Why the TV does not read the hard drive

In the modern world, together with the improvement of the quality of photos, audio and video, the amount of external storage memory occupied by this data increases proportionally. Unlike a flash card, an external hard disk has a huge amount of memory and speed of information transfer, therefore recently it has become so popular among users of technical equipment. But what if your TV does not see connected external hard drive? First, you need to identify the cause of the fault:

lack of power to the hard disk;
outdated software of your device;
incompatibility of hard disk and tv file systems.

Consider each problem separately.

Lack of power

One of the common problems for which the device does not see the hard disk, may be a lack of power for the hard disk. If you are the owner outdated tv modelWinchester will not be able to get the energy it needs through a USB connection. Winchesters can be classified into 3 types according to their generation and the amount of energy they consume:

USB 1 - 500mA, 5V;
USB 2 - 500-1000 mA, 5V;
USB 3 - 1500-2000 mA, 5V.

One of the most logical ways to solve a problem is to connect a hard disk by Y- splitter. Powering the hard drive in this way depends on the number of USB connectors on your device:

one connector;
two or more connectors.

Y-splitter

When the device has several USB connectors, then problems should not arise. Connect the hard drive directly to the two connectors on the TV through a splitter. In this case, the voltage is enough for the full operation of the disk. If the TV is equipped with only one USB-input, you need to connect the Y-splitter in such a way as to connect the hard drive with your TV, and at the same time use the power supply of a third-party device (phone, tablet, etc.). The hard drive will be powered by the power supply, and the missing energy will be taken from your device.

Tip! To verify that the cause of the malfunction really lies in the lack of power, alternately connect flash drives in the corresponding connectors on the case. If files on flash cards are read, then the USB port of the TV is in working condition.

Outdated software

Another common reason why a TV does not see removable media is outdated software. The recognition function of such a large volume of media is inherent, as a rule, only the latest TVs. If the TV has enough power to work with external drives, produce firmware upgrade. For this:

visit the official website of the manufacturer;
go to the "support" section;
select “software update”;
enter the model of your device and download the corresponding file;
perform the update.

Flashing software

If the problem persists, your TV model may not support the hard disk due to its high volume. For example, if the device is designed for the maximum size of removable media in 1TB, it will not be able to synchronize files with the hard drive in 2TB.

File System Incompatibility

Many TV models do not read hard drives if they do not correspond to the FAT32 file system.The fact is that most of the equipment is designed to work with flash cards, the volume of which, as a rule, does not exceed 64 GB. With a relatively small cluster size, FAT32 makes more efficient use of limited flash memory. This is the reason why most flash drives use this file system.

Unlike Fat32, NTFS The system allows faster and safer data transfer from media to a computer or other reading device. This file system supports working with large amounts of information and has no restrictions on the size of the copied files.

Important: before buying a TV pay attention to the instruction manual. In it you can find a lot of useful information about the compatibility of drive file systems with the device. There are cases when the instructions indicate models of hard drives with which the TV will not work under any circumstances.

The latest TV models from companies like lg or samsungable to see the disk with the file system NTFS. In addition to the usual recording of information, such devices are capable of reproducing coded data.

File system check

If the device has stopped seeing the drive

In this case, the phrase "stopped seeing" implies that before your device was free to synchronize with the hard drive, but after a while it stopped doing it. There are two reasons why a similar fault occurs:

the presence of viruses on a removable disk;
failure of the drive itself.

Modern viruses can not only damage individual files on the hard drive, but also completely destroy the file system. Since televisions are a rather "capricious" technique, a virus attack can paralyze it. The only advice to avoid visiting a repair shop is to check all uploaded files for the presence of virus programs before transferring them to other devices.

To distinguish the failure of the hard drive from TV malfunction, it is necessary to carry out a test of work with another removable disk. Connect it to your TV in the same USB connector. If the "check" hard drive is perfectly synchronized with the TV - it means yours have become unusable. The same check can be made even if the TV does not see the flash drive.

