Mass Storage totals around 14.5GB, where it was ad...

My Mass Storage Totals around 14.5GB, my N8 should have 16GB, i know that some size are unavailable for storage but it was a loss of 1.5GB, is this normal?
Solved!
Go to Solution.

Perfectly normal, all phone, computer, hard drive, memory card etc manufacturers do this and have been doing it for many years now.  It's industry standard that memory is listed at it's unformatted sized.
When you buy a 500GB hard drive and format it you don't end up with 500GB of usable space, you actually get closer to 460GB. Last year I bought an 8GB ipod touch, in reality due to this "standard" and the space used by the OS I have closer to 6GB of usable space.

  • Satellite M100 - Driver for Mass Storage Controller

    Please help. I keep getting the message hat I have no driver for my Mass storage controller. I have downloaded and re-downloaded the Toshiba drivers. Microsoft cant find anything.
    It seems to be PCI bus 5, device 6, function 2.
    Can anyone help (in laymans terms please). This is driving me crazy.
    Thanks

    Hi Tellgio,
    Which Toshiba drivers you have reinstalled exactly? Im pretty sure that you dont have installed all drivers because you still have a yellow exclamation mark in device manager
    Furthermore it would be interesting to know which OS is installed
    I had also a yellow exclamation mark on Mass Storage Controller and in my case it was a missing Card Reader driver. So you should install this driver from official Toshiba website:

  • Windows 7 Installation problem: "no drives were found, click to load driver to provide a mass storage driver..."

    I just purchased a Toshiba Satellite laptop (U945-S4140) that came with windows 8. I am trying to install windows 7 enterprise 64 bit.
    I have the installation file on a bootable USB stick. In order to boot from the USB, I have to go into the BIOS settings and change from UEFI to CSM boot mode. Then the computer will boot from the usb stick and the windows 7 installation begins to work fine.
    However, I soon get an error message that "no drives were found. click to load driver to provide a mass storage driver for installation."
    I cannot figure out how to proceed. Any help would be greatly appreciated.
    Cheers

    Hello Maxxpower33, thank you for your words.
    I looked through the error logs that could be generated from the tool and found this one which may be what you experienced.  Kindly let me know if this is what you got:
    "Files copied successfully. However, we were unable to run bootsect to make the USB device bootable. If you need assistance with bootsect, please click the "Online Help" link above for more information."
    Some further information is that I found this post where another user experienced the same error on a laptop, although the speculation mentioned in the post is that the user does not have a Windows store account under which he purchased the license for Windows
    7 Home Premium, which is the flavor he was trying to get on the bootable drive.  However, this does not seem to be a valid response due to the fact that the tool does not check Windows XAuthCert Servers for validation on licensing.  So ignore that
    portion of the post, but the 2nd post helps a bit by linking to another article, providing both below.
    Forum Port With Same Error
    Article with 4 methods to create
    a bootable Windows 7 USB Drive
    In that first post, further down, is another reply to a tool that I have not tested with.  So please use caution on this one as I cannot find very much feedback other than on their own website, but sounds much like the first tool I mentioned in my first
    post "Unetbootin", but this one is called Rufus, and two people did mention they had good success with this tool after having difficulties with the Windows utility.
    Rufus
    After all that is said and done, there is not 1 tool that will work for everyone all of the time on every environment.  Why?  I would like to know also...but speculate hardware/firmware/bios combinations could be the culprit.  One of these
    tools should work for you and it would be my recommendation to try them in this order (skipping what you've already tried):
    1) Windows 7 USB/DVD Download Tool
    2) Unetbootin
    3) Manually creating the partition and xcopy'ing the extracted ISO to it
    4) Rufus
    5) Borrow a PC with a DVD-R in it and burn the ISO to a disc and install from it.  If your laptop does not have a DVD drive, an external drive can be purchased for roughly $25 or less.  Or if you have an internal drive laying around, buy an enclosure
    for about $15 and put the drive inside there and attach it to your laptop via USB or eSATA.
    As always, my advice is nothing more than my opinion, which are like bungholes...everyone has one and they all stink!  LOL!

