. I went to my disk utility to try format in the Mac OS Extended format. After the two hour format process, I restarted the computer from some other software I was installing. Upon restart, the new terabyte drive wasn't detected. Here is a copy of the Disk Utility log from when I first turned on the system with the hard drive being recognized till when I restarted the system.

As of right now, the system does not recognize the hard drive. I know the connection is good because I have another hard drive that reads just fine. I don't have another place to test the hard drive because I only have an iMac. Can anyone help with this or provide any pointers?? Currently running Mac OS X 10.5.8 Dual 2 GHz Power PC G5.

So I actually seemed to have solved this, to a degree. From what I could read through other help forums, there seems to be a limit on the transfer rate between the system and the hard drive. The OS has a cap of 150 megs/sec, but the hard drive operates faster than that. In order to fix this, you have to put a jumper on pins 5 and 6 on the back of the drive. This was slightly annoying because the hard drive does not come with jumper connectors. I had to find a jumper from another hard drive, and even then, it didn't fit exactly and had to use some strength to get it on.
While it does seem to be operating without any issue now, I still don't understand why it was able to read and detect the hard drive prior to formating.

IDE drives not being detected

Yesturday I built a computer from all brand new parts listed in my sig. However, the motherboard can't seem to detect any IDE drives. It is not crashing, it just says 'None' on the 4 IDE devices. I even tried connecting just the one DVD drive as the primary master on IDE 1 (blue part of IDE cable going into MB and the end going into the drive, middle connecter left open) and it still couldn't detect the drive. I've made certain the IDE cable is the correct way round (it doesn't go in any other way), and i've used a different IDE cable that I know works, but still the MB cannot detect the drive. The drive's jumper is set to Master (i have also tried cable select). JBAT1 on the MB is set to "keep data".
I have seen some odd behaviour that may shed some light. When I do not connect the IDE cable to the drive (so it only has the power in it), the lights come on and the DVD drive tray can open. But when I connect the IDE cable to it, the lights do not come on, and you cannot open the tray, as if there was no power to it. I asked my cousin and he said it sounds like the device is being earthed. Is that possible with an IDE cable?
The second thing I noticed was everytime I started the computer with a cold boot (ie. power down then power on as opposed to reset), it said "CMOS checksum failed - Defaults loaded". I thought this could have been a battery problem so I replaced the battery with a new one of the same model, but it is still resetting the defaults.
Apart from failing to detect the IDE drives and CMOS checksum errors the MB seems to be alright. It correctly identifies the CPU and the amout of memory. The back plate diagnostic connecter that came with the MB says everything is OK.
Any ideas?

Hi guys, thanks for your replies. Its been a busy week and I hadn't got a chance to reply myself.
I've been using the computer for a few days now. Sometimes the drives fail to detect and BIOS defaults get loaded again, but I just loosen some of the screws that hold the motherboard to the case and it starts working again. I am very concerned about this broken wire. It defintely looks like a dodgy board and I am not happy with its unreliability. Check out the pics:
Board (its on the top right)
Close up
I think Ebuyer are gonna be a pain to get this returned to them. I have a feeling they are just going to throw me to MSI support to get it repaired or replaced.
If anyone knows anything about this wire please let me know . Thanks!

USB flash drive not being recognized as a startup disk?

