i have two hard disk drives connected and ive had this problem in the past. some days its fine some days its this same issue for literal years. but it seems when i copy large amounts of files say 23,000 files and 167 sub folders with a file size of 1.4 TB i have issues copying them. ive tried dolphin, i tried dolphin as a flatpack, i tried fsync, i tried the cp command. it seems like no matter what i do it seems to copy files fine then itll stall for like 30 seconds then copy a bit and stall for 1 minute or so then copy and stall for 5 minutes or so and so on and so on. this continues until the copying process is basically not doing anything even if i leave my computer on for days at a time. it seems that i can copy anything less than 50gb at a time with little to no problems or stalls. and its like this no matter what computer i use or what drives i have connected. maybe it has something to do with kioworker idk anymore.
How are the drives connected to the system?
During the copy, what does cat /proc/loadavg show - both before the issue starts, and when you start seeing the issue?
If you’re using command-line tools, kioworker is unlikely to be involved at all.
It seems likely to me that you’re overwhelming the bus with the volume of data, and the drive eventually is running out of cache and is telling the system to wait while it flushes its cache.
This can be more pronounced if the drive is connected via USB (particularly USB 1.0 or 2.0).
I might also be inclined to look at the dmesg output during the copy to see if there’s a hardware error being reported. That can seriously slow down file copy operations.
so the load average during the start is 4.28 1.92 1.27 1/1299 43818.
here are some info from dmesg

i did disconnect one of my drives a few times when it wouldn’t disconnect or just became unresponsive.
my load average when its not doing anything or stalling or hanging is.
20.33 19.44 13.83 1/1241 44505
they should all be using usb 3 at least and one drive is connected via usb 3 cable the other is i think usb 3.2 usb C to A cable with the C part being output from the enclosure.
NOTE: i did noticed when its “stalled” or “hanging” i do still have cpu cores currently at 100% load from core to core but ill report back in the mourning. thanks
Well, the I/O errors on /dev/sdc are likely the cause - it seems you’ve got a hardware issue going on. That’s going to kill performance. The USB disconnect is probably the root cause, but if that’s happening because of a hardware failure in the drive, then it’s a constant disconnect/reconnect/IO failure loop.
Those loadavg values don’t look great either, when not doing anything, the values should be low, not over 20 (that’s the 1 minute average). The values at the start are not bad for a lightly-used system.
I’d probably look at iotop as well, iowait% is probably pretty high when things are slowed down.
smartctl might tell you more about the drive, depending on how well it supports SMART diagnostics.
But this looks to me like a hardware failure in progress.
well it finished copying this time maybe im just used to having new and fast hardware like nvme drives. i mean it took maybe 6 hours to copy about 1TB to a 5400 rpm usb hdd. also note i think it was my wire i used a new one and it seemed to copy fine just super slow and what seems like stalling then starting until the operation finished. also i checked smart all these drives are basically new and it reported that they are in excellent health.
A bad cable could certainly cause this as well - glad to hear it’s sorted.
