Software recommendation are out of scope on Superuser, but that is basically how any recovery software works anyway. As long as the content of the file is not overwritten it can be recovered. A "backup" of the file allocation table won't give you any benefit. This being said, I never heard of this feature at least not in a consumer software. But if ...

So: The solution for me was: I found the LOST directory. There all my data were. However not in the correct file format. On Linux it was no problem to open these (as Linux doesn't care about the ending). PDFs however aren't restored 100% correct. Just changing the ending to .pdf does the thing for Linux. However the friend of mine using Adobe Reader cannot ...

Partial answer: There are quite a few different ways to get the drive serial number. (Read the ATA, ATAPI and USB storage specs for details). If you want to find out which particular way is used for the symbolic links, you need to dive into udev, find out which command is used to create those links (very likely blkid), find your version of blkid, and read ...

Your disk may be dying - save your data and replace it. The SMART data shows a high Reallocated Sectors Count value of 1,744. This parameter is defined as: Reallocated Sectors Count S.M.A.R.T. parameter indicates the count of reallocated sectors (512 bytes). When the hard drive finds a read/write/verification error, it marks this sector as "reallocated&...

For me it was an old sata cable! i gave it a jiggle at the connection to the port on the mobo and it miraculously worked again with no issue.

You can find many guide how to boot ISO by adding a GRUB custom entry. Most of them addresses Ubuntu which uses casper. I have to have a Solus iso. I used an modified entry for CentOS. It booted but initrd-switch-root.service failed, sending me to root shell. Anyway, UNetbootin can write iso to HDD. See this. Make a partition, burn the ISO on that partition ...

By hot, you mean how hot? My laptop HDD is 10 degree celsius hotter than my room, and it's spinning in 5400 RPM (I guess). It is supposed to be hot. You boot and use Windows 10 from SSD and that doesn't use the HDD (until you start using drives on HDD). When you boot Ubuntu, it spins the HDD immidietly, write stuff and things get hot. HDDs are hot compared ...

If Windows is installed with UEFI, you better turn off legacy boot, and boot in Ubuntu installation media and make sure it is installed as UEFI as well. Because if it is installed in Legacy mode, the it's harder to handover boot to GRUB. If its UEFI, you can just point to it from BIOS, like in screenshot. By the way, using UEFI requires a FAT partition at /...

you just need to set HKLM/SYSTEM/HardwareConfig/{..guid..}/BootDriverFlags = 0x14 - these BootFlags correspond to CM_SERVICE_USB_DISK_BOOT_LOAD + CM_SERVICE_USB3_DISK_BOOT_LOAD.

I had this problem with a Hitachi Touro 2TB external USB hard drive. After trying lots of possible fixes, the only thing that worked was to enable USB Optimization in my Intel DQ77MK motherboard BIOS settings. Here's a description of this setting: If Enabled, USB devices (keyboards and drives) will not be available until after OS boot, but BIOS will boot ...

The partition table (aka "disk label") on that disk is unrecognizable. It's either missing or corrupted. Why it could be missing: It's typical for brand new disks Wiped (or partially wiped) disks don't have one The filesystem is created on the entire disk, without partitioning - this is unusual but sometimes makes sense, especially with ZFS The ...

There's a good post over at brashear.me which creates a btrfs partition stored as a file. The partition supports compression and can be used by ddrescue transparently. The blog post is reproduced below, should it ever become unavailable. As disk sizes explode, I've found myself having to mirror disks which I don't have enough storage for. My tool of choice ...

I got lucky, the next day, after trying several times unplugging and replugging it, removing it from the device manager, waiting for Windows to add it again. Finally just left it plugged in for a while, all of a sudden, it appeared again. However, when doing a backup, some files were unable to copy. So I am sure this is a hardware issue and will replace the ...

Please check if your disk is recognized using a different machine or a different operating system.

You need to use a program called "Hugo" by Western Digital. You can't just download it from their site, but if you contact them with a support request after 1-2 weeks someone will contact you and send you a download link. Then what I did was the following, to change formatting for an 18TB HGST (now WD) drive from the default 512e to 4Kn C:\Program ...