  • USB Mass Storage Mode Missing :-(

    I just upgraded? to the Samsung Galaxy S III today and have been very happy for the most part.  However...
    I am EXTREMELY disappointed that the only options to transfer files to the phone/SD Card are to use the MTP and Photo protocols.  I always loved my Android phone...built off of open source software...and using open standards (things like USB Mass Storage).  It is incredibly useful to be able to plug my phone into almost any PC, running any OS, and be able to transfer files to and fro.
    Where is the rest of the uproar?  When are we going to demand that one of the most useful features on our phone be put back.  It was already there...it was already working...and has been dropped for lame, limited use protocols...  Why?  Who is getting paid off?  Why? 
    Bring back USB Mass Storage Mode!!!!

    It is always a good idea to do some research...  I have followed your suggestion and found that Google has two reasons for using MTP instead of USB Mass Storage.  They  are:
      1)  “A main reason for using MTP rather than for example the USB mass-storage device class (MSC) is that the latter operates at the granularity of a mass storage device block (usually in practice, a FAT block), rather than at the logical file level. In other words, the USB mass storage class is designed to give a host computer undifferentiated access to bulk mass storage, such as compact flash, rather than to a file system, which might be safely shared with the target device (except for specific files which the host might be modifying/accessing). In practice, therefore, when a USB host computer has mounted an MSC partition, it assumes absolute control of the storage, which then may not be safely modified by the device without risk of data corruption until the host computer has severed the connection.“  -sombody from Google
      --My Response - "I am totally OK with the SD card not being safe to be mounted.  During the time I choose to be connected (only when transferring files)...I DO want the PC and not the phone to be in complete control of the SD card."
    2)  “MTP is a big improvement over USB mass storage — for devices with lots of internal memory, a manufacturer no longer needs to come up with some hard partition between the USB mass storage and internal storage. Instead, they are all in one partition, with MTP providing access to the directory of media files that would normally be available through USB mass storage. This means there is no longer a need for apps on SD card for such devices, because what used to be the ‘internal SD card’ is in the same partition as where applications are stored. The storage on your device can be used for either applications or media, depending on what you want to put on it. You aren’t stuck with how much space the manufacturer decided to leave for the two areas." -somebody else from Google
      --My Response - "I am completely OK with the removable SD card being treated separately.  That is EXACTLY what I want.  I want to keep MY DATA separate and only on the removable SD card.  And all of the stuff that I don't care about...that can be easily reinstalled (apps and such) on the internal memory.  It is a good design.  The phone has enough internal memory that I don't have any trouble with space for Apps (so not a conern at all)."
      --My Overall Response - "The loss of flexibility, portability, and usefullness does NOT come close to justifying removal of the USB Mass Storage protocol.  I am still VERY disappointed."
    Where is the THUMBS DOWN... and INCORRECT ANSWER?

  • Broken screen but need to enable mass storage mode blind

    Hi there.
    I have a Curve 8900 with a broken screen. I have connected it to Blackberry Desktop Software to get anything I can backed up. It appears to backup all application & organiser things, but wont let me sync music, pictures, or videos.  Troubleshooter suggests that it's because I haven't enabled Mass Storage, but obviously I cant see the screen to see if prompts me to enable it. I have tried connecting my phone and randomly scrolling to see if I can click "yes" to enable it by chance, but it is just as likely that I have clicked "do not ask me again" and then clicked "no" as well.
    Can anyone guide me through the long way of going into settings and changing it manually, bearing in mind that I cannot see what is actually happening? Or does anyone know a way around it?
    Also, my menu was exactly the same as when I originally got it, with no added icons. I seem to remember 'settings' being on the last row but not at the very end. Thanks.
    UPDATE- ok i've worked out how to get into settings, but can someone tell me how to get to Enable Mass Storage mode from there? Like either how many rows to scroll down etc, or if pressing a letter takes me to the correct option, and then where from there?

  • Canon Vixia HF R400 - USB Mass Storage?

    I recently purchased a Canon Vixia HF R400 and was wondering if there is a way to make the camera appear as a USB mass storage device (like an external hard drive or flash drive).
    When I plugged in the camera using the provided USB cable to a Debian (Squeeze) system, Shotwell Photo Manager appears as an option but it never successfully gets any data.
    I've looked through the manual but found no reference to USB mass storage.  Am I limited to Windows/Mac for accessing the files via USB?  That would sad, as I have neither available to me at home.
    Thanks in advance!