P.S. The problem of connecting an external HDD (drive, hard drive, hard drive) to the TV - solved !!
I have to correct my previous statement about replacing the MBR with GPT or vice versa - the problem is deeper.
The GPT tabular standard is required to read TV drives over 2.2 TVs (the limit for the MBR), while the computer reads without restrictions. And increases the life of the HDD.
Working with me, with a PANASONIC TX-49DXR600 TV, the Seagate STEL8000200 HDD (8 TB) has the following parameters: GPT, NTFS, cluster of 8 sectors of 512 bytes, has a 128 MB MSR partition (logical disk) .
The MSR section on the drive does not matter, and is used, most likely, for alignment (offset to 1024 kV) and as a buffer memory for the controller. It is created by the application Diskpart, which is in Windows.
The parameters mean that this drive has the old layout of the magnetic track - 512 bytes (sector size is not physically changeable), and most modern drives (starting from 2010) are made in the new Advanced Format - the new sector marking format, 4096 bytes (4KV ).
Thus, it can be stated that the problem of the majority of unreadable drives in the sector size is 512 or 4096 bytes.
Unfortunately, this technical parameter is not specified by the manufacturers.You can define it like this: on the computer, hover over your external HDD, right-click and select “format” - the minimum size is specified in the formatting options when selecting the cluster size, this will be the sector size (512 or 4096 bytes).
Therefore, ask the seller to specify the size of the HDD sector.
In my case, you can use disks with sectors of 4096 bytes (I have two) in the format with the FAT32 file system, which limits the file size to 4 GB. For films of low resolution - come down. To reduce the size of the video file, I recommend the free Avidemux 2.6 program, which allows you to reduce the size and quality of the “stream” and divide the file into parts, besides copy the video from one container to another (for example, from .avi to .mkv) without loss of quality and convert one video or audio codec to another, since not all containers and codecs are read by televisions (software problem).
The problem that the TV reads the NTFS file system with a 512-byte sector markup, and does not read NTFS from 4096 bytes, is the inadequacy of the USB controller driver installed in the TV software.
If both markup are not readable - format it into the FAT32 file system, it is supported by flash drives.Sometimes the driver does not support GPT, then replace with the MBR.
To format into the FAT32 file system, you need to use the program Paragon Hard Disk Manager or the like. Using Windows for FAT32 has limitations.
Demand from the manufacturer of the TV driver updates (for USB-controller) with support for HDD format NTFS with sector marking 512 and 4096 bytes.

The problem of connecting an external HDD (drive) to the TV is solved!
If your TV does not see the connected HDD, then this is a problem in the standard (style, layout) of the disk format, not to be confused with the file system (FAT, NTFS).
Basic standards: MBR (master boot record) and GPT (GUID Partition Table). GPT - new, replaced the old one - MBR.
In order to determine which standard your HDD has, you need to open: Control Panel / System and Security (or System and its maintenance) / Administration / Creating and formatting partitions on a hard disk. Next, “Computer Management” will start, or open a link with this name (depending on your OS, the Windows version).
In the list of disks that will open, select your external HDD and go to its properties (right mouse button). Further in the "Tom" section, opposite the "Section Styles" line, you will see with what standard your disk - MBR or GUID (GPT).
In order to change (convert) the standard disk from MBR to GPT and vice versa, you need to use the program Paragon Hard Disk Manager (Paragon HDM 2010 Pro) or similar, you can download on the network.
It is important to remember that to change (convert) means to format the disk, and therefore, the information on the disk will be lost. Therefore, before performing this action, copy the contents to another medium.
For example, my PANASONIC TX-49DXR600 TV (4K Ultra HD) did not read the external USB HDD Seagate STBV5000200 (5 TB), since He is in the standard MBR, and read the HDD Seagate STEL8000200 (8 TB), which is in the standard GPT.
Moreover, the specified HDD Seagate STEL8000200 HDD opens (works) on a computer with Windows Vista Home Premium, despite the “from Windows 7 and higher” label and connected to the TV, despite the “only computer” label, they make a fool of our brother.
When buying a TV, I turned to PANASONIC technical support - they could not explain the cause of the problem, due to their incompetence. They offered to use HDD size 1 TB, under which tests were conducted.
Half a year was tormented with a flash drive (32 GB), you cannot write a file larger than 5 GB to it, because FAT32 file system. I had to split the file with a special program into parts, the 10 GB video file was broken (reformatted) for two nights (about 14 hours). After the appearance of 4K video files, I decided - enough.
I had to conduct a study on my own.

Thank you! It didn't work out right away, I had to drive a screw, but everything went off with a bang. Solution: a combination of file system types, FAT or NTFS, plus MBR or GUID (GPT). But thanks anyway!!!
