The answer is IDEMA formula, as described in the IDEMA Standard LBA 1-03 specification (specs available here, or direct PDF download). LBA counts = (97,696,368) + (1,953,504 * (Advertised Capacity in GBytes – 50)) LBA counts = (97,696,368) + (1,953,504 * (500 – 50)) LBA counts = 976,773,168 Capacity in Bytes = 512 Bytes * LBA counts Capacity in Bytes = ...

I have had this happen to me once before. The solution on that machine was to edit the boot order of the BIOS, so that the hard drive was the first boot option (In fact, if I remember rightly I moved the USB device to the very last option in the boot order priorities). After saving that, I booted from the USB by pressing F10 (motherboard specific) and doing ...

SMART is good for an overview of the drive health, but it is by no means perfect or 100% reliable for detecting a failing drive. On the contrary, I've had some drives with a perfect SMART reading, but barely able to keep a connection to the machine for over a minute. What you've described does sound like a failing hard drive, at least, certainly not a ...

It seems that the high failure rate of the Seagate ST3000DM001 model 3TB hard drives is fairly well known in the tech world. While Seagate seems to be willing to accept returns of defective drives in exchange for a replacement drive, some of those replacements are also failing as well. If you have purchased a Seagate ST3000DM001 3TB hard drive that you ...

You can try creating a Linux Live USB in another computer, and then boot it in the damaged one. Use Linux to delete the whole damaged volume and reinstall Windows normally.

Using dd with bs=512 can really cripple speeds, I'm imagining it's like trying to run a mile but taking 1 inch steps. Using a bigger value like bs=10M or bigger should be a lot better. Anyway, files are probably not all contiguous so trying to cut out just the right parts of the drive with dd won't work for every file, and (probably, not too sure how HFS ...

RAID-10 consists of a stripe of mirrors. As long as one disk in a mirror is functional, you're fine. If in the below example you lost Disk 0 and 1, you would lose data. If you lost Disk 0 and 2, your data would still be accessible from the mirrored stripe. Picture from Wikipedia. Since RAID-01 is a mirror of stripes, it offers the same redundancy. The ...

Ok it apears that the reasons it was reading and writing large amounts of data was due to my Raid 1 drives be desyncranised. good news is i fixed it the bad news i broke my raid so i now have 2 seperate drives :/ little update: I removed one of my drives from the mirror raid, formated it and then added it back to the mirror drive. Just had to wait for it to ...

As aked this does not make sense: Can Iset up a RAID of 150 GB velociraptors for performance. Yes. Trivially easy. And it can be done both in software or with hardware. For max performance you probaly want stripe/RAID1. (AND RAID 0, RAID 1 and combination like RAID10 work fine without huge CPU loads.) and then make it so where they automatically ...

I've just tested on an E6540 and the WWAN port accepts mSATA SSD. Windows was able to boot up from it.

You can't practically "low level format" a modern hard drive. In order to do this you would need to get special information from the drive vendor which is not commonly available, and even if you do get this, low level formatting will not solve your problems - indeed it will make it worse. Whoever was advising you is unqualified to be giving you advice, as ...

The best thing you can do is delete the data off the disk. It will take more time to do anything else than its worth. Setting up file or disk encryption takes time. And of course you have to test to see if it works. That takes even more time. It takes a fraction of a second to delete the data. Even if the data is secured, it can be taken and ...

Clone your Windows partition. Shrink Debian partition and resize Windows partition to according to your needs Format Windows partition and restore from clone. If you aren't sure about which tool to use I can recommend PartedMagic as it contains all the tools you'll need. (Clonezilla and GParted)

The BX200 has slow TLC NAND, with a 6GB of faster write cache on the 480GB model. After the cache is exhausted, it will write at the actual speed of the TLC NAND. I can think of two possibilities that could be affecting your benchmark: Bonnie++ is writing more than the 6GB, after which it will continue to write at the lower throughput. Then bonnie++ is ...

Quite simply your motherboard is too old. Buy (or use) a smaller drive as your boot disk and use the new one for bulk storage. From Table 3: Windows support for combinations of boot firmware and partitioning schemes for the boot volume at Windows support for hard disks that are larger than 2 TB Microsoft does not support BIOS + GPT as a boot volume, nor ...

You haven't said how old your motherboard is, or what features it supports. Mokubai may be correct, but if your computer was introduced in mid-2011 or later, it may already use UEFI firmware, which supports booting from a GPT disk. Even a few older motherboards use EFI. You'll need to re-install in EFI mode, though; most EFIs include a Compatibility Support ...

Having a RAID array is, at least from what I have seen in my professional career, the best option for redundancy - I also want to mention that having a RAID is not the same as having a backup - Even with a RAID system, having a backup of the RAID is definitely great practice. As for alternatives, you have options such as Software Raiding (ones that are ...

No, just disconnecting the hard drive will not erase the contents of the drive. Of course, if the drive is fully encrypted, the contents won't be accessible to anyone. But they'll still be there.