The short answer is no. The drives that report raw read error rates will also report uncorrectable errors, you should only be concerned if the uncorrectable error counter increases. Also to add errors can be caused by factors outside of the drive itself, bad SATA cables, bad cable connection, faulty ram, faulty DMI bus and faulty controller are all possible ...

They don't need the be blank. They will be re-formatted by the RAID controller anyway. Just make sure the new disks are bigger than the old disks. Have a care though (this is a general concern with RAID setups, especially RAID1 and RAID5). During the re-build of the first new disk the other (old) disk will receive a very heavy read load, because it will have ...


2

No. The RAID array doesn't care. During setup of the array the controller will trigger a process to copy the contents of the first disk to the second but it won't care what is on either disk to begin with. This may seem like a waste of time to you, but the controller has no idea what is real data on the disk and what is not. The goal of RAID 1 is to achieve ...

The only way you can accomplish this if both drives are in a RAID type of configuration. This can be achieved using a hardware RAID and software RAID. If you use a hardware RAID, you will have to format all drives that you want to use before you can setup a striped RAID. Software Raid can be converted into a dynamic disk without format though. For Software ...

I have done this with a similar device, the AD5SAHPM-EA - 5 x 1 eSATA Port Mulitplier. I connected it to my Raspberry Pi. I had to struggle to fund a USB to eSATA adapter that supports port-multiplier, but I found one; this one on eBay worked just fine. However you will need an eSATA to SATA cable, but those are easy to find; here is an example. Keep in mind ...

This is exactly as intended. By convention, PCs boot from the C:\ drive. This is mapped at boot. It is a variable, not a fixed assignment. Each OS then carries its own mappings as to what letter any other mounted volume is assigned.

You'll need to purchase a hard drive and install an operating system. You won't be able to buy a pre-imaged hard drive. When shopping for a hard drive, you can check the specs of your laptop here. You'll need a SATA drive (preferably an SSD). If you're looking at an M.2 drive, make sure it is a SATA M.2 drive and not an NVME M.2 drive.

There may be nothing at all wrong with the drive. It may not be encrypted… but Macs can't read Ext4 without 3rd party software. There's a freeware option FUSE, but it's always been unstable, so YMMV. If you have Homebrew installed, then FUSE is accessible with brew install --cask osxfuse brew install ext4fuse Alternatively, I'd recommend Paragon's ExtFS for ...

First try to make a disk image, e.g. with Macrium Reflect or one of the many alternatives. This may protect any residual data, allowing you to recover it from the image, rather than that HDD. You might try examining the drive with DiskGenius, which can recover data from a number of file management systems, including NTFS, ext4 and others. Another option, if ...

#0. If it's an old HDD, check if it's in a good condition first. HDDs are quite delicate and you may not want to entrust your data to one that's showing signs of aging or nearing failure. Read drive's SMART parameters. This data is collected by the drive itself and will tell you a bit about its condition. In particular look at raw values for reallocated and ...

The connection is likely irrelevant. eSATA and SATA are likely to have exactly the same performance for mechanical HDDs. Your problem is more likely a feature of the spinning platter of mechanical HDDs. Mechanical HDDs use zoned bit recording with a fixed (ish) physical sector size. What this means is that at the outside of the disk there are more sectors ...

This is going to look like a list pf product recommendations, I'm afraid… …but Mac can't natively write to NTFS, so anything that could 'fix' the drive is going to need to first be addressed through an NTFS enabler. [This is technically possible for free using FUSE, but it is often flaky & I wouldn't trust it for any critical task.] Paragon NTFS for Mac ...

First: stop what you are doing! Make a backup of the disc (e.g. sector by sector image). Then try to recover either the backup or the original. In case there is a chance the original disc is failing make a second backup and try to fix the / recover from the first backup (in case the recovery process messes up the data on the first you can recreate it from ...

This is a good problem description: Initially (yesterday), when trying to boot an ascii screen came up on the monitor that asked questions about BIOS etc. Your mainboard battery most likely failed. Enter your BIOS, take a note of all settings or save your settings to a secondary drive (not your RAID array), maybe an USB stick. Replace the battery after ...

