What’s the Difference Between TF Card and microSD Card – T-Flash Card Recovery Software

TrashFlash, formerly known as T-Flash, was introduced by SanDisk Corporation in 2004 as the world’s smallest memory card, approximately the size of a fingernail. TransFlash (microSD) was specifically designed for being used in mobile phones. In 2005 TransFlash was adopted by the SD Card Association as the third form factor memory card in the Secure Digital family, after SD Memory Card and miniSD. After the adoption, TransFlash changed the name to microSD. The microSD has exactly the same dimensions and specifications as the TransFlash and therefore both memory cards are completely compatible with each other.

TransFlash memory card and microSD memory card are very much alike and can be used in place of other one but there is little dissimilarity. microSD cards can support SDIO mode which means they can perform non-memory jobs such as GPS, Bluetooth and Near Field Communication. But a TransFlash cannot do such non-memory jobs. There is also a switch on security segment in SD card whereas TransFlash has no such feature in it. The volume of TF card is 15 mm x 11 mm x 1mm and the volume of microSD card is 24 mm x 32mm x 2.1 mm. Apart from this few differences TransFlash and microSD cards have no other major difference. As of from 2014 till now TransFlash and microSD memory cards are considered to be the same as later TransFlash was named as a microSD card by SanDisk Corporation.

Apart from this few differences TransFlash and microSD cards have no other major difference. As of from 2014 till now TransFlash and microSD memory cards are considered to be the same as later TransFlash was named as a microSD card by SanDisk Corporation. TF card in 2004 was accepted as the latest generation of memory cards.

Recover Files from SD Card Partition Problems

Nowadays, you can see SD cards being widely used on many devices like smartphones and cameras to extend storage capacity. Unlike built-in storage, SD cards can be removed and accessed on other devices. The frequent plug in and out makes SD cards prone to damage and potential data loss. 

You might have received error messages like "The file or directory is corrupted or unreadable" or "Disk in drive X:\ is not formatted. Do you want to format it now?"  before. However, to be sure the problem is actually caused by partition corruption, you need to first check the SD card for any potential physical failures.

1.First, we need to make sure that the SD card is actually at fault. If you've inserted an SD card into your laptop or PC's built-in slot and nothing happens, try using a USB card reader and try different ports. Connect your SD card to another device if you have access to one.

2. Check if your card is shown up in Disk Manager. You can open Disk Management by typing diskmgmt.msc into the Run dialog and press Enter.If it is there, see if Windows has assigned any drive letter to it, manually assign a letter to it if not. Also, check if there are any icons (yellow question mark) under Device Manager. Renew device driver or re-enable device to try to solve the problem.

3. Check if metal wires in the card slot are corrupted or twisted. Many SD cards support hot plug, which means you can insert or remove the card while the device is still running. But frequent plug and unplug can result in twisted or rusty metal wires in the card slot. Use a needle to straighten the wires if they are bend or remove the rust if they are rusty.

4. Check if the SD card is clean. Dirt or oil stain can cause the SD cards undetectable by computers. Check whether there are dark spots around the metal area of the card. Clean with alcohol or water. Then, dry it out before put it back to the phone.

After you ruled out all the other physical damages, we can begin to recover files with H Data Recovery Software.

How to recover files with H Data Software