    FYIGMO63:  I'm using Linux -- Debian (Squeeze). I don't own a Windows nor a Mac system.
    I've seen mention of other models of camcorders where the user is apparently asked to select their USB mode, but my camcorder doesn't seem to prompt for that.  I poked around the settings menus as well and didn't find any where to specify USB connection mode.
    Just so that I'm looking in the right place, could you give me an example for how you would do that on your camcorder (and what model you have)?
    It would REALLY be nice if a CANON representative could look at this thread and tell me what I might be doing wrong to mount the camcorder as a USB Mass Storage device ... or if it's even possible under Linux.
    I have 6 days left to return it at BestBuy, which I'd like to do if I can confirm that this is not possible for me, as I mentioned above, I have no Windows nor Mac computers here so I would need a generic USB Mass Storage solution that works in Linux.
    Thanks!

  • Powerbook G4 Mass Storage error

    I have a 15inch Powerbook G4 1.67Ghz with 512 mb of ram. I'm not totally sure of the exact OS I'm running, I can't get in to check.
    The other day I left it sitting on a pillow on a bed. It sat there most of the day, and wouldn't start up that evening. I found out the bed had a magnetic mattress pad on it. Suck. When I try and start up, I hear the startup sound, and I see the apple logo for a bit, then it goes to a black screen where I have the ability to type text. Thats it.
    It will go into target disk mode, but I'm never able to open the drive on another computer.
    I ran the Apple Hardware test, and it said I have an error in the Mass Storage.
    Error Code - 2STF/8/3:ATA-100ata-6-Master
    Anyone know what this means? Can I do anythin to get this back up and running? Is there anyway I can get my files off of it?
    Thanks for the help
    Aaron

    Sounds like a bad hard drive. I'd be really surprised if a mattress pad could have done the damage. More likely heat (if it was running on the pillow), or a coincidence.
    Can you try booting from the original OSX DVD? Since you ran the Hardware Test, I bet you can. Run Drive Utility and see if it can repair the HD. There are stronger 3rd party drive utilities that may help recover files if it gets to that, but I'm not an expert on them.

  • Time Capsule vs. Other Mass Storage Device

    I am a Mac newby seeking advice.  I recently purchased the MBA below to replace my personal PC.  My previous setup was a desktop with plenty of storage to handle my needs (including iTunes) and I backed up data directly to an external hard drive (I know pretty basic).
    After purchasing the MBA, I realized I do not have enough internal hard drive space to store all of my music and my current external drive is too small for all the media and backup of the MBA.  Also, the point of the MBA is to be mobile. Also, I would like my Sonos music system (with an application similar to iTunes) to be able to access the music library.  Lastly, I have far to many songs purchase outside of iTunes to use iTunes Match.  Therefore, I started seeking wireless alternatives to store my music and backup my MBA.  Although an NAS would probably be ideal, I have found out through trial and error that the basic systems do not work with a MAC and the only ones with a prayer are the more expensive ones (i.e. Synology and QNAPS).  Therefore, I have decided to pursue a more simplified approach.
    My Internet and TV provider is CenturyLink.  Their router is very basic with only 802.11g speed and without any USB ports.  The following configuration has been suggested to my by some more experienced Apple users to provide wireless data access and backup.
    Requesting CenturyLink provide me with a basic modem.
    Purchasing an Airport Extreme (or similar wireless n router with a USB port).
    Connecting the Airport Extreme (or other wireless router) to the basic modem.
    Purchasing a Time Capsule (or other mass storage device).
    Partitioning it using either the specific one for the Time Capsule (or Disk Utility for other mass storage devices) to provide one volume for my media and one for backup using Time Machine.
    Moving the media from my old external drive (which is catalogued with folders for each artist, subfolders for each album and the songs in the subfolders) by connecting the old mass storage device and Time Machine to my MBA and using Finder to do this (see the questions below regarding this).
    Moving/cataloging the media from the Time Capsule (or other mass storage device) by dragging it into the iTunes window.
    Connecting the Time Capsule (or other mass storage device) to the USB port of the Airport Extreme (or other wireless router).
    Setting up Time Machine to use the volume partitioned for backups.
    Possibly having to move cataloging files from my iTunes, Music folder to the external drive and pointing iTunes to the Time Capsule (or other mass storage device) through Preferences, Advanced to access the music.
    Overall, I am concerned with the total cost.  I just spent a lot of money, not only purchasing the MBA, but also the iPad 3 and upgrading my cell phone to the iPhone 5 (I skipped the 4).  It seems that by the time I purchase an Airport Extreme and a Time Capsule, I could also have just bought a NAS like the Synology 213 with 2 X 1TB drives, connect it to the existing wireless router via ethernet connections and have a more comprehensive solution.  Based upon these instructions and cost concerns (and bad experience), I have several questions related to this.
    Does this configuration and these instructions make sense, including those for moving and accessing my music files through iTunes (i.e. will it work)?
    Are both the Airport Extreme and Time Capsule necessary to make this work easily or can I purchase alternatives to either or each and if so, what is recommended?  If they are necessary, would you recommend doing this or buying one of the aforementioned NAS's to a Mac newby?
    Given the file structure for my music on the old external mass storage drive, can I simply move the folders over with the subfolders containing the musice files in them or do I have to literally enter into each subfolder, select all and move them subfolder by subfolder (i.e. album by album)?
    Am I missing something totally better and easier solution?
    I would be massively grateful to anyone who can provide some good answers, advice and guidance.  I am about to pull my hair out!!!!
    Thanks,
    WinoSkiBoy