The disk seems fine. It has fewer events than your other disk. The value of 100 means no events, so nothing much to remark about the disk, except the "G-Sense Error Rate" which is 85. G-Sense Error Rate is defined as: G-sense error rate S.M.A.R.T. parameter indicates the number of errors caused by externally-induced shock or vibration. ...

When dealing with a data recovery issue there is no shortcut other than duplicating the total drive. Use ddrescue, a free and open source tool from the GNU foundation. It is contained in many live Linux distributions like in GParted where the CD ISO is only 300-400MB. Do not confound ddrescue with dd_rescue from Kurt Garloff. dd_rescue has a different ...

You will have to run the clone (disk to local disk clone) with the -sfsck option. This bypasses the checks if the source is OK and just tries to copy everything without checking. If that doesn't work (too many read-errors) get a GPartED Live USB. This contains (among other things) also the command-line utility ddrescue which is specialized in copying from ...

There are many tools to erase a drive but most are rather slow. The fastest way I found to securely erase a drive (SSD or HDD) is to write random data to it by using cryptsetup. On Linux you can easily do it like this: DEVICE=/dev/??? # put your device ID here cryptsetup create cryptedDEV $DEVICE # use any pass, no need to remember it ...

(This is a copy from my answer over at Software Recommendations) I've been doing initial tests with pCloud for this use case.

No problem, I removed the SSD from external hard drive box and plugged in with a SATA to USB adapter and SSD is still working. It looks like only external hard drive box is broken.

I had a similar problem with my SSD. I had occasional file corruption and once or twice a month, the PC would not boot. All the drive tests showed the drive as perfectly operational. I eventually swapped the drive with another one. Since the time between faults was long, it took a while to notice I had the same issue on the new drive. This pointed to a ...

Change the SATA cable. Clean the sockets with contact cleaner then ensure the new cable has no tension on it once installed. SATA cables hate to be pulled out of square.

Your requirement, "to increase the sdd1 partition to 10g from current 1K size" Your first example successfully increased the /dev/sdd1 partition from 1K to 20GB (100% of the disk). The others all failed because the disk partition was already resized. Now, since you actually wanted to resize the partition to 10G instead of the full 20GB disk we need ...

Thanks @TomYan for the answer. To allow the automount to work with UUID, you must use the UUID without the double quotes. Indeed it works.

Use any checksum generator to compare the integrity of your copy target by comparing the checksum of your source and your target file. What is maker and model of your external hard drive? Is it a 2,5'' drive without proper power supply?

(OP) Thanks to all who responded. Great bunch of knowledgeable folks here. I'm accepting DrMoishe Pippik's answer as the one that made up my mind: it wasn't the platters' magnetic material that attracted the magnet so strongly, but rather the head-positioning magnet. That's a relief to know. I'll put this drive back in service. Cheers.

The programs could be throttling due to the relatively slow read/write speed via the USB cable that is connecting the computer with the external hard drive. The OS could also be throttling the CPU because the two running programs are causing it to overheat, but this is less likely.

Essential system files are all in "Macintosh HD". User files are in Macintosh HD - Data". As you appear to have two of those, you can delete either. One of them, presumably the larger one, is likely to contain files you had before the repair. You can use Disk Utility to mount & inspect its contents. If there's nothing on there you need, ...

You’re asking the wrong question, I think. Is making a small update to a large file faster than rewriting the whole file? Yes, it absolutely is. It is faster on a HDD, it is faster on a SSD, it is faster on NTFS, it is also faster on a Copy-on-Write filesystem (not that Windows has any). You can even update a single byte, because that is what the operating ...

You are not refreshing anything, you are in effect removing the s: disk with the command subst s: /D. Any Explorer instance that was showing the s: disk will terminate immediately. Your second subst command creates a new disk, and Explorer knows immediately about it. But this is a new disk that has now to be explored anew.

You must have set the password and perhaps forgot it or do not remember setting it up. I use Lenovo machines with BIOS and Disk passwords. Lenovo does not set up passwords on BIOS or on the Disk on their machines. Because of this, they cannot help with passwords. If you cannot remember the password, then you must replace the disk in the computer. There may ...