Hi everyone, I've been searching for similar questions but haven't found one that exactly matches my experience. So, I'm going to try and explain my issue in hopes that others may be able to help.
I'm trying to create a bootable flash drive from which I can install lion, and eventually Mountain Lion when it is released onto my main hard drive. My main reason for doing this is to have a way that I can perform a clean install of the operating system. Yes, I know I am old fashioned, but sometimes I prefer clean operating system installs rather than upgrading. In any case, I have downloaded the lion setup file from the Mac app store (Install Mac OS X Lion.app) and am following the directions given on this page to do this procedure. These directions are consistent with directions found on various other sources online. Having this file saved to my hard drive, I was able to find and extract the disk image file from the package InstallESD.dmg to another folder. Once extracted, I plugged in my flash drive and attempted to use disk utility to restore the disk image to my flash drive. I selected the dmg file as my source and the flash drive as the destination. I then clicked restore and was warned that all data on the flash drive would be erased while the disk image was restored to my flash drive. I was prepared for this, so I allowed the process to continue, and it appeared to proceed with no problem. When disk utility was finished, I did a quick look at my flash drive using finder and confirmed that it did in fact appear to contain a disk image of the .dmg file. Here's where things get interesting however.
When I go to system preferences and choose startup disk, my flash drive is not listed as an optional disk from which to boot, only my hard drive ("macintosh HD"). When I restart and hold down the option key, my flash drive is not listed as a startup disk either. I know that the non-intel based macs are not capable of booting from USB, but this is certainly not my issue as I have an intel macbook pro, mid 2009 model. My flash drive is about 4 or 5 years old; it is a PNY Technologies Attaché 16 gb flash drive. I have no trouble viewing and transferring files to and from the flash drive, the only issue is that my computer seems to refuse to recognize it as a startup disk. Are there certain flash drives which do not support booting? This would normally seem more like a computer issue rather than a flash drive issue, but most people seem to have no problem doing what I'm trying to do. Unfortunately I do not have another flash drive with which to test this, and I didn't really feel like buying another flash drive just to test this out if in fact this is not a flash drive issue. I am planning to upgrade to the macbook pro retina soon which of course does not have an optical drive, which is one of the reasons I would like to get this working. Can anyone think of something else I can try? Is it more likely an issue with the macbook pro or the flash drive?
Thanks in advance for any thoughts.

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.
Mount Point : /Volumes/Mac OS X Install ESD Capacity : 16.11 GB (16,106,110,976 Bytes) Format : Mac OS Extended Available : 12.3 GB (12,303,499,264 Bytes) Owners Enabled : Yes Used : 3.8 GB (3,802,611,712 Bytes) Number of Folders : 128 Number of Files : 876

Flash drive not being recognized

My 128 Patriot Flash drive is not seen as potential scratch disk by CS5. I reformatted it as exFAT and then as NTFS but still not seen by CS5.
Thanks, CMA

Check your device manager. I'm sure it's listed as a removable drive and PS only uses fixed drives for swap. If the device offers a special system driver, install it and it may be assigned as a fixed drive, if not, then there's jsut no way to coax PS into using it.

SATA drives not being detected - K8N Neo4 Platinum

I have the same problem, different PSU!
msi k8n neo4 platinum pcb 1.0
3000 64 939
corsair 1gb dual channel ddr400
nvidia 8800gts
antec truepower 550 (19a @ 12v)
used to run 2 ide maxtor 120 and 80
added in a sata dvd writer, worked for 6 months
added in a sata 1TB seagate 7200, sata fails a majority of the time
same symptons now persist as in original post.
:< either bios detects both sata drives, neither, or it crashes. this happens respectively rarely, uncommon, and most common
what ive tried:
updated all mainboard, bios, video drivers to the most up to date (i had to in order for bios to detect the full size of the 1TB)
no ide, same problems
only 1 sata, with and without ide, same problems
the sata only works after a long period of time (or randomly), that i dont use it
(ive had both sata unplugged for 12 hours, booted up this morning with them and it detected, i selected safe mode boot, after making it through a majority of the load, it crashed)
testing a new psu in a day or so, much more powerful. ill give you all my results.

The cables aren't overly bent?
"...worked for 6 months"
"...fails a majority of the time"
Not very relevant, but since i found the FAQs, and there are no less than four FAQs for hard disks http://global.msi.com.tw/index.php?func=prodfaq&maincat_no=1&cat2_no=&cat3_no=&prod_no=165#menu :

E4200 Router my hard drive not being detect on USB after firmware upgrade

I just updated to the new firmware 1.0.02 and the USB stop working for my External Hard WD 500GB harddrive. I had to roll back to firmware 1.0.01 for it work. Is anybody having that problem?

Everyone else seems to be having a problem with the media server. Maybe the fix you're looking for will be on the next firmware roll later this month.