    They both said about the same thing except the Apple Store business tech said to buy an Airport Extreme and just attach a partitioned external third party HDD to it.
    Except that is flakey for TM backup..
    http://pondini.org/TM/Airport.html
    And slow as the proverbial dog.. although I guess the dog is old.
    And totally inadequate as a media store or server.
    Apple's pricing is pretty cunning.. I really doubt you are going to find a cheaper unit to do both wireless and TM backups than the TC. And it is a perfectly good device to do that. It is good to have in the network. And Apple sure make their products work with other apple products.. so it does work better than other similar cost products.. although you miss a lot of features that Apple predecided for you.
    But I don't think anyone has the ideal solution to your problem. Apple believe in cloud. And if you have fibre internet that will work really well.. forks out your money and apple will store your stuff. But for the real world most of us do not have internet connection even a fraction of speed required. And it can be another decade before we will. We need a box that is half way between a TC and media PC, a file store and a NAS. Will Apple make one.. ?? I don't think so.. They believe in cloud..
    You can make the missing link one yourself. If you are so inclined.. A HP microserver running freeNAS can do TM backups and makes an excellent media store because it can do AFP. You can put a graphics card in it and plug it into your TV. You can use it with a airport extreme. But you will need a degree in Geek.. !! The synology is a preconfigured form of that.. No Geekdom required. Synology seems to have the upper hand.. this week.
    Let me make a suggestion.. Figure out if you are going to jump into the Apple way of doing stuff.. which is basically itunes on computer as a server.. and the whole network.. working as part of this.. so any media is pushed from a store in itunes.. whether local or internet..  if you want to do it that way.. getting something other than the air to run itunes is well worth it. That is what a NAS cannot do.. it cannot be a media player.
    Or you do hybrid.. ie you don't use put all your media into itunes, you use a bit of this and bit of something else.. As long as that can play files.. stored on NAS or even on the TC without the itunes requirement.. It won't be as pretty. But it isn't hard to get working.. as long as you accept this isn't going to be the perfect Apple solution.

  • Nokia C5-03 and Mac OSX Lion - Problems copying files to phone in Mass Storage mode

    Whenever I try to load more than one file from my iMac (early 2008, OSX Lion 10.7.2) to my new Nokia C5-03 in Mass Storage mode —since the files are MP3s and Multimedia Transfer doesn’t seem to work at all, I keep on getting asked which transfer mode I want to activate for several times, I always choose Mass Storage, and then the first file starts copying, but when it ends with the first one I have to wait for ±30s only to get asked the same again and again until the second file starts copying, and so on.
    It’s driving me crazy, I’ve tried setting in the USB connectivity options not to ask me for the mode when I connect the phone, but it doesn’t work either. It still goes very slow and a lot of “USB Mass Storage transfer mode activated” messages appear.
    I’ve tested it with a friend’s C5-03 and it’s still the same, but when connecting them to a Windows computer everything goes great and fast. Has somebody had this problem before? Is there a solution to this? I don’t know if this is the correct board to post this, sorry if it’s not.
    Thanks in advance.
    PS: Sorry if there are any mistakes or my English sounds weird, i’m Spanish.

    Hi,
    Can you try the suggestions below?
    -Go to Add/Remove Programs in Control Panel (called Programs

    Select Nokia Ovi Suite in the list of applications and click
    Change/Remove.
    In the dialog that appears, choose Repair.
    - Click Nokia Connectivity Cable Driver and repair
    -Try creating the connection between your phone and computer
    totally from scratch. Start by disconnecting your phone. In
    Nokia Ovi Suite, select Tools > Options > My devices. Select
    your phone at the top of the window and click Remove this
    device.
    Then, select Tools > Add new device, and follow the
    instructions to reconnect the phone. 
    If this doesn't solve the problem,
    -Uninstall the following programs withAdd/Remove Programs in
    Control Panel (called Programs and Features in Microsoft
    Windows 7):
    Nokia Connectivity Cable Driver
    Nokia Ovi Suite
    PC Connectivity Solution
    Then, download and install the latest version of Nokia Ovi
    I hope this helps.

