Reliability of USB Flash isks

By cto95 ·
My experience with flash disks have not been very pleasant. Not especially when I relied on it as a data backup medium, when there was a need to format the hard disk of one company I was maintaining there network infrastructure.

After backing up the data, read it back, and confirmed, that the data was actually written to the flash disk. And to my greatest shock! After re-installing the operating system files and applications, I could not find the data I just wrote to the flash disk. It has dissappeared.

This incident has happened to me twice now!

Can anyone find any reason why, or ist just that the USB flash disk technology is in its infancy and not yet a reliable means of carrying or moving data.

Regards ALL

USB Flash disks have been completely reliable for me

USB Flash disks have been completely reliable for me. Flash is very reliable memory and used everywhere.


Are you sure the data written to the USB flash disk actually made it to the disk itself? Was write caching disabled or enabled? If write caching was enabled, the data could have still been in the cache when you removed the USB flash disk.

How to check (Windows XP):

1. Right click on the USB flash disk icon and choose "Properties".

2. Properties window, "Hardware" tab.

3. Select the USB flash disk from the list of devices by clicking on it. Click the "Properties" button.

4. Properties window #2, "Policies" tab.

5. In "Write caching and Safe Removal", make sure "Optimize for quick removal" is selected (this disables write caching).
