How to Repair Excel Document on a Flash Drive

Summary: Microsoft Excel files are stored on flash drives if they need to be transferred between systems or if they need to be backed up. But sometimes unforeseen issues can corrupt the Excel sheets stored on flash drives. When that happens, it can be an arduous task to repair Excel documents on a flash drive. Through this post let us try to understand the reasons why Excel sheets stored on flash drives can get corrupted and how users can resolve them easily.

In this digital age, we all work with computers, files, and documents. Flash drives or USBs are common ways of storing data in an external place. Be it for a meeting or for a party playlist, these devices come handy when one wants to transfer data or access the files stored elsewhere.

You may need to access your data from another location. That’s when a USB flash drive might come in handy. And, that’s exactly why Excel sheets too end up on flash drives; either that or for backup purposes. However, there are many instances where an Excel file stored in a USB gets corrupted when one tries to access the file. The error message you get while trying to open the Excel file would be a great clue for figuring out the exact reason behind corruption.

This blog will provide insights into what are the reasons for the corruption of a USB and how the users can repair Excel on flash drive that has been corrupted.

Reasons for USB inaccessibility

Sometimes flash drives or USBs can become unresponsive due to numerous reasons. There are two types of corruption – logical and physical. Physical corruptions occur due to broken stems and connectors, broken circuits, NAND gate, not recognised, RAW, need to format, not accessible, and dead drives (no power supply).

One of the main reasons behind such an error could be that the USB drive has been infected by some virus. This can affect any file – not only the ones which are there in the USB drive but also the ones which are there in the PC/Laptop where you connect the USB drive. It is recommended that you scan the USB drive with reliable antivirus software to detect viruses.

There can be various other reasons that may make your USB corrupt or unresponsive. But there are very slim chances that you will be able to recover a flash drive that has physical damage. However, you can try to run the check disk on the USB drive to fix the drive. We will be discussing this as you read on.