  • [Solved] Banshee crashes while scanning USB Mass Storage mounted SGS2

    I did use the trik on a custom kernel, i do have freeze (none tomoroy but two today but only on using firefox, so may be another probleme (sna))  but not on video (well i had run 15 video same time, and two where running 2 hours after without crash). May be you should try it (i think it work better).

  • Ipod 4th gen Win XP needs a mass storage driver but can't find one

    Hi Guys,
    Just got a new PC, Ipod Was fine on my old one. However under Win XP, Ipod update and Itunes all installed correctly, but XP keeps asking for a MAss Storage driver. Tried alsorts of things including reinstallation of all iPod Software, but still as soon as I plug in my iPod, XP detects new hardware and asks for driver. ITunes doesn't detect iPod, but will happily play songs in my Library.
    Help.
    Maybe I need an idriver or an iXP operating system
    Cheers
    Andy.

    Its a new PC, so the install was from the original XP CD, then installed iPod and iTunes Software. I assumed the drivers where in the iPod Disc and not from the XP disc. I'll try the XP Cd.
    Thanks
    Andy.

  • USB Ports - Mass Storage Devices - Unknown Device

    Model: Satellite A135-S2276
    OS: Vista
    I recently tried plugging in my media card reader that I've had for several years now and has worked many dozens of times.   Windows responded with an 'Unknown Device'  response.  I thought this was odd, so I changed and tried each USB port.  To no avail the device wasn't recognized.  I tried it in another computer and it worked fine. 
    I began to try two other mass storage devices that I know used to work, up until recently, on the laptop.  Both now are 'Unknown Devices'.   I now have a strong feeling that someting was wrong with windows vista.  So I search around and find methods to force the driver (inf) cache to reset which should reload any corrupted drivers.   Tried many methods, nothing worked, same results.  I saw that Vista Service Pack 2 just came out, I installed that hoping that it would fix.  Nope.  
    I gave up on it being a software issue after I did a fresh reinstall of the OS and with the base OS with no other software installed same results. 
    Is there a way to diagnose if the USB is malfunctioning from a hardware standpoint?  Is it possible the USB, even thought windows recognizes it, is dead on the motherobard?  If so, how do I get this fixed?  Motherboard replacement?
    Help!!

    It sounds like it is working enough that it can recognize that soemthign is plugged into it.
    You say you did a fresh install of Windows.  Did you use the recovery disk or a retail Windows copy.  If oyu didn't use the recovery disk then maybe you are missing a driver.  Best woudl be to use the recovery disk.  If a USB mouse doesn't work after that then the hardware has an issue.  Assuming the BIOS is OK.

  • USB Mass Storage Device won't Eject/Unmount

    My brother bought a Sanyo ICR-B180NX digital voice recorder last year to use with his iBook. It was working very well up until about August of 2005. At that point, the recorder would mount on the desktop, and he could get all the files off (it records direct to MP3 format rather than WMV, so he can edit his files very easily), but when it came time to eject it, the device icon would disappear and then immediately re-appear on the desktop. The display on the voice recorder remained static at the "Connect" screen.
    I believe this happened in conjunction with some sort of OS update, as it was a "sudden" thing. We can't quite recall what happened between the times it worked and the time it stopped working.
    I have tried the device on a PC, and it works the way it should, so I don't believe there's anything wrong with it.
    Now, I know the system requirements on the website say that you must have Windows, but a statement from a support company (we returned it to the place where we got it, and they sent it out for repairs, and it came back with a letter) states that the device does act as a generic Mass Storage device, and thus may work with most systems.
    All my other USB storage devices (ie. SanDisk 12-in-1 card reader, SanDisk Cruzer Titanium 2GB, iPod Photo), and FireWire devices (ie. WiebeTech TrayDock Extreme) work fine and unmount fine.
    Does anyone know of any changes to the way Mass Storage devices are ejected in the current iteration of the OS? I haven't had a chance to test the device under an older OS, but will soon.
    Alternately, if anyone has any suggestions regarding replacements (not really looking forward to that, given this recorder cost almost $300CAD), let me know. We need a device that can plug in via USB and transfer files to his iBook which he can edit together (he's a newspaper reporter in training, and needs to edit the interviews to take out such things like dead air, etc).
    Thanks!

