| 1431728 | 2017-02-08 23:39:00 | I have several USB2 32GB Flash Drives and they all show the same transfer of data to Computer Hard Drive: namely that it is slow and the transfer rate changes. I tried to highlight all files/folders on a drive and Drag-Move to folder on C Drive Desktop...it starts I go away overnight because it shows time remaining as 8+ hours, return in morning and have many windows saying "a problem prevents transfer of this file' I click to Skip and ended up with a Flash drive showing nothiong in it. Reopened the drive in Computer and all files etc still there. All I can do is move/transfer 1 file/folder at a time. Now what I am seeing in the Moving Item window are file etc from-to and Time remaining, Items remaining and Speed. Here are examples of the details I am seeing as the file is moved..I give details for 2 transfers: at 10:56am today 1/ Time remaining: Calculating Items remaining: 1 (2.34GB) Speed:0 bytes/second at 11:02am 1/ Time remaining:8 minutes 30 seconds Items remaining: 1 (1.64GB) Speed:2.18MB/second at 11:05am 1/ Time remaining:14 minutes Items remaining: 1 (1.53GB) Speed:1.62MB/second at 11:14am 1/ Time remaining:18 minutes Items remaining: 1 (1.08GB) Speed:1.20MB/second at 11:23am 1/ Time remaining:about 35 minutes Items remaining: 1 (836MB) Speed:985KB/second then it finished after that another one showed as follows at 7:47am 1/ Time remaining:Calculating Items remaining: 2 (1.12GB) Speed:53MB/second 1/ Time remaining:8 minutes 30 seconds Items remaining: 1 (1.64GB) Speed:2.18MB/second at 7:48am 1/ Time remaining:About 45 seconds Items remaining: 1 (1.02GB) Speed:2.36MB/second at 7:49am 1/ Time remaining:8 minutes 30 seconds Items remaining: 2 (1.01GB) Speed:1.27MB/second at 7:51am 1/ Time remaining:23 minutes Items remaining: 2 (947MB) Speed:1.01MB/second at7:52am 1/ Time remaining:About 18 Minutes Items remaining: 2(944MB) Speed:850KB/second at 8:17am 1/ Time remaining:About 40 Minutes Items remaining: 2(288MB) Speed:523KB/second at 8:24am 1/ Time remaining:About 35 Minutes Items remaining: 2 (162MB) Speed:480KB/second at 8:26am 1/ Time remaining:About 20 Minutes Items remaining: 2 (42.6MB) Speed:506KB/second It finished after that. Sometimes that Speed will be anything from 100KB/S to 999KB/S What would you consider to be the problem causing these slow-erratic transfers from USB Flash drive to Computer HDD? Not too long ago I could have highlighted them all and transferred all to Com HDD in 5 mins. I have to go out for 5 hours now so will check back here when I return. Thanks in advance.

| 1431729 | 2017-02-09 00:18:00 | Have you tried other USB ports and tried the flash drive on other computers? Easy way to tell if it's the drive or the PC is to try it somewhere else. When you try to copy them all at once are you only doing a single transfer and not starting several different ones at the same time? Dragging everything at once is fine but dragging them a few at a time before the first one finishes will always be very slow. I'd need the exact wording of the error message to try and understand what's happening there, are you sure the destination drive has enough space and you are not copying duplicate files over top of existing ones? I've personally found all USB 2.0 drives to be pretty slow, the fairly average cheap ones seem to do around 12MB/s transfer rates and only a few decent ones do better. If you want fast go for a USB 3 drive even if you are only using USB 2. They are more future proof and tend to be faster even when limited by a USB 2 port (somewhere around 40-44MB/s in practice). I have one older USB 3 drive that was very expensive that manages 40-75 MB/s depending on the type of files and a newer cheaper one that does 30-50 MB/s. The cheap one would not be slowed down all that much by USB 2. |

