WD My Passport problem
Can anyone tell me what is going on here and maybe suggest a cure.
Long explanation follows! I have for the last 6 months used a 500GB WD My Passport drive with all my music on it 212GB, 3,479Folders, 41,546Files in my car with no problems, I recently took it out to add new music, but when I put it back in the car I got the message 'No music or picture files' So I reformatted the drive ExFAT, Folders and Files are named thus: folders A, B, C, etc. with folder with Artist name within and Album names within that and MP3s within that. I added a few folders (A & XYZ)put it in the car and all the music was seen and could be played, so took it back inside added C, D, & E but then got the message 'No music or picture files' again. Tried all that again with the same results, then deleted those extra folders, tried it again and it was now seen, there seems to be some kind of limit where there was not previously. How can I have all my music in the car with me again? |

It sounds like the car is adding files as "markers" to the file system. CHKDSK on the Windows end is removing something it doesn't like, then the car notices when the drive comes back. If your car system has a "quirk", Google should be full of the details. Paul |

Yes, they're portable but that means use one place, move to another place, and use there, but not during transport. Your high-school physics teacher didn't explain how grypscopes work? They never had you hold the axle on a bicycle wheel, spin it up, and had you move the bicycle wheel's axle? See https://www.youtube.com/results?sear...um+gyrosc ope. Didn't they teach you about momentum? And you don't the heads in a hard disk are supposed to fly but a few nanometers above the surface of the platters (fly height) which is far less than the size of a dust particle or even your fingerprint? When spinning (or even during spin up and spin down), the hard disk should be stationery. Some will survive a couple G's in force but not the jolting from driving your car over pot holes and gyroscopic effect will put extra wear on its bearing during turning of the car. Physical trauma kills hard disks. Even laptop users know their HDDs shouldn't be spinning when moving the laptop. Shutting the lid powers down the HDD so it is NOT spinning during transport. It's not only the jarring and gyroscopics while driving but heat also kills them. Do you keep the HDD in your pocket upon entering your vehicle, start the vehicle and put on the A/C (in summer) or heat (in winter) until the inside temp of the car is within the "operating temperating range" of the portable HDD before you plug it into power (USB port supplied or external power source)? Do you leave the portable HDD in your car when you leave your car? Do you leave it where the sun can get at it or leave your windows rolled up in summer? How are you going to keep it warm and within operating temperature range upon returning to your car that's been sitting out in the winter for hours with the portable HDD inside? Your car gets cold. Your car gets hot. HDDs have an operating temperature range but that means letting the HDD warm up or cool down to get in that temperature range BEFORE powering it up. Jobbers building car PCs are vexed with high failure rates of HDDs. Also, the WD My Passport drives are NOT ruggedized drives. I couldn't even find a G-force rating for them. Some "ruggedized" drives claim mil-spec drop ratings but that's just for one drop, not the constant jolting in a car driving over the road. Velco or otherwise rigidly affix your smartphone to your car's dash (so the phone is vertical) and get a g-force app, preferrably with a time graph to keep your eyes OFF the phone while you are driving, to show you how many G's are those potholes, speedbumps, or whatever you encounter while driving. From what I've seen of the specs for ruggedized hard disk, they are to survive abuse when NOT in use. https://www.wdc.com/content/dam/wdc/...779-705155.pdf Page 4: - Do not jolt the drive. - Do not move the drive during activity. (*) (*) Means when the drive is active (powered and spinning). You don't use HDDs when your car is moving. When the car is moving, you only transport an inactive HDD. Nor do you store HDDs in your car. Run "chkdsk drive /r" on that portable HDD to mask out any bad sectors that have cropped up due to your abuse of the portable HDD. Did you check the specs on your "car player" to determine what file systems (FAT, NTFS, exFAT, other) that it supports? Within each format, the player may still have its own limit on the size of a file, the size of a partition, how many partitions are supported, and how many files can be within a folder. The firmware in hardware players is not equivalent to what a general-purpose OS (Windows, Linux) can handle. Copy the files off your USB hard disk onto a USB flash drive and use the USB flash drive in your car. Even those, however, have an operating temperature range but they are not susceptible to gyroscopic bearing wear or subject to momentum (beyond the physical construction of the flash drive but by then your car and you aren't in such good shape, either). |

Probably because the car system firmware has a limit on the number of folders and/or files it can handle and you have now exceeded the limit. With 41,000 tunes I doubt you will miss a few if you try deleting them. |

With 41,000 tunes I doubt you will miss a few if you try deleting them. I had already considered a limit but I am putting on nowhere near what it was previously able to handle, as I said in my original post, it was able to see my whole collection, I have now tried another drive and the results are the same so I suspect a fault in the car system (it is a late 2015 Mercedes c63) Of course I've tried googling, but putting the words 'hard drive' into a search are not productive as it throws up 1,000s of unrelated posts. thanks for your suggestions but I've about given up and am using 2 memory stick instead, not all my music but enough. |