    Hi
    +USB mass storage device. An error occurred during the installation of the device the data is invalid+
    This typical error message appears if the installation of external USB devices failed.
    Why? This is not easy to say
    What you could do firstly is to clean your registry using the freeware software called CCleaner (Google for that).
    Install it and clean your OS and the registry entries.
    After cleaning access the device manager and remove all USB root hubs and all USB Host controllers from the device list and reboot the notebook.
    New reboot should cause a new installation of USB drivers.
    Finally try to connect and try to install your external USB devices again.

  • Help! mass storage error! please help

    i was getting frequent crashes in FCP with a Xserve RAID hooked up via fiber channel card for media storage. i'd get the spinning beach ball and would have to do a manual shut down, approx every 20 minutes.
    i did a complete erase and install of both system software and final cut pro software. still had problems.
    i did the apple hardware test and got the following error code - MASS STORAGE: 2 STF/2/3: SLOT-3, Channel: 1, ID:0, LUN:
    i got this error code ONLY when the RAID was hooked up, otherwise everything passed the test. the RAID mounts fine and in the RAID admin tools, everything gets a green light.
    since i am under a deadline and don't have a lot of time to troubleshoot, i rented another G5, bought a new fiber channel card with new cables, and hooked it up to the RAID.
    i am still getting the same error. again, the RAID array appears on the desktop, and the RAID admin tools finds everything ok - the fiber channel link ups, etc., check out ok.
    i really need to sort this out ASAP!! if anyone has any suggestions for me, i'd be most grateful - thank you

    Hey Kappy,
    I haven't seen that specific error before (prob since I hardly ever do apple hardware tests), but the spinning beach ball and the restarting does sound very familiar.
    If you've been getting this on both machines, my first guess is going to be a failing drive, since that can easily cause beachballs and hangs. Usually errors come up in RAID Admin, but I've personally had at least 5 times where a drive spazzes and there's no error at all to warn you (and of course applecare wont replace a drive or do anything about it til it happens, and you're screwed with performance until then) Possible things to do to troubleshoot:
    1) Play a video clip in FCP and loop it. Meanwhile, check the raid's blue LED activity lights and see if any of them are out of sync (not blinking in tandem with the rest) If so, chances are that's your problem drive. If the machine starts to spazz, from what i've seen, if its a drive problem, that one drive's LED will stay solid while the others blink seldomely, which means that drive is working overtime to keep up, but can't.
    2) Run drive conditioning from RAID Admin (I believe its only available under version 1.5). This will run for a while and is a great way to force the array to reveal any errors or failures in any of the drives. If you have a problem drive, this will be the best way to force it to turn yellow or red.
    For time constraints/deadlines, once you find out what the problem drive is and if the blue light is acting very erradically, drive conditioning will usually trigger the yellow or red light immidately (to where you can call apple and get it replaced under applecare). If you cant wait that long, pull the drive while its still green, and the raid will run in a degraded state (but your performance will be about back to normal). Just make sure and realize that you're not protected in Raid 5 anymore at that point. Even though, this has saved me in deadlines when I had a busted drive and couldn't play back a single stream of DV.
    As a seperate comment, going out on a limb and speculating (So dont hold me to it), if it was a drive issue, judging by your error, I would guess it's drive 3.
    NOTE: Always have a backup

  • Can't enable USB Mass Storage

    I am trying to use recovery software (Recuva) to replace deleted photos. When connecting to my laptop, I can only choose Media Device (MTP) or Camera (PTP). Recuva cannot find my phone without USB Mass Storage enabled but that option seems to no longer exist? What can I do to enable this?

    You need to enable USB debugging on phone, so the computer can see it as a storage device.
    Go into Settings, then scroll down to the bottom and click on About Phone.
    Scroll down to the bottom to where it says “Build Number”.
    Tap on “Build number” 7 times. After the third tap, Android will start counting down on how many taps are left before you can access the developer options, with a playful “You are now [insert number of remaining taps] steps away from being a developer”.
    After the 7th tap, you’ll get a “You are now a developer!” message.
    Now, go back to the main settings screen, and voila, the “Developer options” menu will be visible at the bottom, just above “About phone”!
