Reliability of thumb drives

sdfoo 15 10 July 3, 2016 at 08:14 PM
I bought three Emtec 8GB thumb drives from the Fry's Friday sale. I copied a couple large zip files over to another system using one of these drives and could not unzip the files.

I found a test program and 2 of the drives were faulty. Is this typical of thumb drives or is this brand just really bad? Unless I was really unlucky, this is an unacceptable failure rate. And the worst part about it is that there is no error during the copy, so you won't even know that the file is bad until it is read.

Is there any way to salvage these drives? The cost of gas would be more than I would get back.

Its not typical. When buying media to store data, always buy known good brands.

it would cost more to try and get back the data than to go back to the store and get replacements. just buy from reputable brands next time.

Only the big name brands will have a decent life span. The others are crap, and sometimes don't even have the full adverised space. I've seen reviews where people buy a 32 GB chinese brand, reformat it, and it only has 8 GB.

This isn't even getting into lifespan issues. It is broken out of the box. I bought them from the sale this Friday and loaded files the next day and they are corrupted on the first usage. These are sold at BestBuy too and made in Taiwan, so I thought it was not quite as bad as buying the non-name stuff off of ebay.

some of the real crappy ones come out of the box already broken.

both bad luck and reliability.

8GB only use one tiny flash chip, even brand names can have bad chunk out of box, and maybe it doesn't have any hidden extra space to replace the bad parts like other faster drives.

you can try to hide the bad parts by using lots small files, then verify the hash (try GetMD5Checker.com), copy all the bad ones to a folder, then delete the good files, maybe it can be use this way, if the controller ignores the bad parts like an HDD.

you need to use a command to create pre-allocated files to fill it up if copy paste has error. so it won't try to write a bad sector.

What 'test program' did you run to find the faulty drives? Also where the large zip files over 4GB? If so, you may need to format the flash drive to NTFS. See this LINK [sandisk.com] for more info:

"Why can't I transfer a 4GB or larger file to my USB flash drive or memory card?
This is due to FAT32 limitation. Files larger than 4GB can NOT be stored on a FAT32 volume. Formatting the flash drive as exFAT or NTFS will resolve this issue."

The zip files were 500MB and 600MB, so well under 4GB. I used ChkFlsh and h2testw to test. ChkFlsh has options to bypass the file system and test as a logical drive and physical drive.

Just picked up a few SanDisk drives from the Kmart sale mentioned in Hot Deals, but haven't tested them yet.

Have you tried calling Fry's? A few minutes on the phone could net you a voucher for your next visit whenever that may be.

It can't hurt to ask.

You may want to check the forums at HDDguru.com, but some thumb drives come with faulty firmware in their controller chips because apparently companies can save money by purchasing chips without firmware in them and putting in their own cheaper firmware. Another thing to consider is that some thumb drives claim faster speeds than the ratings of the flash chips they use, and I saw this even on a major brand drive.