Having a problem with the DVD drive not being recognized by the computer

Compaq Presario CQ60-215DX NOTEBOOK PC, WINDOWS VISTA, Error 10 when trying to reinstall the driver, says cannot start.
I went thru the HP troubleshooting and it said to see the mfg of drive to solve problem! I finally bought a new DVD drive P/N498479-001 for replacement . uninstalled the old drive & then reinstalled the new drive , restarted the computer & it still will not recognize the DVD player! Same error code, same problem. The problem started when I tried to play a CD that appeared to be scratched pretty badly, however my desk top played the CD with out problems? When you click on "computer" the drive does not show up!
I did install a new router a couple of days before this happened, but I am using a data cable to it, so that should not be a problem. Any Ideas?

Apple has moved on from Firewire and the current iMacs (and most MBPs) have Thunderbolt, USB3 and USB2.
There are Firewire toThunderbolt adaptors. Here's one. You also want a four pin to nine pin FW cable to run from your camera to the adaptor.

My Ipod Nano 5th generation is not being detected by Widows and Itunes. I have tried everything based on the trouble shooting tips outlined. Has anyone had this situation before? How was it resolved. My Ipod is just out of warrenty

Have done all trouble shooting tech a through Apples and still have not resolved issues on Windows and itunes not detecting my Ipod nano 5th generation device. Tried restoring the device manually using disk mode and still not being detected by the computer. Device is our of warenty as when service repair charges are $125.00 dolars more than I paid for this device. There must be some way to restore the entire device to factor settings without having to be connected to itunes and Windows. I wish I could connect but again device is not being read. I have another Ipod that is 8GB instaed of 16GB and it works fine. The sad thing about this situation is that my 9year old daughter worked hard doing delivering fliers for a long time to save her money to buy this 16 GB 5th generation Nano. Otherwise the Ipod works well but will not syncronize songs as it is not being detected. Maybe this is a result of corrupt files that got onto my daughters Ipod somehow and thus causing it not the be detwected through the USB connection thus as a result not be understoud as a working device through Windows and itunes. If anyone can help me out there including itune techs that would be well appreciated, but for now my daughter is not able to add new or delete any songs on her ipod as well pictures, and everything. Thanks

Try changing the cord. I could NOT get my computer to recognize my iPod 5th Gen until I read somewhere that different apple devices use different cords. I was inadvertently using my iPad cord and that caused my computer to not recognize my ipod.

IPhone not being detected by computer, stuck in DFU mode. Please help.

My iPhone is not being detected by my computer. I have uninstalled and reinstalled iTunes 3 times to no avail. This occurred during a restore in which the computer lost connection to the phone and left it in DFU mode. Please help. I also must add that my lock button is broken as well.

If your button is broken there's probably no way to recover the phone. You will need to get the hardware problem resolved first.

USB Flash Drive not detected after OS X Mountain Lion installed.

My MacBook Air 11 inch (Mid 2011) suddenly stopped detecting all my USB flash drives a week after upgraded to Mountain Lion.
I have a tiny 16GB USB flash drive (Sandisk Cruzer Fit), for daily work, that has never been unplugged from my MBA.
Everything was fine on Lion, and a week of Mountain Lion, until just when my MBA prompted me that my flash drive "was not ejected properly" after I re-opened the display/lid, or from sleep mode.
I thought I might have accidentally removed the flash drive unknowingly. So I tried re-plugging the flash drive, closed and re-opened the MBA lid, and the same error message "The disk was not ejected properly" occured. I repeated the steps for a few times (thinking my flash drive might be faulty) and at my last attempt, the flash drive was stopped detected. I tried several USB flash drives and external hard drives (of various brands) to both the USB ports of my MBA, only the external hard drives were detected (on both USB ports) and functioning. None of the flash drives was detected on either USB port.
The tested flash drives were plugged to another 13" MacBook (Unibody, Late 2008, OS X Lion) and they all worked fine.
I wonder if anyone faces the same problem, and solution(s) please?
Additional: OS X Mountain Lion re-installed and same problem occurs / No problem with OS X Lion.

I had the same issue after installing Mountain Lion from the App store. The issue is you are missing the IOUSBFamily.kext extension amongst others. The solution is to backup your macbook, then perform a clean install of Mountain Lion.
I had this done at the Apple Store and now everything is restored as well as performance speed being improved.
