hard drive – What can cause a removable hard drive to turn off automatically?

I have an external hard drive plugged in via USB port 2, it was bought 6 months ago and it works well, except that today strange behavior occurs with the drive as it unexpectedly turns off, without me ejecting it.

I am using Linux and do not know what is the possible cause of such behavior.

Unable to mount an SSD hard drive on OSX Catalina

I connected a brand new Seagate USB SSD (Backup plus Slim) to a working Mac Book Pro 10.15.2. It went up the first time, I could see it in the Finder and I was able to run the Mac startup program on the drive. However, it didn't seem to work, so I disconnected the player. I thought I ejected it correctly but not absolutely sure.

Then when I plugged it back in, I couldn't see it Finder. I also tried it on a Mac Mini running 10.14.6 but also couldn't see it in the Finder. Back on the Macbook Pro, I tried Disk Utility. He found the disc, but it was grayed out and unmounted. When I tried to mount it, I saw the following error:

Could not mount “disk2s2”. (com.apple.DiskManagement.disenter error -119930868.)

By doing a Google search, I found this discussion, which indicates that it is a Catalina problem. I have not seen any helpful responses.

I have been trying to wait for hours for it to repair and reboot my machine, but it looks like the drive is damaged. How can I fix it?

Bitcoin core – Bitcoind ERROR "Disk space is too low!" to refer to RAM or real hard drive?

After finishing the "Initial block download", I had to reindex:

(BTC_Core_Expmnt)# bitcoind -reindex -datadir=/mnt/BTC_Core_Expmnt

The debug.log showed that everything started well; and the start of the process:

(2020-01-20T07:43:41Z Loaded 119369 blocks from external file in 6005ms
2020-01-20T07:43:41Z Reindexing block file blk00001.dat...)

Then a little later, this:

(2020-01-20T09:05:59Z Reindexing finished)

But Bitcoind continued to grind … Well, what is all this? ::

(2020-01-20T09:05:59Z Pre-allocating up to position 0x100000 in
(rev00000.dat 2020-01-20T09:05:59Z UpdateTip: new best= 
(height=1 version=0x00000001 log2_work=33.000022 tx=2
(date='2009-01-09T02:54:25Z' progress=0.000000 cache=0.0MiB(1txo))

Anyway it happened at this point:

(2020-01-20T09:59:00Z UpdateTip: new best=
(height=359645 version=0x00000003 log2_work=82.893764 tx=71128141
(date='2015-06-06T07:25:10Z' progress=0.143166

Then it fell:

(2020-01-20T09:59:00Z *** Disk space is too low!
(2020-01-20T09:59:00Z Error: Disk space is too low!
(Error: Disk space is too low!
(2020-01-20T09:59:00Z Failed to connect best block
( (Disk space is too low! (code 0)) )

Which is strange, because there should always be 20 GB of free space, because the size of
BTC_Core_Expmnt is supposed to be 300 GB.

(BTC_Core_Expmnt)# du -h
102M    ./blocks/index
275G    ./blocks
56K     ./bitcoin-
60K     ./bitcoin-
64K     ./bitcoin-
73M     ./bitcoin-
8.0K    ./bitcoin-
440K    ./bitcoin-
74M     ./bitcoin-
16K     ./lost+found
3.4G    ./indexes/txindex
3.4G    ./indexes
914M    ./chainstate
280G    .

Is 300 GB not enough in 2020 to run a full node? I thought it would do the trick. But, ask for helpful advice because I don't see anything wrong with debug.log.

assembly – Format hard drives in a manageable way

is there a sample code to check the available drives and format the one selected on the internet IN ASSEMBLY?

NAS hard drives operate constantly without known work – what does it do?

What is the reason why my NAS (Wd Mycloud Mirror) hard drives are always working, even if there are no read / write operatines from other devices?

I have a NAS (Wd MyCloud Mirror) connected to my router, used for backups. Functions as such. However, I noticed that he was doing sth. constantly, even if I'm not aware of a job to do. Specifically, I hear the disks making the typical hard drive noise (for hours every day), and the green light on the Ethernet cable port is blinking.

The following devices could have access to the NAS (via the router), i.e. potentially perform some r / w operations:

  • router: Fritzbox with the current firmware (i.e. regularly updated). VPN configured for my laptop, which is not used when I am at home and see the problem. The connected DECT phone must not access the NAS. No other changes that I am aware of. IMHO, you don't need Fritzbox to work on NAS.
  • PC running Win-10. Even if no backup task is running, the problem persists. When the Ethernet cable is removed, the LED stops, but the sound from the hard drive persists for long periods.
  • WiFi devices such as mobile phone: the problem persists even if WiFi is disabled on the router.
  • WdMyCloud itself: only a small fraction of the reader is used. New files are written from the PC only every few weeks. Therefore, I assume that any potential indexing / mirroring / verification should be done within hours or days and not persist.

Firstly, I would like to understand what this thing is doing, and secondly, I fear that a strange process is a common thread for my data, and that a constant workload on the hard drive could shorten the service life.

wallet – Ledger 8 pins how hard to guess in terms of entropy?

ledger has a max. 8 digital pins to unlock it as far as I know.

I'm very interested, can anyone tell if (given a method / resources) it is possible to guess this 8 digit pin in 3 tries (except luck)? Because if I understand correctly after the 3rd try, the device will reset.

Is it too difficult or possible?

And if you know, could you calculate (or tell me how) the entropy for this case (8 random numbers, 3 tries)?

Thank you

hard drive – replacing the HP Proliant DL180 G6 HHD

One of the HHDs of our HP Proliant DL180 G6 has gone bad, how should I proceed to rebuild the bay? Does the HHD have to be an HP or can it be a reader from another company?

I replaced the drive with a Seagate HHD of the same size and waited four days for the drive to be rebuilt, bay control did not show any indication of rebuilding. I put the failed drive back into the server and the HP bay showed a rebuild, I registered to the server in the next few hours and the HHD was still at zero%.
