|Several years ago I acquired several SanDisk USB 2.0 drives, 32GB and 64GB. I developed a batch file to backup selected files from my Windows desktop to the the USB drives. Works as expected.|
Now I need USB drives with greater memory. Tried some cheap 128GB drives from China, had problems. Recently tried more expensive but still cheap 128GB drives from a US seller, same problems.
Here are some observations re the problems experienced with the less expensive (read cheap) USB drives:
- Using my batch file, the first folder copied seems to copy OK, including subfolders and files. But the remaining folders copy the top folder to the USB drive, no subfolders, no files.
- Even when I drag and drop folders to the USB drive, often times many folders/files do not get copied.
- When a folder is copied successfully, the "size on disk" folder property is generally substantially larger on the USB drive than on the hard drive.
Are there parameters within Windows that I need to set so these USB drives can be used to successfully make backups? Or are these cheap USB drives to be avoided because they are not reliable? Or something else?
