    Several Reallocated Logical Sectors - best to clone or image?


    My Toshiba MQ04ABF100 HDD has been horribly slow for a long time now. I've recently started to try and see why, and the HDD is often running at 100% according to Windows Task Manager. It's frustratingly useless half the time.

    I've run some tests with CrystalDisk and GSmartControl, and it has several reallocated logical sectors. The first test a week or so back showed about 75, but now it's up to 83. Obviously the drive is starting to fail.

    The laptop is an Acer Aspire A515-51-54XM, with 8GB DDR4 RAM, and an i5-8250U processor. Windows 10 Home 1903 (build 18362.592) with all newer updates blocked. There don't seem to be any hardware errors elsewhere (or at least Device Manager isn't showing any warning icons), so I'm assuming the bad sectors are what are crippling the hard drive. (maybe it's trying to check and double-check before writing anything now??)

    The only "Windows-type issue" that I've noticed is that sometimes the laptop will just fall asleep. Changing power settings has no effect. This has been happening for several months now, and I've resorted to using LeoMoon Session Guard to keep it awake. For the most part this has 'solved' the problem.

    Anyway, I've ordered a SATA WD Blue SSD (1TB) which should arrive this weekend, along with a SATA-USB3.0 cable to connect it with for cloning. I figure hopefully it's just the disk, and if not then at least I'll have an SSD to swap into a new laptop if I need to buy one.

    I have lots of software installed on this laptop and really don't want to have to go through reinstalling everything. If a clone/image would be stable then that's probably my preferred option. I'm also not at home where I have my desktop and other external hard drives to work with. I'm abroad and stuck here for a while due to not wanting to travel right now.

    I have a couple of questions about how to proceed:
    If I clone onto the new SSD, will the bad sectors also get transferred over, thereby showing up as errors on the new drive?
    Would those errors, if they do get copied, cause problems later?
    From my Googling, I've seen that not all cloning software will deal with bad sectors (Easeus, AOEMI, maybe Clonezilla, will?)
    Would it be better to clone the current HDD or to make an image of it? (one of my searches on here mentioned imaging might be better)
    Should I not even bother trying to clone/image, but instead attempt a fresh install, despite having to reinstall tons of stuff?
    If so, would my current recovery disk work on a new laptop and how would I best do that?

    Does anyone have any insights on my best course here? Or maybe there are even other issues I've not thought of?

    :)

  2. How a harddisk performs with reallocated sectors

    I want to ask how a hard disk will perform with reallocated sectors compared with 0 reallocated sectors if anyone knows, my hard disk has 1200 reallocated sectors and they have not been growing so my question in general is if the reallocated sectors may
    impact the read and write speed I'm curious because theoretically I understand that the reallocated sectors are no longer used by the hard disk so the harddisk should write data on a new surface so I don't understand why performance should reduce unless the
    reallocated sectors increase daily of which my hard disc i used formatting tool to write Zeros and ones to permanently erase everything beyond recovery so I'm certain start my hard disk is written data completely on a new surface or new sectors. Does anyone
    have another opinion about a hard disk reallocated sectors and performance-related issues

    How a harddisk performs with reallocated sectors

    Hi TeshFlavour

    The only way reallocated sectors cause performance degradation is if your system is reading a file form your hard drive sequentially, then the head meets a reallocated sector, the head must be re-positioned to read the replacement sector that was allocated

    On most PC's you will never notice any performance hit due to reallocated sectors . . .

    You will not really notice any degredation on your PC unless system files are positioned on your hard drive just before a reallocated sector and honestly, you would be just very unlucky if that happened . . .

  4. Several Reallocated Logical Sectors - best to clone or image?

    What do reallocated sectors mean?

    S.M.A.R.T. indepth online analysis of my old maxtor 40 gb (on the P4) says:

    18% fitness
    99% performance

    and.......

    NOTE : your hard disk has 399 reallocated sectors (this value is very large and your hard disk should be replaced). Hard disks do have spare sectors (usually from 256 up to 1024) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degradated performances (because remapped sectors are in different places of the disk than the original ones and the head needs additional moving). If reallocated sectors grow over time, you might encounter some serious troubles. A backup of the most important data is suggested anyway.
