[SOLVED] External USB Drive formatted in ext4 is always working

I recently bought a new external USB drive for massive storage (a Seagate Expansion 4TB), but I have a question now. I saw that when the unit is working the flash led is blinking, and when the unit is on "stand-by" (or something like that) the flash keeps steady.

So when the unit is mounted in Linux the led keeps flashing all the time. On windows, the led blinks just when the unit is working (reading-writing). The led stops flashing after a while.

I'm afraid that something could happen to the drive because of this. What do you think?

Re: [SOLVED] External USB Drive formatted in ext4 is always working

I think that the disk should behave the same under Linux and Windows. Is there a program accessing the disk under Linux? Maybe some indexing tool? I believe KDE may have such a tool running by default… (But I use Xfce so I’m not sure.)

Re: [SOLVED] External USB Drive formatted in ext4 is always working

I checked the Nepomuk settings and I I disabled it to confirm, but the led still blinking. It looks like some program is using it, but I don't know which one... I will try a Live CD to see what happen.

Re: [SOLVED] External USB Drive formatted in ext4 is always working

I checked with a GNOME distro Live CD <Fedora 16>, but it's the same. The led keeps blinking all the time when the unit is mounted. Just as I said, in Windows doesn't happens the same. For this reason is that I'm affraid that something happens to the drive. If someone has a theory about it, I would like to read it.

Probably just the lazy ext4 init, it will stop after it finishes what it has to do.

First thing I would try is hdparm.

I checked and you're just right. I tried mounting a NTFS partition of a USB drive, and after a while the led stops blinking.

I will check that.

Re: [SOLVED] External USB Drive formatted in ext4 is always working

It was just the ext4 initializating the i-nodes tables. I formatted using:

sudo mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 /dev/sdXY

to see when the initialization was finished, and after that, it's alright.

This is because ext4 doesn't initializate the tables during the format, but it makes on the first mounting of the partition.
