I setup a USB external drive on my R7800 using the simple guide from here: https://wiki.dd-wrt.com/wiki/index.php/USB_storage#Updated_Instructions

But suddenly I cannot access it from a network device. I unplugged it from the router and connected it to USB on my Mac to confirm it's working fine.

I restarted the router, turned off USB services, confirmed under NAS services that the drive is detected still. On my Mac I can see dd-wrt in my network but I immediately get "Connection failed"

Here is what I see under the USB services tab:

Diskspace /tmp/mnt/sda1

I also saw that in Drive Manager under the NAS tab,
it lists /dev/sda as Filesystem:Partition. But the above output lists it as exFAT filesystem. Should I change it in Drive Manager to exFAT? Would that potentially cause a format?

I turned off automatic drive mounting. Hit apply. Then turned it back on and hit apply again.

Now I have 4 drives listed when I only have one partition. I'm using exFAT, Kong 39345M.

Further update: I turned off Automount & NAS and rebooted. It removed all the duplicate drive entries but still unaccessible.

I'm trying to manual mount the drive using UUID but 'blkid' is only returning AE24-0E15 as the UUID. I don't know if this is the correct UUID but it's alll I get. Separately, I can navigate to /tmp/mnt/sda1 and see the contents of the drive without issue but cannot connect via Finder.

Some info from dmesg below:

So I upgraded to R43028 4/29/20. Reset to default and setup the router again. Same issue persists. Unsupported filesystem.

I'm at a complete loss, I checked the modules and exfat is there. It was working as a simple network share until it suddenly stopped.

Edit: If I decide to format the drive, what is the best format for a mixed environment of Mac/Windows/iOS?

[Alozaros]

hmmmm if you intend to move the drive (not recommended)
than i don't know...not sure if exfat is stable...
otherwise ext3 or ext 4 for hdd or ext2 for flash thumb drives...as its a linux system anyway..

[fathornet]

I have no intention of moving the drive. It’ll stay on the router. I just can’t find anything other than exFAT that can support what I need.

[Alozaros]

you can install ext2/3/4 filesystem support on your OS instead...

[fathornet]

So when searching for a possible file format solution NTFS/ext2,3,4/etc I found a thread about BS builds no longer working with bonjour and other broadcasting protocols for the hard drive.

So I was able to connect via IP address and lo and behold the drive mounted. I could read/write without a problem. Unsupported file system is still listed under the USB services but it's working.

Fingers crossed it remains up.

[fathornet]

I spoke too soon, the drive is discoverable and can mount but nearly all file transfer is failing with Finder errors. Error -36 when trying to copy to the drive and error 8084 when trying to copy from the drive. Oddly enough I can view the contents of the drive without a problem. Only the smallest of files under 10MB can be copied to the drive.

To be certain I unplugged the drive from the router and plugged in directly to my Mac and thankfully none of those errors occur. So the hard drive file system is intact.

Now to find out why these errors are happening

[fathornet]

After even more troubleshooting it appears that having NAS will not work.

I partitioned the drive as ext4 on my Mac using 3rd party software (Paragon). I labeled it JFFS to have it auto mount which it did. And for a day both my Macs could read/write natively. It didn't make any sense to me how they could do so. But then suddenly it marked all files being transferred to the drive as unreadable/writeable.

Frustrated, I partitioned it again as exFAT, labeled as JFFS, and had zero luck yet again. Wouldnt even mount to JFFS. I don't know how anyone with a Mac has a NAS setup. If you do I'm all ears.

[Per Yngve Berg]

It has been a lot of problems with NAS on a lot of later builds this spring.

Try 43306 or later.

[blackraiin]

So I have a Mac also and NOTHING works for me. I tried the newer builds and ended up reverting to the last build of 2019. That is the last working build in my opinion.

I have 2 external HDD formatted using NTFS. One of the HDD is almost at 100% capacity so I am not even thinking about reformatting that and the second one is at least a little over 100+GB capacity of 8TB HDD.

So what best suites me is to use the last build of 2019. It works and not upgrading the fw until or if this current issue is fixed regarding Samba.

[fathornet]

Thanks for the input. I thought I was alone in this regard. I'm running 43028 4/29/20. I'll decide soon whether revert to last build of 2019 or the newest BS build.

If rolling back to an older version are there different steps than upgrading to a newer firmware?

[blackraiin]

[fathornet]

I upgraded to 43306 with no luck. exFAT partition is unsupported and samba isn't broadcasting the drive on the local network. I tried with and without usernames. I can connect via IP but can only view the contents of the drive. So same as before.

Maybe I'll try to rollback to end of 2019 sometime soon.