| 1431730 | 2017-02-09 00:25:00 | are all those USB sticks the same brand ? KB/s or Kb/s Not so unusual for speed to drop a bit over time on large tranfers is the PC USB port USB2 or just USB1 (dont assume on older PC's) from or rear usb port ? Just tried a slow 8G USB2 stick on 2 PC's here (some USB2 sticks really are just much slower than others) 1st PC : 2MB/s , dropping to 1.5MB's 2nd older PC 2.5Mb/s ( thats bits not Bytes) .( USB1 port I think? ) try on another PC, you may have a hardware fault try another brand USB stick, from a reliable supplier. Plenty of faked 'brand name' USB sticks around . Some sticks are just slow . try disabling AV try rear USB port if using front port |

| 1431731 | 2017-02-09 04:08:00 | 1101 The USB sticks were of 2 brands and I purchased them from The Warehouse over a period of 2-3 months 2 year ago. I am not sure of Brand name now but looking on net at Warehouse offerings today one of the 2 brands would be Tech.Inc and they are showing them as 32GB USB3 for $19...they were $20 something when I bought the USB2's 2 year ago. The other brand I have is the Swivel type and I cannot see it listed in Warehouse now, but checking another Major store they have them but they are named Kogan and that is not the brand I have, just similar look. KB/s not Kb/s. PC USB port are USB2 Rear ports on Mobo. I don't have another computer running at the moment that I can try the sticks on but my neighbour has a decent laptop I can try them on and do a data transfer from stick to Desktop folder. Thanks |

| 1431732 | 2017-02-09 04:23:00 | One thing I found over the years, on Some USB drives, "Moving" takes longer than "Copying" the same file. Moving also runs a higher risk of Deletion, if something goes wrong when moving you can lose the lot, a copy wont. You just %$$(*)(%^&!@^&$* and try again. |

| 1431733 | 2017-02-09 04:27:00 | dugimodo yep I tried other USB ports...amd using the rear ports that are on the mobo. When I tried to move all the data on the USB stick to a desktop folder in one lot it was just that, highlight right mouse hold down and drag/drop in desktop folder and click the Move option....it would start and show 4 or 5 folders/files in the desktop folder, then it would simply freeze and do nothing. So I had to do the data move 1 folder of a file at a time. I tried to move 2x2.7mb.pngs from the stick to the desktop folder and that should have been done in a blink of an eye, nope, it showed one of the.png's in the folder and then took almost 5 minutes to complete getting the other one moved. This 'slow transfer' is a new happening....and a lot of these 32GB USB's I have the data on have not been used in the past 18-24 months...I put the data on them because I was low on HDD Space and when I purchased a new 4TB External HDD I simply forgot to transfer the data from the USB's to the new HDD. Now I want to use the USB's and am attempting to empty them to computer HDD. |

| 1431734 | 2017-02-09 04:29:00 | wainuitech yeah I considered doing a Copy/Paste or a Cut/Paste but haven't yet. I will try a Copy shortly when the final transfer on the current USB has completed and I try moving the data on the next stick. Thanks |

| 1431735 | 2017-02-09 06:51:00 | wainuitech, dugimodo and 1101 solved, thanks to wainuitech's suggestion: after the last file completed move to desktop folder I formatted the USB stick and sent the final 2.74GB file back to the stick, using the Copy option, it complated that task in 1 minute starting at a speed of 63.5MB/s and settling at 36.4MB/s. I then decided to Copy it back to a new folder on desktop and that completed in 1 minute at a settled speed of 28.8MB/s. I then connected another USB stick containing 29.2GB Data, created a new folder on desktop and then highlighted all files/folders on the stick and used the Copy option to put all into the new folder... it completed this in 15 minutes at a speed constant 28.6MB/s ...28.3MB/s. Very happy about that. Now just to check I will create a new desktop folder and try to do the Move all at once and the Move 1 file at a time and see if I get the same slow transfer rate. I won't bother letting it take an hour or 2 to move a file....I will stop it the first 30 seconds of seeing speed drop to what I was getting before. Thank you all Kioti |
